ABSTRACT = {The condensate gas reservoir output could be enhanced significantly
with the gas-wetting reversal FC-1. However, changes in the wettability have been
shown to affect dispersion properties of clay minerals in condensate gas reservoir.
With the gas-wetting realized on the montmorillonite (MMT), zeta potential and
cation exchange capacity (CEC) change with wettability reversion were studied
in this paper, and the mechanism of it was also analyzed. The zeta potential of
100 ∼ 200 mesh MMT reached to -17.27mV and gradually approached to nondispersion condition; with FC-1 concentration increased, CEC decreased sharply
from 2.14 to 0.2. The microstructure of MMT was analyzed by SEM and TEM,
and conclusions were drawn that fluorocarbon chain FC-1 had been attached on the
surface of MMT particles and formed a gas-wetting reversal film which maintains
their stability.},
