THE OIL-GAS EXPLORATION DIRECTION OF FUXIN BASIN

With nearly thirty years of oil-gas exploration activities, there has been no significant discoveries in Fuxin Basin. In order to further evaluate its resources potential and make new exploration ideas, based on the comprehensive study on petroleum geological condition and major controlling factors of hydrocarbon accumulation, the authors consider that the Fuxin Basin has the general conditions for conventional and unconventional oil-gas accumulation and the main exploration layers are Jiufotang, Shahai and Fuxin formations. According to the difference of hydrocarbon source rock condition among them, the upper Jiufotang and lower Shahai formations are conventional oil and gas exploration targets, the upper Shahai formation shale as gas exploration target and the Fuxin formation as coal bed methane exploration target. The hydrocarbon accumulation condition analysis indicates that the main controlling factors of hydrocarbon reservoir in Fuxin Basin are preservation and reservoir condition. The direction for oil-gas exploration in the area is searching for structural-lithologic and lithologic reservoir near sag.
