高尚堡油田沙河街组三段二、三亚段为湖岸沉积体系，属扇三角洲沉积。扇三角洲由三个亚相组成，而构成其主体的则是扇三角前缘亚相，尤以近岸水下分流河道最为发育，为含油气性最好的砂体，远端席状砂次之。沉积相带与含油气性有较好的相关性，据此对区内断块进行评价预测，指出３０个有利含油相带，２８个较有利含油相带。
The second and third sub-sections of Shahejie Formation in Gaoshangpu Oilfield are lacustrine sedimentary systems and belong to fan delta deposition. The fan delta is composed of three subfacies, while the sub-facies that form the main part of the fan delta are the subfacies of fan delta front, especially the nearshore sub-distributary channel is the most developed and has the best oil and gas sand body. It Sedimentary facies belt has good correlation with oil and gas. Based on this, the fault blocks in the area are evaluated and predicted, and 30 favorable oil-bearing facies belts and 28 more favorable oil-bearing belts are pointed out.
