Piv nrog cov tsoos steel laum rods, titanium alloy laum rods muaj tsib qhov zoo: lub teeb yuag, corrosion resistance, ntev lifespan, siab yooj, thiab tsis yog{0}}magnetic zog. Rau tib qhov tshwj xeeb, qhov hnyav ntawm titanium alloy laum pas nrig yog 57% ntawm cov pa laum pas nrig. Qhov no txhais tau hais tias cov cuab yeej laum siv titanium alloy laum pas nrig yog sib dua, thiab kev ua haujlwm drilling tuaj yeem siv qis dua -qib drilling rigs, uas tuaj yeem txuag tau nyiaj ntau txhua hnub thiab txo cov nqi drilling.
Cov qauv rau kev xyaum rods feem ntau suav nrog GB/T 29166-2021 'Steel Drill Rods rau Petroleum thiab Natural Gas Industry', GB/T 20659-2017 'Aluminum Alloy Laum Rods rau Petroleum thiab Natural Gas Industry', Ro SY/S'203 SY/T 7826-2024 'Ob phab ntsa Drill Rods', tab sis cov qauv no tsis npog cov ntaub ntawv titanium alloy.
Lub koom haum ntawm Engineering Materials tau tsim ib pab neeg rau kev txhim kho titanium alloy laum pas nrig qauv. Raws li kev tshawb fawb txog kev tshawb fawb, kev sim kuaj, thiab kev kuaj xyuas hauv teb, pab pawg tau tsim cov ntsiab lus hauv cov qauv, suav nrog cov ntsuas kev qhia tseem ceeb, tsis muaj, cov qauv, cov kev xav tau ntawm kev ua tau zoo, cov txheej txheem xeem, thiab cov cai tshuaj xyuas, thiab tshawb xyuas lawv hauv cov txheej txheem tsim khoom thiab daim ntawv thov kev xeem. Hais txog kev ua tau zoo ntawm cov khoom siv titanium alloy, kev tshuaj xyuas thiab kev suav tau ua rau cov titanium alloys xws li TC4, TA15, thiab TA8. Raws li kev sim ntau cov ntaub ntawv, kev ua tau zoo ntawm titanium alloy laum rods tau npaj tseg, suav nrog kev tawm dag zog, lub zog tensile, hardness, thiab cuam tshuam toughness. Cov ntsuas kev ua tau zoo no tau raug lees paub rau qhov ua tau thiab tsim nyog los ntawm kev tsim khoom lag luam. Hais txog cov txheej txheem kev sim rau titanium alloy laum cov khoom siv, cov txheej txheem kev sim tseem ceeb tau tsim raws li cov xwm txheej hauv tsev thiab cov kev xav tau thiab tau tshawb xyuas tom qab. Rau txoj kev ntsuas, kev tshuaj xyuas, thiab kev kos npe ntawm titanium alloy laum rods, cov lus sib txuas tau tsim thiab txheeb xyuas. Hais txog kev thauj mus los thiab khaws cia ntawm titanium alloy laum rods, cov lus tsim nyog tau tsim thiab tshuaj xyuas raws li cov yam ntxwv ntawm titanium alloy laum rods. GB / T 41343-2022 "Titanium Alloy Laum Rods rau Petroleum thiab Natural Gas Industry" raug tso tawm thiab siv.
Nrog rau Tuam Tshoj txoj kev loj hlob ntawm high -acidity roj thiab roj cov peev txheej thiab kev ua haujlwm ntawm ultra- qhov dej tob tshaj li 8,000 meters, coj PetroChina's Tarim Oilfield thiab Sinopec's Northwest Oilfield ua piv txwv, qhov nruab nrab qhov tob tob tau tshaj 8,000 meters, thiab cov roj thiab roj muaj hydrogen sulfide. Qhov kev pheej hmoo ntawm kev nyab xeeb ntawm steel laum rods tau nce zuj zus, thiab tus nqi txhua hnub ntawm qhov 9,000-meter rig yog 1.5 npaug ntawm 7,000-meter rig. Yog li ntawd, muaj kev sib tw hnyav rau ob qho tib si txo qhov hnyav ntawm txoj hlua xyaum thiab txo cov nqi tsim khoom thaum txhim kho kev ua haujlwm. Tsis tas li ntawd, txoj kev loj hlob thib ob ntawm cov dej qub qub hauv PetroChina's Daqing Oilfield yuav tsum tau siv cov sidetracking thiab qhov rais drilling hauv cov qhov dej qub kom siv tau cov peev txheej uas twb muaj lawm thiab txuag cov nqi kev loj hlob, uas tseem ua rau muaj kev thov tseem ceeb rau titanium alloy laum rods. Kev tsim cov qauv rau titanium alloy laum rods yog cov txiaj ntsig zoo ntawm kev lag luam, vim nws ua kom cov qib zoo ntawm titanium alloy laum rods, txhim kho lawv txoj kev nyab xeeb, txhawb nqa lawv daim ntawv thov, thiab txo cov nqi ntawm cov roj thiab roj.
