Key Points of Quality Control and Supervision of Injection and Production Completion in Salt Cavern Gas Storage Wells
The injection and production completion of salt cavern gas storage well is the key to the construction and safe operation of gas storage well,and its quality directly affects the life and economic benefit of gas storage well.Through the analysis of the common problems in the process of injection and production completion,such as pipe string leakage,downhole tool failure,sealing test and un-qualified injection and production wellhead pressure test,combined with the on-site construction technology,specific supervision points and control measures are proposed from the three construction links of pre-injection-production completion sealing detection,injection-production completion,and post-injection-production completion sealing detection,which effectively intervene in the injec-tion-production completion operation of salt cavern gas storage well,and thus achieve the purpose of controlling and improving the in-jection and production completion quality of salt cavern gas storage well.
