Dth xyaum cov kav dej, zoo li cov cuab yeej indestructible, tiag tiag muaj "lifespan"? Raws li yog tias lawv tuaj yeem ua haujlwm tsis tu ncua, peb ib txwm pom cov cuab yeej drilling ua tus txiv neej tsis muaj zog. Qhov tseeb, xyaum cov kav dej kuj yuav tsum tau hloov ntau zaus, ntau npaum li koj nyiam cov khau ntaub. Cia peb tham txog cov ntsiab lus txaus nyiam niaj hnub no: yuav tsum tau hloov cov kav dej DTH ntau npaum li cas?
"Ua Haujlwm Diary" ntawm DTH Drill Rods
Cia peb tham txog qhov chaw ua haujlwm ntawm DTH laum kav ua ntej. DTH laum kav dej tsis yog cov khoom siv ua haujlwm txhua hnub. Kaum los yog ntau pua metres nqes, lawv yuav tsum sib tham txog cov pob zeb tawv tawv, cov txheej txheem geological tsis sib xws, thiab tsis pom kev siab thiab kev sib txhuam. Koj tuaj yeem xav txog tias nws txoj haujlwm zoo li tus miner, khawb hauv av txhua hnub, tawm hws ntau heev. Txawm hais tias nws tau tsim los ntawm cov hlau tsis muaj zog, nrog rau lub sijhawm hnav thiab tsim kua muag tsis tuaj yeem zam.
Kev hnav ntawm DTHlaum cov kav dejfeem ntau yog concentrated nyob rau hauv qhov kev twb kev txuas qhov chaw, threads, thiab ncej nws tus kheej. Lub sijhawm ntev, cov chaw no muaj kev sib txhuam, siab, thiab kev vibration; Yog li ntawd, hnav, tawg, thiab txawm tawg yuav ua rau muaj kev phom sij. Ib yam li koj cov ntaub ntawv xov tooj yuav hnav tom qab siv sijhawm ntev, cov yeeb nkab laum tsis tuaj yeem nyob "hluas" mus ib txhis.
Kev cuam tshuam ntawm kev siv ib puag ncig
Yog li, ntau npaum li cas yuav tsum tau hloov DTH laum yeeb nkab? Tsis muaj lus teb rau lo lus nug no, vim nws nyob ntawm ntau yam. Thawj qhov cuam tshuam rau ib puag ncig. Cov yeeb nkab laum hauv cov tawv granite yuav hnav sai dua li hauv cov av me me. Khiav ntawm txoj kev asphalt thiab ntawm ntug hiav txwv zoo li khiav ntawm qhov sib txawv hnav-tus nqi rau cov hauv qab.
Tsis tas li ntawd, yog hais tias cov geological tej yam kev mob uas koj nyob rau hauv yog complex, xws li ib tug loj tus naj npawb ntawm cov kab nrib pleb, faults los yog unstable pob zeb formations, lub laum yeeb nkab yuav yooj yim dua puas. Hauv qhov xwm txheej no, lub laum yeeb nkab hloov zaus tuaj ntau dua.
Qhov tseem ceeb ntawm cov cwj pwm ua haujlwm
Ntxiv nrog rau kev siv ib puag ncig, cov cwj pwm kev ua haujlwm kuj yog ib qho tseem ceeb cuam tshuam rau lub neej ntawm cov yeeb nkab laum. Lub neej kev pab cuam ntawm lub laum yeeb nkab yuav ib txwm ntev dua yog tias tus neeg teb xov tooj tau paub txog thiab paub yuav ua li cas txo qis qhov hnav ntawm lub laum yeeb nkab los ntawm kev kho qhov drilling siab thiab ceev. Zoo li tsav tsheb, tus neeg tsav tsheb txawj ntse tuaj yeem khaws lub tsheb kom zoo; tus neeg tshiab tuaj yeem hloov cov log tsheb ntau zaus.
Yuav txiav txim seb puas yuav hloov lub laum yeeb nkab?
Txij li thaum tsis muaj lub voj voog hloov kho rau DTH laum yeeb nkab, peb yuav txiav txim li cas seb nws puas yog lub sijhawm "tso tseg"? Qhov tseeb, muaj lwm yam qhia tsim nyog pom. Qhov feem ntau natural qhia yog thawj xov hnav. Yog tias cov xov tau pom tias tau hnav tiaj tus los yog tawg, lub laum yeeb nkab yuav tsum tau hloov. Qhov thib ob, cov yeeb nkab laum no yuav tsum tau so haujlwm yog tias nws pib qhia meej deformation thaum siv-uas yog, khoov, twisting, lossis pas nrig lub cev tawg.
Tsis tas li ntawd, yog tias qhov kev ua tau zoo ntawm qhov drilling tau txo qis, xws li kev sib tsoo qeeb qeeb, nce kev vibration thaum lub sij hawm drilling, thiab cov pa tawm ntawm qhov kev sib txuas ntawm cov yeeb nkab laum, cov no yog tag nrho cov tshwm sim ntawm hnyav hnyav ntawm lub laum yeeb nkab, thiab nws raug nquahu kom hloov nws. hauv lub sijhawm.
Common Drill Pipe Replacement Cycle
Txawm hais tias kev siv ib puag ncig thiab kev ua haujlwm cuam tshuam rau lub voj voog hloov, feem ntau DTH laum yeeb nkab muaj kev pab cuam lub neej ntawm 5, 000 meters thiab 15, 000 meters, uas yog, tom qab drilling mus rau qhov tob ntawm 5, 000 txog 15,000 meters, nws yog lub sij hawm los txiav txim siab hloov nws. Yog tias koj tab tom khawb hauv cov pob zeb nyuaj, nws raug nquahu kom kuaj xyuas qhov xwm txheej ntawm cov yeeb nkab laum txhua 5, 000 meters. Txawm hais tias lub laum yeeb nkab txoj kev pab cuam lub neej yuav ua tau me ntsis ntev nyob rau hauv heev soft formations, tsis tu ncua kev ntsuam xyuas yog tseem tsim nyog kiag li.
Kev tu thiab tu tsis tu ncua
Tau kawg, ua kom DTH laum yeeb nkab "nyob ntev", nws tsis txaus los hloov nws. Ib yam li qhov tseem ceeb yog kev saib xyuas thiab saib xyuas tsis tu ncua. Cov xov, pob qij txha, thiab ncej yuav tsum tau soj ntsuam zoo tom qab txhua qhov kev siv yeeb nkab siv los tshem tawm cov av thiab roj ntawm qhov chaw kom tiv thaiv corrosion thiab hnav ntxiv. Tib lub sijhawm roj cov xov kom txo qis kev sib txhuam rau kev siv tom ntej. Cov ntsiab lus me me no yuav txuas ntxiv lub neej kev pab cuam ntawm lub laum yeeb nkab.
Tau hais ntau dhau lawm, tej zaum koj yuav pom tias DTH laum yeeb nkab hloov lub voj voog tsis yog tus lej tas li tab sis yuav tsum tau hloov pauv hloov pauv raws li cov xwm txheej tiag tiag. Txawm hais tias lub laum yeeb nkab yog ua los ntawm cov hlau muaj zog, nws muaj "kev txwv". Kev tshuaj xyuas tsis tu ncua, kev siv tsim nyog, thiab kev hloov pauv raws sijhawm tuaj yeem ua kom muaj kev vam meej ntawm kev ua haujlwm drilling thiab zam kev pheej hmoo tsis tsim nyog.
Nco ntsoov tias qhov zoo tshaj plaws DTH laum yeeb nkab ntawm qhov chaw drilling kuj xav tau "so" thiab "kev kuaj lub cev"! Kuv vam tias cov kev sib koom me me no yuav pab tau rau koj, thiab kuv tos ntsoov yuav tham nrog koj lwm zaus txog cov ncauj lus nthuav dav txog cov cuab yeej drilling.
Cov Lus Nug Nquag (FAQ)
Yuav tsum muaj pes tsawg dth laum kav rau drilling?
Tus naj npawb ntawm cov kav dej hauv qab-qhov-qhov xav tau rau qhov drilling yog nyob ntawm qhov tob ntawm lub qhov uas tau drilled, tab sis feem ntau, ib tug loj tus naj npawb ntawm cov tho yeeb nkab yuav tsum tau mus txog qhov tob tob, raws li txhua qhov yeeb nkab seem feem ntau tsuas yog nyob ib ncig ntawm. 30 ko taw ntev, txhais tau tias ntau ntu yuav tsum tau txuas ua ke kom ncav cuag qhov tob; qhov txuas txuas ntawm cov kav dej no yog hu ua "drill string."
Cov ntsiab lus tseem ceeb ntawm cov kav dej laum:
Feem ntau yog li ntawm 27 mus rau 32 ko taw, txhua tus neeg tho yeeb nkab yog
Ntau cov yeeb nkab laum yog ua ke ua ke siv cov cuab yeej sib txuas kom nqis mus ntxiv.
Kev hloov pauv xav tau: Tag nrho qhov tob ntawm lub qhov uas tau drilled yuav txiav txim seb cov kav dej xav tau.
