The unsteady Darcy flow and the Darcy flow in composite reservoirs through porous medium, double medium and triple medium are special cases of their own.
单一介质、双重介质、三重介质非定常达西渗流及组合油藏达西渗流,只是上述问题的特殊情况。
The results show that: (1) a liquid flow through low permeability porous media has characteristics of non Darcy flow and there are starting pressure gradients;
