摘　　要：准确认识和评价油水井生产能力,是油田进行合理配产配注和开发调整的基本依据。在综合分析油水井基本产能公式和实际生产动态变化的基础上,建立了累积产液量、注入量与生产压差积分的关系,并用综合产液指数、综合吸水指数,来反映油水井的实际生产能力;而在实际生产过程中,开采条件变化产生的影响可以直观地反映在不同阶段油水井的生产能力变化上,通过计算不同阶段的综合产液指数、综合吸水指数,可以准确分析和评价不同开发阶段、不同条件下,油水井综合生产能力和变化趋势。实例应用表明,利用本文建立的方法,计算过程简捷、分析结果准确,可以为油藏开发调整和油井措施的实施奠定基础。Based on a comprehensive analysis of the basic productivity formula and the dynamic changes in actual production performance,it was established the relationship among the cumulative fluid production,water injection volume and the integral of production pressure. The integrated liquid production index and the comprehensive water index were used to reflect the actual production capacity of oil wells. In the field,variation of the production capacity of oil wells in the different stages can reflect the impact of production- condition changes directly. By calculating the integrated liquid production index and the comprehensive water index in different production stages,the overall production capacity of oil wells and trends in different stages and under different conditions can be analyzed and evaluated exactly. The practical application showed that the proposed method has a simple calculation process and precise results to lay the foundation for the adjustment of oilfield development and the implementation of well stimulations.
