Hauv kev tshawb nrhiav thiab tsim cov roj thiab cov nkev, cov khoom tshwj xeeb tubular yog cov khoom tseem ceeb nrog rau cov tshuab drilling thiab cov khoom siv. Cov tubulars no, sib sau ua ke hu ua "roj teb chaws tubular khoom" (OCTG), suav nrog laum yeeb nkab, casing, thiab tubing, thiab lwm yam. Raws li cov khoom siv tseem ceeb thiab cov cuab yeej siv tseem ceeb hauv kev lag luam roj thiab roj, OCTG suav txog 40% ntawm tag nrho cov hlau siv thiab 20-30% ntawm tag nrho cov nqi tsim kho. Kev ua tiav ntawm kev ua tiav ntawm cov haujlwm roj thiab roj yog qhov txuas nrog rau qhov zoo ntawm OCTG siv.
Roj Lub Tebchaws Tubular Khoom
OCTG suav nrog ntau yam ntawm cov khoom siv tubular tsim los tiv thaiv qhov xav tau ib puag ncig ntsib thaum ua haujlwm roj thiab roj. Cov no suav nrog laum yeeb nkab rau kev ua haujlwm drilling, casing rau hauv ob sab phlu thiab txhawb nqa lub qhov dej, tubing rau kev tsim khoom, thiab lwm yam dej num hauv qhov chaw. OCTG cov khoom lag luam yog tsim los rau cov kev qhia tshwj xeeb, kom ntseeg tau tias lawv muaj lub zog tsim nyog, ua haujlwm ntev, thiab cov yam ntxwv ua haujlwm kom muaj kev ntseeg siab rau hauv qhov hnyav downhole.
Evolution ntawm Tuam Tshoj OCTG Manufacturing Capabilities
Nyob rau hauv nruab nrab -1990s, Tuam Tshoj lub teb chaws OCTG kev tsim muaj peev xwm raug txwv tsis pub muaj ntau, ntau yam, thiab zoo, ua tsis tau raws li qhov kev xav tau ntawm lub teb chaws kev lag luam roj thiab roj ntau zuj zus. Los ntawm 1949 txog 1994, Tuam Tshoj tau siv kwv yees li 12.7 lab tons ntawm OCTG, nrog rau 11.5 lab tons raug xa tawm thiab tsuas yog 1.2 lab tons tsim tawm hauv tebchaws.
Txawm li cas los xij, paub txog qhov tseem ceeb ntawm OCTG tus kheej txaus txaus, Tuam Tshoj tau pib ua txoj haujlwm tseem ceeb hauv xyoo 1980 los txhim kho nws cov peev txheej tsim khoom hauv OCTG. Los ntawm ze li ntawm peb lub xyoos ntawm kev mob siab rau, Tuam Tshoj tau ua qhov zoo tshaj plaws strides, vam meej los ntawm tsis muaj OCTG ntau lawm los ua lub ntiaj teb no manufacturing powerhouse.
Niaj hnub no, Tuam Tshoj txoj kev lag luam OCTG tau hloov zuj zus los ntawm kev tsim cov khoom lag luam qis kom muab tag nrho cov API-certified thiab tshwj xeeb tsis-API tubulars. Qhov no suav nrog cov qib high-strength, corrosion-resistant, thiab kab txawv alloy qib raws li qhov xav tau kev ua haujlwm tshaj plaws. Nrog cov thev naus laus zis ntau lawm thiab kev tswj xyuas nruj, Tuam Tshoj cov khoom OCTG tam sim no sib tw thoob ntiaj teb cov qauv.
Yog li ntawd, Tuam Tshoj tau ua tiav kev lag luam hauv tsev tshaj li 80% rau OCTG, nrog tus kheej txaus tus nqi ntawm 99.5%. Lub teb chaws tsis tau tsuas yog ua tau raws li nws cov kev xav tau hauv tsev tab sis kuj tau dhau los ua tus xa tawm ntawm cov khoom lag luam xaiv OCTG hauv xyoo tas los no.
Corrosion-Resistant OCTG rau hnyav ib puag ncig
Kev lag luam roj thiab roj feem ntau ntsib qhov chaw tsim khoom hnyav uas pom los ntawm qhov muaj cov ntsiab lus corrosive xws li hydrogen sulfide (H2S), carbon dioxide (CO2), thiab kub siab thiab siab. Nyob rau hauv cov xwm txheej nyuaj no, tshwj xeeb corrosion-resistant OCTG yog qhov tseem ceeb los xyuas kom meej kev ncaj ncees thiab kev ua haujlwm ntev ntawm cov khoom siv zoo.
Nyob ntawm qhov hnyav ntawm qhov chaw corrosive, ntau yam khoom siv tau siv, xws li martensitic stainless hlau thiab duplex stainless hlau rau hlau-nickel-based alloys thiab txawm tias npib tsib xee-raws li alloys. Piv txwv ntawm corrosion-resistant OCTG muaj xws li H2S-resistant casing, CO2-resistant casing, super 13Cr casing qib, thiab npib tsib xee-raws li alloy casing thiab tubing.
