中文摘要：
针对低渗透油藏具有启动压力梯度和应力敏感性的特性,考虑油相相对渗透率、原油黏度、原油体积系数随压力变化,建立了考虑应力敏感性和启动压力梯度影响的低渗透油藏三相流油井流入动态方程,分析了影响流入动态曲线形态的因素。其结果对开发低渗透油田的油井流入动态预测具有实际指导意义。
英文摘要：
In accordance with the characteristic of starting pressure gradient and stress sensitivity existed in low permeability reservoirs,and considering the variety of oil relative permeability,oil viscosity and volume coefficient of oil in different pressure,the inflow performance equation of the oil,gas and water simultaneous seepage flow in low permeable reservoirs has been established considering the starting pressure gradient and stress sensitivity. The factors of effect on the shape of inflow performance curve has been analyzed. It is significant for the prediction of inflow performance of oil well in low permeability reservoirs developed.
