Condensate liquid in porous media can prevent gas from exiting when the pressure is lower than the dew point pressure in the condensate gas reservoir. This can lead to liquid block and sharp decreases in gas yield. In this work, super‐amphiphobic materials were used to remove the liquid block and recover the product. The experiments indicated that this method can effectively remove the damage of liquid block and improve the productivity of the gas well.
