Ezimweni eziningi, kuphoqelekile ukuba kube nendlela yokuvala yonke imithombo ekwazi ukugeleza ngokwemvelo phezulu.Ukufakwa kwe-valve yokuphepha engaphansi komhlaba (SSSV) kuzonikeza leli khono lokuvala izimo eziphuthumayo.Amasistimu okuphepha angase asetshenziswe ngomgomo wokwehluleka ukuphepha kusuka kuphaneli yokulawula etholakala phezulu.
I-SCSV ilawulwa ngomugqa wokulawula wensimbi engagqwali ongu-¼” onamathiselwe ngaphandle kwentambo yeshubhu yomthombo bese efakwa lapho kufakwa ishubhu lokukhiqiza.Kuye ngengcindezi ye-wellhead, kungase kudingeke ukuthi ugcine i-psi engaba ngu-10,000 kulayini wokulawula ukuze ugcine i-valve ivulekile.
Ezinye izinhlelo zokusebenza:
I-capillary coiled alloy tubing yomjovo wamakhemikhali
Ulayini wokulawula we-hydraulic ongenalutho futhi ohlanganisiwe we-alloy tubing wamavalvu okuphepha angaphansi kolwandle
Izintambo zejubane, izintambo zokusebenza, nezinkaba zeshubhu lensimbi
I-Geothermal coiled alloy tubing
