BASIN TYPES AND CHARACTERISTICS OF BASIN GROUPS IN EAST ASIA
KANG Yong-shang, SHANG Yue-nan, YUE Lai-qun, DIAO Shun, QI Xue-feng
2012, 18(4): 347-358.
Abstract (418) HTML (218) PDF (2295KB)(17)
Abstract:
Tectonic evolution in East Asia was polyphased and complicated. The geological framework of East Asia basically formed during Indo-Chinese epoch. As an important tectonic evolution stage, Yanshannian epoch played a significant role in the evolution and formation process of sedimerntary basins in Eas...
A DEMANDING DEVELOPMENT TO HYDROCARBON RESOURCES IN CHUXIONG BASIN
LIN Zong-man
2012, 18(4): 359-378.
Abstract (674) HTML (453) PDF (4905KB)(15)
Abstract:
Mesozoic and Paleozoic marine hydrocarbon resources have been developed in South China except Sichuan Basin for half a century. The Chuxiong Basin is very important in oil and gas exploration in South China because of its material basis and favorable tectonic environment forming large-and-middle sca...
DEPOSITIONAL FILLING MODEL AND EVOLUTION OF THE SAG IN LACUSTRINE BASIN:A CASE STUDY FROM SHAHEJIE FORMATION IN MAXI SAG, RAOYANG DEPRESSION
ZHANG Yi-ming, LI Sheng-li, LI Min, YU Xing-he, ZHANG Wan-fu, TIAN Qian-qian, FANG Xin-xin
2012, 18(4): 379-388.
Abstract (202) HTML (127) PDF (1751KB)(5)
Abstract:
Sag is an important part of the rift lacustrine basin and is the main occurrence area of hydrocarbon source rocks. But in terms of its unique characteristics of sedimentary filling, the buried depth and the reservoir development, the exploratory degree of petroleum in a sag is usually low. Maxi sag ...
THE WALL ROCK ALTERATION AND ITS GEOCHEMICAL CHARACTERISTICS OF THE SHAZHOU DEPOSIT IN XIANGSHAN URANIUM ORE-FIELD
CAO Xiao-bing, LÜ Gu-xian, HU Bao-qun, ZHENG Guang-gao, YAO Hong-xin, LIANG Dong
2012, 18(4): 389-400.
Abstract (240) HTML (74) PDF (2470KB)(15)
Abstract:
The ore body of Shazhou deposit in Jiangxi Province is strictly controlled by faults and its wall rock alteration zoning characteristics is very apparent. This paper introduces the geochemical characteristics of the wall rock alteration. The results of whole-rock analysis of Shazhou deposit show tha...
CHARACTERISTICS AND SIGNIFICANCE OF THE COPPER-GOLD-ANTIMONY DEPOSITS IN DAGANGOU AREA, EAST KUNLUN
ZHANG Kai, GOU Rong-tao, LIU Shu-lin, GUO Gang, XU Jun-jie, WANG Bo-wen, LI Hua-nan, YUAN Jing
2012, 18(4): 401-409.
Abstract (218) HTML (158) PDF (2905KB)(8)
Abstract:
The East Kunlun area is located at the suture zone of Sino-Korean Plate, Tarim-Qaidam Plate, Yangtze Plate and India Plate. The special tectonic structural location decided its tectonic evolution being very complicated and distinctive. The geochemical anomalies in this area composed by Au-Co-Cu-Pb-Z...
GENESIS OF NODULAR LIMESTONE IN THE UPPER CAMBRIAN BAOSHAN FORMATION IN WESTERN YUNNAN PROVINCE
HAO Jia-xu, PENG Cheng-long, ZHANG Guo-xiang
2012, 18(4): 410-417.
Abstract (467) HTML (234) PDF (1771KB)(18)
Abstract:
In this paper, the depositional environment and formation mechanism of the nodular limestone from the Under Cambrian Baoshan Formation in Shidian region, western Yunnan Province was discussed on the basis of mineral components, texture and structure of the node and matrix. Researches show that there...
ROCK MECHANICS PARAMETER CALCULATION BASED ON CONVENTIONAL LOGGING DATA:A CASE STUDY OF UPPER PALEOZOIC IN ORDOS BASIN
GUI Rong, WAN Yong-ping
2012, 18(4): 418-424.
Abstract (682) HTML (147) PDF (1324KB)(95)
Abstract:
As the rock mechanics parameters such as Young modulus and Poisson ration are the basic data for drilling and completion as well as design for reservoir fracturing in oil field, and for simulation of tectonic stress field in sedimentary basin, it is the key contents that obtain rock mechanic paramet...
A FEASIBILITY STUDY ON TT-OSL DATING FOR THE EOLIAN SEDIMENTS FROM NORTHERN SLOPE OF KUNLUN MOUNTAINS, XINJIANG
ZHANG Ke-qi
2012, 18(4): 425-432.
Abstract (218) HTML (99) PDF (1136KB)(5)
Abstract:
The feasibility of TT-OSL dating for the eolian sediments at northern slope of Kunlun Mountains was discussed in this paper. The four samples were collected in Keriya River to Pishan County, southern Xinjiang. The measurement results showed that the intensity of TT-OSL signals were very weak, which ...
ANALYSIS ON OPEN HOLE STABILITY OF A DEEP GAS WELL WITH HIGH PRESSURE DURING TESTING
CHEN Jun-hai, CHEN Mian, JIN Yan
2012, 18(4): 433-439.
Abstract (201) HTML (101) PDF (712KB)(12)
Abstract:
During testing of the open hole of high pressure and deep gas well, borehole collapse may occur in open-hole sections, because borehole fluid pressure was too low to support the borehole wall. Based on stress distribution near wellbore area under non-uniform tectonic stresses, seepage stress field c...
NUMERICAL SIMULATION OF LANDSLIDE MECHANISM AT ERMANSHAN IN HANYUAN UNDER DIFFERENT CONDITIONS
TAO Qian, LIU Chao, ZHU Zhi-ming, YANG Yong, ZOU Zuyin
2012, 18(4): 440-450.
Abstract (264) HTML (96) PDF (2388KB)(5)
Abstract:
In this paper, the FLAC3D software was used to establish the model of Ermanshan Mountain in Hanyuan County, Ya'an City, Sichuan Province and to simulate the rainfall landslide process. The stress-strain features and slope stability were calculated and analysed in order to offer a reliable basis for ...
