摘要
根据大港油田西58-8小断块边水油藏地质及生产特征,采用油藏工程以及数值模拟两种方法,计算了水体体积,并对该区的开发方式进行了优化论证。在油藏工程计算水体体积中,应用了补加虚拟含油区域,建立了半圆形非定态水侵模型,利用物质平衡方程,计算结果与油藏数值模拟计算结果一致。
According to the geology and production characteristics of edge water reservoir of West 58 - 8 small fault block in Dagang oilfield, using two methods including reservoir engineering and numerical simulation calculates the volume of water body and optimizes and demonstrates the development scheme of the area. During the calculation of the volume of water body of reservoir engineering, water invasion model of semicircle nonstationary state is built by adding virtual oil - bearing area; the calculation result of material balance equation is similar to that of reservoir numerical simulation.
