West Sag of Liaohe Depression is a representative hydrocarbon-rich sag in eastern China, with a high degree of exploration. The deep stratigraphic-lithologic reservoirs are the main exploration targets in the further exploration of West Sag, and the lithologic reservoirs are considered tomainly distribute in the third member of Shahejie Formation. It is believed that lithologic reservoirs are mainly controlled by three factors, including effective source rocks, turbidite sand body distribution and hydrocarbon migration. Based on the analysis of petroleum accumulation factors, the favorable zones of the lithologic reservoirs of the third member of Shahejie Formation are predicted, and the most favorable zone is in Qingshui sub-sag ofWest Sag and the surrounding areas.
