DTH laum cov kav dej ua lub luag haujlwm tseem ceeb hauv DTH drilling - tsis hais txog ntawm daim ntawv thov, pob zeb hom, qhov tob lossis laum rig.Cov yam ntxwv tseem ceeb ntawm cov yeeb nkab zoo drilling yog durability, siab hardness, stability, raug.

Cov yeeb nkab zoo
Hardness thiab hnav tsis kam ua ke alloy stell, muab los ntawm lub teb chaws sab saum toj qib tshwj xeeb steel chaw tsim tshuaj paus.

Tsis muaj kev sib txuas tsis muaj zog
Kev lig kev cai, cov xov thiab kev sib koom ua ke ntawm lub raj thiab cov khoom kawg yog qhov yooj yim.Txhawm rau tiv thaiv qhov teeb meem, peb tau sib txhuam-welded cov pob qij txha kom muaj zog tshaj plaws thiab kho cua sov-kho qhov kawg-thooj rau qhov zoo tshaj plaws durability.

Stability thiab durability xov
Hwm hlau alloy steel ua cov pob qij txha, nruj tswj hwm cov txheej txheem kev kho cua sov thiab cov txheej txheem API xov ua tshuab; peb ua tib zoo mloog rau tag nrho cov ntsiab lus tsis quav ntsej kom ua kom lub neej ntev, kev ruaj ntseg thiab xov ntev.
