摘　　要：河岸地区位于东濮凹陷中央隆起带中部 ,区内油藏多为断块层状油藏 ,油气主要聚集在具有一定构造背景的局部构造上 ,沙一—沙二段各自呈现出不同的油气运移特征。通过对油气富集控制因素的分析 ,认为今后的滚动勘探重点仍然在沙一段和沙二下 亚段 ,围绕寻找构造高块和反向屋脊等圈闭 ,进一步扩大含油面积 ,拿到探明储量 ,同时也应拓宽区内勘探领域 ,加强沙三段油气成藏条件的研究 ,开辟新的油气滚动勘探战场。He'an area locates in the middle of central uplift belt in Dongpu deprssion,in the area,most oil pools are fault-block layered reservoirs,oil and gas mostly has accumulated in the trap which takes on a certain extent structural.In the area ,there are different hydrocarbon migration charaters from Es 1to Es 2.According to analysis of hydrocarbon accumulation factors ,it can be concluded that the center of future rolling exploration should be concentrated on Es 1and lower Es 2,with fastening on searching the top of structure,partial horst and inverse ridge fault-block,so as to ulteriorly enlarge area of reservoir and obtain proved reserves.At the same time ,the domain of exploration should be developed,and should be enhanced the research of reservoir forming condition of Es 3,so that a new exploration scope can be opened up.
