Kev ua tiav ntawm kev lag luam roj thiab roj drilling yuav tsum muaj ob yam tseem ceeb: lublaum dab tshosthiab covlaum cev.
Drill Pipe vs. Drill Collar txhais
Lub dab tshos yog ib qho hnyav, tuab-walled, thiab nruj yeeb nkab uas txuas ncaj qha saum lub laum me ntsis. Cov yeeb nkab drilling yog qhov ntev, hollow, thiab lub teeb yuag tubular tivthaiv uas xa cov hluav taws xob sib hloov thiab cov dej drilling los ntawm qhov chaw mus rau qhov laum me ntsis.
Qhov sib txawv ntawm cov dab tshos laum thiab cov yeeb nkab laum
Qhov sib txawv tseem ceeb muaj feem rau lawv qhov ntev, qhov hnyav, cov khoom siv, thiab kev siv.
(1) Cov dab tshos feem ntau luv dua thiab tuab dua cov kav dej, nrog lub taub loj dua thiab hnyav dua. Qhov hnyav ntxiv thiab rigidity yog qhov tseem ceeb rau kev ua kom muaj qhov hnyav ntawm qhov me me thiab tswj kev tswj kev taw qhia thaum lub sijhawm drilling txheej txheem.
Hloov pauv, cov kav dej drilling yog ntev dua, nyias, thiab sib dua, ua kom muaj zog sib kis tau zoo thiab cov dej ntws thoob plaws tag nrho cov txheej txheem drilling.
(2) Khoom siv
Laum dab tshos feem ntau yog ua los ntawm cov hlau muaj zog, uas muab qhov tsim nyog qhov hnyav thiab ua haujlwm kom tiv taus cov xwm txheej huab cua uas tau ntsib thaum lub sijhawm drilling. Cov hlau no nyob rau hauv ntau qhov kub-kho lossis raug rau kev tsim khoom tshwj xeeb los txhim kho lawv cov kev sib koom siab, hnav kev cuam tshuam, thiab kev tawm tsam.
Lawv kuj tseem yuav raug tsim los siv tungsten carbide, cov khoom siv tawv thiab hnav-tiv taus uas tuaj yeem ua haujlwm ntawm nws lub neej ntev thiab ua tiav. Cov alloys tshwj xeeb, piv txwv li, cov uas muaj npib tsib xee, chromium, los yog molybdenum, kuj tseem siv rau hauv lawv txoj kev loj hlob los hais txog qhov tseem ceeb ntawm kev ua haujlwm, xws li muaj zog tiv thaiv corrosion los yog txhim kho tensile zog.
Laum cov kav dej, tom qab ntawd dua, feem ntau yog ua los ntawm cov hlau sib xyaw, uas muaj qhov sib npaug ntawm kev sib koom ua ke, hloov tau, thiab cov khoom hnyav. Cov hlau alloy no yog tsim los tiv thaiv cov khoom hnyav thiab kev ntxhov siab thaum lub sij hawm drilling txheej txheem, kom ntseeg tau tias muaj zog xa hluav taws xob thiab cov dej ntws.
Hauv qee qhov kev siv, cov khoom siv txhuas lossis cov khoom sib xyaw siv tau. Cov kav dej txhuas tuaj yeem muab qhov hnyav txo, uas tuaj yeem ua tau zoo hauv qee qhov xwm txheej drilling, xws li kev ua haujlwm hauv dej tob lossis qhov dej sib txawv heev. Cov ntaub ntawv sib xyaw, xws li carbon fiber-reinforced polymers, kuj tau txais traction hauv kev lag luam vim lawv lub zog-rau-hnyav piv thiab tiv thaiv corrosion.
(3) Daim ntawv thov
Lub laum dab tshos qhov tseem ceeb ntawm qhov kev ua tau zoo ntawm qhov drilling yog nws lub peev xwm los muab qhov tsim nyog qhov hnyav ntawm qhov me ntsis, uas yog qhov tseem ceeb rau kev ua haujlwm zoo. Kev xa tawm qhov hnyav ntawm txoj hlua laum mus rau me ntsis pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm
Tsis tas li ntawd, nws cov nyhuv stabilizing pab txhawb kev txhim kho qhov tu, vim qhov txo qhov sib txawv ntawm qhov borehole thiab kev ruaj ntseg ntxiv pab kom ntseeg tau tias cov av nkos thiab cov txiav tau zoo rov qab mus rau saum npoo. Qhov no, nyob rau hauv lem, txhim khu tag nrho cov drilling efficiency thiab txo cov kev pheej hmoo ntawm daig yeeb nkab los yog lwm yam teeb meem kev ua hauj lwm.
Lub laum yeeb nkab qhov kev ua tau zoo yog qhov tseem ceeb hauv nws txoj kev siv thoob plaws hauv kev lag luam roj thiab roj. lawv tau tsim los ua kom haum rau ntau yam ntawm cov txheej txheem drilling thiab cov kev xav tau ntawm qhov dej. Lawv lub peev xwm xa hluav taws xob thiab xa cov dej drilling ua rau lawv qhov tseem ceeb rau ob qho tib si ntsug thiab qhov sib txawv ntawm qhov zoo drilling, nrog rau ntau hom kev ua haujlwm drilling, xws li kev tshawb nrhiav, kev tsim kho, thiab kev ua haujlwm.
Lawv muaj cov ntaub ntawv sib txawv thiab kev teeb tsa tso cai rau cov kev daws teeb meem los daws cov teeb meem tshwj xeeb, xws li qhov hnyav txo hauv qhov chaw sib sib zog nqus dej lossis txhim kho corrosion kuj nyob rau hauv qhov hnyav downhole.
Yog tias koj xav yuav ob qho tib si, koj tuaj yeem tau txais lawv ntawm Vigor, Vigor yuav muab kev daws teeb meem rau koj, Thov hu rau peb ntawminfo@vigorpetroleum.com.
