摘　　要：水驱体积波及系数和驱油效率是注水油田开展动态分析、评价水驱效果的重要参数,直接影响油田水驱采收率。基于注采井网评价水驱采收率的模型,推导出产量与井网表征量之间的指数关系,进而通过产量和井网资料拟合求出极限可采储量、水驱体积波及系数和驱油效率。同时,结合一定的水驱规律探讨了井网密度与注采井数比的关系。Volumetric sweep efficiency is an important index for engineers to make dynamic analysis and evaluate waterflood susceptibility in waterflood field, especially it brings direct influence on recovery.This paper deduces the exponential relationship between production and well network based on the evaluation model of recovery, using injection-production pattern,and obtains limit recoverable reserves through fitting between production and well network, then evaluates the volumetric sweep efficiency and waterflood efficiency.At the same time,this paper investigates the relationship between well spacing density and injector producer ratio ,combining with determinate waterflood discipline, as has definite leading meaning for current development evaluation and upper adjustment.
