摘要
通过对低渗透油田地质状况和生产资料的分析(以国内某油田Y区块为例),确定中高含水期油水分布状况。通过产量劈分,计算出每个层位的月产油量、累计产油量和月产液量、累计产液量,得到每个小层的水驱特征曲线,进而得到各小层剩余油储量以及剩余油平均饱和度。根据计算地质储量和给定地质储量得到的剩余油饱和度的对比,可以确定各小层的实际地质储量。
This paper analysed geological conditions and production materials of low permeability oilfields (a domestic oilfield Y block as an example) . determined the oil and water distribution in the middle and high water content stage. Through the production split, calculated monthly for each oil layer, total oil production and the monthly fluid volume, total liquid production, and gained water drive curve of each small layer, and then get the remaining oil in a small layer , and the average saturation. According to the residual oil saturation contrast between the calculated geological reserves and given geological reserves, the actual geological reserves of each small layer can be determined.
