油井含水经济极限分析

文章主要针对进入开发中后期的老油田面临油井含水上升、产量递减的问题，运用盈亏平衡分析原理，建立不同油井含水经济极限模型，井据此将油井分为A、B、C、D四类井。同时，运用单因素影响分析法，反算油井可承受的最低油价、最低开井时率及最高单井年操作成本，以便进行分类管理。

Analysis of Economic Limit of Water-Containing Oil Well

In view of the problem of rising water content and falling oil output that is encountered by old oil fields at their intermediate or late stage of production, this paper sets up water content economic limit models for different oil wells by means of breakeven analysis. According to such models oil wells are classified into four categories of A,B,C and D. Using one-factor influence analysis the author makes an inverse calculation of the lowest acceptable oil price, the least open well rate and the highest single well operation cost for oil fields for the purpose of classified management.
