Abstract(747) PDF-CN(249)

Abstract:
Since the Yenshanian movement is a peak stage for oil/gas generation of the Triassic source rocks in west Sichuan, the tectonic evolution in this stage would be significant for oil/gas accumulation in the area. On the basis of tectonic settings and sedimentary characters, the tectonic evolution in w...

ON THE DISTRIBUTION OF FLUID PROPERTIES AND GEOCHEMICAL MODEL IN RESERVOIR DESCRIPTION

Xiong Qihua, Fang Chaoliang, Zhang Zhihuan, Ji Fahua

1993, 15(4): 343-349. doi: 10.11781/sysydz199304343

Abstract(740) PDF-CN(190)

Abstract:
With the development of the theory on oil reservoir description, the studies on the distribution of fluid properties and geochemical models have become an important part of reservoir description. In this paper, the case studies were taken from the heavy viscous oil pools in the 1,2,3 sections of the...

THE DISTRIBUTION OF SEDIMENTARY FACIES IN THE CAMBRIAN SYSTEM OF THE YANGTZE AREA

Zhang Xinguo

1993, 15(4): 350-360. doi: 10.11781/sysydz199304350

Abstract(626) PDF-CN(377)

Abstract:
Based on the studies of sedimentology and petrology from 13 field profiles and the comprehensive analysis on the sites of 285 profiles, three regional profiles were established. Furthermore, the sedimentary facies over the whole Yangtze region was systematically studied in detail, which also resulte...

THE IMPLICATIONS OF PETROLEUM GEOLOGY OF LACUSTRINE CARBONATE ROCKS

Zhou Shuxin, Wang Jianguo

1993, 15(4): 361-369. doi: 10.11781/sysydz199304361

Abstract(789) PDF-CN(300)

Abstract:
The petroleum potential, reservoir conditions, the types of oil/gas pools and exploratory method of hidden oil/gas traps developed in lacustrine carbonate rocks were discussed. It is concluded that the carbonate rocks in semi-lacustrine and deep lacustrine facies would be good source rocks;and limes...

ON THE PROPERTY OF THE BASEMENT FORMATION IN THE PALEOZOIC BASINS OF THE YANGTZE AREA

Shan Xianglin

1993, 15(4): 370-384. doi: 10.11781/sysydz199304370

Abstract(719) PDF-CN(331)

Abstract:
The basement duplex structures are widely developed in the Paleozoic basins of the Yangtze Area. The intermediate metamorphic and hypometamorphic basements in the lower structural level mainly consist of the metamorphic rocks attributed to the Archaean-Lower Proterozoic granulite-amphibolite facies ...

GEOCHEMICAL CHARACTERISTICS OF LOW-MATURITY CRUDE OIL IN THE XINJIANG JIMSAR DEPRESSION AND ITS PETROLIFEROUS POTENTIAL

Wang Yutao

1993, 15(4): 385-393. doi: 10.11781/sysydz199304385

Abstract(617) PDF-CN(336)

Abstract:
In this paper, the physical properties and geochemical characteristics of crude oil from No.6 drilling well of the Jimsar Depression were studied. Thereafter, the correlation with adjacent regions were carried out in order to evaluate petroliferous potential in the Depression.

ON THE PARAMETER FOR ASSESSING MATURITIES OF ORGANIC MATTER IN SOURCE ROCKS DURING ARTIFICIAL MATURATION EXPERIMENTS

Li Zhi

1993, 15(4): 394-403. doi: 10.11781/sysydz199304394

Abstract(684) PDF-CN(196)

Abstract:
Vitrinite-rich brown coal was sampled for our artificial maturation experiments to set up a corresponding relationship between telocolinite vitrinite reflectance and heating temperature (R°-T_PY). By using such a relation, we can assess the maturities of all kinds of source rocks during the artificia...

POROSITY AND PERMEABILITY UNDER CONFINING PRESSURE CONDITION AND THEIR IMPORTANCE FOR GAS-RESERVOIR EVALUATION

Sun Tuo, Lin Wanxiang

1993, 15(4): 404-413. doi: 10.11781/sysydz199304404

Abstract(731) PDF-CN(240)

Abstract:
By experiments the authors studied the pressure effects of rock formation on the development of porosity and permeablility and suggested the evaluating and grading mathods of relative physical property parameters suitable to unconventional reservoirs and gas-reservoirs. Furthermore, the sensitive ex...

A NEW METHOD TO CALCULATE THE ANCIENT THICKNESS OF SEDIMENTARY SEQUENCES

Mou Zhonghai

1993, 15(4): 414-422. doi: 10.11781/sysydz199304414

Abstract(837) PDF-CN(281)

Abstract:
As the study and calculation on the ancient thickness of sedimentary sequences used to be based on the data of drilling wells and loggings, the application of the calculation is limited by the number of drilling wells. In this paper, the density logging data is applied combining with the thickness e...

THE TERTIARY SPOROPOLLEN ASSEMBLAGE IN THE JIUQUAN BASIN AND THE PALAEOENVIRONMENT

Abstract(682) PDF-CN(439)

Abstract:
As sporopollen is the generative cell of maternal plants, a paleo-vegetation and paleo-climate may be partially and approximately revealed by using the sporopollen spectrum. However, the characteristics of sporopollen assemblages from various Tertialry sequences in the Jiuquan Basin are approached w...
