I-API engu-12 1/4 inches hybrid bit yokubhoboza imisele yamanzi ejulile ngamatshe aqinile

I-hybrid drill bit inama-cone amathathu kanye nama-blade amathathu angcono ngokuphindwe kabili kune-premium roller cone bits.
Ekuqaleni kwekhulu leminyaka elidlule, i-cone drill bit esikhundleni se-scraper ekusetshenzisweni kwe-hard abrasive formations, kodwa le drill drill shale kanye nokunye ukushiyeka ekwakhekeni kwepulasitiki kubangelwa kakhulu indima yokubamba i-pressure downhole mud pack, futhi ngokujula kokubhoboza kanye nengcindezi ye-bottomhole kanye nokwandisa isilinganiso sodaka, i-mud pack izoba yingozi kakhulu. Ukuze kuxazululwe le nkinga, eminyakeni edlule abakhiqizi abahlukahlukene be-cone drill bits benze intuthuko ehlukahlukene, kodwa ngempumelelo encane. Uma kucatshangelwa i-fixed cutter blade noma i-drill bit kulokhu, abantu baqala ukuzama inhlanganisela yezinhlobo ezimbili ze-drill bits. Ngokuthandwa nokusetshenziswa kwe-PDC bits kanye nobuchwepheshe be-PDC cutter bokuthuthukisa i-fixed cutter i-PDC drill bit ezinhlotsheni ezahlukene ze-formations kancane kancane ithatha indawo ye-cone bit. Kodwa ezinhlotsheni ezinzima, ezi-abrasive kanye nemisebenzi yokubhoboza eyinkimbinkimbi, ngenxa yokusebenza, i-PDC drill bit ayikwazi ukuthatha indawo ye-cone bit. Ukuze kudlale izinzuzo ze-roller cone kanye ne-PDC drill bits, inkampani yethu isanda kuthuthukisa i-roller cone ehlanganisiwe kanye ne-PDC bit yesizukulwane esisha se-composite drill. Sethula i-composite drill Kunemiklamo emibili, eyodwa iphiko elincane eliphindwe kabili, i-double-cone bit, enye ikhudlwana kancane iphiko le-Mito, i-tricone bit. Ngokusekelwe kulezi drill, amaphiko amane emimese kanye nama-blade ayisithupha e-PDC drill bit, kanye nama-vice blades kanye nezikhundla ezimfushane kwashintshwa usayizi we-cone. Ngakho-ke, indawo ephakathi ye-borehole itholakala ephikweni lodokotela i-PDC cutter ephelele yamadwala aqhekekile, kanti ingxenye engaphandle ye-borehole drill eqediwe ngabasiki be-cutter nama-blades kanye nengxenye engaphandle yedwala elibolile kahle iphuka nzima kakhulu, umphumela wokuphuka kwedwala uncike ku-cone nama-blades kanye nokuhlangana.
Ubuchwepheshe be-hybrid drill bit buhlanganisa ama-roller cone kanye nama-PDC fixed cutters abe umklamo owodwa, onelungelo lobunikazi ukuze kuncishiswe isikhathi sokubhoboza kanye nohambo ezinhlelweni eziyinkimbinkimbi kakhulu. Ngamandla okuchoboza amatshe kanye nokuqina kwama-roller cone kanye nokuphakama kokusika kanye nesenzo sokugunda esiqhubekayo sama-diamond bits, lobu buchwepheshe bukhulisa i-ROP, buthuthukisa ukususwa kokusika, futhi buyasinda ekubunjweni okuxubene kakhulu ngokusebenza okuvumelanayo kanye nokulawula ubuso bamathuluzi okuhle kakhulu.
Ubuchwepheshe be-hybrid drill bit
Ama-roller cones kanye nama-polycrystalline diamond compact (PDC) aqiniswe abasiki abe ngumklamo owodwa, one-patent ukuze kuncishiswe isikhathi sokubhoboza kanye nohambo ezinhlelweni eziyinkimbinkimbi kakhulu. Ngamandla okuchoboza amatshe kanye nokuqina kwama-roller cones kanye nokuphakama kokusika kanye nesenzo sokugunda esiqhubekayo sama-diamond bits, lobu buchwepheshe bukhulisa i-ROP, buthuthukisa ukususwa kwama-cuttings, futhi businda ukwakheka okuxubile kakhulu ngokusebenza okuvumelanayo kanye nokulawula ubuso bamathuluzi okuhle kakhulu. Emhlabeni jikelele, ama-hybrid drill bits ethu asetshenziswe emazweni angu-47 futhi abhoboze okuningi.
