摘　　要：针对宝饶复式油气藏复杂的构造及油气水分布规律 ,开展了该油气藏沉积、构造、生储盖条件及其组合关系等研究 ,认为宝饶构造带沉积储层与油气运移、构造圈闭匹配关系良好 ,具备良好的成藏条件 ,是吉尔嘎郎图凹陷油气富集最为有利的构造带 ,其中 K1bt2 是油气最富集的层位 ;进一步探讨了宝饶复式油气藏油气分布规律及影响因素、油气藏类型 ,认识到其油气分布主要受沉积微相及断层封挡作用的影响 ,构造及岩相的复杂性导致了油气藏的多样性。据此指导油田的滚动勘探开发 ,实现了宝饶构造带含油连片 ,确保了油田高的滚动勘探开发综合效益 。A comprehensive study of the sedimentary structure, source reservoir cap conditions, and their assemblage connection of the Baorao complex reservoir indicates that the matching relation between the sedimentary reservoir, oil gas migration, and structural trap of the Baorao structure zone is all right, that it possesses better oil and gas accumulation formation conditions, and that it is the most advantageous structure zone in Jiergalangtu depression, and the K 1 bt 2 is the most enrichment layer. A farther study of the oil and gas distribution rule, effective factors, and reservoir type of the Baorao complex reservoir indicates that the oil and gas distribution rule is affected by the sedimentary microfacies and fault block action. The complexity of the structure and lithofacies results in the multiformity of the reservoir. This guides the progressive petroleum exploration and development and ensures a comprehensive, efficient progressive exploration and development. This provides a direction for the study of farther progressive evaluation.
