1990, 12(2): 99-108. doi: 10.11781/sysydz199002099

Abstract(680) PDF-CN(336)

Abstract:
Basal detachment structure is a major structural style of intraplate deformation. At the end of Permian, Tarim plate drifted northward as a result of the opening and closing of Tethy; on the one hand, the closing of Haixi geosycline in Tianshan was advanced; on the other hand, the convergency and pr...

Abstract:
With the view of the characteristics and distribution of sedimentary facies, the original environments for iso-sedimented rocks,deep-water distant-sourced turbidites in Cambrian of Gannan (South Jiangxi) and Minbei (North Fujian) and shallow water near-sourced turbidites in the upper Ordovician in Z...

A GEOCHEMICAL DETERMINATION OF THE SUBDUCTION OCEAN CRUST IN EAST QINLING MOUNTAINS

Gao Changlin, Qin Deyu, Ji Rangshou, Yin Yong

1990, 12(2): 135-146. doi: 10.11781/sysydz199002135

Abstract(691) PDF-CN(382)

Abstract:
The relic of subduction palaeooceanic crust is recognized in Song Shugou area of Shangnan in the eastern Qinling with the geochemical methods proposed by the authors. The existence of ophiolite suite and volcanic rock zone is the reliable evidence for the determination of subduction palaeooceanic cr...

A SIMULATION EXPERIMENT OF PETROLEUM ORIGIN ON KEROGEN FROM SHALES OF THE LOWER XIAMALIN FORMATION IN THE UPPER PROTEROZOIC

Liu Baoquan, Cai Bing, Fang Jie

1990, 12(2): 147-161. doi: 10.11781/sysydz199002147

Abstract(920) PDF-CN(500)

Abstract:
A simulation experiment was made on kerogen from shales in the lower Xiamalin Formation of the Proterozoic in North China.Certain characteristics and the law of the thermal evolution for the organics from the lower Xiamalin Formation have been revealed in the study.Furthermore, with the basis of exp...

QUALITATIVE EXPERIMENTS ON THIOPHENE COMPOUNDS IN MINERAL FUELS

Wang Peirong, Tan Junxiong, Bao Jianping, Zhao Hong, Dai Yunjian, Zhu Cuishan

1990, 12(2): 162-177. doi: 10.11781/sysydz199002162

Abstract(1336) PDF-CN(239)

Abstract:
The study mainly deals with a systematic qualitative analysis of the thi-ophene compounds in mineral fuels.During the experiments, we obtained the characteristics of GC/MS, reserved the exponential value and distributive pattern.The experiments provide certain basis for detailed geochemical study.

A QUICK PREDICTION OF THERMAL EVOLUTION FOR ORGANICS IN BAYANHUA GROUP OF ERLIAN BASIN WITH THE APPLICATION OF GEOTHERMAL LOGGING DATA

Zhang Wenlong

1990, 12(2): 178-181. doi: 10.11781/sysydz199002178

Abstract(533) PDF-CN(248)

Abstract:
Using the methods of mathematical geology, a criminant function is devel-oped for the thermal evolution of organics from Bayanhua group, based on geothermal logging data. Before the estimation of petroleum generation, a direct statistic prediction for the thermal evolution of organics can be made on...

APPROACH ON INFORMATION FUNCTIONS AND CONODONT PALAEOCOLOGY

Wang Ande, Wang Hengding

1990, 12(2): 182-190. doi: 10.11781/sysydz199002182

Abstract(771) PDF-CN(245)

Abstract:
The strata in the adjacent area of Su-Zhe-Wan (the provinces of Jiangsu, Zhejang, and Anhui) area dated from Changxing period of the late Permian are taken as a rock unit, which, from southeast to northwest of the study area, are successively divided into peri-beach tide-flat fades, shallow water ca...

ANALYSIS AND APPLICATION OF CONCAVE PRESSURE-RESTORING CURVES FOR OIL WELL

Feng Wenguang

1990, 12(2): 191-199. doi: 10.11781/sysydz199002191

Abstract(1044) PDF-CN(288)

Abstract:
A basic formula for concave pressure-restoring curve and two methods of linear analysis are proposed, applying the theory of non-Darcy low speed seepage flow. The results from the two analytical methods are entirely consistent, and several reservoir parameters, i.e the primary stratigraphic essure, ...

STUDY OF THE INFLUENCE OF MINERALS ON PYROLYSIS

Gao Xianzhi, Zhang Wanxuan, Zhang Houfu

1990, 12(2): 201-205. doi: 10.11781/sysydz199002201

Abstract(645) PDF-CN(357)

Abstract:
8 kinds of minerals common in sedimentary rocks are selected, which are mixed with organics (kerogen) to make pyrolytical experiments, so as to study the influence of minerals on organic pyrolysis. The experiments revealed that of the eight kinds of minerals, quartz, orthoclase, calcites and dolomit...

Abstract(696) PDF-CN(231)

Abstract:
The relationship between colours of fossil Polypodiisporites,a widespread fossil spore in Cenozoic of Yunnan, and the maturation of organic matter could be employed to infer the stages of petroleum generation and evolution, and to indicate the favourable horizons and areas for petroleum prospecting....
