| 摘 要： | 以宋芳屯油田南部区块为例,采用层次分析和模糊综合评判相结合的方法,对该油藏的水驱储量控制程度、水驱储量动用程度、可采储量、能量保持水平、能量利用程度、即时含水采出比、累积注水量、剩余可采储量采油速度、井网密度和注采井数比10项指标进行了评价,形成了一套水驱开发效果综合评价体系.评价结果认为该区目前水驱开发效果差,有必要进行井网加密及挖潜措施调整.

Integrated Evaluation of Waterflooding Development Effect in South Songfangtun Oilfield Based on Fuzzy Comprehensive Evaluation |
| |
| Abstract: | Taking south Songfangtun oilfield as an example,this paper evaluates its 10 indices by using analytic hierarchy process(AHP) and fuzzy comprehensive evaluation method,and then form a comprehensive evaluation system of waterflooding development effect.The 10indices are degree of water drive reserves control,water drive reserves producing degree,energy maintenance level,energy utilization degree,instantaneous water cut-recovery percent ratio,cumulative water injection volume,oil production rate of remaining recoverable reserves,well spacing density and injection-to-production-well ratio.The results show that the current waterflooding development effect is poor and it is necessary to take measures for well pattern thickening and tapping the potential. |
