摘　　要：孤南洼陷东部地区上第三系具有特殊的油气成藏特征,且油气资源丰富。文章剖析了该地区的成藏基本条 件、油藏发育类型以及成藏控制因素,认为该类地区主要发育与岩性相关的断层-岩性油藏和构造-岩性油藏;油 气成藏主要受断裂活动和油气疏导体系的控制。油气以网毯式运聚成藏,油气从毯式仓储层运移进入网式储集层 后,主要在构造脊内运移,遇到合适的圈闭聚集成藏。Abundant petroleum resource appeared in the Neogene system in the east of Cunan subsag which had special characteristics of hydrocarbon reservoir forming. According to the analysis of the basic conditions, the controlling factors of the reservoir forming and the type of reservoir, it is considered that fault - lithologic and structural-lithologic reservoirs related to the lithology developed in the region; the reservoir forming was controlled by the fault activity and hydrocarbon transloca- tion system. The pattern of the migration, accumulation and pool-forming is meshwork carpet type. After migration from the carpet reservoirs into the meshwork reservoirs, the hydrocarbon migrated in the ridge of the structure mainly, then formed reservoir when meeting suitable traps.
