     The thickness of shale reservoir for Lower Cretaceous l,ishugou Formation in eastern area of Liaohe is great, with wide and stable distribution. TOC of shale is high and degree of thermal evolution is moderate. The kerogens are mainly Type Ⅱ, mainly by gas generation with great intensity of hydrocarbon generation, having the basic condition of shale enrichment. The pore types of shale are mainly residual intergranular pores, microporous pores and solution pores. The porosity and permeability are good. The content of brittle minerals such as quartz and feldspar is high, which is beneficial to shale gas storage and later reservoir stimulation. Its geologic and geochemical characteristics are similar to Triassic shale in Yanchang oilfield, in which continental facies shale gas has been found. The enrichment potential of shale gas is great. Using the method of superposition for comprehensive information, this paper preliminarily predicts the favorable area of Lower Cretaceous Lishugou Formation shale gas enrichment. It is considered that the favorable area is mainly distributed as a belt-shaped region along Yingkou-Tongerpu.
