DHD Series Dth Dammer Thiab Bit Chaw Tsim Tshuaj Hoobkas Nqe
1) Tsis-Blocking: Peb S-series Down lub qhov rauj yog pov thawj los xyuas kom meej tus nqi qis heev ntawm kev thaiv thaum nws ua haujlwm.
2) Kev ua haujlwm siab: Cov cuab yeej zoo drilling yog nqa nrog lub zog loj ntawm kev cuam tshuam ntau zaus thiab lub zog, yog li ua kom nkag mus sai dua.Piv nrog rau lwm tus, qhov ua tau zoo tuaj yeem txhim kho 10%.
3) Lub neej ua haujlwm ntev: Txhua qhov chaw ntawm DTH rauj thiab cov khoom raug kho los ntawm kev sib txhuam thiab siv tshuab siv zog.Thaum siv hauv qhov tob tob drilling ua haujlwm, nws tuaj yeem ncav cuag 5000 meters lossis ntau dua.
4) Cov nyhuv ntxuav zoo heev: Cov cuab yeej DTH no muaj cov cua tso tawm loj, uas tsim tshwj xeeb rau cov neeg siv dej zoo thiab ua kom nws tshem tawm cov txiav hauv qhov tob tob drilling ua haujlwm.
