Abstract

Abstract:

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.

Key words: pore types, diagenesis, controlling factors, these cond member of Jialingjiang Formation, southern Sichuan Basin
