Libopeho tsa majoe:
Oilfield roller cone drill bits li sebelisoa haholo mefuteng e fapaneng ea mafika, ho kenyeletsoa sandstone, shale, mudstone, le hard rocks.Khetho ea mofuta oa li-roller cone drill e itšetlehile ka boima le thepa ea sebopeho sa majoe.
Lipheo tsa ho cheka:
Lipheo tsa ho cheka li boetse li susumetsa khetho ea likotoana tsa ho cheka li-roller cone.Mohlala, liliba tsa oli tse chekang le liliba tsa khase ea tlhaho li ka hloka mefuta e fapaneng ea likotoana tsa ho cheka ho amohela maemo a fapaneng a jeoloji le litlhoko tsa liliba.
Lebelo la ho phunya:
Moralo le ts'ebetso ea li-roller cone drill bits li ama ka kotloloho lebelo la ho cheka.Ha ho hlokahala ho cheka ka potlako, ho bohlokoa ho khetha likotoana tsa ho cheka tse fanang ka ts'ebetso e phahameng ea ho itšeha le ho se mamelle.
Tikoloho ea ho cheka:
Ho cheka sebakeng sa oli hangata ho etsahala maemong a feteletseng a tikoloho, ho kenyeletsoa mocheso o phahameng, likhatello tse phahameng le moaparo o phahameng.Ka hona, li-roller cone drill bits li tlameha ho khona ho sebetsa ka nako e telele tlas'a maemo ana 'me li be le bophelo bo bolelele ba tšebeletso.
Ka bokhuts'oane, litšoaneleho le ts'ebeliso ea likhechana tsa ho cheka li-oilfield roller cone li ipapisitse le maemo a jeoloji, sepheo sa ho cheka, le litlhoko tsa tikoloho.Khetho e nepahetseng le tlhokomelo ea lisebelisoa tsa ho cheka li-roller cone li bohlokoa bakeng sa ho ntlafatsa bokhoni ba ho cheka le ho fokotsa litšenyehelo.Lithako tsena tsa ho cheka li bapala karolo ea bohlokoa ho chekoeng ha oli 'me li bohlokoa haholo indastering ea matla.

Khetho ea thepa:
Likotoana tsa ho cheka li-cone tsa Oilfield hangata li entsoe ka li-alloys tse thata (litšepe tse thata) kaha li hloka ho sebetsa maemong a mocheso o phahameng, khatello e phahameng le libaka tse apereng haholo.Li-alloys tse thata hangata li kenyelletsa likarolo tsa cobalt le tungsten carbide, tse fanang ka boima bo botle le ho hanyetsa ho roala.
Taper le sebopeho:
Sebopeho le taper ea likotoana tsa ho cheka li-roller cone li ka fetoloa ho lumellana le maemo a fapaneng a jeoloji le merero ea ho cheka.Libopeho tse tloaelehileng li kenyelletsa sephara (leino le sililoeng), selikalikoe (leino la kenya), le conical (tri-cone) ho amohela mefuta e fapaneng ea libopeho tsa majoe.
Sekhahla sa ho cheka:
Boholo ba likotoana tsa ho cheka li ka khethoa ho ipapisitsoe le bophara le botebo ba seliba ho fihlela ts'ebetso e nepahetseng ea ho cheka.Lithako tse khōloanyane tsa ho cheka li atisa ho sebelisoa bakeng sa liliba tse bophara ba bophara bo boholo, ha tse nyenyane li loketse liliba tse nang le bophara bo bonyenyane.
Mehaho ea ho itšeha:
Likotoana tsa ho cheka li-roller cone hangata li na le meaho e sehang joalo ka li-protrusions, lithapo tse sehiloeng, kapa malebela a chisel ho seha le ho tlosa mafika.Moralo le tlhophiso ea meaho ena e ama lebelo la ho cheka le katleho.
