摘　　要：通过对柴达木盆地英东地区构造断裂特征、烃源岩条件、沉积储层的地层发育特征、生储盖组合等地质条件综合分析、评价认为:英东地区油砂山、英东一号构造等中浅层圈闭落实,油源充足且具有良好的生储盖组合。同时砂33、砂34井试油已获得油气流,说明油气层有东扩的趋势。因此通过目标优选评价认为该区具有良好的勘探前景,目前通过砂37、40井等井钻探已发现英东一号油气田。Based on an integrated analysis of such geological conditions as tectonic fracture characteristics, hydrocarbon source rocks, sedimentary reservoir strata and source-reservoir-cap rock in Yingdong area of Qaidam Basin, the authors have reached the conclusion that Yousha Hill and Yingdong No. 1 structure in the shallow traps of Yingdong area have adequate oil sources and possess ideal source-reservoir-cap rock assemblage. Test drilling of Sha-33 and Sha-34 wells has access to oil and gas flow, suggesting eastward expansion tendency of the oil and gas reservoir. Target optimization has revealed that the area has good prospects for exploration, and the drilling of Sha-37, Sha-40 wells has led to the discovery of Yingdong No. 1 oil and gas field.
