摘　　要：异常高压油藏在开发过程中随着原油被采出，地层压力下降，上覆地层的压应力增大，孔隙空间发生变化，渗透率随之也发生变化，此时，渗透单是地层压力的函数。通过渗流力学理论，建立了异常高压油藏采油指数随压力变化的教学模型。While the crude was produced from abnormal high pressure reservoir, descent of the formation pressure will occur, compressive stress of overbueden formation will increase, permeability will also change with POre space. Hence the permeability is a function of formation pressure. Based on percolation mechanics theory, the mathematics model of productivity index vs pressure was develoPed for an abnormal high pressure reservoir in this paper.
