Iimpawu zeKhola kunye nePipe
Ikhola yokomba isetyenziswa kakhulu ekuboneleleni ngamasuntswana okomba ngoxinzelelo olufunekayo, ukuqinisekisa ukuba amandla okutsala agqithiselwa kumbhobho wokomba kunye nokubeka embindini isuntswana lokomba.Ngokutsho kwe-API Spec7-1 inkcazo, umgangatho wezinto eziphathekayo yi-4145H emva konyango lobushushu, unyango lokuqinisa intambo kunye ne-phosphate ukuze i-anti-ibambe ngcono.Kananjalo inokuveliswa ngokweemfuno zabathengi.
Ikhola ye-Heavy Weight Drill yinxalenye ebalulekileyo yokusebenza kwe-Jcdrillizixhobo zokomba ezantsi umngxuma.Iikhola zokubhola zibonelela ngobunzima kwibhithi yokugrumba ngokusebenzisa iifom.I-Rig drillers iyakwazi ukujonga ubunzima obusetyenzisiweyo kwi-bit ngokubeka iliso ngokusebenzisa izibalo ezilula, kunye nesikali sesalathisi sobunzima, kumgangatho we-rig.Iikhola zokubhola ziqhele ukuba ziinyawo ezingama-31 ubude, iindonga ezityebileyo, kunye nentsimbi enzima.Beza ibhokisi ngephini kunye noqhagamshelo olufana nolunjalo, ukuze badibane njengoko uninzi lufunekayo, ukufezekisa ubunzima obufunwayo.Iikhola zokubhola ziza ne-OD etyibilikayo, okanye zenziwe ngoomatshini abaneengcango ze-helical (iikhola ezizii-spiral).I-Jink igcina unikezelo lwesisa lweekhola ze-carbon steel drill kwisitokhwe.Injongo yeekhola zeKhola yeNkola kukubeka isixa esifutshane sesithuba phakathi kwesuntswana lokomba, kwaye kufutshane ne-bit stabilizer.Le yenye nje indlela i-Jcdrill ekunika ngayo ukukwazi ukulungelelanisa iimfuno zakho zokusebenza njengoko kuvela imingeni emngxunyeni.Ngokudibanisa esi sikhewu sifutshane phakathi kwebit, kunye nokuhlatywa kancinci, uqinisa i-BHA wright kancinci, unciphisa ukuhamba kancinci, ke ngoko, ukukhuthaza umngxuma othe ngqo.I-Jcdrill igcina unikezelo lwesisa lweekhola zentsimbi zekhabhoni kwisitokhwe.
