Experimental study on flow properties of air foam in heterogeneous reservoir
Online published: 2014-04-06
This paper analyzed the percolation capacity and influencing factors of air foam in single homogeneous cores with different permeabilities and different gas-liquid ratios, and studied the fractional flow rates of parallel cores with different permeability ratios. The experimental results indicate that the larger the gas-liquid ratio is, the larger the flow resistance of foam system is; with the increase of permeability and volume of foam system injected, the resistance factor gets larger, and the blocking ability of foam system increases; the fluid diversion capacity is good while foam flow in heterogeneous reservoir, but with the increase of permeability ratio, the ability of foam system to divert liquid tends to decrease.
