Three-Phase Dynamic Displacement Measurements of Relative Permeability in Porous Media Using Three Immiscible Liquids.

摘要

An experimental investigation is conducted to examine the simultaneous motion of three phases in porous media. Limited research has been done in this area; therefore, the work is exploratory in nature. Experimental apparatus is constructed to enable the flow of three immiscible fluids through a one-dimensional, horizontal glass bead packed core. The main objective of the research is to map the relative permeabilities of the fluids in the interior region of the ternary diagram through a series of dynamic displacement water floods. Fluid relative permeabilities and saturations during the dynamic displacement experiments are calculated from the three-phase extension of the two-phase dynamic displacement theory of Welge's permeability ratios, and Johnson, Bossler and naumann's two-phase method of determining individual relative permeabilities.
