| 摘 要： | 以胜坨油田二区东营组三段（以下简称东三段）为例，提出以非均质综合指数为表征参数，以其平面等值图为依据研究目的层不同开发时期储层的平面非均质性。分析了开发初期、开发中期和开发后期的非均质特征，得到了不同时期非均质性的变化规律；探讨了储层平面非均质性与剩余油分布的关系。研究表明，东三段储层的平面非均质程度随注水开发而变化；开发初期以中等—较强非均质性为主，开发中期非均质性增强，开发后期以较强非均质性为主；中部非均质性相对较强，西北部相对较弱；沉积微相主体部位的非均质性变弱，侧缘部位的非均质性变强；平面非均质性增强的趋势仍将持续下去。约75%的剩余油分布在较强非均质性的储层中。

| Abstract: | Taking the third member of dongying formation in the second block of Shengtuo oilfield as research object, the paper deals with reservoir plane heterogeneity in different development stages based on heterogeneous synthetic index and its plane contour map. The heterogeneous characteristics in different development stages are analysed, and the variation regularities are obtained. Besides, the relationship between the reservoir plane heterogeneity and the distribution of remaining oil is also discussed. The results prove that the degree of reservoir plane heterogeneity varies with the process of the further waterflood development. In the earlier stage the degree of reservoir heterogeneigy is mainly middle to relatively strong; in the middle stage it is stronger; and in the later stage it is mainly relatively strong. According to statistic analysis, about 75 percent remaining oil is distributed in the reservoir with relatively stronger heterogeneity. |
