Rov qab Circulation Bit

 

 

Rov qab Circulation Bit thiab Down-The-Hole (DTH) cov khoom yog ob qho tib si ntawm cov khoom siv drilling siv nyob rau hauv ntau yam kev siv drilling, tab sis lawv ua haujlwm sib txawv thiab muaj cov qauv tsim kom tau raws li cov kev xav tau ntawm cov txheej txheem drilling.

 

 

Rov qab Circulation Bit thiab Down-The-Hole (DTH) cov khoom yog ob qho tib si ntawm cov khoom siv drilling siv nyob rau hauv ntau yam kev siv drilling, tab sis lawv ua haujlwm sib txawv thiab muaj cov qauv tsim kom tau raws li cov kev xav tau ntawm cov txheej txheem drilling. Nov yog qhov sib piv ntawm RC cov khoom thiab DTH khoom:

 

Rov qab Circulation ntsis:
Txoj Kev Drilling: RC Drilling suav nrog kev siv cov dej drilling hauv cov yeeb nkab laum thiab sau cov txiav los ntawm qhov nruab nrab ntawm cov yeeb nkab laum. RC me ntsis yog tsim los kom tshem tawm cov txiav tawm hauv qab ntawm qhov borehole thiab thauj lawv mus rau saum npoo.

 

Bit Design: Rov qab Circulation Bit muaj qhov tsim tshwj xeeb nrog qhov qhib dav ntawm qhov chaw thiab cov channel lossis flutes ntawm lub ntsej muag me ntsis. Cov yam ntxwv no pab txhawb kom muaj txiaj ntsig zoo ntawm cov txiav thiab cov kua dej drilling, tso cai rau cov cuttings yuav tsum tau nqa los ntawm cov raj sab hauv ntawm RC laum yeeb nkab.

 

Daim ntawv thov: Rov qab Circulation Bit feem ntau yog siv rau hauv kev tshawb nrhiav ntxhia thiab qib tswj kev drilling. Lawv yog cov tsim nyog rau softer formations thiab yog optimized rau zoo sau cov qauv zoo los ntawm kev txo cov paug.

 

Down-The-Hole (DTH) ntsis:
Drilling Method: DTH drilling yog cov txheej txheem percussion drilling qhov twg rauj nyob tom qab lub laum me ntsis. Compressed cua yog siv los tsav lub rauj lub piston, uas ntaus lub nraub qaum ntawm me ntsis, tsim kom muaj zog hammering nyhuv uas ua rau lub pob zeb tawg.

 

Ntsis Tsim: DTH cov khoom muaj cov qauv tsim nrog cov nyees khawm lossis chisels ntawm lub ntsej muag me ntsis. Qhov me ntsis yog raug rau cov kev cuam tshuam loj heev, thiab qhov tsim ntawm cov nyees khawm lossis chisels txawv raws li qhov nyuaj ntawm cov pob zeb tsim tau drilled. DTH cov khoom muaj nyob rau hauv ntau yam qauv, xws li convex, flat face, thiab concave, kom haum rau ntau hom pob zeb.

 

Daim ntawv thov: DTH cov khoom siv feem ntau siv hauv kev tsuas, khawb av, dej zoo drilling, geothermal drilling, thiab kev tsim kho. Lawv ua tau zoo nyob rau hauv cov pob zeb nyuaj thiab abrasive uas yuav tsum tau muaj kev cuam tshuam loj rau kev nkag mus.

 

Qhov txawv tseem ceeb:
Txoj Kev Drilling: RC cov khoom siv rov qab rov qab drilling, qhov twg cov dej drilling yog siv los thauj cov txiav mus rau saum npoo los ntawm qhov nruab nrab ntawm cov yeeb nkab laum. DTH cov khoom siv hauv percussion drilling, qhov twg rauj nyob tom qab qhov me me ua rau muaj kev cuam tshuam rau lub pob zeb.

 

Kev tshem tawm Cuttings: Rov qab Circulation Bit yog tsim los rau kev tshem tawm kom zoo ntawm cov txiav hauv qhov rov qab ncig drilling, kom ntseeg tau cov qauv zoo. DTH cov khoom tsom rau kev rhuav tshem lub pob zeb kom zoo thiab tsis cuam tshuam nrog kev ncig ntawm cov dej drilling rau kev tshem tawm.

 

Tsim nyog tsim nyog: RC cov khoom tsim nyog rau cov qauv softer thiab siv rau kev tshawb nrhiav. DTH cov khoom siv tau zoo hauv cov pob zeb nyuaj thiab abrasive thiab feem ntau siv hauv kev siv mining thiab kev tsim kho.

 

Hauv cov ntsiab lus, kev xaiv ntawm RC cov khoom thiab DTH cov khoom nyob ntawm qhov tshwj xeeb drilling txoj kev, geological tej yam kev mob, thiab lub hardness ntawm lub pob zeb tsim yog drilled. Txhua hom me ntsis yog tsim los txhim kho kev ua tau zoo raws li cov txheej txheem drilling nws tau npaj rau.
