摘要
对比了Mishra&.Caudle相关式、二次式和指数式三类无因次IPR方程的处理方法、性能特点和无固次采气指数。重点讨论了二次式特征参数α的物理意义及其影响因素。利用陕8井的四点试井数据进行了实例分析,指出了经验相关式和统计参数对于单点产能测试的局限性。
The analysis methods,characteristics and dimensionless productivity indexes of three types of dimensionless IPR equations,including Mishra and Caudle's correlation,quadratic and exponential equations,are compared.The physical meaning of characteristics parameter α of quadratic equation and its influence factors are mainly discussed.The example analysis of 4-point well loding data shows the limitations of correlations and empirical parameters in single point deliverability test.
