摘要
考虑启动压力梯度和介质变形系数的影响,推导了变形介质低渗透油藏油井产能方程。根据此模型可得到不同介质变形系数以及不同启动压力梯度条件下的油井指示曲线和采油指数曲线。计算结果表明:在相同的生产压差条件下,油井产量和采油指数随着介质变形系数和启动压力梯度的增大而降低。
Production equation of oil well was established for low permeable reservoirs of media deformation considering starting pressure gradient and deformation coefficient.Indicative curves and productivity index curves can be obtained according to this model under the conditions of different deformation coefficient and different starting pressure gradient.The calculation results show that production and productivity index of oil well decrease with increasing of permeability deformed coefficient and with increasing of starting pressure gradient.
