摘　　要：目的：探讨文南油田油气富集规律及滚动勘探开发。方法：在石油地质及构造地质特征基础上，结合近几年的勘探实际效果，对文南地区文88反向屋脊带、文南地堑带、文西地垒带及文西顺向屋脊带4个构造带的断裂、生、储、盖及后期保存条件进行了研究。结果：各构造带的油气富集程度相差悬殊，其中文南地堑带油气富集程度最高，文西地垒带、文88反向屋脊带次之，文西顺向屋脊带最差。结论：在文南油田应寻找“墙角”式断块，寻找深层气、小断块油藏及岩性油气藏。This paper describes the distribution characteristics of hydrocarbon enrichment and the pro-gressive exploration and development of Wennan Oilfield. Basing on the petroleum geoglogy and structural geolo-gy, and Combining with the actural results of exploration on the area, four structural belts: reverse roof ridge -like belt of Wen 88 block, graben belt of Wennan oilfield, horst belt and cisoid roof ridge - like helt of Wenxi oil-field, are studied for fracturing, produeing formation, reservoir and cap formation, and preservative conditions on later timc. Big differences of hydrocarbon enrichment are found among structural belt, so the area, which are to be developed in Wennan Oilfield, should be'marginal'fault, deep gas reservoir, small faulted reservoir and litho-logic hydrocarbon reservoir.
