Zhang Jiguang, Wang Yingwu

2010, 32(4): 309-313. doi: 10.11781/sysydz201004309

Abstract(1779) PDF-CN(1449)

Abstract:
There was clear standard for classification of structural elements in two basin types both depression and fault depression.However,it was insufficient due to division of structural elements in small sedimentary basins was showed multiple gradation,confusion with second-level of structural elements and variety of nomenclature.Therefore,a proposal reducing gradation and naming second-class structural belt according to their forming mechanism in small sedimentary basin was put forward for the convenience of work.Avoiding a structural element with various names or same name for many structural elements,difference between region and belt must be paid attention to.It was suggested that the names of sag belt,fault depression region and synclinal region etc would no longer to be used.

2010, 32(4): 314-318. doi: 10.11781/sysydz201004314

Abstract(1526) PDF-CN(841)

Abstract:
The Upper Triassic Xujiahe Formation is a reservoir forming system with self-generation and self-storage.In Hebaochang region of the Sichuan Basin,the thickness and range of sand rocks is relatetively larger in the Second Member,Fourth Member and Sixth Member of the Xujiahe Formation.However,the reservoir rock mainly has low porosity and low permeability.According to the capillary pressure curve,the capi-llary resistance of the secondary migration of gas is about 2.5 MPa to 3.5 MPa.Heights of gas column are between 150 m and 300 m.Because of the gentle regional structure,gas accumations are mainly controlled by the sand body distribution and reservoir properties.Although the excellent reservoir rock has less capillary resistance,the distribution area is relatively small,and usually belongs to lenticular or strips sand body.The secondary migration of gas depends mainly on the gas expansion and the gas accumulates in nearby regions.

Abstract(1956) PDF-CN(1295)

Abstract:
The oil-and-gas fields discovered so far in the Northern Jiangsu Basin mainly distribute in the Gaoyou,Jinhu and Qintong prolific sags locating in the Dongtai Depression which is in the south of the basin.The formation conditions are as follows: 1) During the migration of subsidence center from west to east in the basin,the sustainable and rapid subsidence type of sags such as Jinhu,Gaoyou and Qintong are created with thick source rocks,premium quality organics and high degree of thermal evolution;2) In the west part of Jinhu and Gaoyou sags which locate in the entrance area of big rivers to lakes in the west of the basin,the favorable Funing Formation reservoir facies belt corresponding to Fu₂ Formation premium source rocks is generated.While in the east part of Qintong and Gaoyou sags which locate in the center of the basin,in addition to many favorable combinations of source-reservoir-seal rocks formed with primary oil and gas in the lower part,the vertical migration of oil and gas is fairly dynamic,and the upper secondary oil-and-gas pools have conducive reservoir-forming conditions;3) In the resi-dual depression area of the Wubao movement,namely the Gaoyou,Jinhu and Qintong sags,source rocks are buried with great depth,resulting in high degree of thermal evolution,rich abundance of oil and gas,and good development of secondary oil and gas reservoirs;4) In the central and west sags such as Jinhu,Gaoyou and Qintong,sedimentary volcanism is significant for major hydrocarbon source rocks of Fu2 Formation.Surface thermal environment and abundant inorganic nutrients help grow rich lower hydrobiont in this area and develope premium hydrocarbon source rocks.Meanwhile,magmatism stages for the 3 sags are 3-4,with high geothermal gradient,which is conducive to high degree of thermal evolution and conversion yield.

2010, 32(4): 326-329. doi: 10.11781/sysydz201004326

Abstract(1515) PDF-CN(915)

Abstract:
There are many rifts and depressions with rich oil and gas in the south of the Songliao Basin.Shiwu Depression and Changling Rift(depression) are the geological units with rich oil and gas,and a number of small and medium oil-gas fields had been discovered.Research suggested that there are two types of rift stratum and depression stratum petroleum systems.Oil-gas reservoir of rift stratum is mainly controlled by the efficient volcanic reservoir and low porosity-permeability of the reservoir.Structural reservoir of volcanic rocks and low-permeability sandstone reservoirs were formed composite with structural.Depression reservoir was controlled by sand distribution of delta front,forming structure-lithology reservoir at a favorable context.Studies suggest that exploration fields of rift stratum include: volcanic rocks reservoir,stratigraphic unconformity reservoir,steep lithology reservoir and metamorphic rock reservoir of bedrock.

Abstract(1750) PDF-CN(896)

Abstract:
The Qiangjiang Sag lies in the central part of the Jianghan Basin and is the most proliferous depression for hydrocarbon accumulation in the basin.The Qianjiang Formation has been maturely explored,so the litho-logic hydrocarbon accumulations now become the primary exploration targets.In this paper,based on analysis of development and distribution of lithologic hydrocarbon accumulations in the Qianjiang Formation,it is suggested that the favorable lithlogic hydrocarbon accumulations occur in structural slope belts,structural reverse areas,fault-developed belts and flextural belts.The main strategy and method for further exploration of the lithologic accumulations in the Qianjiang salt lake basin are to develop technologies for identification and evaluation of lithologic traps and to develop techniques for rework of thin-bedded oil layers,through development of high-resolution 3-D seismic technologies.

Abstract(2057) PDF-CN(1120)

Abstract:
The strata thickness from Second Member of Jialingjiang Formation to Leikoupo Formation in the Sichuan Basin is over 1 500 m.It is composed of dolostone,anhydrite,halilith and interbedded limestone,among which the dolostone is one of the main gas reservoirs in the basin.In the early Jialingjiang stage,the mountain system around the Sichuan Basin keeps uplifting,and the base depresses and dips eastwards.Periodically dry and hot weather makes the basin turn from open shelf to constrained basin.In the early-middle Jialingjiang stage,dry and hot weather makes sea water within the basin concentrate.A set of dolostone and anhydrite formation deposits at the lower land of Jiannan and Wanxian.From the late Jialingjiang stage to the Leikoupo stage,the Jiangnan old land uplifts rapidly and compresses northwestward.The underwater uplifts in Qiyaoshan and Luzhou-Kaijiang are formed,which drive the basin to migrate westwards.The basin with deep depression and high salinity is formed and isolated from open sea.A formation association dominated by dolostone,anhydrite and halilith is massively deposited.Locally,there exists glauberite and polyhalite.The dolostone reservoirs develop dissolved pores in addition to inter-crystal pores,and the over-lying anhydrite and salt rocks are good regional cover rocks.

Abstract(2432) PDF-CN(1460)

Abstract:
It is a basic geologic issue whether the Lianglitage Formation of the Upper Ordovician,southern margin of Ketake Uplift,Tarim Basin,is or not consists of sedimentary assemblage of reef-shoal,just likely to counterparts that occurs in northern margin of Ketake Uplift.Based on the microfacies analysis of carbonate rocks in the cored intervals of Lianglitage Formation in Well Zhong-2,six microfacies records of bioclastic-bearing algal pellet micritic,bryozoans and coralline framestone,bindstone,bafflestone have been recognized,as well as of six major stacking patterns of reef-shoal,reef-shoal-mound,coarse pellet shoal,beach-algal mats,algal or bioherm mound-algal mats,algal mats-subtidal low energy.From lower to upper cored intervals of Lianglitage Formation,the vertical facies distribution are respectively indicative of a gradual deepening trend,a sea-leval fluctuation and two shallowing upward succession carbonate cycles,and account for a serial of stacking pattern of pellet shoal,algal or bioherm mound and reef framestone in the first three cored intervals,with the prominent of highstand progressive system tracts of reef-beach and retrograde terrace reef-shoal developed during sea-level rising period.

2010, 32(4): 353-357. doi: 10.11781/sysydz201004353

Abstract(1558) PDF-CN(1000)

Abstract:
The reservoir of Z1 oil group in W Oilfield has low resistance,high porosity and low permeability.The low resistivity of the reservoir was caused by many geological reasons.In this paper,for the reservoir characteristics of Z oil group,statistics of the reservoir of immobile water saturation has been done,and the genesis of high immobile water saturation in the Z1 oil group in the W Low resistivity reservoirs,as well as the relationship between the immobile water saturation and reservoir resistivity has also been studied.Through the study,in low resistivity layer segment of Z1 oil group,it is found that the main reasons forming a highly immobile water saturation are high levels of fine particles of the reservoir,Poor pore structure of reservoir,Slightly higher percentage of fine pore and throat volume,and the rock hydrophilic.The formation resistivity increases as immobile water saturation decreases.Therefore,high immobile water saturation is one of the important reasons affecting the low resistivity of the Z1 oil group in the W oil reservoir.

Zhu Dongya, Meng Qingqiang

2010, 32(4): 358-361. doi: 10.11781/sysydz201004358

Abstract(1542) PDF-CN(882)

Abstract:
Remarkable silicification was found locally in the Lower Paleozoic carbonate in the Tarim Basin.Euhedral drusy quartz were frequently observed filled or half-filled in the dissolution pores in the carbonate cores of some wells,such as S₁5,S5,S₁3 and TS₁ wells in the north of Tarim Basin and Zhong 3 and Tazhong 1 wells in the central of Tarim Basin.The homogenization temperature of the fluid inclusions in the quartz is generally high,and the maximum frequency of the homogenization temperature is between 150℃ and 190℃.The δ¹⁸OV-SMOW values of the quartz and the δDV-SMOW values of the water in the fluid inclusions in the quartz are between 18.6‰ and 24.14‰,-118.36‰ and-83.39‰,respectively.The rare earth elements of the quartz have features of relatively high content of heavy rare earth elements and considerable negative Eu anomaly.The characteristics of homogenization temperature,hydrogen and oxygen isotope compositions and rare earth elements indicate that the quartz in the Lower Paleozoic carbonate were precipitated from hydrothermal fluid associated with volcanic activity.When precipitating quartz,the hydrothermal dissolved the carbonate remarkably.So that,more attention should be paid to the hydrothermal alteration of the carbonate during the exploration.

2010, 32(4): 362-365. doi: 10.11781/sysydz201004362

Abstract(1567) PDF-CN(932)

Abstract:
Sets of cap formations have generated from Sinian to Tertiary in the Jiangsu Lower Yangtze area,such as-C₁mu,S₁g and K²p.Breakthrough pressure of mudstone caprock is mainly controlled by distribution of micropores and small throats.Statistics have shown that as burial depth increases,breakthrough pressure increases at first and then decreases,indicating the controlling effect of diagenesis on breakthrough pressure.Adsorption and desorption isotherms of microporosity have proved that caprock breakthrough pressure changes due to micropores structures of mudstone during different evolution stages.During the lower stage,mudstone is characterized by pore-type structure and breakthrough pressure increases with depth.During the higher stage,mudstone brittle increases and micro-fissures come into being,resulting in decreases of breakthrough pressure and sealing ability.

2010, 32(4): 366-372. doi: 10.11781/sysydz201004366

Abstract(1649) PDF-CN(1042)

Abstract:
The Lower Triassic Feixianguan Formation reservoir in the Puguang Gas Field of the Northeast Sichuan mainly consists of platform margin oolitic beach sediments.The main lithology is dolomite.The main diagenesis effects include: micritization,compaction and pressure solution,consolidated fill,dolomitization,nascent deformation and recrystallization,solution and structural disruption.Among which,dolomitization,solution and structural compression work as the key effects for reservoir formation.According to dolomite types,order degree and C,O isotope analyses,dolomite reservoir generates in high salinity fluid and quick crystallization environment.It is the result of dolomitization caused by seepage reflux during the penecontemporaneous stage.Three stages of solution effects have taken place in the reservoir.From the early diagenesis stage to the early middle diagenesis stage,pores generated from fresh water solution and primary intragranular pores are filled by consolidations.The present effective pores are buried ones.The burial solution is divided into two stages.The first stage is after structural compression but before oil filling.The second stage is when the filled oil has transferred to bitumen.Structural compression is another controlling element for reservoir formation in the Feixianguan Formation.On the one hand,structural compression is favorable for recrystallization;on the other hand,it forms fracture and cracks crystals,hence provides pathways for acid fluid.In this way,the contact surface for oil and rock is enlarged,which helps the generation of burial solution.

2010, 32(4): 373-376. doi: 10.11781/sysydz201004373

Abstract(2081) PDF-CN(1291)

Abstract:
When the oil is suffered from strong biodegradation,most hydrocarbon component(including sterane) is loss,and the common maturity parameters can hardly play their roles.So,how to distinguish the maturity of the strong biodegradation oil is one of the research puzzles.Based the previous research,this paper takes the Santai-Beisantai area of the Junggar Basin for example,analyses the dependability of Ts/Tm.It is pointed out that Ts/Tm increases with maturity and is hard to be biodegraded,and can be used to distinguish the maturity of different type of crude oil.The bitumen and heavy oil derived from the result that the crude oil at low evolutionary stage suffered from loss and strong biode-gradation.The medium density oil comes from the result that oil at mature evolutionary stage suffered from loss and moderate biodegradation.

2010, 32(4): 377-381. doi: 10.11781/sysydz201004377

Abstract(1418) PDF-CN(774)

Abstract:
Artificial oil mixing experiment is frequently adopted in quantifying mixed oils at present.The author first summarizes the common process of the experiment,and then puts forward 4 questions during experimentation: nonlinear variation of biomarker ratios caused by different maturity of end member oils,invalidation of conventional biomarker parameters under the condition of high maturity or strong degradation degree,being hard to get end member samples in complex geological conditions,complexity of geochemical parameter's changing rules and experimental processes when there are many end member samples.Afterward,solutions to the above mentioned questions are proposed: quantitative analysis of biomarkers,selection of special biomarkers,multivariate data analysis,and computer software data analysis.Finally,a new multivariate data analysis method for quantifying mixed oils is introduced,through which,the numbers,composition and proportion of end member samples could be calculated even without knowing the end member samples or adopting the artificial oil mixing experiment.This method is particularly useful to quantify mixed proportion under complicated geological conditions.

Abstract(1601) PDF-CN(1014)

Abstract:
Well Shinan 31 locates in the north of the Shixi Oilfield,the hindland of Junggar Basin.It's another major discovery after finding the Jurassic Toutunhe Formation reservoir in the Well Shinan 21.The reservoir is in the Cretaceous Qingshuihe Formation with high gas and oil ratio and light oil,while associating with the black biological degradation oil.The article applies entire hydrocarbon geochemical methods to confirm the origin of the oil-gas.It pointed out that the oil and gas was from the Wuerhe Formation source rock in the western Well Pen 1 Sag.It also clarified the oil and gas genetic relationship between Cretaceous oil and gas in Well Shinan 31 and Carboniferous and Jurassic oil and gas in Shixi Oilfield.It established the hydrocarbon formation mode of the Cretaceous reservoir in Well Shinan 31 and pointed out that the chief exploration target in the near future is the oil and gas captured by the transition region between the Shixi Oilfield and Well Shinan 31 during its migrating from south to north.

2010, 32(4): 387-392. doi: 10.11781/sysydz201004387

Abstract(1530) PDF-CN(885)

Abstract:
It is essential to take a detailed study on the geochemical characteristics of heavy oil,which will be useful to conduct the oil-source correlation,the genesis and the development of heavy oil.The oils,which are from the west of Biyang Sag,have been experienced above middle degree of biodegradation.Furthermore,the regular steranes and hopanes have been suffered biodegradation to some extent,which made the common parameters reflected the genesis and maturity of oil ineffective.However,some parameters,which can resist strong biodegradation,such as gammacerane,Ts/Tm and some tricyclic terpane,still can identify the source of these biodegraded oils based on the GC-MS characteristics of 12 oil samples.It indicates that the crude oils in the lower of the Eh₃ formation are derived from the source rock of the lower of the Eh₃ formation,while the source of crude oils in the top of the Eh₃ formation is the mixture of the top and lower of the Eh₃ formation.In addition,some aromatic parameters,which are the component of aromatic hydrocarbon and the relation of triaromatic sterane(C₂₀+C₂₁) /∑(C₂₀-C₂₈) and triaromatic sterane C₂₀/(C₂₀+C₂₈R),can divide biodegraded oils into two types.And this conclusion is also proved by the relation of triaromatic sterane(C₂₀+C₂₁)/∑(C₂₀-C₂₈) and C₂₄ tetracyclic terpane/C₂₆ tricyclic terpane.Moreover,it suggests that there might have different biodegraded mechanisms for the biodegraded oils in the west area,for the same degraded degree of oils have a different distribution of saturated compounds.

2010, 32(4): 393-396. doi: 10.11781/sysydz201004393

Abstract(1905) PDF-CN(1121)

Abstract:
Detailed research with CL and EPMA on carbonate minerals shows that CL intensity on carbonate mineral is related with trace element contents and EPMA beam current,the CL image is correspondent with EPMA element distributing mapping:Calcite CL intensity is related with Mn contents and in less beam current Mn rich areas will emit stronger CL but in larger beam current with cloudy CL image because the exists of Fe that will decrease the CL intensity.The dolomite has a distinctively inner CL image with sometimes showing dolomite rings in less beam current,but with larger beam current the inner CL difference of dolomites disappeared,the CL intensity of dolomites are apparently related with Mn,Fe trace element mapping of EPMA and CL can gives more detail of the carbonate minerals.The CL and EPMA technique can be useful in carbonate reservoir texture,cement sequence and pore evolution analysis.

Abstract(1745) PDF-CN(1004)

Abstract:
The heterogeneity is objective character of reservoir and influences hydrocarbon occurrence,oil production,ultimate recovery factor and economic behavior.How to effectually characterize heterogeneity of the reservoir is a problem researched by geologists all the time.There are lots of characterized para-meters for the heterogeneity of the reservoir.But every parameter involves advantage and shortcoming.In the long-term experience of scientific research process,a new parameter to characterize the reservoir heterogeneity is proposed,which is permeability diversity coefficient.The heterogeneity degree of the reservoir can be characterized completely,truly and accurately by this parameter.Calculation method of this parameter is simple and convenient.The comparability is good,the criteria can be easily established and the computational accuracy is not influenced by sample numbers.In the practical application it acquires preferable effects.

Abstract(1356) PDF-CN(902)

Abstract:
Thermochemical sulfate reduction(TSR) is the major mechanism of gas reservoirs with high content of sulfureted hydrogen.The complexity of TSR mechanism demands further research which needs comprehensive simulation experiment,but different simulation experiments with different instruments lead to great diversity.In order to investigate the influence of instrument material on experimental results,a series of contrast experiments have been done.With the experiments,the followings are confirmed: ①The metal in high temperature and pressure kettle reacts with sulfur to generate metallic sulfide,so composition metal kettle is not suitable to be used as an instrument for TSR simulation experiment;②In high temperature and pressure conditions,quartz reacts with sulfate to generate silicate,so quartz tube can not be used for TSR simulation experiment;③Gold does not react with the reactant,intermediate reaction product or final reaction product,for the limited bulk volume of golden cube,the hydrocarbon product is not enough for testing light hydrocarbon,but it's enough for testing gaseous hydrocarbon components and carbon isotopes,so it is the best option to use golden cube for such kind of simulation experiment.
