Drill Bit Rau Dej Drilling

 

 

Qhov tsim nyog ntawm pob zeb muaj pes tsawg leeg rau kev siv Drill Bit For Water Well Drilling nyob ntawm ntau yam, nrog rau cov hardness thiab abrasiveness ntawm pob zeb. DTH drilling yog ib txoj hauv kev uas feem ntau siv hauv kev khawb av, kev tsim kho, thiab kev tsim cov quarrying los tho qhov rau hauv pob zeb rau ntau lub hom phiaj, xws li blasting, tshawb nrhiav, lossis kev ua haujlwm hauv paus.

 

 

Feem ntau, DTH drilling yog qhov zoo tshaj plaws ntawm cov pob zeb nyuaj thiab muaj peev xwm. Qhov tsim nyog ntawm pob zeb compositions yuav categorized raws li nram no:

 

Hard Rocks:

Granite: Granite yog ib lub pob zeb tawv heev thiab ntom ntom ntom uas haum rau DTH drilling.
Basalt: Basalt yog lwm lub pob zeb nyuaj uas tuaj yeem drilled zoo siv DTH txoj kev.
Gneiss: Gneiss yog lub pob zeb metamorphic nrog ntau theem ntawm hardness, tab sis feem ntau nws tuaj yeem drilled nrog Drill Bit For Water Well Drilling.

Medium-Hard Rocks:

Sandstone: Sandstone sib txawv hauv qhov nyuaj, tab sis feem ntau hom tuaj yeem raug laum nrog Drill Bit For Water Well Drilling.
Limestone: Limestone tuaj yeem nyob ntawm qhov muag muag mus rau qhov nyuaj, tab sis muaj ntau yam tsim nyog rau DTH drilling.
Shale: Shale feem ntau softer thiab tuaj yeem drilled nrog Drill Bit For Water Well Drilling, txawm hais tias nws yuav xav tau kev sib txawv drilling vim nws nyiam tawg.

Soft Rocks:

Av nplaum thiab Sedimentary pob zeb: Cov pob zeb mos zoo li av nplaum, av nkos, thiab qee hom pob zeb sedimentary yuav tsis xav tau ib lub Drill Bit For Water Well Drilling, vim lawv tuaj yeem drilled nrog me me.

Abrasive pob zeb:

Pob zeb nrog cov khoom sib tsoo, xws li quartz lossis flint, tuaj yeem hnav lub laum me ntsis sai dua. Hauv cov xwm txheej zoo li no, nws yog ib qho tseem ceeb uas yuav tsum siv cov khoom zoo, puas-resistant me ntsis.
