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.
Taking the block of the southern part of Songfangtun Oilfield as an example, this paper uses the combination of AHP and fuzzy comprehensive evaluation to analyze the extent of waterflooding reserves control, utilization of waterflooding reserves, recoverable reserves, energy conservation, energy utilization, Instantaneous water production ratio, cumulative water injection volume, remaining recoverable reserves oil production rate, well density and well number than the 10 indicators were evaluated to form a waterflood development comprehensive evaluation system results show that the area At present, water flooding is ineffective in development and it is necessary to make well network encryption and tapping potential measures.
