Ukumbiwa kwemithombo kawoyela negesi kanye nokuthuthwa kukawoyela negesi, imikhiqizo esemqoka ihlanganisa: i-casing, ishubhu, ipayipi lokubhoboza, ikhola yokubhoboza, ipayipi lokubhola elinesisindo esisindayo, ipayipi elivaliwe, ipayipi lomugqa, ukuhlanganisa kanye nokuhlangana komdlwane.
(1)Isikhwamaiyipayipi elingububanzi obukhulu elisebenza njengesibambisi sesakhiwo sezindonga zemithombo kawoyela negesi, noma ibhore.usayizi:OD: 4 1/2'' ~ 20'' (114.3mm ~ 508mm);WT: 0.205' ' ~ 0.635'' (5.21mm ~ 16.13mm); UBUDE: R1, R2, R3
(2)Ishubhu:Ishubhu ipayipi elithutha uwoyela ongahluziwe negesi yemvelo ukusuka kungqimba lukawoyela negesi ukuya phezulu ngemva kokuphothula ukumba. Isetshenziselwa ukumelana nokucindezela okukhiqizwa phakathi nenqubo yezimayini.Isetshenziselwa Ukudluliswa Kwamafutha Negesi.
(3)Ipayipi lokubhoboza:Amapayipi okumba uwoyela enziwa ngensimbi yokumba ye-geological ngokugoqa okushisayo noma umdwebo obandayo. Ibanga: E75, X95, G105, S135. Isetshenziselwa ikakhulukazi ukuxhashazwa kukawoyela negesi.
