For fractured-porous reservoirs, fractures serve as the primary flow channels for both seepage and water production. Once a gas well starts producing water, the flow channels gradually become occupied by the aqueous phase, leading to a sharp decline in gas well productivity and a progressive weakening of water-bearing production capacity. This ultimately results in gas well flooding. Timely intervention with drainage gas recovery can effectively extend the water-bearing production capacity of gas wells, prolong their lifecycle, and enhance development efficiency. This study clarifies through water invasion flow experiments that fractures in carbonate rocks are the dominant seepage channels. The actual production dynamics of Well Y-1 further confirm that fracture distribution directly determines the pattern and direction of water invasion. Based on the water invasion mode and type of Well Y-1, a drainage gas recovery strategy is formulated according to the liquid-carrying capacity of the gas well at different production stages. The findings provide valuable insights for managing water-invaded wells of this type.
