介绍了油田措施增油量计算的常规方法.针对该方法存在的不足,给出了考虑措施前产量递减时,措施累积增油量的计算方法.应用无因次指标—累积增产倍数比较两种方法的计算结果,并编制了措施增产效果评价软件.以中海油湛江分公司某油田换大泵措施为例,评价了措施的增产效果,研究了累积增产倍数随措施前产量递减率的变化规律.%Stimulation requirement and stimulation output occupy some ratio of the total investment and output, so there is need to establish a scientific stimulation evaluation method. Considering whether the production is decreasing or not, respective evaluation methods are established to compute the cumulative extra oil production and develops evaluation software. The utilization in CNOOC Ltd Zhanjiang Branch indicates that the method built is simple, accurate and provides a reliable basis for the oil field to arrange stimulation reasonably.
