摘要
蠡县斜坡高106井区尾砂岩段油藏位于一个向东南倾伏的鼻状构造上,具有典型的油水倒置特征。以岩心的物性分析、构造特征和微相分析为基础,认为:高106井区尾砂岩段油藏构造简单,区域内无断层,因此不存在上倾方向的构造遮挡,油藏的油水倒置主要是因为构造高部位为河道边缘,物性较差,导致油气难以充注,并与地层坡度较缓和沉积微相的差异等因素有关。
Weishayan oil reservoir of well block Gao 106 in Lixian slope is located in a nos- ing anticline structure which is plunging into southeast, and it has a typical characteristic of oil-water inversion.Based on analysis of physical properties of rock,structural feature and microfacies analysis, I think that the structure of the Weishayan oil reservoir of well block Gao 106 is very simple without any faults and the result indicate that the characteristic of oil-water inversion is mainly determined by the river edge in the high point ,whose physical properties are so poor that oil and gas are difficult to charge, and other factors such as the gentler slopes,the difference of the mierofacies and so on.
