Abstract

Abstract:

The relationships between facies and potential of 527 sand bodies in Jiyang Depression were analyzed. The connotations of facies-potential coupling effects on reservoir were discussed on the bases of two-dimensional simulation experiments on different sand configuration as well as high pressure and high temperature simulation of oil migration and accumulation in cores. The results showed that there exist different characteristics of facies-potential coupling effect on reservoir in different scales. In the sand body scale, there mainly reflects the different type of sedimentary facies, the characteristics of oil and gas accumulation are also different. In the sand layer scale, there mainly reflects the different of oil migration pathway and oil pay zone attributed to heterogeneity of the sand,variations of sand-shale composition and permeability difference. In the core scale, the flow characteristics of oil-gas migration and oil saturation are different. The oil-filled sand-bodies mainly lie in the two-high and one-low areas of PFR model for facies-potential coupling effect on reservoir developed by using energy condition, mobility and reservoir capacity. Facies-potential coupling effect on reservoir is a quantitative model with power function and can be used to predict hydrocarbon-bearing.

Key words: Jiyang Depression, facies-potential coupling, pool-forming mechanism, physical simulation, sand-body characteristics, oil-gas migration, hydrocarbon bearing prediction

摘要：

通过对济阳坳陷527个砂体的"相"和"势"关系统计,结合二维砂层组合模拟实验和高温高压岩心石油运移和聚集实验,探讨了"相-势"耦合的内涵。不同尺度下,具有不同的"相-势"耦合控藏特征:砂体尺度下,主要体现在沉积相类型不同,油气聚集特征与油气充满度不同;砂层尺度下,主要体现在砂层的非均质性、砂泥岩组合和渗透率级差不同,油气运移路径和通道与含油层位不同;岩心尺度下,主要体现在视流度不同,油气运移的渗流特征和含油饱和度大小不同。成藏砂体主要位于用能量条件、流动能力和储集能力建立的"相-势"耦合控藏的PFR模式的二高一低区。"相-势"耦合定量模型为幂函数形式,可用来判别砂体含油气程度,进行含油气性预测。
