法哈牛油田法21断块剩余油分布研究

根据油水井的计算实例分析，可确定出法哈牛油田主力断块各油层所有层段的剩余油饱和度、剩余地质储量。将油层组各井点的剩余油饱和度标志在平面上绘制成饱和度等值线图，并结合各砂岩组孔渗资料绘制的等值线图可很直观的观察剩余油饱和度的分布状况。总结了以砂岩组为最小单位的油层、各层段的剩余油分布规律，并结合法21断块剩余油分布的影响因素对该区剩余油的挖潜提出了几项措施，为油田的增油上产服务。

Research on Remaining Oil Distribution of F21 Block in F Oil Field

Based on the analysis of computing examples of the water and oil wells, the saturation degree of surplus oil and remaining possible reserves in all oil layers of main block of the F oil field can be calculated. By marking the saturation degree of surplus oil at each well point in oil layer on plane to draw its contour chart and combined with porosity and permeability contour charts of each sand stone group, the saturation degree of surplus oil can be observed directly. Taken sand group as a unit, surplus oil distribution law of oil player and each single layer is generalized. At the same time, measures for potential exploration of remaining oil are put forward based upon the factors that influence the distribution of remaining oil of the block, which will benefit the increase in yield of the oil field.
