摘　　要：对文西地区地层、构造、生、储、盖及后期保存条件进行研究 ,指出该区含油层系较多 ,但主力层系突出 ;油气藏数量较多但规模较小 ,油气藏类型以小断块油气藏为主 ;文西地垒带油气富集程度高而文西顺向屋脊带油气富集程度低。并结合近几年的勘探实践说明 ,文西地区下步滚动勘探应以沙二下、沙三中层系为主 ,采用打“聪明井”进行多层兼探 ,着重寻找“墙角式”断块油藏、小断块油藏及岩性油气藏。An analysis on conditions of strata,fracture,source-reservoir-caprock and late preservation in Wenxi area,suggests that it has multiple oil-bearing system in this area,but dominant formation contradictory is prominent;oil and gas reservoir has a large quantity ,and its scope is small fault-block . Oil and gas enrichment de- gree is high in Wenxi horst and low in Wenxi consequent roofing area . Integrating on exploration practices in recent years,illustrate thatthe rolling exploration direction is focus on the blow of ES2 memberand the middle of ES3 mem- ber in the area,apply multi-layers exploration way by drilling' intelligentwell' .Itis focal point to seek the' wall footing style ' fault block ,small block reservoirs and lithologic reservoirs .
