摘　　要：运用一种新的数学解法,研究双重介质有界地层低速非达西渗流问题。基于低渗透渗流理论,建立起双孔介质有界地层低速非达西渗流模型并予以求解,编程绘制出井底压力动态样版曲线,获得低速非达西流三段拟合实用复合图版。Starting with the fundamental flow principles for low permeability reservoir,low velocity non-darcy porous flow model considering dual pore medium bounded formation has been established and solved by new methods. The programming has drawn the dynamic type curves of bottom-hole pressure from which we eventually got three fitting practical type curves of low velocity non-darcy porous flow.
