I-API 12 1/4 amayintshi eyi-hybrid bit yokumba i-hard rock deep deep oilwell

I-Hybrid drill bit inama-cones angu-3 nama-blade angu-3 angcono kabili kune-premium roller cone bits.
Ekuqaleni kwekhulu leminyaka elidlule, i-cone drill bit esikhundleni se-scraper ekusetshenzisweni kokwakheka kwe-abrasive kanzima, kodwa lo mshini wokubhoboza i-drill kanye nezinye iziphambeko ekubunjweni kwepulasitiki kubangelwa ikakhulukazi indima yokubamba iphakethe le-downhole udaka, kanye nokujula kokumba kanye nokucindezela kwe-bottomhole nokwanda. ingxenye yodaka, isenzakalo sepaki yodaka sizoba sibi kakhulu.Ukuze kuxazululwe le nkinga, ngokuhamba kweminyaka abakhiqizi abahlukahlukene bemishini yokubhoboza i-cone benza ukuthuthukiswa okuhlukahlukene, kodwa kwaba nempumelelo encane.Ngokucabangela i-fixed cutter blade noma i-drill bit mayelana nalokhu okungathinteki kangako, abantu baqala ukuzama inhlanganisela yezinhlobo ezimbili zama-drill bits.Ngokuthandwa kanye nokusetshenziswa kwamabhithi e-PDC kanye nobuchwepheshe bokusika be-PDC ukuze kuthuthukiswe i-fixed cutter PDC drill bit in anhlobonhlobo yokwakheka kancane kancane esikhundleni se-cone bit.Kodwa ekubunjweni okuqinile, okulimazayo kanye nemisebenzi eyinkimbinkimbi yokumba isiqondiso, ngenxa yokusebenza, i-PDC drill bit ayikwazi ukufaka i-cone bit.Ukuze udlale izinzuzo ze-roller cone kanye ne-PDC drill bits, inkampani yethu isanda kuthuthukisa i-roller cone ehlanganisiwe kanye ne-PDC bit yesizukulwane esisha sokubhola okuyinhlanganisela.Sethula i-composite drill Kukhona imiklamo emibili, eyodwa isayizi encane kabili iphiko, i-double-cone bit, enye inobukhulu obuthe ukukhudlwana bephiko le-Mito, i-tricone bit, Ngokusekelwe kulokhu kubhoboza amaphiko amane emimese kanye nezindwani eziyisithupha zokubhoboza i-PDC, futhi ama-vice blades kanye nezikhundla ezimfushane kwashintshwa usayizi wekhoni.Ngakho-ke, indawo ephakathi nendawo ye-borehole itholakala ophikweni lukadokotela ohlinzayo lwe-PDC cutter oluphelele lwamadwala, kanye nengxenye eseceleni yokumba imigodi ephothulwa abasiki bemigodi nama-blades kanye nengxenye ewumngcele yedwala elibhodlozayo eliphuka kanzima, ukuphuka kwamadwala. umphumela kuncike Isigaxa kanye izindwani nokukhwelana.
Ubuchwepheshe be-Hybrid drill bit buhlanganisa ama-roller cones kanye ne-PDC abasiki abangaguquki kube umklamo owodwa, onelungelo lobunikazi ukunciphisa isikhathi sokumba kanye nohambo lwezinhlelo zokusebenza eziyinkimbinkimbi kakhulu. ama-bits, lobu buchwepheshe bukhulisa i-ROP, bulimaza ukususwa kokusika, futhi businda ekwakhekeni okuxubene kakhulu ngokungaguquguquki kokusebenza nokulawula okuhle kakhulu kobuso bamathuluzi.
Ubuchwepheshe be-Hybrid drill bit
ama-roller cones kanye ne-polycrystalline diamond compact (PDC) abasiki abangashintshi babe yidizayini eyodwa, enelungelo lobunikazi ukuze kuncishiswe isikhathi sokumba kanye nohambo ezinhlelweni eziyinkimbinkimbi kakhulu.Ngamandla okuchotshozwa kwedwala nokuzinza kwama-roller cones kanye nokuphakama okusikayo kanye nesenzo sokugunda okuqhubekayo kwezingcezu zedayimane, lobu buchwepheshe bukhulisa i-ROP, buthuthukisa ukususwa kokusikwa, futhi businda ekubunjweni okuphambane kakhulu ngokusebenza ngokungaguquguquki nokulawula okuhle kakhulu kobuso bamathuluzi.Emhlabeni jikelele, izingcezu zethu zokubhola ezixubile zisetshenziswe emazweni angu-47 futhi sekumbiwe okwengeziwe
ngaphezu kwesigidi esingu-1 (304,800 m).
