Cov yeeb nkab steel nrog tus pin ntawm ib kawg thiab cov yeeb nkab steel nrog lub thawv ntawm lwm qhov kawg ua rau feem ntau ntawm DTH laum yeeb nkab. Lub laum yeeb nkab txoj haujlwm yog xa cov laum me ntsis qhov kev sib hloov torque thiab thrust mus rau lub downhole laum. DTH laum ntsis thiab rauj tuaj yeem tswj tau ua ke los ntawm kev sib txuas ntawm DTH laum yeeb nkab. Rau kev siv sib txawv, cov kab sib txawv yog xav tau. Hauv qhov tseem ceeb, cov cuab yeej DTH me me xav tau cov kav dej me me DTH xyaum thiab rov ua dua. Peb feem ntau muab 50mm, 60mm, 76mm, 89mm, thiab lwm yam. Cov xov ntau ntawm DTH laum kav yog cov qauv API sib txuas xws li 23/8 "API REG xov, 31/2" API REG xov, lossis API IF xov. Tag nrho cov DTH laum kav yog kev sib txhuam welded.
Dab tsi yogDTH laum cov kav dejsiv rau?
DTH (Down-The-Hole) laum kav yuav siv tau nyob rau hauv ntau yam engineering thiab industries. Nov yog qee qhov piv txwv ntawm engineering tej yam kev mob uas DTH laum kav feem ntau ua hauj lwm:
Kev Tshawb Fawb Txog Kev Tshawb Fawb: DTH cov kav dej yog siv dav hauv kev tshawb nrhiav mining. Lawv tau ua haujlwm rau kev rho tawm ntau hom minerals, xws li hlau ores, thee, thiab gemstones. DTH laum kav xa cov cua compressed thiab tig lub zog los tsav lub laum me ntsis, ua rau pob zeb nkag thiab tawg hauv av.
Foundation Engineering: Hauv lub hauv paus engineering, DTH laum kav yog feem ntau siv rau pawg tsav tsheb thiab drilling. Lawv tau ua hauj lwm rau drilling qhov tob hauv paus pits, choj piers, lub hauv paus tsev, nrog rau cov installation ntawm pawg thiab kev txhawb nqa rods.
Dej Drilling: DTH laum kav dej ua lub luag haujlwm tseem ceeb hauv cov dej zoo drilling. Lawv yog siv rau drilling qhov dej, qhov dej kub hauv qab, lossis saib xyuas qhov dej. DTH laum cov kav dej ua kom muaj kev nkag tau sai thiab muaj txiaj ntsig los ntawm cov pob zeb hauv av kom nkag mus rau cov dej hauv av lossis rau kev saib xyuas dej hauv av.
Geotechnical Engineering: DTH laum kav yog siv rau cov av thiab pob zeb sampling thiab kuaj hauv geotechnical engineering. Lawv tuaj yeem siv rau kev tshawb nrhiav av, kev kuaj pob zeb, thiab kev tshawb fawb geological.
Environmental Site Assessment: Kev ntsuam xyuas qhov chaw ib puag ncig suav nrog kev tshawb xyuas thiab saib xyuas cov av thiab dej hauv av. DTH laum cov kav dej tuaj yeem siv rau kev saib xyuas qhov dej txhawm rau sau cov av thiab dej hauv av rau kev tshuaj xyuas thiab kuaj.
Kev Tshawb Fawb Txog Geological: DTH laum cov kav dej pom siv dav hauv kev tshawb nrhiav geological. Lawv ua hauj lwm rau prospecting mineral deposits, roj thiab roj reservoirs, thiab underground geological qauv. DTH laum cov kav dej tuaj yeem nkag mus tob rau hauv cov txheej txheem geological, tso cai rau cov ntaub ntawv geological thiab cov qauv sau.
Cov yam ntxwv ntawm DTH laum kav
Lub laum me ntsis yog siv los tsa, txo qis, los yog tig lub qhov hauv qab lub cuab yeej thaum drilling av nkos raug xa mus rau lub laum me ntsis ntawm lub laum yeeb nkab. DTH laum kav yuav tsum muaj peev xwm tiv taus siab ntawm sab hauv thiab sab nraud, nrog rau deformation, khoov, thiab kev co. Nyob rau hauv cov txheej txheem ntawm extracting thiab refining roj thiab roj, DTH laum kav tej zaum yuav siv ntau tshaj ib zaug. DTH laum kav yog tsim los ntawm kev ua ob qho tib si steel yeeb nkab thiab lub teeb steel yeeb nkab. Sab nrauv ntawm lub teeb yeeb nkab yog thawj zaug khoov rau sab hauv thaum lub sij hawm thickening ntawm cov yeeb nkab steel txheej txheem kom thicken cov yeeb nkab phab ntsa. Qhov thib ob, tooj liab lub zog tuaj yeem nce los ntawm threading thiab plating. Cov yeeb nkab yog ces welded tom qab ib qho kev ntsuam xyuas tsis muaj kev puas tsuaj. Txhawm rau tshem tawm cov welding residual siab, cov yeeb nkab yuav tom qab vuam kev kho cua sov thiab kev kho vuam kawg. Lwm qhov kev ntsuam xyuas, xws li hardness, siab, thiab kev kuaj tsis muaj kev puas tsuaj, yog ua los ntawm cov kav dej zaum kawg ua ntej nws yuav pleev xim thiab ntim. Cov ntaub ntawv zoo yog siv los tsim cov kav dej DTH laum, thiab nws tau dhau los ua spectroscopic, cuam tshuam, thiab ntsuas tensile. Nitrogen yog siv los kho qhov chaw. Nws kuj yog ib qho yooj yim los lis vim yog cov xov uas muaj zog.
