摘要
为解决目前不能定量评价油田注采适应性的问题,通过引入地饱比、注采强度比等概念,研制地饱比-注采比、注采强度比-开井油水井数比两个关系图版,将两个图版划分为五个区,对两个图版进行交汇,制定25种注采状况相应的调整对策。根据各区块的实际注采状况,明确调整对策,在动态调整过程中有针对性地制定下一步具体的调整措施。利用该方法实现区块注采适应状况的定量评价,使油田开发调整更加有章可循,在杏北油田1-3区应用取得了较好效果。
In order to solve the problem of incapability to quantitatively evaluate injection-production adaptability,this paper introduces the concepts of formation pressure/initial oil saturation ratio and injection-production intensity ration,plots the charts of formation pressure/initial oil saturation pressure ratio vs.injection-production ratio and injection-production intensity ratio vs.opened oil well/water well number ratio.It divides the two charts into five areas,crossplots the two charts,and works out solutions for 25 types of injection-production status.According to the actual injection-production status of each area,it adjusts the solution and determines to adjustment method for next step in the process of dynamic adjustment.This method is applied in Block 1-3 in Xingbei Oil Field with a good effect.
