Aimed at the problem of leakage on Xmas tree in natural gasfield,combining with the structural characteristics of Xmas tree and the working principle of leak sealing technology under pressure,corresponding measures to control the leakage parts were put forward.Through optimizing the structure of plugging fixture and choosing suitable sealing grease,a reasonable leak sealing technology under pressure was developed.And the technology was improved and its reliability was verified through a large number of simulation experiments.The application results show that the technology of leak sealing under pressure can successfully plug natural gas leakage and eliminate potential safety hazards of gas wells.It has the advantages of short construction period,safety,and environmental protection,and it is a new method for safe production of gas well.
