5-6 nti Siab Cua Siab DTH Bit

Cov ntawv thov:

Cov khoom siv DTH yog siv dav hauv kev khawb av hauv av, chaw txua zeb, hydraulic thiab Hydro-Power Engineering, kev khawb dej zoo, kev tshawb nrhiav cov ntxhia, kev khawb qhov anchoring, geothermal engineering, Subway excavation, lwm yam kev tsim kho vaj tse. nws muaj qhov zoo ntawm qhov tiaj tiaj, phab ntsa du, qhov nruj ntawm cov pas nrig laum thiab rauj, ywj pheej ntawm qhov siab axial thrust, tsis muaj kev txwv ntawm qhov tob drilling, tus nqi qis ntawm cov khoom siv thiab yooj yim rau kev tswj hwm.

Qhov Zoo ntawm Kev Kub Siab Cua DTH Bit:

Lub neej ntev ntawm lub laum: cov khoom siv hlau, nrog kev siv lub neej ntev dua uas zoo dua li cov khoom zoo sib xws;

Kev Ua Haujlwm Zoo Tshaj Plaws: cov nyees khawm laum yog hnav-resistant, yog li ntawd lub laum tuaj yeem ua kom ntse tas li, yog li txhim kho qhov ceev ntawm qhov drilling.

Qhov ceev ntawm qhov drilling yog ruaj khov: lub ntsis raug khawb thiab txiav kom tawg lub pob zeb.

Kev Ua Tau Zoo: lub pob zeb diamond tshiab muaj kev tiv thaiv kev hnav zoo, kev tiv thaiv txoj kab uas hla zoo thiab tuaj yeem ua rau cov hniav txiav siv tau zoo.

Kev siv ntau yam: kev xyaum ua pov thawj tias lub ntsis no haum rau pob zeb carbonate, limestone, chalk, pob zeb av nplaum, siltstone, sandstone thiab lwm yam mos thiab tawv (9 - qib drillability ntawm pob zeb, pob zeb tawv drilling), piv nrog cov ntsis ib txwm, tshwj xeeb tshaj yog drilling hauv 6-8 qib pob zeb qhov cuam tshuam yog qhov tseem ceeb tshwj xeeb.
