At present, shale gas exploration in China has made a significant progress, and we have established four state- level shale gas demonstration areas that include the Fuling Jiaoshi dam, Changning--Weiyuan, Zhaotong and Yanchang. Shale gas production in last year has reached 13 ＊ 108m3, which the yield ofFuling Jiaoshi dam reached the highest 12.4 billion m3.

Spatial Distribution and Controlling Factors of Sedimentary Bodies in Jiaozhou Bay and Adjacent Sea Areas, Qingdao

引用

Journal of Ocean University of China 2011年第2期10卷 106-112页

作者： DONG Heping LI Guangxue LI shuanglin LI Shaoquan LI Chun college of Marine geoscienees Ocean University of China Qingdao 266100 P. R. China Key Laboratory of Hydrocarbon Resource and Environmental Geology Qingdao 266071 P. R. China Qingdao Institute of Marine Geology Qingdao 266071 P. R. China

The distributions of thickness of unconsolidated Quaternary sedimentary layers in Jiaozhou Bay and Qingdao offshore area were studied by using 1079-km high-resolution shallow seismic profiles and drilling core data, and the factors controlling the Quaternary evolution were discussed. The results show that such thickness distributions resulted from the coactions of geologic structures and marine hydrodynamic conditions since the Holocene. The geologic structures controlled the slope deposit, proluvial and fluvial fillings since the late Pleistocene. Holocene marine hydrodynamics eroded away sediments at the bay mouth, and tides carried these eroded materials to the sides of the bay mouth and released them there, forming channel-ridge-alternating geomorphic features. During transgressive processes, the sea level rose rapidly, and insufficient sediment supply and tidal actions yielded the relict sediments in the east of Qingdao offshore area.
