Exploration and Experience Summary of Workover Operation in T Gas Reservoir
T gas reservoir is a large-scale high-quality packaged gas reservoir.Since its development,it has gone through the production rise period and stable production period,and now it has entered the stage of pressurized production in the middle and later stage of production.At present,it is difficult to carry liquid in the production process.The reason is that the formation pressure of gas wells is generally low in the later stage of production,and the oil pipes of gas wells are of composite structure and generally have large pipe diameters.It is urgent to optimize the pipe string structure of problem wells.By studying the workover operation data,this paper analyzes the workover effect at this stage,summarizes the problems existing in the workover process,and provides valuable experience for the workover operation of other gas wells in this block.
