I-API 5CT J55 casing kawoyela negesi

I-J55 API casing noma ishubhu iyinto evamile ekubholeni uwoyela. Ngenxa yezinga eliphansi lensimbi ye-J55,
isetshenziselwa ukukhipha uwoyela ongajulile kanye negesi. Ngenxa yentengo yayo ephansi phakathi kwamanye amabanga ensimbi, ijabulela kabanzi
izicelo. I-J55 API casing noma ishubhu isetshenziswa kakhulu ekukhishweni kwegesi yemvelo kanye ne-coalbed methane,
futhi ingatholakala ngokuvamile emithonjeni engashoni, emithonjeni ye-geothermal, nasemithonjeni yamanzi.

Izici ze-API 5CT J55 Casing Tubing

Ubuso bomucu wokuhlanganisa kanye ne-API 5CT J55 Casing Tubing kufanele bushelelezi ngaphandle kokudabula, burr
noma okunye ukukhubazeka okungase kube nomthelela omubi emandleni nasekuxhumekeni okuseduze.

I-API 5CT J55 Casing Tubing inikezwa ngobude bamahhala ukusuka ku-8m kuya ku-13m ngesisekelo se-SY/T6194-96
okujwayelekile. Kodwa-ke, iyatholakala futhi ubude obungekho ngaphansi kuka-6m futhi ubuningi bayo akufanele bube ngaphezu kwama-20%.

Ukonakala okukhulunywe ngenhla akuvunyelwe ukuthi kuvele endaweni engaphandle ye-API 5CT J55 Casing
Ukuhlanganisa amashubhu.

Noma ikuphi ukuguga okufana nokuqhekeka, ukuhlukana, umugqa wezinwele, ukuqhekeka noma utwayi akwamukelekile kukho kokubili ngaphakathi nangaphandle.
ubuso bomkhiqizo. Zonke lezi ziphambeko kufanele zisuswe ngokuphelele, futhi ukujula okususiwe akufanele
idlule u-12.5% ​​wokuqina kodonga okuzisholo.
