Qhov zoo ntawm DThers tsuas yog suav nrog cov hauv qab no:
Siv tau zoo heev: DThers muaj siab drilling efficiency, tshwj xeeb tshaj yog nyob rau hauv lub pob zeb nyuaj thiab tawv pob zeb tawv. Lub drilling ceev yog ob peb mus rauzens ntawm lub sij hawm siab dua li ntawd ntawm dog dig teb drooting txoj kev. Piv txwv li, hauv silicified limestone nrog ntsuas ntawm 7 txog 8, lub sijhawm nkag mus tau ncav cuag 20 mus rau ib qho chaw ua haujlwm nruab nrab ib zaug yog ntau tshaj 100 meters.
Ntev Laum Lub Neej: Thaum siv Rauj Rauj rau Drilling, tho lub neej yog qhov txuas ntxiv. Piv txwv li, pob txha hniav laum me ntsis tuaj yeem tho 50 meters hauv cov nyom granite thiab 1000 meters hauv limestone.
Cov kev xav tau qis dua: Lub zog drilling tau xav tau rau dth rauj drilling yog tsawg. Piv txwv li, lub zog drilling rau cov rauv taws nrog cov menyuam lub cheeb tsam ntawm 171kn, thaum lub dth rauj tsuas yog xav tau 13 txog 18kn to ua tiav cov nyhuv drilling zoo. Qhov no tsis tsuas yog txhim kho kev ntxhov siab ntawm cov yeeb nkab laum, tab sis kuj tseem txo qhov kev hloov pauv torque, paving txoj kev rau drilling loj-uas cov taub dej loj (qhov).
Cov nyuab siab tiv thaiv zoo: Vim tias qhov qis drilling thiab footage, dth rauj drilling muaj qhov ua tau zoo anti-deflection cov nyhuv. Nyob rau hauv ib txwm muaj xwm txheej, lub qhov feflection tau tswj tsis pub dhau cov<1º/100m.
Cov hmoov nplej ceev ceev ceev: thaum lub dth rauj yog khawb, tsis muaj hydrostatic sab hauv lub qhov, thiab tsis muaj txhaws thiab puas rau cov aquifer.
Muaj zog hloov tau: DT rauj yog qhov tsim nyog rau drilling qhov ntawm ntau yam specifications, muaj cov khoom siv zoo, thiab tuaj yeem siv hauv ntau txoj haujlwm.
