摘　　要：Vogel建立了溶解气驱油藏无因次IPR曲线方程,Standing在Vogel方程的基础上建立了非完善井的IPR曲线方程。但这一方程并未得到国内外学者的认可,纷纷指出Standing方程计算结果不正确。本文找出了Standing方程错误的原因即引用了错误的流动效率计算公式。作者在正确理解、引用两相流流动效率计算公式的基础上重新建立了溶解气驱油藏非完善井流入动态方程,该方程的正确性得到了数值模拟结果的佐证。Vogel established dissolved gas drive reservoir dimensionless IPR curve equation, and Standing established the IPR curve equation of imperfect oil well based on Vogel equation. But this equation has not been recognized by scholars at home and abroad, and it is pointed out that the calculation result of Standing equation is not correct. This paper found out the standing equation error reason that he referenced of the error flow efficiency calculation formula. Based on the correct understanding and referencing of the two phase flow efficiency calculation formula, the authors re-established the dynamic equation of imperfect oil well l flow in the dissolved gas drive reservoir, and the correctness of the equation has been proved by the numerical simulation results.
