5-6 nti siab cua siab DTH ntsis
Daim ntawv thov:
DTH laum cov khoom siv dav siv hauv cov mining hauv av, quarries, hydraulic thiab Hydro-Power Engineering, dej zoo drilling, Mineral tshawb nrhiav, anchoring qhov drilling, geothermal engineering, Subway excavation, lwm yam engineering. nws muaj qhov zoo ntawm qhov siab flatness, du lub qhov phab ntsa, siab nruj ntawm laum pas nrig thiab rauj, ywj siab ntawm siab axial thrust, tsis muaj kev txwv ntawm qhov tob drilling, tsis tshua muaj nqi ntawm cov cuab yeej thiab yooj yim los tswj.
Qhov zoo ntawm Cov Cua Kub Siab DTH Bit:
Lub neej ntev ntawm kev xyaum: cov khoom siv alloy, nrog kev siv lub neej ntev dua uas zoo dua li cov khoom zoo sib xws;
High Drilling Efficiency: lub laum nyees khawm yog hnav-resistant, yog li ntawd lub laum yuav yeej ib txwm ua kom ntse, yog li zoo heev txhim kho qhov ceev ntawm lub drilling.
Lub drilling ceev yog ruaj khov: me ntsis yog scraped thiab txiav kom tawg lub pob zeb.
Kev ua tau zoo: Lub Pob Zeb Diamond Tshiab muaj zog hnav tsis kam, txoj kab uas hla zoo tiv thaiv thiab tuaj yeem ua rau cov hniav txiav siv tau zoo.
Kev siv ntau yam: kev xyaum ua pov thawj tias qhov me me yog haum rau carbonate pob zeb, limestone, chalk, av nplaum pob zeb, siltstone, sandstone thiab lwm yam mos thiab tawv (9 - qib drillability ntawm pob zeb, hard pob zeb drilling), piv nrog ib txwm me ntsis, tshwj xeeb tshaj yog drilling hauv 6- 8 qib pob zeb cov nyhuv tseem ceeb tshwj xeeb.
