Rov qab ncig (RC) drilling thiab percussion drilling yog zoo ib yam nyob rau hauv uas lawv ob leeg koom nrog kev siv cov drilling rigs mus rau hauv lub subsurface. Txawm li cas los xij, lawv yog cov txheej txheem sib txawv nrog cov txheej txheem sib txawv thiab lub hom phiaj.
RC Drilling: Nyob rau hauv RC drilling, compressed cua los yog dej yog siv los ua cov thawj drilling kua, uas yog circulated los ntawm lub laum yeeb nkab thiab me ntsis, thiab ces mus txog ntawm lub annular qhov chaw ntawm lub laum yeeb nkab thiab lub borehole phab ntsa. RC drilling feem ntau yog siv rau hauv kev tshawb nrhiav thiab mining, nrog rau qee qhov kev siv ib puag ncig thiab geotechnical drilling. Cov kua dej drilling pab tshem tawm cov txiav tawm ntawm qhov borehole, tso cai rau cov qauv rov qab zoo dua thiab nkag mus sai dua.
Percussion Drilling: Percussion drilling, tseem hu ua rauj drilling los yog rotary percussion drilling, suav nrog kev siv lub tshuab percussive los rhuav tshem cov pob zeb. Lub laum me ntsis txuas mus rau hauv qab ntawm txoj hlua laum thiab rov ua dua los ntawm kev ua rauj, xws li los ntawm lub qhov rauj los yog los ntawm ib qho rauj saum toj kawg nkaus rau ntawm lub rig. Percussion drilling feem ntau yog siv rau hauv cov pob zeb tawv tawv uas cov txheej txheem sib dhos ua ke yuav ua haujlwm tsawg dua. Nws yog feem ntau siv hauv kev tsim kho, tsuas, thiab geotechnical drilling tej yaam num.
Thaum ob qho tib si RC drilling thiab percussion drilling koom nrog kev siv cov drilling rigs thiab cov cuab yeej tshwj xeeb, lawv txawv ntawm lawv cov txheej txheem drilling, hom dej drilling siv, thiab lawv cov ntawv thov. RC Drilling tsom rau kev tshem tawm kom zoo thiab cov qauv rov qab los hauv kev tshawb nrhiav thiab kev tsuas, thaum percussion drilling feem ntau yog siv los rhuav tshem cov pob zeb nyuaj hauv ntau daim ntawv thov drilling.
