Ukuhlukaniswa komgodi wamanzi

Njengomshini wokumba oyi-rotary, umshini wokumba umthelela kanye nomshini wokumba oyinhlanganisela izigaba ezi-3.

I-Rotary drill

Ngokunyakaza okuphindaphindayo okuqondile kwethuluzi lokubhola, i-drill bit ishaya phansi kwembobo ukuze kuqhekeze idwala.Ilula, kodwa ayinalo uhlelo lokuguquguquka okujikelezayo, ngakho-ke ama-cuttings awakwazi ukususwa ngesikhathi esifanayo ne-rig, okuholela ekusebenzeni kahle okuphansi.Ukujula kokumba ngokuvamile kuphakathi kwamamitha angu-250, kanti okunye kungafinyelela ku-500 ~ 600 amamitha.Izinhlobo eziyinhloko yilezi ezilandelayo.I-drill ye-percussion elula esebenzisa isisindo seyunithi yezinhlamvu yokubhoboza ukuze ishaye ukwakheka.Engxenyeni engezansi yethuluzi lokumba kukhona i-disc ye-zhang ecijile ye-zhang, lapho ithuluzi lokumba ngaphansi kwesenzo sesisindo salo ukuya phansi, i-valve yokubamba ivulekile, idonsa iphuzu le-disc kumjikelezo wobubanzi obuyi-1 m esike edwaleni. , bese udlula ithuluzi lokuphakamisa intambo, bamba i-disc ekuvaleni udoti wenqubo ku-cone ecijile bese ubeka phambili i-wellhead ivuleke futhi ngemva kokubamba ukukhipha i-cutting disc.I-thrust grab cone ivame ukubhobolwa ekujuleni okungamamitha angama-40 kuye kwangama-50, okujule kakhulu kube yi-100 kuya ku-150 m.

I-wire drill enomthelela wentambo yenziwe insika kanye ne-pulley yayo yokuphakamisa phezulu, intambo yocingo, indlela yokuthinta, amathuluzi okubhola (okuhlanganisa ipayipi lokubhoboza kanye nebhithi lokubhoboza), injini, njll. (Umfanekiso 4).Ngesikhathi sokusebenza, injini ishayela umshini womthelela ngomshini wokudlulisa bese ishayela intambo yocingo ukwenza ithuluzi lokumba libuyele phezulu naphansi.Lapho wehla, isisindo sokubhoboza senza ibhithi linqamuke futhi liphule idwala, kuyilapho liya phezulu lincike ekubambeni kwentambo yocingo.Ukuphakama kwethuluzi lokumba eliwayo, okungukuthi usayizi we-stroke, kunqunywa ngokuvumelana nezimo zokwakheka kwamadwala, ngokuvamile 0.5 ~ 1 m, idwala eliqinile elinenani eliphezulu;Imvamisa yomthelela ivamise ukuba izikhathi ezingama-30~60/min.Ama-cuttings asikwa emhlabathini ngesilinda sokumpompa isihlabathi, futhi angasetshenziswa ukubhola ithuluzi lokubhoboza elihlanganisa i-drill bit kanye nesilinda sokumpompa isihlabathi.Ukubhoboza nokukhipha ama-cuttings kwenziwa ngesikhathi esifanayo, ukuze ama-cuttings anqunywe ngqo ku-cylinder yokupompa, futhi ngemva kokuba ukuqoqwa kugcwele, ithuluzi lokugaya liyaphakanyiswa futhi ukusika kuthululwe.Ukuze kuthuthukiswe ukumelana nokugqokwa kanye nesivinini sokubhola sebhithi, i-tungsten steel powder ivamise ukuvela ekugcineni kwebhithi ukuze ibe i-alloy repair welding bit.I-compound drill.
