Downhole sealing kev daws teeb meem tsim qhov cuam tshuam tseem ceeb ntawm cov dej hauv qhov dej thiab qhov chaw ib puag ncig, ua kom muaj kev ncaj ncees, kev ua haujlwm ruaj ntseg, thiab kev tsim khoom. Hauv kev lag luam roj thiab roj, kev sib khi thev naus laus zis yuav tsum tiv taus cov xwm txheej hnyav nrog rau qhov kub siab tshaj 300 degree, siab tshaj 20,000 psi, thiab corrosive ib puag ncig uas muaj hydrogen sulfide, carbon dioxide, thiab siab - salinity brines. Kev kub siab kub cov ntsaws ruaj ruaj uas tsim los ntawm cov khoom siv elastomeric siab heev tau dhau los ua cov khoom tseem ceeb hauv cov cuab yeej ua tiav, kev nyab xeeb li qub, thiab cov khoom siv hauv lub taub hau.
Kev lag luam ntsiab lus
Lub ntiaj teb roj thiab roj sealing kev lag luam txuas ntxiv hloov zuj zus nyob rau hauv cov lus teb rau kev nyuaj drilling thiab ntau lawm ib puag ncig. Kev tshawb nrhiav dej tob, HPHT reservoirs, thiab cov peev txheej tsim kho tsis zoo xav tau cov ntsaws ruaj ruaj uas tuav lawv txoj kev ncaj ncees nyob rau hauv cov xwm txheej uas sai sai degrade cov pa elastomers. Kev hloov mus rau FFKM cov ntsaws ruaj ruaj thiab HNBR cov ntsaws ruaj ruaj qhia txog kev lag luam kev lees paub tias cov khoom siv sealing zoo tshaj plaws xa rov qab los ntsuas tau los ntawm kev txo qis tsis yog - lub sijhawm tsim khoom thiab txuas ntxiv cov khoom siv lub neej. Kev txheeb xyuas kev lag luam ua haujlwm siab -kev ua tau zoo elastomer sealing ntu kom ncav cuag $ 1.6 nphom los ntawm 2034.
Technical Overview
Tuam Tshoj Vigor cov kev daws teeb meem sealing portfolio hais txog tag nrho spectrum ntawm downhole thiab nto sealing yuav tsum tau los ntawm plaub yam khoom tshwj xeeb. Lub tuam txhab O-ring seals, tsim los ntawm hwm HNBR, FKM, thiab FFKM cov khoom sib txuas, muab kev sib khi tseem ceeb thoob plaws cov cuab yeej ua tiav thiab cov cuab yeej zoo. HNBR cov ntaub ntawv muaj qhov tshwj xeeb tensile lub zog thiab kev puas tsuaj nrog kev ua haujlwm ntev ntev - lub sijhawm khaws cov khoom tom qab txuas ntxiv mus rau tshav kub, roj, thiab tshuaj lom neeg.
Ntawm qib kev ua tau zoo tshaj plaws, FFKM cov ntsaws ruaj ruaj muab qhov ntsuas kub zoo tshaj plaws muaj nyob rau hauv cov ntaub ntawv elastomeric, nrog cov qib tshwj xeeb muaj peev xwm ua tau zoo sealing los ntawm -40℃mus rau ntau dua 316℃thaum tuav cov tshuaj tiv thaiv zoo heev. V- hom kev sib txuas ua ke sawv cev rau txoj hauv kev sib xyaw ua ke tshiab, sib xyaw cov ntaub ntawv hlau nrog siab - kub sealing compounds kom tiv taus thermal expansion cycles ntawm siab txog 10,000 psi. Rau qhov xav tau H2S ib puag ncig, Tuam Tshoj Vigor lub caij nplooj ntoos hlav-energized seals xa cov kev ua tau zoo tshwj xeeb nrog kev sib txhuam coefficients hauv qab 0.1 thiab txhim khu kev sib khi ntawm 25,000 psi.
Daim ntawv thov teb
Hauv kev ua haujlwm hydraulic fracturing, fracturing equipment seals yuav tsum tiv thaiv rov qab raug rau abrasive proppant - cov kua dej thiab lub zog siab heev. Tuam Tshoj Vigor's fracturing khoom foob muab kev ruaj ntseg sealing los ntawm -60℃mus rau 120℃ntawm siab txog li 20,000 psi. Hauv cov ntawv thov ua tiav hauv dej tob, V- hom kev sib txuas cov ntsaws ruaj ruaj tau pom qhov ua tau zoo tshwj xeeb hauv siab -cov roj qhov dej siab, qhov twg lawv cov txheej txheem ntau- txheej txheej muab kev poob siab thiab tawg-pov thawj yam ntxwv.
Rau subsurface kev nyab xeeb li qub thiab qhov chaw siab -siab manifolds, lub caij nplooj ntoos hlav- lub zog ntsaws ruaj ruaj xa cov kev txhim khu kev qha, reciprocating, thiab zoo li qub sealing hla qhov kub ntawm -252℃rau 316 degree, ua rau lawv haum rau ob qho tib si Arctic thiab geothermal daim ntaub ntawv.
Xaus
Qhov kev ncaj ncees ntawm txhua qhov dej hauv qhov kawg yog nyob ntawm qhov zoo ntawm nws cov kev daws teeb meem sealing. Tuam Tshoj Vigor's engineered sealing portfolio, xws li precision O-ring seals mus rau lub caij nplooj ntoos hlav tshwj xeeb-energized seals thiab V-hom sealing seals, muab cov neeg ua haujlwm nrog cov khoom siv txuj ci uas xav tau los daws qhov kev xav tau tshaj plaws ntawm kev sib tw downhole sealing.
