THOUGHTS OF STRATEGIC HYDROCARBON SURVEY ON SUPERIMPOSED BASINS IN CHINA
ZHOU Xin-gui, LIU He-fu, WANG Zong-xiu, ZHANG Lin-yan, HUANG Chen-jun, LI Hui-jun, YAN Xi-li, MA Li-cheng
2011, 17(2): 111-120.
Abstract (225) HTML (114) PDF (571KB)(6)
Abstract:
During the 20th Century, most hydrocarbon reserves were found in Meso-Cenozoic continental rifts and foreland basins in China. While in the 21st Century, the increase points of reserves are transferring to Paleozoic marine carbonates in craton basins. The discoveries of Great Tahe Petroleum Field, a...
GEOLOGICAL CHARACTERISTICS AND EXISTING PROBLEMS OF LARGE GAS FIELDS FOUND RECENTLY IN CHINA
LI Hui-jun, ZHOU Xin-gui, ZHANG Lin-yan
2011, 17(2): 121-131.
Abstract (203) HTML (151) PDF (362KB)(8)
Abstract:
In the beginning of 21st century, natural gas exploration has been developing rapidly in China, with rapidly increasing of proven reserves and more and more newly found large gas fields, mainly located in 6 gas provinces, such as Ordos, Sichuan, Tarim, Qaidam, Songliao and Pearl River Mouth basins. ...
DRIVING EFFECT OF THE CRUSTAL STRESS ON PETROLEUM MIGRATION
WANG Lian-jie, SUN Bao-shan, WANG Wei, QIAO Zi-jiang, WANG Hong-cai, SUN Dong-sheng
2011, 17(2): 132-143.
Abstract (334) HTML (100) PDF (793KB)(26)
Abstract:
Oil and gas migration mechanics driven by the crustal stress and constitutional equation and flowing equation are discussed in this paper. Take the Dongying depression of Shengli oil field as an example, this study models the crustal stress and migration potential field at the central zone of the an...
POTENTIAL OF THE DEEP OIL-GAS RESERVIOR-FORMING AND EXPLOITATION DIRECTION IN JIZHONG DEPRESSION
ZHANG Lin-yan, FAN Kun, HUANG Chen-jun, MENG Qin-wei, LIU He-fu
2011, 17(2): 144-157.
Abstract (314) HTML (174) PDF (1237KB)(9)
Abstract:
The tectonic evolution and superimposing-transformation process of prototype basin are the basic conditions and controlling factors of hydrocarbon accumulation in deep layer of Jizhong depression. Effective hydrocarbon source rocks and preservation conditions of oil and gas are the two key factors f...
EVOLUTION OF PALEOZOIC SEDIMENTATION OF THE JUNGGAR BASIN
KANG Zhi-hong
2011, 17(2): 158-174.
Abstract (298) HTML (166) PDF (1636KB)(12)
Abstract:
Junggar basin, located at the northern part of Xinjiang, covers an area of 13 × 104 km2. To date, more than 30 oil and gas fields have been discovered. Many years'research shows that the basin has a pre-South China System crystallized metamorphosed basement. Under the control of Latitudinal and Xiyu...
EAST ASIAN MONSOON CHANGES DURING THE HOLOCENE———RECORDS FROM THE SOUTHEASTERN LOESS PLATEAU
XU Chen-xi, HAO Qing-zhen, YANG Shi-ling, ZHAO Shu-jun, ZHOU Xin, GE Jun-yi, XIAO Guo-qiao
2011, 17(2): 175-184.
Abstract (348) HTML (196) PDF (853KB)(20)
Abstract:
The influence of global warming on East Asian Monsoon (EAM) has received intensive concern, and studies on history of EAM could provide important climate analogue in the warmer temperature context.Five loess-paleosol sequences in the southeastern Loess Plateau were sampled to address the history of ...
RUN-THROUGH ALONG THE ESTUARY OF THE YALONG RIVER-JINGPINGZI REACH OF THE JINSHA RIVER
XU Qin-mian, YANG Da-yuan Yang, GE Zhaoshuai
2011, 17(2): 185-199.
Abstract (269) HTML (149) PDF (1587KB)(13)
Abstract:
Based on the study of the fluvial geomorphology along the Jinsha river from the estuary of Yalongjiang to Jinpingzi by using the methods of sedimentology, geomorphology and chronology, combining with the character of geomorphology and the Cenozoic sediment in this region, we suggest that the develop...
NUMERICAL SIMULATION OF THE STRAIN LOCALIZATION OF A CIRCULAR TUNNEL AT DIFFERENT ELASTIC MODULI
WANG Xue-bin, WANG Wei, PAN Yi-shan
2011, 17(2): 200-210.
Abstract (197) HTML (93) PDF (809KB)(6)
Abstract:
Strain localization processes of a circular tunnel at different elastic moduli are modeled by use of FLAC where the solution is based on equations of motion. In the present calculation, the tunnel is excavated after the model is loaded to reach a static equilibrium state. The numerical results show ...
