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。
The riparian area is located in the middle of the central uplift belt of Dongpu depression. Most of the reservoirs in this area are fault-block layered reservoirs, and the oil and gas mainly accumulate on the local structures with certain tectonic setting. The second member of Shahejie Formation shows different oil and gas transport Move Features. Based on the analysis of controlling factors of oil and gas accumulation, we think that the focus of rolling exploration in the future is still in the first section of Shahe and Sha2, and focus on the trapping of tectonic blocks and inverted roofs to further expand oil area, At the same time, we should also broaden the exploration area in the area, strengthen the research on hydrocarbon accumulation conditions in the third member of Shahejie formation, and open up a new exploration battlefield for oil and gas rolling.
