Cov kauj ruam rub me ntsis yog ib qho kev xyaum me ntsis feem ntau tsim los siv rau hauv cov qauv mos xws li xuab zeb, av nplaum, lossis qee cov pob zeb mos.Txawm li cas los xij, lawv yuav tsis ua haujlwm zoo hauv cov pob zeb ntxhib lossis cov pob zeb nyuaj.Kev siv xws li drilling dej qhov dej, mining, geothermal.environmental thiab tshawb nrhiav drilling.Thaum twg ua tau, lawv yuav tsum tau siv los laum qhov pilot qhov vim tias lawv tsim cov txiav uas yooj yim tshaj plaws rau log.
3 tis kauj kauj ruam rub cov khoom yog ib qho kev tsim kho ntawm cov hlau hlau cam khwb cia nrog tungsten carbide txiav cov lus qhia thiab ntsuas sab kom ntseeg tau lub neej ntev.Nws muaj 3 tis thiab 3 qhov dej ntws tawm.Piv nrog rau 4 tis, 3 tis kauj ruam rub cov khoom yuav tho nrawm dua thiab nruj, qhov ntev, luv dua thiab tsis tshua muaj zog.Rotary rooj ceev ntawm cov kauj ruam rub cov khoom yuav tsum nyob nruab nrab ntawm 60 thiab 80 rpm nrog lub teeb yuag ntawm me ntsis (WOB).
3 tis cov kauj ruam rub cov khoom yog cov cuab yeej siv nyiaj txiag thaum drilling softer geological formations thiab qhov tob tob, lawv tau tsim tshwj xeeb rau cov mos tomedium formations, xws li av nplaum, Loam, Silt, Feem ntau-rau-nruab nrab cov av uas muaj qee qhov dej, thiab lwm yam. raug pom zoo rau drilling hauv Mining, Kev Tshawb Fawb, Ib puag ncig, Dej zoo, Geo Txauv, thiab lwm yam.
Lus Cim: Txoj kab uas hla thiab xov qhia raws li saum toj no yog ib txwm loj, lwm qhov ntau thiab tsawg yog muaj nyob rau hauv kev thov.
