文南油田从东到西可分为 4个构造带 :文东滚动背斜带、文南地堑带、文西地垒带、文西斜坡带。在此基础上 ,引入“安德协森模式”和“板块构造理论”分析了文南油田形成机理 :文南油田是在东濮凹陷基底隆起背景上 ,经过后期拉张应力场的作用形成的 ,沉积物的重力作用在构造的形成过程中起到不可忽视的作用。在三者的共同作用下 ,形成了文南油田现今复杂的构造模式 ,形成了多种类型的油气藏
Wennan oilfield from east to west can be divided into four tectonic belts: Wendong rolling anticline, Wennan Graben zone, Wenxi basement belt, Wenxi slope zone. On this basis, the formation mechanism of Wennan Oilfield is analyzed by introducing “Andhra Pradesh Mode” and “tectonic plate tectonics theory”: Wennan Oilfield is formed by the effect of post-tensioning stress field on the uplift background of Dongpu Depression The gravitation of sediments plays an important role in the formation of tectonics. Under the joint action of the three, a complicated structural model has been formed in Wennan Oilfield, forming various types of oil and gas reservoirs
