ABSTRACT
Expound the preferential wettability of liquid on the solid surface in details
and the factors and laws influencing wettability of reservoir rocks’ surface; put
forward the wettability of gas on reservoir rocks’ surface—“gas wettability” in
some special circumstances—and further expound the research status of gas
wettability and super-hydrophobic theory in China and overseas; establish the
definition of gas wettability.

1.1 INTRODUCTION TO GAS WETTABILITY
1.1.1 Preferential Wettability of Liquid on the Solid Surface
“Wettability” refers to the phenomenon of liquid spreading visually along
solid surfaces due to molecular forces. The wettability of a solid surface can be
defined in several ways. Firstly, a quantitative definition can be given based on
the thermodynamics. The wettability of certain liquids to solids means
