AI Technical Summary
Technical Problem
Existing technologies are insufficient to effectively address the production recovery problem caused by liquid accumulation in gas wells. Traditional methods suffer from drawbacks such as high equipment costs, high energy consumption, complex operation, or limited efficiency.
Method used
By calculating the theoretical critical liquid carrying capacity and comparing the actual gas production with the theoretical critical liquid carrying capacity, the operating parameters or gas injection volume of the gas well can be adjusted in real time to achieve continuous production of the gas well.
Benefits of technology
It extends the lifespan of gas wells, enables continuous production and output recovery, reduces equipment and energy consumption, and simplifies operating procedures.

Abstract
The application provides a method, system, device, equipment and medium for restoring the yield of a gas well with liquid accumulation, comprising the following steps: step 1, obtaining real-time data of a target well, and calculating the real-time theoretical critical liquid carrying capacity of the target well according to the obtained real-time data; step 2, obtaining the actual gas production of the target well, comparing the obtained actual gas production with the theoretical critical liquid carrying capacity, and adjusting the operating parameters of the target well in real time according to the comparison result, wherein: if the actual gas production is greater than the theoretical critical liquid carrying capacity, the target well continues to produce at the current operating parameters; if the actual gas production is less than or equal to the theoretical critical liquid carrying capacity, gas injection is performed on the target well until the actual gas production reaches a set value; the application controls the actual gas production of the target well to be greater than the theoretical critical liquid carrying capacity by means of gas injection on the target well, thereby realizing the continuous production of the target well and improving the life cycle of the target well.
