RC Drilling ntsis
Ib qho RC (rov qab ncig) drilling me ntsis yog ib hom kev xyaum me me uas siv rau hauv qhov rov qab ncig drilling, ib txoj hauv kev drilling uas siv rauj los tsoo cov av thiab pob zeb thaum drilling. Lub RC Drilling Bit yog txuas rau qhov kawg ntawm lub laum qia, uas yog qis rau hauv av. Raws li lub laum qia yog tig, lub laum me ntsis txiav los ntawm cov av thiab pob zeb, tsim ib tug borehole. Cov cuttings yog ces coj rov qab mus rau saum npoo los ntawm ib tug cais yeeb nkab hu ua rov qab ncig system. RC Drilling Bit feem ntau yog siv rau hauv kev tshawb nrhiav pob zeb thiab kev sim geotechnical, vim nws nrawm dua thiab tsis tshua kim dua lwm hom kev drilling, xws li pob zeb diamond drilling.

Lub RC Drilling (RC) cov khoom 'nce precision thiab raug nyob rau hauv drilling thiab drilling cov hauj lwm raug xa mus rau raws li RC drilling me ntsis kom zoo dua. RC cov khoom tuaj yeem tswj tau los ntawm thaj chaw deb thiab cov kws tshaj lij thaum lub sijhawm drilling txij li lawv tau haum nrog cov sensors thiab tswj cov tshuab. Yog li ntawd, tej zaum yuav muaj kev vam meej ntau dua thiab txo cov khoom siv los yog qhov chaw drilling puas. Tsis tas li ntawd, RC cov khoom siv feem ntau xyaum ua kom raug thiab ntawm qhov nrawm dua li cov lus qhia los yog cov khoom siv kho tshuab. Kev ua haujlwm drilling tuaj yeem ua tau zoo dua thiab ua haujlwm tau zoo.
