Based on the comprehensive analysis of drilling, well logging, seismic and testing data, the distribution of depositional systems were established to pinpoint the characteristics of source-reservoir-cap and analyze the primary factors controlling hydrocarbon accumulation in Shuangliao Fault Depression, and then the favorable exploration play was predicted. The results indicate that semi-deep lacustrine-fan delta-neritic subaqueous fan sedimentary system was developed in the Shahezi Formation, forming upper source-lower reservoir type of source-reservoir-cap assemblage combined with the volcanic rocks of Huoshiling Formation. The primary factors controlling hydrocarbon accumulation of Shuangliao Fault Depression include volcanic doom structure, favorable supply of oil and gas, well-developed reservoirs in the volcanic doom structures, favorable assemblage of source-reservoir-cap and space-time configuration of accumulation factors. The volcanic doom structures of Sangshutai Bulge are the favorable target areas of oil and gas exploration in the future.
