POLICY, WAY OF THINKING AND AREA SELECTION

Sun Zhaocai

1989, 11(4): 301-313. doi: 10.11781/sysydz198904301

Abstract(493) PDF-CN(298)

Abstract:
The reason that the productivity and reserves of natural gas fall behind may not be attributed to "more stress on oil than gas" in our work,rather. It is important to encourage the policy of energy resources with emphasis on exploration; and to establish "four new concepts" (new way of thinking, new...

Abstract(775) PDF-CN(329)

Abstract:
Back thrust block structures reffered to two or more serieses of back thrust faults with opposite inclination in space and in-between blocks, which were dominant in the deformational forms in the vast area of northern part of Tarim basin. Six major structural belts of back thrust blocks were determi...

ON THE LOW VELOCITY LAYER AND CONRAD SURFACE WITHIN THE CRUST OF SOUTHERN PARTS OF CHINA

Abstract(640) PDF-CN(374)

Abstract:
Analogies are drawn between the models of crustal structure and velocity distribution on the basis of explosion seismological data of the southern parts of China. Further, the distributions of low velocity layer and Conrad surface (or Conrad discontinuity) within the crust, which are relative to the...

ON THE ORIGIN, DISTRIBUTIVE PATTERN AND TECTONIC CONTROL OF SILICEOUS ROCKS IN GUFENG AND DALONG FORMATIONS, SOUTH CHINA

Abstract(947) PDF-CN(493)

Abstract:
The paper discussed about the time and space, distributive pattern and sedimentary characteristics of the radiolarian siliceous rocks in Permian Gufeng and Dalong Formations of south China massif. The accumulation of the siliceous rocks is the result of the convection of hot and cold sea water in th...

CHARACTERISTICS OF SEDIMENTARY DIAGENESIS FOR RESERVOIR ROCKS OF VOLCANIC CONGLOMERATES IN URHO FORMATION AND RELATIONSHIP WITH HYDROCARBON ACCUMULATION

Abstract(598) PDF-CN(247)

Abstract:
With the discussion on the characteristics of sedimentary diagenesis for conglomerates of peidmont diluvial fan facies on the dry basin margin, the inner relations of the resolution, solution and porosity evolution of authi-genic zeolites with hydrocarbon accumulation in sandstone enriched in volcan...

FAVOURABLE REGION AND CONDITIONS FOR PETROLEUM EXPLORATION OF LOWER PALAEOZOIC IN LESHAN-LONGNUSI PALAEO-UPLIFT AREA

Zhao Xikui

1989, 11(4): 361-368. doi: 10.11781/sysydz198904361

Abstract(628) PDF-CN(342)

Abstract:
With synthetic studies of informations of geology, geophysics and dri-lling, the author thought that Leshan-Longnusi uplift was influenced by several tectonic movements during Caledonian period and was controlled by border faults. It experienced erosion at the end of Guangxi movement, thus became fi...

STUDY ON BURIAL HISTORY OF THE STRATA IN JIANGHAN BASIN

Luo Xiaorong, Chen Heli, Wang Jiahua, Wang Fengqin

1989, 11(4): 369-378. doi: 10.11781/sysydz198904369

Abstract(735) PDF-CN(355)

Abstract:
The compaction model suitable for Jianghan Basin was established, and different compactive correcting formala were chosen for different types of rocks. Furthermore, the erosional thickness of the strata in the end of late Tertiary was restored with the conversional relation of acoustic time and poro...

A QUEST FOR A NEW PARAMETER IN PETROLEUM EXPLORATION GEOCHEMISTRY

J. W. Smith, T. D. Gilbert, B. D. Batts

1989, 11(4): 379-389. doi: 10.11781/sysydz198904379

Abstract(697) PDF-CN(309)

Abstract:
Primary Australian terreestrially-derived crudes are characterised by high wax and n-alkane contents.These characteristics, as determined by hydrogenation and hydrous pyrolysis, appear to be unrelated to either the chemical or petrographic compositions of Victorian brown coal lithotypes. Furthermore...

MEASUREMENT OF RESIDUAL HYDROCARBON C₅—C₃₅ IN ROCKS WITH THE METHOD OF COLLECTION ON CAPILLARY COLUMN

Wu Jie, Zhang Yijia

1989, 11(4): 390-393. doi: 10.11781/sysydz198904390

Abstract(640) PDF-CN(213)

Abstract:
In the study, the new technique of hydrocarbon condensation on capillary column was mainly applied, with the quartz inner tube of the injector in chromatographic analyser as sample tube. Residual hydrocarbon C₅-C₃₅ in rock samples were expelled by carrier gas in pneumatolytic chamber at controlled t...

This paper is to analyze multiaspects and multiseries in petroleum accessment, and to study the undeterministic knowledge and qualitative laws used by petroleum geologists and to conclude that there is the potential information loses in the processes of thinking and description. It is important to m...

ORDERED COLONY OF FOSSIL SPORE-POLLEN

Tong Guobang, Lin Jinxuan, Chen Zuyin
