Isicelo
Amafomu edwala:
Izingcezu ze-Oilfield roller cone drill zisetshenziswa kakhulu ezinhlotsheni ezahlukahlukene zokwakheka kwamadwala, kufaka phakathi i-sandstone, i-shale, i-mudstone, namadwala aqinile.Ukukhethwa kohlobo lwe-roller cone drill bit kuncike ebukhuni kanye nezakhiwo zokwakheka kwamadwala.
Izinjongo zokumba:
Izinjongo zokumba ziphinde zibe nomthelela ekukhethweni kwamabhithi okubhola ama-roller cone.Isibonelo, imithombo kawoyela yokumba kanye nemithombo yegesi yemvelo ingase idinge izinhlobo ezahlukene zezingcezu zokumba ukuze kuhlangatshezwane nezimo ezihlukahlukene zokuma komhlaba kanye nezidingo zemithombo yamanzi.
Isivinini sokumba:
Ukwakheka nokusebenza kwezingcezu zokubhoboza i-roller cone kuthinta ngqo isivinini sokumba.Lapho kudingeka ukubhola ngokushesha, kubalulekile ukukhetha izingcezu zokubhoboza ezinikeza ukusebenza kahle kokusika nokungagugi.
Indawo yokumba:
Ukumba endaweni ye-oilfield kuvame ukwenzeka ezimweni ezimbi kakhulu zemvelo, okuhlanganisa izinga lokushisa eliphezulu, ukucindezela okukhulu, nokuguga okuphezulu.Ngakho-ke, ama-roller cone drill bits kufanele akwazi ukusebenza ngokuqhubekayo ngaphansi kwalezi zimo futhi abe nempilo ende yesevisi.
Kafushane, izici nokusetshenziswa kwezingcezu zokumba i-oilfield roller cone zincike ezimeni zejoloji, izinjongo zokumba, kanye nezidingo zemvelo.Ukukhetha kahle kanye nokugcinwa kahle kwama-roller cone drill bits kubalulekile ekuthuthukiseni ukusebenza kahle kokubhola kanye nokunciphisa izindleko.Lezi zingcezu zokubhoboza zidlala indima ebalulekile ekumbiweni kwendawo kawoyela futhi zibaluleke kakhulu embonini yamandla.
Izici
Ukukhetha okubalulekile:
Izingcezu zokubhola i-Oilfield roller cone ngokuvamile zenziwa ngama-alloys aqinile (insimbi eqinile) njengoba zidinga ukusebenza endaweni eshisa kakhulu, enengcindezi ephezulu, kanye nasezindaweni ezigqokwa kakhulu.Ama-alloys aqinile ngokuvamile ahlanganisa izingxenye ze-cobalt ne-tungsten carbide, ezihlinzeka ngobulukhuni obuhle kakhulu nokumelana nokugqoka.
I-taper kanye nomumo:
Ukuma kanye ne-taper ye-roller cone drill bits ingalungiswa ukuze ivumelane nezimo ezihlukahlukene ze-geological kanye nezinhloso zokumba.Amajamo ajwayelekile afaka isicaba (izinyo eligayiwe), eyindilinga (faka izinyo), kanye ne-conical (i-tri-cone) ukuze kufakwe izinhlobo ezahlukene zamatshe.
Usayizi webhithi yokubhoboza:
Usayizi wezingcezu zokubhoboza ungakhethwa ngokusekelwe kububanzi nokujula komthombo ukuze kuzuzwe ukusebenza kahle kokubhola.Izingcezu zokubhola ezinkulu ngokuvamile zisetshenziselwa imithombo emikhulu enobubanzi obungububanzi, kuyilapho emincane ifanele imithombo yemithombo enobubanzi obuncane.
Izakhiwo zokusika:
Ama-roller cone drill bits ngokuvamile afaka izakhiwo zokusika ezifana nama-protrusions, imiphetho yokusika, noma amathiphu okusika ukuze asike futhi asuse amatshe amatshe.Ukuklanywa nokuhlelwa kwalezi zakhiwo kunomthelela isivinini sokumba nokusebenza kahle.
