API 5CT J55 daboolka saliidda iyo gaaska

Dabada J55 API ama tubbada waa mid ilaa xad caan ka ah qodista saliidda. Sababtoo ah heerka birta ee hooseeya ee J55,
waxaa loo isticmaalaa soo saarista saliid gacmeed iyo gaas. Sababtoo ah qiimaha hoose ee ka mid ah darajooyinka kale ee birta, waxay ku raaxaysataa ballaaran
codsiyada. Daaska J55 API ama tubbada ayaa si weyn loogu isticmaalaa soo saarista gaasta dabiiciga ah iyo methane dhuxusha,
waxaana si caadi ah looga heli karaa ceelasha gacmeedka, ceelasha dhulka hoostiisa, iyo ceelasha biyaha.

API 5CT J55 Qaababka Tubbinta Casing

Dusha sare ee dunta isku xidhka iyo API 5CT J55 Casing Tubing waa in ay ahaataa mid siman iyada oo aan wax jeex ah lahayn.
ama cilladaha kale ee saameyn xun ku yeelan kara xoogga iyo xiriirka dhow.

API 5CT J55 Casing Tubing waxaa lagu bixiyaa dhererka bilaashka ah 8m ilaa 13m iyadoo lagu saleynayo SY/T6194-96
caadi. Si kastaba ha ahaatee, sidoo kale waa la heli karaa wax aan ka yarayn dhererka 6m iyo tirada waa in aanay ka badnayn 20%.
