Titanium rods rau roj drilling: daim ntawv thov nyob rau hauv huab ib puag ncig
Nyob rau hauv toj roob hauv pes ntawm cov roj drilling, qhov tob tob, ultra{0}} qhov tob tob, siab - cov dej sulfur, thiab qhov tob - dej hiav txwv sawv zoo li plaub qhov siab tshaj plaws ua ntej kev lag luam. Cov khoom siv drilling tsoos feem ntau ua tsis tiav hauv qhov chaw huab cua no vim tsis muaj zog txaus, corrosion hnyav, lossis cuam tshuam sib nqus. Qhov tshwm sim ntawm titanium rods, txawm li cas los xij, zoo li kev txhaj tshuaj "Iron Man" noob rau hauv cov khoom siv drilling, rov hais dua cov kev txwv ntawm kev khawb hauv qhov chaw huab cua nrog nws peb qhov zoo: hnav, hnav tsis kam, thiab tsis yog - cov khoom sib nqus.
Lub teeb yuag: tawg los ntawm hnyav hnyav nrog lub teeb yuag tsim, xauv qhov tob zoo muaj peev xwm
Thaum drilling qhov tob tshaj 8000 meters, qhov hnyav ntawm cov yeeb nkab laum ua ib qho tseem ceeb txwv kev ua haujlwm drilling. Ib txwm siv cov yeeb nkab steel laum, vim lawv qhov siab ceev, yuav tsum muaj ntau ntau tons ntawm kev thauj khoom rau txhua puas meters ntawm kev txuas ntxiv, ua rau muaj kev nce siab hauv kev siv zog drilling rig thiab cov khoom siv nrawm dua. Titanium rods, nrog ib qhov ceev tsuas yog 57% ntawm cov hlau, tuaj yeem txo qhov hnyav ntawm cov kav dej laum los ntawm ntau dua 30% thaum tuav tib lub zog. Cov yam ntxwv no muaj cov txiaj ntsig tseem ceeb hauv ultra- qhov tob tob drilling: noj ib qho ultra- qhov dej tob ua piv txwv, tom qab hloov mus rau titanium alloy laum kav, qhov drilling rig torque yuav tsum tau txo qis los ntawm 40%, qhov sib sib zog nqus load poob los ntawm 25%, qhov kev ua haujlwm txhua hnub drilling tau nce los ntawm 15%, thiab cov cuab yeej tsis ua hauj lwm tus nqi txo los ntawm 3%. Lub teeb yuag tsim tsis tsuas yog ncua lub neej ntawm txoj hlua xyaum xwb tab sis kuj ua rau "10,000-meter tob tob" qhov tseeb.
Corrosion Resistance: Conquering lub siab -Sulfur Forbidden Zone nrog "Toughness"
High-sulfur oil and gas fields yog "lub hav ntawm kev tuag" nyob rau hauv lub drilling teb. Hydrogen sulfide thiab chloride ions tsim ib qho chaw corrosive heev nyob rau hauv qhov kub thiab txias. Traditional nickel-based alloy pipes have a lifespan of less than 3 years under these conditions, while titanium rods, with their dense oxide film, can withstand extreme environments with hydrogen sulfide partial pressures exceeding 10 MPa. Cov ntaub ntawv ntsuas tseeb los ntawm qhov siab - cov pa roj sulfur qhia tau tias tom qab 5 xyoo ntawm kev ua haujlwm tas mus li, qhov corrosion ntawm phab ntsa sab hauv ntawm titanium alloy tubing yog tsawg dua 0.01 hli / xyoo, tsuas yog 1/5 ntawm cov nickel{12}}raws li alloys. Qhov tseem ceeb tshaj, titanium rods pom zoo heev tiv thaiv kev ntxhov siab corrosion cracking. Raws li kev sib koom ua ke ntawm cov khoom sib hloov thiab cov xov xwm corrosive, lawv lub neej qaug zog yog ntau dua 10 npaug ntawm cov hlau zoo tib yam, ua tiav cov teeb meem ntawm luv luv - nyob siab - cov kav dej sulfur.
Tsis yog-magnetic: Kev tswj zoo li qub rau kev siv lub cev muaj zog, sib sib zog nqus sib sib zog nqus- Kev Tshawb Fawb Hiav Txwv
Hauv kev sib sib zog nqus- hiav txwv drilling, geomagnetic teb cuam tshuam yog "pib tua neeg" cuam tshuam qhov tseeb ntawm kev ntsuas thaum drilling. Ib txwm siv cov yeeb nkab steel laum, vim lawv qhov siab sib nqus permeability, distort geomagnetic signals, ua rau inclination ntsuas yuam kev ntau tshaj 5 degree. Titanium rods, nrog ze - nqus hlau nplaum permeability, tuav lub xeev "zero-magneticization" txawm nyob rau hauv lub zog magnetic teb. Tom qab siv titanium alloy laum cov kav dej rau qhov sib sib zog nqus- hiav txwv drilling platform, qhov tseeb ntawm inclination ntsuas cov ntaub ntawv tau txhim kho mus rau ± 0.1 degree, thiab cov laum me ntsis qhov chaw yuam kev raug txo los ntawm 80%, ua tau zoo kom tsis txhob muaj kev sib tsoo zoo los ntawm kev sib txawv ntawm kev taw qhia. Tsis tas li ntawd, qhov tsis yog -magnetic xwm tshem tawm kev cia siab rau ntawm qhov drilling rigs, ua kom yooj yim xyaum txoj hlua, thiab txo qhov sib sib zog nqus- cov nqi khiav dej hiav txwv.
Lub neej yav tom ntej nyob ntawm no: Titanium Rods Lead Drilling Technology Revolution
Los ntawm "Hiav Txwv Tuag" nyob rau hauv Taklamakan suab puam mus rau "10,000-}meter Abyss" ntawm South Tuam Tshoj Hiav Txwv, titanium rods yog reshaping cov cuab yeej drilling toj roob hauv pes nrog lawv peb yam tseem ceeb: lightness, toughness, thiab ntsiag to. Nrog kev ua tiav hauv cov khoom siv thev naus laus zis, tus nqi ntawm titanium rods tau txo qis los ntawm 60% piv rau kaum xyoo dhau los, ua rau lawv muaj txiaj ntsig zoo rau kev hloov pauv loj ntawm cov khoom siv ib txwm muaj. Nyob rau hauv lub neej yav tom ntej, nrog kev koom ua ke ntawm cov cuab yeej ntse drilling thiab titanium-raws li cov ntaub ntawv sib xyaw, titanium rods yuav hloov zuj zus ntxiv mus rau qhov kub thiab txias tsis kam thiab cuam tshuam, muab kev txhawb zog rau kev drilling hauv qhov chaw huab cua.
Thaum lub laum me ntsis nkag mus rau txheej txheej kawg ntawm pob zeb, thaum cov roj thiab cov pa tawm mus, lub suab ntsiag to ntawm titanium pas nrig yuav tsis pom tseeb, tab sis nws txoj kev txawj ntse ntawm "kev kov yeej lub zog nrog softness" tso cai rau tib neeg mus ntxiv thiab xyaum tob hauv qhov chaw huab cua. Qhov no zoo li tus pas hlau zoo li no muaj qhov ua tau zoo kawg nkaus ntawm kev tshawb nrhiav lub zog, sau ib tshooj lus dab neeg hauv cov ntaub ntawv tshawb fawb.
