I-J55 K55 N80 I-Oil Tubing kanye ne-Casing Steel Pipe
I-oil casing iyipayipi yensimbi esetshenziselwa ukusekela izindonga zemithombo kawoyela negesi ukuze kuqinisekiswe ukusebenza okuvamile kwawo wonke umthombo wamafutha ngemva kwenqubo yokumba nokuqedwa.Umthombo ngamunye usebenzisa izingqimba eziningana ze-casing ngokusho kokujula okuhlukene kokumba kanye nezimo ze-geological.I-cementing ye-cement isetshenziswa ngemuva kokuba i-casing yehliselwe emthonjeni.Ngokungafani namapayipi kawoyela namapayipi okubhoboza, ayikwazi ukuphinda isetshenziswe futhi iyimpahla esetshenziswa ngesikhathi esisodwa.Ngakho-ke, ukusetshenziswa kwe-casing akhawunti ngaphezu kwe-70% yawo wonke amapayipi omthombo kawoyela.
