摘要
利用物理模拟驱油机理实验、岩心观察油层水洗状况、微观驱油实验、示踪迹监测、碳氧比、中子寿命测试以及数值模拟结果 ,建立断块各小层砂体水淹模式图及剩余油饱和度等值图 ,从定性认识到定量分析 ,详细研究了该断块的水淹特征及剩余油分布规律 ,并探索出针对“双高期”老油田不同剩余油潜力区分布特点进行挖潜对策的综合调整模式 。
Watered-out mode and residual oil saturation contour are established for each subunit sand by using experiment of physical modeling of oil displacement mechanism, core observed reservoir water-flushed status, micro oil displacement experiment, tracer monitoring, carbon/oxygen ratio, neutron lifetime, and numerical simulation. The watered-out features and residual oil distribution law in this fault block are studied qualitatively and quantitatively. Potential tapping measures are used according to different features of residual oil distribution in old oilfield in “double high period”. This provides reference to development and adjustment of similar reservoirs.
