Meaho ea mafika:
Li-drill bits tsa olive roller cone li sebelisoa haholo mefuteng e fapaneng ea mafika, ho kenyeletsoa lejoe la lehlabathe, shale, seretse le majoe a thata. Khetho ea mofuta oa roller cone drill bits e itšetlehile ka thata le litšobotsi tsa lefika.
Lipakane tsa ho phunya:
Maikemisetso a ho tjheka a boetse a susumetsa kgetho ya dikotwana tsa ho tjheka tsa roller cone. Mohlala, dikotwana tsa oli tsa ho tjheka le dikotwana tsa kgase ya tlhaho di ka hloka mefuta e fapaneng ya dikotwana tsa ho tjheka ho dumella maemo a fapaneng a jeoloji le ditlhoko tsa wellbor.
Lebelo la ho cheka:
Moralo le tshebetso ya di-drill bits tsa roller cone di ama lebelo la ho tjheka ka ho toba. Ha ho hlokahala ho tjheka ka potlako, ho bohlokwa ho kgetha di-drill bits tse fanang ka bokgoni bo phahameng ba ho seha le ho hanyetsa ho tsofala.
Tikoloho ea ho cheka:
Ho cheka oli sebakeng sa oli hangata ho etsahala maemong a feteletseng a tikoloho, ho kenyeletsoa le mocheso o phahameng, khatello e phahameng, le ho senyeha ho hoholo. Ka hona, li-drill bits tsa roller cone li lokela ho khona ho sebetsa ka ho tsoelang pele tlas'a maemo ana 'me li be le nako e telele ea ts'ebeletso.
Ka bokhutšoanyane, litšobotsi le ts'ebeliso ea li-drill bits tsa roller cone tsa olifield li itšetlehile ka maemo a jeoloji, lipheo tsa ho cheka, le litlhoko tsa tikoloho. Khetho e nepahetseng le tlhokomelo ea li-drill bits tsa roller cone li bohlokoa bakeng sa ho ntlafatsa katleho ea ho cheka le ho fokotsa litšenyehelo. Li-drill bits tsena li bapala karolo ea bohlokoa ho chekeng olifield 'me li bohlokoa haholo indastering ea matla.
Litšobotsi
Khetho ea thepa:
Dikarolo tsa ho tjheka tsa khoune ya oli di atisa ho etswa ka ditshila tse thata (ditshepe tse thata) kaha di hloka ho sebetsa dibakeng tse nang le mocheso o phahameng, kgatello e phahameng, le ho robeha ho hoholo. Ditshila tse thata hangata di kenyelletsa dikarolo tsa cobalt le tungsten carbide, tse fanang ka thata e ntle le ho hanyetsa ho robeha.
Botenya le sebopeho:
Sebopeho le ho tenyetseha ha dikotwana tsa ho phunya di-roller cone di ka lokiswa ho latela maemo a fapaneng a jeoloji le dipheo tsa ho phunya. Dibopeho tse tlwaelehileng di kenyeletsa leino le bataletseng (leino le sitsweng), le chitja (leino le kentsweng), le le kobehileng (le-tri-cone) ho amohela mefuta e fapaneng ya mafika.
Boholo ba karolo ea ho phunya:
Boholo ba dikotwana tsa ho tjheka bo ka kgethwa ho latela bophara le botebo ba sekoti ho fihlella tshebetso e ntle ka ho fetisisa ya ho tjheka. Dikotwana tse kgolo tsa ho tjheka hangata di sebediswa bakeng sa dikoti tse kgolo, ha tse nyane di loketse dikoti tse nyane tsa bophara.
Meaho ea ho seha:
Hangata dikotwana tsa ho phunya dikhoune tse roller di na le meaho ya ho seha e kang dipotoloho, mathoko a ho seha, kapa dintlha tsa chisel ho seha le ho tlosa mafika. Moralo le sebopeho sa meaho ena di ama lebelo le bokgoni ba ho phunya.
