摘要: 文23断块是东濮凹陷中央隆起带文留构造北部一个地垒型断块。沙四气藏为一南倾的鼻状构造。断块的形成是先后受近东西向拉张东推应力作用和右旋平移应力复合作用结果,形成现今的被断层分割的地垒块构造格局。文东,文西两组断层既是该断块东、北、西边界,又控制着断块区內气水分布。

Abstract: Wen-23 fault block is a horst fault block in the middle and north parts of wenliu structure in the central swell of Dongpu Depression. Sha-4 gas reservoir is an inclined nose-like structure in the south. The fault block results from the pull from the near east to the west and the thrust to the east as well as the right spin and translation compound stress, thus forming the existing horst structure pattern broken up by faults. wendong and wenxi faults not only are the boundaries of the east, the north and the west,but also control the distribution of gas and water in the fault block.

Key words: Fault block, Structure, Evolution, Distribution of oily gas and water
