对文留地区 4个构造带的地层、构造、生、储、盖及后期保存条件进行了研究 ,指出大断层和油源控制了构造带的油气分布 ,小断层只对构造带内的油气水分布起控制作用 ,而构造背景、沉积体系及生储盖配置关系决定了非构造油气藏的形成和分布。结果导致各构造带的油气富集程度相差悬殊 ,其中文留地堑带油气富集程度最高 ,文西地垒带、文东反向屋脊带次之 ,文西顺向屋脊带最差。指出文留地区滚动勘探潜力在于寻找“墙角”式断块油藏、深层油气藏、小断块油藏及岩性油气藏
The stratigraphy, tectonics, genesis, storage, cover and post-preservation conditions of the four tectonic belts in Wenliu area are studied. It is pointed out that large faults and oil sources control the distribution of oil and gas in the tectonic belts. Distribution of the control role, and the tectonic setting, sedimentary system and the relationship between reservoir and reservoir configuration determines the formation and distribution of non-structural reservoirs. As a result, oil and gas enrichment degree in each structural belt is quite different. The concentration of oil and gas in the Wenlei gravel belt is the highest, followed by the Wenxi base belt, the Wendong inverted roof ridge, and the Wenxi normal ridge roof. It is pointed out that the rolling exploration potential in Wenliu area lies in the search for “corner” type fault block reservoirs, deep reservoirs, small fault block reservoirs and lithologic reservoirs
