Auger drilling yog hais txog ib yam ntawm cov teb drilling. Lo lus "ntsia hlau" nws tus kheej los ntawm lo lus "Schnecke", uas nyob rau hauv German txhais tau tias ntsia hlau, curl, qwj.
Txoj haujlwm ntawm kev ua haujlwm
hom drilling no txawv ntawm lwm hom, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm no, cov pob zeb puas raug tshem tawm thiab thauj mus los ntawm qhov dej tsis yog los ntawm kev khiav ntawm tus neeg saib xyuas, tab sis vim yog kev sib hloov ntawm lub qhov dej. column.
Auger drilling yog dav heev, yog ib txoj hauv kev siv rau kev drilling qhov ntiav hauv cov pob zeb mos los yog tsis sib xyaw. Txoj kev no yooj yim rau kev ua haujlwm hauv pebble pob zeb. Nws kuj tseem siv dav hauv kev tshawb nrhiav seismic, blasthole txoj kev loj hlob, kev tshawb fawb hydrogeological engineering, kev tshawb fawb geological, thiab kev tshawb nrhiav ntxhia.
Drilling technology
Drilling augers loosen thiab crush lub pob zeb thaum lub sijhawm ua haujlwm, thiab tom qab ntawd txav cov khoom tsim tawm mus rau lub qhov dej ntawm qhov tshwj xeeb ntsia hlau conveyor. Kev siv tshuab ua haujlwm suav nrog peb lub ntsiab lus tseem ceeb. Cov no yog: cov txheej txheem ntawm kev ua kom txias lub cuab yeej koom nrog kev puas tsuaj ntawm pob zeb, thauj cov khoom ntawm kev puas tsuaj rau saum npoo thiab ntxiv dag zog rau cov phab ntsa ntawm qhov tshwm sim zoo nrog cov pob zeb lifted.
Auger drilling yog ua tiav nrog cov cuab yeej drilling. Muaj peb hom cuab yeej cuab tam. Drilling khoom yog ib kem ntawm cov pa augers nrog ib tug chisel, ib tug magazine auger nrog ib tug crown, zoo tib yam thiab hollow kab nrog ib tug tshem tau chisel thiab ib tug tshem tau core receiver.
Dav siv los ua haujlwm nrog cov pob zeb xoob ob-lossis peb-hniav chisel nrog tiaj tus lossis kauv hniav. Thaum auger drilling yog ua nyob rau hauv nruab nrab hard formations, yuav tsum tau ntau dua hnav kuj, yog li ib tug rounded carbide loaded me ntsis yog siv.
High-tech tshwj xeeb kev teeb tsa yog siv thaum ua haujlwm. Qhov ceev ntawm drilling yog qhov loj, yog li cov kev xav tau rau kev teeb tsa yog kev txav mus los thiab kev thauj mus los siab. Kev teeb tsa yog tsim los nqa tau lossis nqa tus kheej.
Lub ntsiab zoo ntawm auger drilling yog qhov tsis tuaj yeem kho tus kheej ntawm cov phab ntsa ntawm lub qhov dej los ntawm cov pob zeb puas thaum nws tau nqa nrog cov augers, zoo li nws yog, "rubbed" thiab tsim cov nyhuv. ntawm ib hom plastering.
Nco ntsoov tias cov txheej txheem no yog kev siv thev naus laus zis, tab sis tib lub sijhawm yooj yim heev hauv cov ntsiab lus ntawm cov koom haum, cov txheej txheem ntawm kev ua haujlwm hauv av, uas txo qis kev pheej hmoo ntawm kev tawg thaum lub sijhawm ua haujlwm. Auger drilling tauyuav luag txhua lub sijhawm, tsis hais lub sijhawm xyoo twg. Nyob rau tib lub sijhawm, deformation deformation yog qhov tseem ceeb, uas tseem ceeb heev thaum ua haujlwm hauv kev tsheb ciav hlau thiab txoj kev, cov tsev thiab cov khoom siv hluav taws xob.
Qhov pom tau zoo ntawm kev ua haujlwm yog qhov nrawm nrawm, yooj yim thiab kev puas tsuaj me me rau cov vaj tse thiab ib puag ncig.
Cov kws tshaj lij los ntawm thoob plaws lub ntiaj teb nco ntsoov qhov kev txaus siab tas li ntawm txoj kev drilling no thiab kwv yees qhov kev cia siab zoo rau nws txoj kev loj hlob.
