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 ,并为油田进一步滚动评价指明了方向
In view of the complicated structure and hydrocarbon-water distribution of the Baorao multi-type reservoir, the study on sedimentary, tectonic, reservoir-cap conditions and their combination relations of the reservoirs has been carried out. It is concluded that the sedimentary reservoirs and hydrocarbon migration, Close matching is good, with good reservoir forming conditions, which is the most favorable structural belt for oil and gas accumulation in the Jilgarnglang depression, where K1bt2 is the most abundant oil and gas layer; and further discusses the oil and gas distribution rules and Influencing factors and types of oil and gas reservoirs. It is recognized that the distribution of oil and gas is mainly affected by sedimentary microfacies and fault sealing, and the complexity of structure and lithofacies has led to the diversity of reservoirs. Based on this, we can guide the rolling exploration and development of the oilfield and realize the oil-bearing contiguous section of Baogao structural belt, ensuring the comprehensive benefits of high rolling exploration and development in oilfields and pointing out the direction for further rolling evaluation of oilfields
