摘　　要：分析文北地区的地层、构造、生储盖及后期的油气保存条件 ,总结了该区油气富集规律。结合近几年的勘探开发实践 ,认为文西地区北部下步滚动勘探应以沙二下亚段、沙三中亚段层系为主 ,采用定向井技术 ,进行多层兼探 ,着重寻找“墙角”式断块油藏及隐蔽岩性油气藏。The stratum, conformation, oil formation and storage cover and the oil-gas preservation condition in Wenbei District were analyzed, and so was the congregation law of oil-gas in this area summarized. Based on the findings got from prospecting practices in recent years, the authors thought that the next prospecting in the lower part of Wenbei District in Wenxi should focus on the sub-second layer of Sha-er and the mid-second layer of Sha-san. Directional-well technology should be used to do multi-layer prospecting, whose stress should be laid on finding the 'wall-corner' fault block oil reservoir and the covert lithology oil-gas reservoir.
