Packers Retrieving Kev txiav txim siab

1. Tso packer nrog yam tsawg kawg nkaus tubing manipulation, ncaj rub, los yog 1/3 tig tawm.

Ntau zaus cov xwm txheej zoo lossis lwm yam khoom siv downhole hauv txoj hlua ua rau nws tsim nyog kom muaj cov packer tso nrog me me los yog tsis muaj tubing manipulation. Deviated qhov yog cov piv txwv ntawm yav dhau los, thaum lub xub ntiag ntawm eccentric gas nqa sab hnab tshos mandrels los yog ntev ntawm 1/4 "tswj kab hauv lub qhov yuav yog cov piv txwv ntawm tom kawg. Ib qho ncaj rub tawm mechanism yog qhov kev xaiv zoo tshaj plaws hauv feem ntau. Cov packers no feem ntau yog shear pinned nyob rau hauv txoj hauj lwm teeb tsa (tshwj tsis yog - qee qhov nro teeb hom). Lwm qhov kev xaiv yog hom kev sib hloov yam tsawg kawg nkaus (1/3 tig ntawm lub pob) uas qee qhov rov qab tau muaj. Muaj ntau lub foob bore hom retrievable raug tso tawm los ntawm ncaj nro tab sis tsuas yog tom qab lub tshuab foob tau raug rub. Cov packers no xav tau ib qho kev mus txawv tebchaws ntxiv nrog cov cuab yeej tso tawm kom thiaj li rub lub pob. Txawm li cas los xij, tsis xav tau kev sib hloov tubing. Ob peb cov packers tshwj xeeb kuj tau tsim thiab khiav uas ncaj nraim rub tawm tom qab lub tes tsho wireline tau hloov lawm. Qhov kev xaiv no yog me ntsis tsis nyiam vim hais tias lub peev xwm los rub lub packer yog nyob ntawm wireline nkag mus rau lub packer. Tsis muaj kev nkag mus rau tubing tej zaum yuav zoo heev yog vim li cas rau qhov yuav tsum tau rub cov khoom ntim hauv thawj qhov chaw.

2. Thaub qab tso tawm muaj peev xwm, kev ruaj ntseg shear tso tawm, los yog rotating tso tawm.

Cov xwm txheej tsis zoo, teeb meem kev tsim khoom tsis tau npaj tseg, thiab kev tsis sib haum nrog lwm cov cuab yeej downhole yog txhua qhov laj thawj uas yuav ua rau muaj peev xwm rov qab tso tawm qhov xav tau. Yog tias thawj qhov kev tso tawm mechanism tsis tuaj yeem lossis tsis ua haujlwm rau qee qhov laj thawj, qhov zoo li no tseem ceeb heev. Qee lub sij hawm, cov kev muaj peev xwm no tuaj yeem xav tau thiab qhov zoo li no yuav tsum muaj qhov tseem ceeb hauv kev xaiv ntim khoom. Hom kev tso tawm thib ob feem ntau yog los ntawm shearing shear pins lossis screws nrog lub rub ncaj. Txawm li cas los xij, kev sib hloov-hom kev tshaj tawm theem nrab kuj tau muab tso rau hauv qee cov packers.

3. Tubing los yog packer retrievable nrog ib co sau, packer bypass los yog flush seal unit.

Qee qhov kev ua haujlwm ntau lawm yuav ua rau muaj qhov nruab nrab sau rau hauv lub casing saum lub packer. Ib qho piv txwv yuav yog qhov tsim ntawm thaj tsam thib ob saum toj ib lub packer hauv tubing / casing annulus. Cov khoom raug nplua los ntawm cheeb tsam sab saud tuaj yeem khom tawm ntawm lub hnab ntim khoom sab saum toj. Nyob rau hauv tas li ntawd, lub packer yuav tsum tau muab tso rau kom ze li sai tau mus rau hauv qab ntawm lub sab sauv cheeb tsam los yog ib tug zawv zawg lub tes tsho yuav tsum tau muab tso rau ze li sai tau mus rau lub packer sab saum toj. Txawm li cas los xij, txawm tias qee qhov kev nplua yuav nyob twj ywm thiab lub bypass los yog lub siab unloader yog qhov tseem ceeb heev kom tso cai rau cov tubing rau casing ncig saum cov ntsiab lus kom tshem tawm cov nplua lossis cov khib nyiab. Nyob rau hauv tas mus li los yog foob bore hom retrievable, lub foob sib dhos tuaj yeem muab tib lub peev xwm. Qhov no ua haujlwm zoo tshaj plaws thaum lub foob sib dhos sib npaug los yog me me hauv OD dua li cov raj.

4. Sib npaug lub siab ntawm cov ntim tso tawm, lub siab unloader lossis cais lub foob.

Thaum cov packers khiav dhau los ntawm qhov nruab nrab qhov tob, nws tuaj yeem ua tau lossis qhov tshwm sim uas qhov sib txawv ntawm qhov sib txawv yuav muaj nyob thoob plaws lub pob thaum tso tawm. Yog hais tias tus neeg teb xov tooj tsis thauj cov tubing ua ntej tso tawm, lub casing kua siab tej zaum yuav muaj ntau tshaj li qhov siab ntawm ib feem ntawm lub reservoir raug cais tawm. Ib qho kev sib txawv ntawm cov hauv qab no tuaj yeem muaj nyob rau hauv lwm yam mob yog tias lub pas dej sib cais raug them los ntawm kev txhaj tshuaj lossis yog muaj zog ntau dhau.

Nyob rau hauv ob qho tib si, yog tias lub siab sib npaug ntawm qee yam khoom siv tsis muaj, ces muaj qhov ua tau zoo tias cov ntim khoom tso tawm yuav nyuaj, thiab / lossis cov pob khoom yuav raug puas tsuaj hauv cov txheej txheem tso tawm. Qhov no yog ib qho tseem ceeb tshwj xeeb tshaj yog tias tus neeg ntim khoom yuav tsum tau rov pib dua ntawm tib qho kev mus ncig. Ib qho kev xaiv rau lub hauv-siab-unloader tsim feature yog tias tib qhov sib npaug yuav ua tau los ntawm kev rub lub foob los ntawm lub foob bore hom retrievable packer.

5. Tso lub packer uas tsis muaj tubing mus txawv tebchaws, tubing txuas ncaj qha mus rau lub packer.

Raws li tau hais dhau los, qee cov neeg ntim khoom xav tau ib puag ncig ntawm lub raj xa mus kom rov qab tau lub foob sib dhos thiab rov ua haujlwm rub lub cuab yeej. Qhov no tsis tsim nyog hauv qee qhov xwm txheej. Hauv qee cov ntaub ntawv ua haujlwm uas muaj kev ua haujlwm tsis tu ncua, kev lag luam ntawm cov txheej txheem rub tsis tuaj yeem tsim nyog. Yuav kom rub tau lub packer yam tsis tau ua tubing mus txawv tebchaws, nws yuav tsum yog hom uas yog tsim los rau threaded ncaj qha mus rau lub raj thiab tsis yog lub foob bore hom retrievable uas yog txuas mus rau lub tubing ntawm ib tug latch ntawm lub foob. . Qhov kev zam yog lub wireline tso tawm version yav dhau los tham. Ntau yam ntawm cov xov-rau-packer no tuaj yeem hloov kho nrog cov khoom siv yog li cov tubing tuaj yeem raug rho tawm los ntawm lub hnab ntim khoom thiab tseem khaws cov khoom rov qab tau yam tsis muaj tubing ncig mus ncig.

6. Yooj yim milled packer, qhov tsawg kawg nkaus zeb nrug, thiab tsis tig.

Cov kev xav tau rau ib qho yooj yim thiab sai millable mus tas li packer yog pom tseeb. Packer designs uas ua rau qhov no muaj xws li millable hlau Cheebtsam, tsim rau yam tsawg kawg nkaus zeb nrug, tsim rau yam tsawg kawg nkaus milled OD's, thiab anti-rotation locking nta.

Vigor's packer series khoom yog tsim raws li cov qauv siab ntawm API 11D1, thiab tag nrho cov packers los ntawm R & D mus rau ntau lawm mus rau qhov kawg xa mus rau cov neeg muas zaub yog nruj me ntsis tswj thiab sau tseg kom paub meej tias cov khoom zoo tuaj yeem ua tau raws li cov neeg siv khoom xav tau. Yog tias koj txaus siab rau Vigor ntau yam ntawm cov phom perforating, thov tsis txhob yig tiv tauj nrog Vigor pawg kws tshaj lij rau cov khoom lag luam zoo tshaj plaws thiab kev txhawb nqa.
