摘要
Shenxian Depression is located in the center part of Jizhong sub-basin, North China, with extremely complicated structures and diverse sedimentation systems. There are many different recoganizations of the classification of hydrocarbon traps and their distribution in the past years, which has restricted the accurate hydrocarbon exploration in such kind of complicated faulted depressions. Lithologic and stratigraphic traps mainly existed in two flanks of buried hill zone and Shennan anticline and Baisongzhuang trough in the south, which responded to lenticular sandy conglomerate, updip sand body and tectonic setting in these areas. Therefore, it can be concluded that structural-stratigraphic composite petroleum reservoirs should be more important in the future hydrocarbon exploration in Shenxian Depression.
