ABSTRACT

Introduce the change rules of the front shape, the advancing angles, and the
gas flow resistance of water-displacing-gas, gas-displacing-water, oil-displacing-
gas, and gas-displacing-oil in details; in etched-glass network model, the
influence of gas wettability on fluid percolation status, the oil/gas/water
distribution, and the recovery; and the influence of cores with different gas
wettability on the gas permeability and the displacement characteristic.
