Muaj nuj nqi thiab cov ntsiab lus tseem ceeb ntawm Packer

Packer yog cov cuab yeej siv tshuab nrog cov khoom ntim tau nruab rau hauv lub thawv tsim, siv los thaiv cov kua (kua lossis roj) kev sib txuas lus los ntawm qhov chaw nruab nrab ntawm cov kav dej los ntawm kev sib khi ntawm qhov chaw nruab nrab ntawm lawv ".

Lub Packer feem ntau yog teem rau saum toj ntawm thaj chaw tsim khoom kom cais cov khoom tsim tawm los ntawm cov khoom lag luam los yog los ntawm cov chaw tsim khoom nyob rau lwm qhov hauv lub qhov dej.

Nyob rau hauv cased qhov ua tiav, cov casing yog khiav raws tag nrho ntev ntawm lub qhov dej thiab los ntawm lub reservoir. Lub cased qhov ua tau zoo ua raws li kev tswj hwm kev nyab xeeb ntawm cov khoom siv hydrocarbons uas xav tau thiab ua ib qho kev tiv thaiv kev tiv thaiv kev rov qab los ntawm cov dej tsis xav tau, gases, thiab cov khib nyiab rau hauv qhov dej.

Tom qab cov hlua tho raug tshem tawm, qhov txuas txuas txuas ntxiv ntawm cov kab sib txawv ntawm qhov sib txawv yog khiav mus rau hauv qhov dej ntawm qhov sib txawv ntawm qhov tob thiab ruaj ntseg rau kev tsim hauv cov txheej txheem hu ua Cementing. 'Cement' ntawm no yog hais txog kev sib xyaw ntawm cov cement thiab qee cov khoom ntxiv uas tau muab tso rau hauv qhov dej thiab ua rau lub tshuab nqus tsev ntawm lub casing thiab ib puag ncig tsim.

Tom qab lub qhov dej tau raug rwb thaiv tsev tag nrho los ntawm qhov tsim ib puag ncig, lub casing yuav tsum tau perforated los txhawb kev tsim khoom los ntawm cov khoom siv tau zoo ntawm lub pas dej hu ua 'thaj chaw them nyiaj'. Perforation yog ua los ntawm kev siv 'Perforating phom' uas tau teeb tsa cov kev txwv kev tawg uas tawg qhov los ntawm cov ntu tshwj xeeb ntawm lub casing (thiab rau hauv lub reservoir) rau kev tswj cov hydrocarbons.

Parveen muaj cov kab tiav ntawm cov khoom ntim khoom thiab cov khoom siv - los ntawm cov qauv ntim khoom mus rau cov qauv tsim tshwj xeeb rau qhov chaw muaj kev phem tshaj plaws. Peb cov packers yog tsim raws li API 11 D1 Validation Qib V6-V0 thiab Kev Tswj Xyuas Qib Q3-Q1.

Lub luag haujlwm ntawm Packer: 

• Ntxiv nrog rau kev muab lub foob ntawm lub raj thiab lub casing, lwm txoj haujlwm ntawm lub hnab ntim khoom yog raws li hauv qab no:
• Tiv thaiv downhole txav ntawm txoj hlua tubing, tsim cov axial nro los yog compression loads ntawm txoj hlua tubing.
• Txhawb qee qhov hnyav ntawm tubing qhov twg muaj qhov tseem ceeb compressive load ntawm txoj hlua tubing.
• Tso cai rau qhov zoo tshaj plaws ntawm qhov dej ntws zoo (cov hlua tubing) kom ua tau raws li cov qauv tsim los yog kev txhaj tshuaj txaus.
• Tiv thaiv cov casing ntau lawm (puab casing hlua) los ntawm corrosion los ntawm cov kua ua kua thiab kev kub siab.
• Muaj peev xwm muab tau ib txoj kev sib cais ntau qhov chaw tsim khoom.
• Tuav cov kua dej uas muaj kev pabcuam zoo (tua kua dej, ntim cov kua dej) hauv lub hnab ntim khoom.
• Yooj yim nqa khoom siv, xws li kev nqa roj txuas ntxiv los ntawm A-annulus.

Packer Cov Khoom Tseem Ceeb:

• Lub cev los yog mandrel:

Mandrel yog ib qho tseem ceeb ntawm lub packer uas muaj qhov kawg kev sib txuas thiab muab ib tug conduit los ntawm lub packer. Nws raug cuam tshuam ncaj qha rau cov dej ntws, yog li nws cov khoom siv yog qhov kev txiav txim siab tseem ceeb heev. Cov khoom siv feem ntau yog L80 Hom 1, 9CR, 13CR, 9CR1Mo. Rau ntau corrosive thiab qaub cov kev pab cuam Duplex, Super Duplex, Inconel kuj siv raws li qhov yuav tsum tau muaj.

• Daim ntawv:

Cov nplaum nplaum yog cov cuab yeej zoo li lub ntsej muag nrog wickers (lossis cov hniav) ntawm nws lub ntsej muag, uas nkag mus thiab tuav cov phab ntsa casing thaum lub ntim ntim. Muaj ntau hom slip designs muaj nyob rau hauv packers xws li dovetail slips, rocker type slips bidirectional slips nyob ntawm seb packer los ua ke yuav tsum tau.

• Cone:

Lub khob hliav qab yog beveled kom phim rau sab nraub qaum ntawm daim tiab thiab ua ib qho kev sib tw uas tsav lub plam tawm sab nraud thiab mus rau hauv cov phab ntsa casing thaum teeb tsa lub zog siv rau lub pob.

• Packing-element system

Cov khoom ntim yog qhov tseem ceeb tshaj plaws ntawm txhua lub ntim khoom thiab nws muab lub hom phiaj tseem ceeb ntawm kev sib khi. Thaum cov ntawv hlais tau txav mus rau hauv cov phab ntsa casing, ntxiv kev siv qhov chaw quab yuam energizes lub packing-element system thiab tsim ib lub foob ntawm lub packer lub cev thiab sab hauv txoj kab uas hla ntawm lub casing. Cov khoom siv feem ntau yog NBR, HNBR lossis HSN, Viton, AFLAS, EPDM thiab lwm yam. Cov khoom siv nrov tshaj plaws yog ib qho khoom siv ruaj khov nrog lub nplhaib nthuav dav, peb daim kab ke nrog lub nplhaib spacer, ECNER lub cev, lub caij nplooj ntoos hlav loaded element system, Fold rov qab nplhaib element system.

• Lub nplhaib xauv:

Lub nplhaib xauv ua lub luag haujlwm tseem ceeb hauv kev ntim khoom. Lub hom phiaj ntawm lub nplhaib xauv yog xa cov axial loads thiab tso cai rau unidirectional txav ntawm cov khoom ntim khoom. Lub nplhaib xauv yog ntsia rau hauv lub xauv lub nplhaib vaj tse thiab ob qho tib si txav ua ke hla lub nplhaib xauv mandrel. Tag nrho cov teeb tsa quab yuam tsim tawm vim lub siab tubing raug kaw rau hauv pob khoom los ntawm lub nplhaib xauv.

Raws li ib qho ntawm cov ua lag luam ntawm packers, Vigor muaj nplooj siab los teeb tsa cov qauv kev lag luam rau kev ua tau zoo thiab kev ntseeg siab. Peb cov engineers coj ntau xyoo ntawm kev paub dhau los hauv ob qho tib si hauv daim ntawv thov thiab kev siv cov packers, muab peb cov kev nkag siab zoo rau lawv lub luag haujlwm tseem ceeb hauv kev ua tiav drilling. Peb nkag siab tias cov khoom ntim khoom zoo tuaj yeem cuam tshuam kev ua haujlwm thiab kev nyab xeeb, yog li peb pheej nqis peev hauv kev tshawb fawb thiab kev tsim kho. Peb lub hom phiaj yog txhawm rau tsim kho tshiab thiab tsim cov kev daws teeb meem packer uas zoo kawg nkaus rau kev siv hauv ntiaj teb tiag.

Ntawm Vigor, peb muab qhov tseem ceeb rau peb cov neeg siv khoom xav tau, kom ntseeg tau tias peb cov khoom tsis yog tsuas yog ua tau raws li tab sis tshaj qhov kev cia siab. Yog tias koj txaus siab tshawb nrhiav peb cov kev tsim kho tshiab tshiab los yog lwm cov cuab yeej hauv qab qhov drilling, peb xav kom koj ncav cuag. Peb pab pawg kws tshaj lij tau npaj los muab kev txhawb nqa kev tshaj lij rau koj thiab cov khoom lag luam zoo tsim tshwj xeeb rau koj cov kev xav tau. Koj txoj kev vam meej yog peb lub luag haujlwm, thiab peb nyob ntawm no los pab koj ua tiav.
