摘　　要：建立了一种新型的油井流入动态曲线方程，可用于不同流动压力下油井流入动态的计算，从理论上解释了矿场系统试井中流入动态曲线向压力轴偏转并出现最大产量点等实际问题。给出了油井最低允许流动压力的计算公式，分析了影响油井最低允许流动压力的因素。A new equation of inflow performance curve of oil well was established, which can be used to predict inflow performance of oil well in dmerent nowing pressares. It theoretically explains why inflow performance curve is deflected towards pressure axis and why the maximum oil production point occurs in field well testing. The formula for calculating the ndnimum allowable flowing pressure was then derived, and the control on the minimum allowable flowing pressure was analyzed.
