Chapter 3: Classical flow theory in porous media
In classical flow mechanics in porous media, the influencing factors considered in the flow process are relatively simple, such as it is assumed that the medium is homogeneous and isotropic with intergranular pore structure, the fluid is a Newtonian fluid, the reservoir is under isothermal condition, the well is vertical well, etc. The classical flow problems in porous media mainly include the single-phase steady state flow, the multi-well interference, the elastic energy driven flow, the oil-water two-phase flow, the natural gas flow, the oil-gas two-phase flow and the gas-water two-phase flow. The first four problems are the key problems in this book.
