摘要
低渗透油藏的流体渗流具有压力梯度 ,流动边界不断扩大 ,为此建立了低渗透油藏渗流的一种新的试井解释模型 ,此模型既能很好地近似实际渗流 ,又不需考虑动边界 ,便于用数值方法对数学模型的求解。此结果可用于低渗透油藏的试井分析。
With the low permeability reservoir development,the flowing bound ar y extends.Anew well test model with the startup pressure is developed to simulat e the real flow in the porous media.This model without considering moving bounda ry is easy to solve by using numerical method.The result can be used to the well test analysis in the low permeability reservoir.
