老君庙油田M油藏挖潜调整数值模拟研究

根据老君庙油田M油藏顶部区的油藏地质特征和开发生产历史,利用油田注水开发数值模拟软件研究其剩余油分布规律,在平面上和纵向上找到剩余油饱和度的相对富集区,提出了针对性的调整方案和选定新井井位,并预测其将来的开发生产动态,比较了开发效果;目前经生产实践证明此次数值模拟研究为该油田挖潜调整提供了科学的指导,达到了控水稳油的目的,产生了良好的经济效益和社会效益。

APPLICATION OF THE NUMERICAL SIMULATION ON WATER INJECTION DRIVE RESERVOIR TO IMPROVE PRODUCTION OF M RESERVOIR IN LAO JUNMIAO OILFIELD

The residual oil distribution in the top area of the m reservoir in Lao Junmiao oil field is studied by using the numerical simulation software for water injection reservoirs (OFIW) based on the geologic characteristics and production history of the reservoir. The relatively higher residual oil concentration areas are found in the vertical and lateral direction of the m reservoir. The artificial adjustment schedules and new wells’locations aredesigned and their future performance is predicted, and comparison of production efficiency for each plan is conducted. The present production data has demonstrated that the numerical simulation is successful in providing a scientific direction for the adjustment of the m reservoir, controlling water rate increasing, stabilizing the oil production rate and making a good economic and social profit.
