| 摘 要： | 以前的研究一直认为鄂尔多斯盆地陕北斜坡东部延长组油藏仅受到沉积相的控制,其圈闭类型为岩性圈闭。但笔者经过研究发现,陕北斜坡中川区长6油层组油藏并不仅仅受到沉积相带的控制,而是受沉积相、构造、盖层以及油源条件等综合因素的控制。作者分别从沉积相、构造、盖层、油源条件四个方面分析了对于油藏分布的影响,认为中川区长6油层组油藏是一个以构造-岩性油藏为主,岩性油藏次之的复合油藏。

| Abstract: | Previous studies think that the reservoir of Yanchang Formation in eastern North Shaanxi Slope in Ordos Basin is just controlled by sedimentary facies, and lithological trap is the major trap types. But research carried out by the author shows that the Chang 6 formation of Zhongchuan district in eastern North Shaanxi Slope is not only controlled by sedimentary facies, but also controlled by structure, cap rock, oil-source condition and so on. Influence of sedimentary facies, structure, cap rock and oil-source condition on the reservoir distribution has been analyzed, it＇s pointed out that Chang 6 formation in Zhongchuan district is a complex reservoir in which structural- lithological reservoir is major as well as lithological reservoir is in the second place. |
