Abstract
To study the seepage characteristics of foam in the formation, combining the gas-liquid injection experiment and theoretical analysis to study the shunt effect and additive effect, the authors point out that in the nonhomogeneous strata, whether the gas or foaming agent is injected first, shunt effect of foam can be generated. After alternative multislug injection, the outflow fluid velocity in nonhomogeneous strata is the same, which in fact is the same fluidity. When the foam blocks effectively, the migration velocity of the gas-liquid slug in high- and low-permeability formation is subject to the pore. The ratio of high- and low-permeability formation is inversely proportional to the porosity. The foam additive effect should be further explored.
