摘要
岩性油气藏已成为牛庄洼陷油气勘探重点,洼陷内沙河街组发育大量厚层烃源岩,为圈闭成藏提供了充足的油气资源。勘探证实,洼陷内发育三角洲前缘滑塌浊积、深水浊积扇等砂体类型,同时发育断裂型、砂体型、不整合面型等多种输导体系和良好的泥岩盖层,生、储、盖条件在时间、空间上具有良好的组合关系,为形成岩性油气藏和构造-岩性油气藏提供了良好条件。
Lithologic reservoir has been a focal point of exploration in Niuzhuang lowland,where a great amount of thick source rocks had developed in Shahejie formation,which provided abundant oil and gas resources for accumulation.Exploration proved that in the lowland,sands like delta front slump turbidite and deep water turbidite fan had developed;also developed were transportation systems including fracture,sand and unconformable surface,as well as good mudstone cap rock;there was a good association of source-reservoir-caprock in time and space,providing good conditions for forming lithologic reservoir and structural-lithologic reservoir.
