DTH (Down-The-Hole) drilling thiab rotary drilling yog ob txoj hauv kev siv hauv kev lag luam drilling, txhua tus muaj nws cov yam ntxwv thiab kev siv. Nov yog qhov sib txawv tseem ceeb ntawm DTH thiab rotary drilling:
1. Drilling Mechanism:
DTH Drilling (Down-The-Hole):
Mechanism:DTH drilling muaj ib tug rauj haum nrog ib tug xyaum me ntsis uas ntaus lub pob zeb nyob rau hauv qab ntawm lub qhov. Cov cua compressed yog siv los tsav lub rauj thiab tshem tawm cov txiav tawm ntawm lub qhov.
Daim ntawv thov:DTH drilling yog zoo heev nyob rau hauv cov pob zeb nyuaj formations thiab yog feem ntau siv nyob rau hauv mining, quarrying, kev tsim kho, thiab dej zoo drilling.
Rotary Drilling:
Mechanism:Rotary drilling muaj xws li ib tug rotating laum me ntsis txuas mus rau qhov kawg ntawm ib txoj hlua xyaum. Lub laum me ntsis grinds thiab txiav lub pob zeb raws li nws tig, thiab av nkos los yog lwm yam drilling kua yog circulated rau hauv lub laum yeeb nkab kom yaug tawm cuttings thiab txias me ntsis.
Daim ntawv thov:Rotary drilling yog ntau yam thiab siv nyob rau hauv ntau yam geological formations, nrog rau cov av mos, av nplaum, xuab zeb, thiab pob zeb. Nws yog feem ntau siv rau hauv kev tshawb nrhiav geotechnical, kev tshawb nrhiav roj thiab roj, thiab dej zoo drilling.
2. Drilling ceev thiab nkag mus:
DTH Drilling:
DTH drilling nyiam muab cov kev nkag siab ntau dua hauv cov pob zeb nyuaj vim yog qhov cuam tshuam rau rauj, uas ua rau lub pob zeb tawg tau zoo.
Nws yog qhov tshwj xeeb tshaj yog tsim rau cov ntawv thov uas qhov drilling ceev thiab nkag mus yog qhov tseem ceeb, xws li hauv mining rau ore extraction.
Rotary Drilling:
Rotary drilling tuaj yeem ua qeeb qeeb hauv cov pob zeb nyuaj piv rau DTH drilling vim nws tso siab rau qhov kev sib tsoo me ntsis es tsis cuam tshuam rau kev tawg pob zeb.
Txawm li cas los xij, rotary drilling feem ntau yog nrawm dua hauv cov qauv softer thiab feem ntau xaiv rau nws txoj kev siv ntau yam hauv kev tuav ntau yam hauv av.
3. Drilling qhov tob:
DTH Drilling:
DTH drilling yog siv nyob rau hauv qhov ntiav mus rau nruab nrab qhov tob, tshwj xeeb tshaj yog nyob rau hauv cov pob zeb nyuaj formations.
Nws tuaj yeem ntsib cov teeb meem hauv kev sib sib zog nqus drilling vim qhov kev txwv ntawm rauj efficiency thiab tshem tawm cov txiav.
Rotary Drilling:
Rotary drilling txoj kev, xws li av nkos teb los yog cua rotary, muaj peev xwm ntawm drilling mus rau ntau dua qhov tob.
Lawv feem ntau yog siv rau hauv qhov sib sib zog nqus borehole drilling rau geothermal qhov dej, kev tshawb nrhiav roj thiab roj, thiab dej qhov dej.
4. Qhov taub:
DTH Drilling:
DTH drilling tuaj yeem tsim qhov me me-inch, ua rau nws haum rau cov ntawv thov uas yuav tsum tau ua kom raug.
Rotary Drilling:
Rotary drilling txoj kev tuaj yeem tsim ntau yam ntawm lub qhov taub, los ntawm cov qhov me me rau qhov loj-ntev hauv paus pawg.
Ob txoj kev DTH thiab rotary drilling txoj kev muaj lawv qhov zoo thiab raug xaiv raws li qhov tshwj xeeb geological tej yam kev mob, xav tau lub qhov taub, drilling qhov tob, thiab lub hom phiaj project. Kev xaiv ntawm ob txoj hauv kev yog nyob ntawm qhov kev xav tau tshwj xeeb thiab cov kws tshaj lij ntawm cov kws tshaj lij drilling koom nrog.
