THE STUDY AND EXPLORATION OF THE MESO-CENOZOIC TECTONIC PROBLEMS IN EASTERN CHINA
LIN Zong-man
2015, 21(4): 453-462.
Abstract (210) HTML (89) PDF (1025KB)(31)
Abstract:
Based on the theory of geomechanics, the Meso-cenozoic tectonic characteristics and evolution in eastern China were concluded. This research shows that the history of the Meso-cenozoic deformation is divided into two stages in eastern China and the demarcation is the movement in Late Jurassic. There...
THE CLASTIC COMPOSITION CHARACTERISTICS OF UPPER PALAEOZOIC GLUTENITE IN NORTHEAST QAIDAM EDGE AND THE STRUCTURAL ATTRIBUTES OF SOURCE AREA

2015, 21(4): 463-472.
Abstract (263) HTML (95) PDF (1204KB)(15)
Abstract:
Combining the microscopic analysis of one hundred and twenty-six clastic rock samples from the Upper Paleozoic in Delingha region with the petrology and sedimentology features of Maoniushan formation, Chengqianggou formation, Huaitoutala formation, Keruk formation and Zhabugaxiu formation, we conclu...
RELATIONSHIP BETWEEN FAULT-ACTIVITY AND HYDROCARBON ACCUMULATION IN MINFENG FAULT ZONE OF DONGYING SAG
LI Hong-lin, JIANG You-lu, GUO Fu-xin, LU Zhi-yong, CUI Xiao-jun
2015, 21(4): 473-480.
Abstract (183) HTML (123) PDF (1034KB)(19)
Abstract:
Based on integration of 3D seismic, drilling and logging data and in combination with the history of hydrocarbon accumulation, we analyzed the features of faults activity by fault growth index and discussed the relationship between fault activity and hydrocarbon accumulation.The result shows that fa...
RESERVOIR-FORMING PATTERN OF THE SOUTH UPLIFT IN ENPING SAG
XIE Fei, WU Zhi-ping, YAN Shi-yong, HE Min, SONG Jia
2015, 21(4): 481-491.
Abstract (228) HTML (105) PDF (1131KB)(13)
Abstract:
The south uplift is the main hydrocarbon accumulation-forming zone of Enping sag. Using the basic data, we analyzed the conditions and characteristics of hydrocarbon accumulation in the south uplift and summarized the pattern of hydrocarbon accumulation. Hydrocarbon in the south uplift of Enping sag...
PALEO-PRESSURE RESTORATION AND DYNAMIC MECHANISM FOR HYDROCARBON MIGRATION AND ACCUMULATION OF Es3 MEMBER IN NORTH DONGPU SAG
ZHU Rong-wei, JIANG You-lu, LIU Jing-dong, HU Hong-jin, XU Juan-juan
2015, 21(4): 492-501.
Abstract (186) HTML (98) PDF (1257KB)(16)
Abstract:
With the application of fluid inclusions and basin simulation method, we restored the paleo-formation pressure of the third member of Shahejie formation (Es3) in North Dongpu sag, and analyzed the dynamic mechanism for hydrocarbon migration and accumulation. The results showed as follows:The formati...
DETERMINATION OF THE EARLY PALEOZOIC GRANITE IN ZHIFANG AREA, EAST JUNGGAR, XINJIANG AND ITS GEOLOGICAL IMPLICATIONS
XU Qin-qin, ZHAO Lei, NIU Bao-gui
2015, 21(4): 502-516.
Abstract (173) HTML (79) PDF (1349KB)(7)
Abstract:
Zhifang granite pluton outcrops in the northern part of Kalamaili tectonic belt, East Junggar Xinjiang. The latest strata intruded by the granite pluton are the Middle-Upper Ordovician Huangcaopo formation and it is unconformably covered by the Upper Silurian and Lower Devonian strata. Zircon SHRIMP...
STUDY ON FLUID INCLUSIONS AND GENETIC TYPE OF HAOYAOERHUDONG GOLD DEPOSIT, INNER MONGOLIA
WANG De-quan, WANG JIAN-GUO, WANG YI-ZHONG, LIU Jian-chao, ZHANG Hai-dong
2015, 21(4): 517-526.
Abstract (255) HTML (123) PDF (1066KB)(10)
Abstract:
The first and second members of Bilute formation are the major ore-bearing horizons in Haoyaoerhudong gold deposit. The rock types contain carbonaceous meta-siltstone, silty slate, carbonaceous slate and phyllite, etc. Au content is 7.14 times of the crustal abundance in the formation and the carbon...
COMPARATIVE ANALYSIS OF THE RETAINING WALL SEISMIC STABILITY OF NUCLEAR SAFETY RELATED SLOPE AND COMMON SLOPE
CHEN Li-wei
2015, 21(4): 527-535.
Abstract (223) HTML (67) PDF (891KB)(9)
Abstract:
Based on the theory of retaining wall stability calculation, the earthquake coefficient stated in Code for seismic design of nuclear power plants (GB 50267-97) was used. The calculation formulas of soil pressure and seismic angle for retaining wall of safety related slope were deduced and applied in...
IRON INFORMATION EXTRACTION IN LARSEMANN HILLS OF ANTARCTIC BASED ON WORLDVIEW-Ⅱ AND ASTER DATA
WEI Xue-juan, XU Gang
2015, 21(4): 536-545.
Abstract (190) HTML (106) PDF (1143KB)(12)
Abstract:
Combined with the Aster data of complementary bands, we studied the iron extraction information in Larsemann Hills at Antarctic continental margin using the WorldView-Ⅱ remote sensing images with high spatial and spectral resolution. The results show that it could achieve the complementary advantage...
STUDY ON ACID FRACTURE CONDUCTIVITY WITH LENGTH VARIATION IN CARBONATE RESERVOIR
WANG Yu-fang, DU Jian-jun, NIU Xin-nian
2015, 21(4): 546-554.
Abstract (232) HTML (98) PDF (1063KB)(18)
Abstract:
Based on the method of Nierode-Kruk theory, the change law between fracture conductivity and fracture length in different types of carbonate reservoir was obtained through fitting the change trend of the acid fracture conductivity with length variation, and the fracture-cave scale of the carbonate r...
