Abaphakathiiyithuluzi elibalulekile elisetshenziswa embonini kawoyela negesi ukuqinisekisa ukubekwa kahle kwe-Wellbore kanye nokusebenza kokonga. Zezinhlobo ezahlukahlukene ezitholakalayo,abasebenza kanzimabadumile ngamandla abo nokusebenza kahle, ikakhulukazi ngemithombo efunwa kancane. Ake sithambeke ngokujulile kwizici nezinzuzo zale mikhiqizo enamandla.
Abasebenza kanzimazenziwe ngensimbi eqinile, zibenza bakhule kanzima futhi bamelana nokugqoka nokudabula. Lawo mandla ayabavumela ukuba babekezelele izimo ezinzima babevame ukuhlangana nokudla. Ngaphezu kwalokho, ukwakhiwa okuqinile kwalaba bakhungo baqinisekisa ukusebenza okungaguquki ngisho nasezindaweni eziyinselele.
Isici esingukhiye seabasebenza kanzimabacindezelwe futhi bacindezele. Lawa maqhawe asebenza njengamabhele ngesikhathi sokujikeleza kwamapayipi, anciphisa izidingo ze-torque futhi andise ukusebenza kahle kokusebenza. Ukwakhiwa okuqondile kwama-blades kuvumela ukujikeleza kwamapayipi okubushelelezi, okungenamthungo, ngcono ukusebenza kokumba okuphelele.
Leziabaphakathizitholakala kumamodeli amabili: i-blade eqondile kanye ne-helical blade. Imodeli ye-blade eqondile inikezela ukugxila okuhle nokusekelwa okuhle kwezindawo ezifanele ze-Wellbore. Ilungele imithombo enezidingo ezilula, futhi ivame ukusetshenziswa ekusebenzeni kokumba ngezidingo eziphansi.
Ngaphezu kwalokho, umklamo we-helical blade usiza ukuvimbela ukufakwa kwesiteshi noma okuphelele. Ngokufuya isiyaluyalu,abaphakathiKhuthaza ngisho nokusatshalaliswa kosimende, ukunciphisa ubungozi bezindawo ezibuthakathaka noma izikhala ku-venment sheath. Lokhu kuthuthukisa ukwehlukaniswa kwe-zonal futhi kuthuthukisa ubuqotho obuphelele bomthombo.
Ekuphetheni,abasebenza kanzimabangamathuluzi aqinile, aqinile futhi asebenzayo wemithombo efunwa kancane. Ukwakhiwa kwensimbi okuqinile nokucindezelwa kanye nama-blades kuqinisekisa ukuncishiswa okuhle nokuncishiswa kwe-torque ngesikhathi sokujikeleza kwamapayipi. Imodeli ye-blade eqondile isiza ukubekwa kahle kwe-Wellbore, ngenkathi imodeli ye-helical blade idonsa isiyaluyalu, ithuthukisa ukusebenza kahle futhi isekela imikhuba emihle yokumanzisa. Ngokusebenzisaabasebenza kanzima, opharetha bangathuthukisa ukusebenza kahle kanye nobuqotho, kuqinisekisa impumelelo yokushayela kanye nokusebenza kokonga.
