I-oyile yesitya yi-aumbhobho wentsimbi ongenamthungoesetyenziselwa ukuxhasa udonga lomthombo weoli kunye negesi yegesi ukuze kuqinisekiswe ukusebenza okuqhelekileyo kweoli yeoli ngexesha lenkqubo yokugaya kwaye emva kokugqitywa.Kuya kusetyenziswa iileya ezininzi zequla ngalinye ngokobunzulu obuhlukeneyo kunye neemeko zejoloji.Isamente iya kusetyenziselwa ukufaka isamente emva kokuba ibhobhoyi ibaleka.Yahlukile kumbhobho we-oyile kunye nombhobho we-drill kwaye ayikwazi ukuphinda isetyenziswe.Yimpahla enokulahlwa.Ngoko ke, ukusetyenziswa kombhobho we-casing akhawunti ngaphezu kwe-70% yazo zonke iipayipi ze-oyile.
Imibhobho ye-oyile ekhethekileyo isetyenziselwa ikakhulu ukugrumba ioli kunye nerhasi kunye nokuhanjiswa kweoyile negesi.Iquka umbhobho wokomba ioyile, umbhobho weoli kunye nombhobho wokutsalwa kweoli.Umbhobho wokugrumba i-oyile usetyenziswa ikakhulu ukudibanisa ikhola ye-drill kunye ne-drill bit kunye nokudlulisa amandla okugaya.I-oyile ye-oyile isetyenziselwa ukuxhasa udonga lomthombo ngexesha lokugaya kwaye emva kokugqitywa komthombo, ukwenzela ukuba kuqinisekiswe inkqubo yokugaya kunye nokusebenza okuqhelekileyo kweoli yeoli emva kokugqitywa komthombo.Umbhobho wokutsalwa kweoli uhambisa ikakhulu ioyile kunye nerhasi ezantsi kweoyile ukuya kumphezulu.
Isingxobo se-oyileyindlela yokuphila yokugcina ukusebenza kwequla le-oyile.Ngenxa yeemeko ezahlukeneyo zejoloji, imeko yoxinzelelo lwe-downhole inzima, kwaye ukunyanzeliswa, ukuxinzelela, ukugoba kunye noxinzelelo lwe-torsional lusebenza kumzimba wombhobho, obeka phambili iimfuno eziphezulu zomgangatho we-casing ngokwayo.Emva kokuba i-casing ngokwayo yonakaliswe ngenxa yesizathu esithile, ukuveliswa kwequla lonke kunokuncitshiswa okanye ukuchithwa.
Ngokwamandla ensimbi ngokwayo, i-casing inokwahlulwa ibe ngamabakala ahlukeneyo ensimbi, oko kukuthi, i-H40, J55, K55, N80, L80, C90, T95, P110, q125, V150, njl. Iimpawu eziphambili ziyi-139.77 * 72r- 2 177.89 * 19r-2 244.58 * 94r-2 244.5 * 10.03r-2 244.5 * 11.05r-2, njl Amanqanaba entsimbi ahlukeneyo amkelwa kwiimeko ezahlukeneyo zequla kunye nobunzulu bequla.Kwimeko-bume enomhlwa, i-casing ngokwayo iyafuneka ukuba ibe nokumelana nokuhlwa.Kwiindawo ezineemeko zejoloji ezintsonkothileyo, i-casing iyafuneka kwakhona ukuba ibe nokusebenza okuchasene nokuwa.
Iifom zokucutshungulwa kokuphela kwe-oyile ye-oyile: intambo emfutshane ejikelezayo, intambo ejikelezayo ende, intambo ye-trapezoidal, i-buckle ekhethekileyo, njl. ioli yonke kakuhle emva kokugqitywa.
