摘　　要：异常高压低渗透油藏多依靠较充足的天然能量开发,开发效果受压敏效应和启动压力梯度的影响。在考虑其影响因素的基础上,应用非线性渗流理论和油藏工程基本原理,提出了异常高压低渗透油藏弹性开发设计方法,并通过算例分析了其影响因素。该方法对异常高压低渗透油藏的弹性开发设计具有十分重要的指导意义。Low permeability reservoirs with abnormal high pressure are usually developed by natural energy,and the recovery is subject to pressure-sensitive effect and threshold pressure gradient.Based on the consideration of these effects,a method of depletion development is proposed and its influence factors are analyzed by using the nonlinear theory of fluid flow in porous media and the principles of reservoir engineering.This method has a profound significance on the development of low permeability oil reservoirs.
