文西断裂带油气成藏条件研究

文西断裂带位于东濮凹陷中央隆起带的西部，构造面积约80km^2，主要断裂北东向展布，西部紧邻海通集生油洼陷，具有良好的油气成藏条件。通过对文西地区烃源岩及其演化、储盖组合、油气运移和断层封闭特征等油气成藏条件的分析，阐明该区油气藏形成的主要控制因素、油藏类型及油气分布规律，为该区勘探开发提供地质依据。

Study on Formation Conditions of Oil Reservoirs in West Wenliu Fault-zone

West Wenliu fault-zone lies in the west part of Wennan oil field which is located on middle uplift zone of Dongpu Depression.Its structural area is about 80km 2 and the main faults distribute along northeast.The west is bordered upon generating depression of Haitongji which has a good condition of reservoir formation.According to the analysis of the source rock and source rock evolution,source-reservoir-cap rock association,the migration of oil and gas and the sealing characters of faults,this paper illustrates the main controlling factor of reservoir formation,the styles of reservoir and the distributional law of oil and gas,and provides the geological bases for the exploration and development of gas and oil.
