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 dynamic curve equation of oil well inflow was established, which can be used to calculate the inflow of oil well under different flowing pressures. The practical problems of flowing inflow dynamic curve to the pressure axis and the maximum output point were explained theoretically. The formula of the minimum allowable flow pressure of the well is given, and the factors that affect the minimum allowable flow pressure of the well are analyzed.
