Abstract(850) PDF-CN(351)

Abstract:
In this paper, the concept of effective source rocks refers to those of source rocks in which the hydrocarbons already generated have been expelled or diffused out from their mature source rocks. Not only the meth-ods and procedures are introduced in detail to distinguish the effective source rocks ...

ON PETROLEUM SOURCE AND MATURATION CHARACTERISTICS OF THE ORGANIC MATTER OF CAMBRIAN AND MIDDLE-UPPER PROTEROZOIC IN KUANCHENG REGION OF NORTHERN HEBEI PROVINCE

Abstract:
The Middle-Upper Proterozoic and Cambrian sediments are well developed in Yanliao Subsidence Belt of North China and the thickness of the sedimentary strata is almost 10 Km in which oil/gas shows are widespreaded. Based on the outcropped stratigraphic profile of the area, the oil generation conditio...

GEOCHEMICAL CHARACTERISTICS OF HYDROCARBONS GENERATED FROM COALS OF THE LONGTAN FORMATION, THE JURONG BASIN

1989, 11(1): 33-40. doi: 10.11781/sysydz198901033

Abstract(558) PDF-CN(271)

Abstract:
In order to approach the possibility and scale of hydrocarbon generation of the Longtan Formation of Upper Permian System in the Jurong Basin, the paper studied the maceral composition and geochemical characteristics of coals. The result shows the coal of the Longtan Formation is in the evolutionary...

APPROACHES ON THE OPTIMUM ORGANIZA TION OF THE GEOCHEMICAL EXPLORATIONS FOR PETROLEUM

Liu Congxi, Wang Huai

1989, 11(1): 41-49. doi: 10.11781/sysydz198901041

Abstract(565) PDF-CN(316)

Abstract:
In view of the limitations of the individual methods used in oil/gas geochemical explorations,the optimization of organization of the various methods would bring the advantages of the geochemical exploration into full play. The main methods of the geochemical exploration and the practices at home an...

TIANFU MOVEMENT-A SIGNIFICANT FACTOR OF PERMIAN-TRIASSIC GAS POOLS IN THE SICHUAN BASIN

Zhang Guanqun

1989, 11(1): 50-55. doi: 10.11781/sysydz198901050

Abstract(585) PDF-CN(287)

Abstract:
In the practices petroleum exploration in the Sichuan Basin, one would find that the Sichuan Movement can not be properly explained as a controlling factor on the formation of some structural traps. The author ot fhis paper reconstructs the ancient tectonics using the data of the sedimentation of Ma...

Diagenesis involves processes as follows. 1.transformation 2.replacement 3.compaction and pres...

DIFFERENTIAL SCANNING COLORIMETRY STUDIES ON KEROGEN

Wang Tingfen, Lu Shaoxin, Qin Kuangzong

1989, 11(1): 76-83. doi: 10.11781/sysydz198901076

Abstract(606) PDF-CN(312)

Abstract:
In order to study thermodegration of kerogen,the samples of kerogen in oil shales from Fushun,Maoming and Huang Xian and organic matter of brown coal from Huang Xian were investigated with differential scanning colorimetry(DSC) technique. The relations between the types of parent materials and oil-g...

LITHOLOGIC EFFECTS UPON THE STUDY OF CLAYSTONE COMPACTION USING THE DATA FROM TIME DIFFERENCE OF ACOUSTIC WAVE

Qin Ruozhe, Wang Zhongran

1989, 11(1): 84-90. doi: 10.11781/sysydz198901084

Abstract(697) PDF-CN(551)

Abstract:
Based on the lithological homogeneity of claystones, logging data of time difference of acoustic wave have been used to study the porosity and compaction of claystones. The claystones in the continental basins of Eastern China are often sand-bearing. The readings of time difference can be strongly a...
