DTH raujkev saib xyuas
1. Lub DTH Rauj yuav tsum ib txwm tig nrog sab tes xis thaum drilling txij li qhov kev sib txuas thiab kev sib koom ua ke yog cov xov sab xis.
2. Txhawm rau kom ntseeg tau tias lub laum me ntsis nkag mus rau hauv pob zeb stratum smoothly, qhov tsawg kawg nkaus ntawm kev cuam tshuam thiab lub zog quab yuam yuav tsum tau siv thaum lub sij hawm drilling.
3. Nws yog ib qho tseem ceeb kom sib npaug qhov hnyav ntawm cov cuab yeej drilling nrog lub zog propulsive. Qhov hnyav ntawm cov cuab yeej drilling yuav tsum tau kho lub zog thruster.
4. Lub DTH Rauj feem ntau tig ntawm qhov ceev ntawm 15 mus rau 25 rpm. Lub chiseling ceev yuav nce nrog nce rotational ceev. Txhawm rau tiv thaiv me ntsis los ntawm kev hnav dhau lawm, kev sib hloov ceev yuav tsum tau txo qis ntawm cov pob zeb tawv.
5. Cov cuab yeej percussion yuav tsum tau siv ntau zaus rau kev yuam tshuab kom tshem tawm lub qhov hauv qab vim tias qhov thaiv qhov thaiv thiab lub qhov yuav txhaws qhov laum.
6. Lub DTH Rauj yuav tsum tau lubricated kom zoo; tsis ua li ntawd tuaj yeem ua kom nrawm nrawm thiab tej zaum ua rau DTH rauj puas tsuaj.
7. Qhov kawg ntawm lub loosened laum yeeb nkab xov yuav tsum tau them nyob rau hauv thiaj li yuav tiv thaiv lub laum yeeb nkab los ntawm sticking rau pob zeb khib nyiab thiab lwm yam impurities uas yuav poob rau hauv DTH rauj thaum lub sij hawm txuas ntxiv.
