利用钻井、地质和地震等资料，通过构造发育史研究，认为本区构造特征为在东倾的斜坡背景上，东西分带、南北分区的区域构造格局；断层呈＂Ｓ＂形展布，同生小构造发育；自西向东可分为４个不同类型的圈闭带。结合本区已证实的含油层位，预测了相应油气藏的分布。
Using the data of drilling, geology and earthquakes, through the study of tectonic development history, it is considered that the tectonic features in this area are the regional tectonic pattern of east-west zoning and north-south zoning on the eastern slope background; Small tectonic development; from west to east can be divided into four different types of trap zone. Combined with the confirmed oil-bearing beds in this area, the distribution of the corresponding reservoirs is predicted.
