2. Cov cuab yeej laum yuav tsum tsis txhob muab qis rau hauv lub qhov raws li hauv qab no:
ib. Qhov ib sab coj ntawm lub laum yeeb nkab txoj kab uas hla mus txog 2 hli los yog cov khaub ncaws hnav mus txog 3 hli, thiab cov dabtsi yog khoov nyob rau hauv ib qhov ntev ntawm ib 'meter' tshaj 1 hli;
b. Core tube hnav tshaj 1/3 ntawm phab ntsa thickness thiab khoov tshaj 0.75mm ib meter ntev;
c. Cov cuab yeej laum muaj qhov tawg me me;
d. Cov ntsia hlau xov yog hnav hnyav, xoob lossis muaj qhov pom tseeb deformation;
e. Cov yeeb nkab khoov thiab cov yeeb nkab tseem ceeb yuav tsum ncaj nraim nrog cov yeeb nkab ncaj, thiab nws yog nruj me ntsis txwv tsis pub khob nrog lub sledgehammer.
3. Master tsim nyog me ntsis siab, thiab tsis txhob blindly pressurize drilling.
4. Thaum screwing thiab unloading drilling cuab yeej, nws yog nruj me ntsis txwv tsis pub mus khob lub laum yeeb nkab thiab nws cov kev sib koom tes nrog ib tug sledgehammer.
5. Thaum lub sij hawm rotary tsis kam thaum lub sij hawm reaming los yog drilling loj heev, nws tsis pub tsav los ntawm kev quab yuam.
