1) water–drive-gas
水气驱替
1.
To study the fluid flow among coal in the course of water–drive-gas water injection in theory, when water injection is carried out, according to the fact that coal is double porous medium, when water injection is carried out, according to the fact that coal is double porous medium, the differential equations set of water plane radical flow are discussed according to two kinds of condition.
在此条件下,考虑到煤层孔隙喉径,隙间无流体流动,仍为单一裂隙渗流,其水气驱替与单纯孔隙水气驱替相近,渗流为稳定流时情况也与此相同。
