商河油田商三区沙三上亚段剩余油分布研究

Remaining Oil Distribution in the Upper Position of Es_3 Member of Block Shang 3 in Shanghe Oilfleld

在精细油藏描述和精细油藏数值模拟的基础上,应用动态资料分析法和数值模拟法,对商河油田商三区沙三上油藏剩余油分布进行了定性与定量研究,指出其剩余油分布类型有3种:未动用或少动用的油砂体形成的剩余油、已动用油层的平面剩余油滞留区、层内非均质形成的剩余油。应用这些研究成果取得了良好的挖潜效果。

On the basis of precision reservoir description and the precision reservoir numerical simulation, qualitative and quantitative studies of remaining oil distribution in reservoirs are conducted in the upper position of Es3 member of Block Shang 3 in Shanghe Oilfield by using the methods of dynamic data analysis and numerical simulation. It is pointed our that there are 3 remaining oil distribution types: such as remaining oil formed by non-producing or less producing oil-bearing sandbodies retention area of remaining oil on the plane of produced pay zones and remained oil formed by heterogeneity within payzones. The research results are used with better effect.
