本文对目前国内外油田广泛应用的IPR预测产量方法,进行了有关影响因素的校正,并提出了两种适合现场使用的速算法。这两种方法,对于机械采油井改变抽级参数、改变油井工作制度、制订采油工艺方案、自喷井转抽设计、区块或单井动态分析预测都可以采用。本方法适用于流压、静压、含水、措施等多因素的变化,便于矿场采油技术人员及工人掌握和使用。
This paper corrects the influencing factors of IPR prediction yield widely used in oilfields at home and abroad, and proposes two speed algorithms which are suitable for on-site use. These two methods can be used for changing the pumping parameters of a mechanical production well, changing the working system of the well, formulating the production process, switching from injection well to pumping, block or single well dynamic analysis and prediction. This method is suitable for multi-factor changes such as flow pressure, static pressure, water content and measures to facilitate the mastery and use of oil recovery technicians and workers in the mine.
