Njengegazi lemboni, uwoyela uthatha isikhundla esibalulekile esu lamandla.Isihluthulelo sokwandisa ukukhiqizwa kukawoyela ezweni lami ukuthuthukisa ubuchwepheshe bokumba uwoyela.Ubuchwepheshe be-tube obunwebekayo buwubuchwepheshe obusha obubalulekile bukawoyela negesi ubuchwepheshe obusha obukhiqizwa futhi bathuthukiswa ekupheleni kwekhulu leminyaka elidlule nasekuqaleni kwaleli khulu leminyaka.Kuyindlela yomshini noma ye-hydraulic esetshenziswa ngaphansi komhlaba ukuhambisa ikhoni yokwandisa ukusuka phezulu ukuya phansi noma ukusuka phansi kuya phezulu ukwenza i-casing Insimbi ikhubazekile unomphela epulasitiki ukuze kuzuzwe inhloso ye-casing enwetshiwe eduze nodonga lomthombo.Ukusetshenziswa kobuchwepheshe beshubhu obunwebekayo kungathuthukisa kakhulu ukusebenza kahle kokukhiqizwa kobunjiniyela bokumba ekuthuthukisweni kukawoyela negesi, konga abasebenzi, izinto zokwakha, isikhathi nezindleko, futhi kukhuthaze ukuthuthukiswa kobunye ubuchwepheshe obuhlobene.Isiphathimandla sobunjiniyela bakawoyela base-US u-Cook sichaza ubuchwepheshe beshubhu obunwebekayo ngokuthi "ukumba uwoyela "Iphrojekthi yokufika inyanga" ingenye yobuchwepheshe obubalulekile embonini kawoyela negesi ekhulwini lama-21, futhi impahla yeshubhu yokwandisa ingenye yezinto ezibaluleke kakhulu. izindaba ezibalulekile kubuchwepheshe beshubhu lokunwetshwa.
Isakhiwo sensimbi ye-Duplex ikakhulukazi sakhiwe i-ferrite ne-martensite, eyaziwa nangokuthi insimbi ye-martensitic duplex.Inezici zokunwetshwa okungakhiqizi isivuno, amandla esivuno esiphansi, amandla aphezulu okunyakazisa nokumatanisa kahle kwepulasitiki, futhi kulindeleke ukuthi ibe yinto ekhethwayo yokwakhiwa kwamapayipi okunweba embonini ye-petroleum.Izici ezinhle kakhulu zensimbi enezigaba ezimbili ikakhulukazi zincike ku-morphology nenani le-martensite, futhi izinga lokushisa lokucisha linomthelela omkhulu enanini le-martensite kunsimbi yesigaba esikabili.
Idizayine ukwakheka kwamakhemikhali okufanelekile kwensimbi yesigaba esikabili yamashubhu okunweba, futhi yafunda umphumela wokushisa okucishayo kusakhiwo se-microstructure nasezicini zokuwumshini zensimbi yesigaba esikabili.Imiphumela ibonisa ukuthi njengoba izinga lokushisa lokucisha likhuphuka, ingxenye yevolumu ye-martensite ikhula kancane kancane, okuholela ekwandeni kwamandla esivuno namandla aqinile.Uma izinga lokushisa lokucisha lingu-820 ℃, insimbi enezigaba ezimbili zamashubhu okunwetshwa ingathola ukusebenza okuhle kakhulu okuphelele.
