本文结合王场油田潜四段的地质及开发特点,提出综合开采动态、沉积环境和测井资料,研究剩余油饱和度分布的方法。通过分析计算,绘制出各主力油砂体的剩余油饱和度等值图及生产井的纵向剩余油分布曲线,总结了剩余油饱和度在平面及纵向上的分布规律,指出了油田挖潜调整的方向,经部分区块和少数井的调整实施,收到了较好的效果。
Based on the geology and development characteristics of the fourth member of Wangchang Oilfield, this paper presents a method of comprehensively analyzing dynamic, sedimentary environment and well logging data and studying the remaining oil saturation distribution. Through the analysis and calculation, the residual oil saturation maps of the main oil sands and the longitudinal residual oil distribution curves of the production wells are plotted. The distribution rules of residual oil saturation in the plane and the longitudinal direction are summarized. Direction, through the adjustment of some blocks and a few wells to implement, received good results.
