ABSTRACT = {Theoretical analyses and experimental results show that gas wettability
plays an important role on gas-well production. In the study, the gas-wet ability parameter of gas vs. liquid ζ<sub>G-L</sub>, calculated from the proposed formula in the sessile
drop method, used to measure gas wettability of microscopic pore models treated
by fluorocarbon polymer Zonyl8740. Following that, the effect of gas-wetness on
gas-water two-phase seepage in models was studied by stereomicroscope with a
camera. Research results show that, under the condition of the pore structure is
constant and displacement velocity is very slow, capillary force is the main motivation for two-phase seepage, and gas wettability has a crucial influence on gas/water
interface, displacement characteristics, and distribution of gas and water. It is valuable for development of water flooding gas reservoirs.},
