油井产能预测方法的研究

摘要

Accurate prediction of oil well productivity is the basis of well design and dynamic analysis. Generally,the integrated IPR curve under water cut is based on Ptrobras method,which combines Vogel formula of oil flow with flow equation of single phase flow. In this paper,a practical solution method for oil well productivity prediction is proposed,which solves the problem of disconnection between theory and practice.%准确预测油井产能是油井设计和动态分析的基础,含水情况下的综合IPR曲线一般是采Ptrobras方法,这种方法是把油流的vogel公式和单相水流的流动方程相结合而导出的.本文提出了油井产能预测的实际求解方法,解决了理论与实际应用相脱节的问题.
