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。
The stratigraphic, structural, genesis, reservoir, cover and post-preservation conditions in Wenxi area are studied. It is pointed out that there are many oil-bearing strata in this area, but the main strata are prominent. The reservoirs with large and small number of reservoirs and small reservoirs Fault block reservoirs; Wenxi basement with a high degree of oil and gas enrichment Wenxizhixiang ridge Ridge with low degree of hydrocarbon accumulation. In combination with the exploration practice in recent years, the rolling exploration in the Wenxi area should be dominated by the second and third middle sand strata. The multi-layer exploration using “smart well” should focus on finding the “corner” fault block Reservoirs, small fault blocks and lithologic reservoirs.
