油田在进入高含水期开采后,进行注采系统的调整包括两个方面:一是调整油田现有井网系统;二是调整油田的注采压力系统。本文应用注采平衡分析的方法,采用理论分析和动态分析相结合的方式,确定了注水开发油藏合理的压力保持水平,为油田的开发规划、综合调整及日常生产管理提供重要的依据。
After entering the high water cut period, the adjustment of injection-production system consists of two aspects: one is to adjust the existing well pattern of the oil field and the other is to adjust the injection-production pressure system of the oil field. In this paper, the method of balance of injection and production analysis is adopted. By means of combining theoretical analysis with dynamic analysis, a reasonable pressure maintenance level of waterflooding reservoirs is determined, which provides an important basis for oilfield development planning, comprehensive adjustment and daily production management.
