QUANTITATIVE CHARACTERIZATION OF MECHANICAL PROPERTIES OF DEFORMATIONAL ZONES
ZHENG Ya-dong
2005, 11(3): 197-203.
Abstract (232) PDF (333KB)(18)
Abstract:
The determination of mechanical properties of a deformation zone is the first step in the geomechanical study.Some new concepts and methods have been proposed and can be used for quantitative characterization of mechanical properties of deformation zones.Natural deformational zones are commonly the ...
SIMULATION STUDY OF THE LITHOSPHERIC THINNING IN EASTERN CHINA AND DYNAMIC MECHANISM OF SYNCHRONOUS BASIN-MOUNTAIN COUPLING
WU Hong-ling, YIN Xiu-lan
2005, 11(3): 204-214.
Abstract (187) PDF (532KB)(12)
Abstract:
A geomechanical model for the evolutionary process of lithospheric thinning in eastern China is constructed in light of the geological fact that significant changes took place in Cenozoic tectonics and geomorphology on the continent of China.Assuming that the various layers of the lithosphere are ma...
QUANTITATIVE PREDICTION OF THE DISTRIBUTION OF TECTONIC FRACTURES RELATED TO FLEXURAL DEFORMATION IN UPPER PALEOZOIC TIGHT SAND RESERVOIRS IN THE TABAMIAO AREA, NORTHERN ORDOS BASIN
ZHOU Xin-gui, ZHANG Lin-yan
2005, 11(3): 215-225.
Abstract (190) PDF (777KB)(7)
Abstract:
The Tabamiao area is located in the Yishaan slope tectonic belt in the north of the Ordos basin.The structure is gentle and it is commonly thought that there are no conditions for fracture growth.However,many regional tectonic fractures in upper Paleozoic reservoirs and local tectonic fractures rela...
PREDICTION OF GAS POTENTIALS OF SAND RESERVOIRS OF THE LOWER SHIHEZI FORMATION IN THE TABAMIAO AREA, ORDOS BASIN
WU Li, SHI Wei, DONG Ning, ZHOU Xiao-ying, YU Wen-qin, MA Dian-ren, WEI Wei
2005, 11(3): 226-234.
Abstract (247) PDF (944KB)(9)
Abstract:
A set of techniques of prediction of 3D sand reservoirs suitable to the geological characteristics of the Lower Shihezi Formation in the Tabamiao area,Ordos basin,has been preliminarily established according to the key and difficult points of prediction in the area,combined with its geological and g...
A METHOD FOR EVALUATING THE PRODUCTION POTENTIAL OF RESERVOIRS IN THE SHILONGCHANG-BAIYA OILFIELD IN NORTHERN SICHUAN AND ITS APPLICATION
YAN Bin, SHU Neng-yi, YANG Lei, XU Jing
2005, 11(3): 235-244.
Abstract (263) PDF (392KB)(9)
Abstract:
The Silongchang-Baiya oilfield,located in the northern Sichuan basin,is an oilfield that was put into production earliest by Southwest Subsidiary Company of SINOPEC.Geological conditions of the oilfield are so complicated that exploration and exploitation are very risky.Up to now,31 wells have been ...
SEDIMENTARY SYSTEM OF “FOUR FANS AND ONE CHANNEL” IN THE BOHAI GULF BASIN AND ITS SIGNIFICANCE FOR PETROLEUM EXPLORATION
ZHAO Guo-lian, ZHA Chen-lin, YE Lian-jun
2005, 11(3): 245-258.
Abstract (229) PDF (917KB)(10)
Abstract:
This paper discusses the characteristics and distribution of sedimentary facies favorable for petroleum accumulation in Paleogene strata in the Bohai Gulf and its surroundings and their control on petroleum distribution.The sedimentary facies are obviously affected by structure.The understanding of ...
STRUCTURAL SYSTEM AND HYDROCARBON DISTRIBUTION IN THE BOHAI GULF BASIN
XU Shou-yu, YAN Ke
2005, 11(3): 259-265.
Abstract (367) PDF (480KB)(17)
Abstract:
The Bohai Gulf basin is an important hydrocarbon base of China.In the basin many types of structural systems such as en-echelon and brush structural systems are developed and show a complex spatial distribution.The hydrocarbon accumulation and occurrence in the basin are controlled by different orde...
ANALYSIS OF KINEMATIC FEATURES OF THE GANJIANG FAULT ZONE BASED ON THE TECTONIC EVOLUTION OF THE NANCHANG SUBBASIN
ZHOU Song-yuan, ZHANG Jie-hui, XU Ke-ding, JIANG Wei-shan, PEN Jun, LIU Jia-duo
2005, 11(3): 266-272.
Abstract (307) PDF (571KB)(8)
Abstract:
On the basis of an analysis of geological and geophysical data obtained by petroleum exploration in the South Poyang depression in recent years,the authors propose that the basining and tectonic evolution of the South Poyang depression were controlled by the activities of the Ganjiang fault zone und...
NUMERICAL MODEL OF FULLY COUPLED FLUID-SOLID SEEPAGE IN A DEFORMABLE POROUS MEDIUM AND ITS APPLICATIONS
DONG Ping-chuan
2005, 11(3): 273-277.
Abstract (229) PDF (217KB)(10)
Abstract:
The effective stress in the rock matrix of a reservoir increases as a result of the decline in pore fluid pressure with the continuous withdrawal of subsurface fluids.Under such conditions,more load is transferred to the rock matrix,and thus the rock is compacted or deformed,which can sometimes prod...
APPLICATION OF THE ULTRASONIC FLAWLESS DETECTOR IN THE PRESERVATION OF UNEARTHED STONY CULTURAL RELICS
ZHANG Zhi-guo, PENG Hua, MA Yin-sheng, BAI Jia-qi, MA Xiu-min
2005, 11(3): 278-285,244.
Abstract (184) PDF (744KB)(9)
Abstract:
Taking for example the flawless detection of the imperial tablet of the reign of Emperor Qian Long of the Qing Dynasty unearthed recently for its protection and restoration,the paper introduces a new method of detecting quantitatively fractures and weathering degrees inside stony cultural relics wit...
STUDY OF DEFORMATION AND FAILURE OF ROCK BASED ON PROPERTIES OF COHESION AND FRICTION
YOU Ming-qing
2005, 11(3): 286-292,258.
Abstract (262) PDF (558KB)(13)
Abstract:
In terms of microscopic textures,mineral particles are either cohesive or separated,and the cohesive force and internal frictional force of the Coulomb criterion cannot exit together locally.Cracks are produced and increase gradually with deformation,and the cohesion between particles in material lo...
