摘要
东濮凹陷东南部是一个断裂构造复杂、沉积体系类型多样、具典型箕状盆地结构的油气富集区,油气分布明显受断裂构造和岩相类型的控制.根据研究区油气藏形成的主导因素,可确定出反向屋脊断块油气藏、逆牵引油气藏等九种油气藏类型,它们具有各自的展布特征和含油气性.特别是在中央隆起带,油气藏类型丰富、油气分布层系多、含油气面积大,从而构成了具有油气勘探和开发前景的复式油气聚集带.
The southeast part of the Dongpu depression is an area of accumulation, which is characterized by complex fault associations, various types of depositional systems and typical basin structure of dust-pan shape. Oil/gas occurrence is controlled by fault activities and lithofacies types. In the light of the major controlling factors of pool formation, 9 types of pools which possess specific distribution features and oil-bearing strata are identified. A number of oil/gas pools and a large oil-bearing area constitute a complex hydrocarbon accumulation belt favorable for oil-gas exploration and development.
