摘要 通过对川口地区长6油层组的划分与对比,结合特征的岩相组合、骨架砂体的几何形态、盆地古地理背景的综合分析,以及储层的岩性特征和孔隙结构的研究,认为长6油层组的环境演化代表了浅水台地型三角洲逐渐转变为陆上平原的历史;曲流河道砂体是区内油气富集的有利相带;长61段和长62段是主力油层。 According to synthetical analyses of the division and contract of the Chang-6 oil-bearing bed and of the characteristic factes association, geometry of the skeletal sandbodies and the paleogeographic pattern, the evolution of the environment during deposition of Chang-6 oil-bearing beds is considered representing the history that the water platform delte was gradually transformed into terrestrial plain. The meander channel sandbodies are the major factes-oil-bearing in this area. The Chang-61 and the Chang-62 members are the major reservoivs in chuankou area.
