摘　　要：建立了一种新型的油井流入动态曲线方程 ,它适用于注水保持压力开发的油田采油井底出现油、气、水三相流动时流入动态的计算。该方程很好地解释了矿场稳定试井中出现的“拐弯型”流入动态曲线的特征 ,并可用来确定油井最低允许流动压力 ,预测不同含水、不同流动压力下采油井的产量。This paper establishes a new type of dynamic curve equation of oil well in flow which is adapt to calculation for in flow dynamic appearing oil,gas,water there phase at production bottom hole of the oilfield developed by water injection to keep the pressure.This equation interprets the characteristics of “inflexion type” in flow dynamic curve arising in field steady well test very well,determines the low permitted flowing pressure and predicts the oil well's productivity under condition of different water content and flowing pressure.
