本文针对油田注水开发的特点，考虑油田产量递减和含水率递增的实际情况，利用技术经济学中的动态盈亏平衡分析方法，结合油田注水开发投资的估算、收入的估算和支出的估算，建立了油田注水开发的经济评价模型。利用Excel软件在一定原油价格分别测算不同内部收益率、不同井深、不同含水率情况下的单井日产量；然后利用SPSS统计软件对测算得到的样本数据进行回归分析，得到了内部收益率与单井日产、井深、含水率之间的函数关系；最后根据建立的回归分析模型对某油田的2个区块进行应用，检验该经济评价方法的实用性。

According to the characteristics of water flooding,and taking into consideration the reality of oil produc-tion decline and moisture content increase,this article establishes an economic evaluation model for water flooding, which combines estimation of investment,income and expenditure. The method used here is called dynamic break-even analysis in technical economics. First,the authors calculate the daily production per well at different internal rates of return,different depths,different water contents at a certain oil price by Excel;then they use SPSS to con-duct a regression analysis of the sample data and get the functional relations between the internal rate of return and the daily production per well,depth,water content respectively. Finally,the regression analysis model is applied to two blocks of a certain oil field to test its practicability.
