| 摘 要： | 为了指导下一步天然气藏的勘探，详细分析了工区内影响天然气成藏的生、储、盖条件，总结出民丰、胜坨、利津地区不同的天然气成藏模式。研究表明，东营北带深层烃源岩主要为盐下的暗色泥岩，其储集空间主要为湖盆周围呈扇状分布的砂砾岩体内的次生孔隙和裂缝，利津地区沙四下以气为主，胜坨地区沙四下以较高气油比的油为主，民丰地区沙四下盐上以油为主，盐下以气为主。

| Abstract: | Since 2004,great breakthrough has been obtained in the exploration of deep strata underlying gypsolith of northern Dongying Sag. For the future natural gas exploration in the area,an integrated analysis of the conditions of source rock,reservoir rock,and cap rock was carried out,and summarized the natural gas pool forming modes of deep strata in Mingfeng,Shengtuo and Lijin area.Studies show that the source rock of deep strata is dark mudstone under gypsolith,in which the main reservoir space is the secondar... |
