Abstract:

An experiment of displacement of gas by water by using an unsteady-state flow method and by forcing back pressure is introduced in this paper. According to Buckley-Leverett displacement theory, the relative permeability formula suitable for the displacement of gas by water is derived, and experiment data are obtained. It is of practical significance to the development and performance analysis of boundary bottom water gas reservoirs.
