研究了低渗透油藏低速非达西径向流的动边界问题,给出了高精度的积分解,分析了启动压力梯度对压力分布的影响,发现启动压力梯度越大,井底附近压力下降越快,外边界传播越慢．
The low-velocity non-Darcy radial flow in low permeability reservoirs has been studied. The high-precision integral solution is given. The influence of starting pressure gradient on the pressure distribution is analyzed. The larger the starting pressure gradient, the lower the pressure near the bottom of the well The faster, the slower the outer border.
