On the theory of injection of moist steam into a porous medium

Abstract

A plane one-dimensional problem on the injection of moist steam into a porous medium is treated. An investigation is performed of the effect of the parameters, which define the initial state of the porous medium, boundary pressure, temperature, and moisture content of steam, on the rate of propagation of hydrodynamic and temperature fields in the porous medium.

Molecular dynamic simulation of wet water vapour transport in porous medium

“…In particular, one of the methods for extracting highly viscous bitumen grades of oil from the subterranean depths is based on the dilution of the contents of the porous medium by means of pumping coolants. The simplest and environmentally friendly coolant is wet steam containing small drops of water [Shagapov, 2004]. In addition, with the help of heated water vapour, the filtering elements of collectors are cleaned from sediments of the solid phase (for example, paraffins, gas hydrates and ice floes) on walls of the porous medium.…”
