Tubing Hanger
Aug 31, 2023
Lub tubing hanger yog ib qho tseem ceeb ntawm cov kav dej zoo hauv kev lag luam roj thiab roj. Nws yog ib feem tseem ceeb ntawm cov txheej txheem ua tiav zoo thiab siv los txhawb thiab kaw cov tubing ntau lawm hauv qhov dej. Tubing hanger feem ntau yog nyob rau hauv lub tubing taub hau spool los ua ke, uas yog ntsia rau saum lub qhov dej casing.
Ntawm no yog cov yam ntxwv tseem ceeb thiab kev ua haujlwm ntawm tubing hanger:
Kev them nyiaj yug rau Tubing Ntau Lawm: Lub hom phiaj tseem ceeb ntawm lub tubing hanger yog los txhawb txoj hlua ntau lawm, uas nqa cov hydrocarbons (roj thiab roj) los ntawm lub reservoir mus rau saum npoo. Tubing hanger feem ntau yog tsim los tuav qhov hnyav ntawm txoj hlua tubing thiab txhua yam khoom siv txuas nrog nws.
Sealing Mechanism: Lub raj hanger suav nrog cov txheej txheem sib khi los tiv thaiv kev xau ntawm lub annulus (qhov chaw nruab nrab ntawm cov tubing thiab cov kav dej zoo) thiab lub raj sab hauv. Qhov no yuav pab kom ntseeg tau tias cov kua dej uas tsim tau raug muaj thiab raug coj mus rau saum npoo.
Cov Ntsiab Lus Txuas rau Cov Cuab Yeej Downhole: Ntau yam cuab yeej downhole thiab cov khoom siv, xws li kev nyab xeeb li qub, cov tshuaj txhaj tshuaj, thiab cov cuab yeej saib xyuas, tuaj yeem txuas rau lub raj hanger. Qhov no tso cai rau kev tswj xyuas, saib xyuas, thiab kev saib xyuas kev ua haujlwm zoo.
Compatibility thiab Design Variations: Tubing hangers tuaj nyob rau hauv txawv designs kom haum raws li ntau yam zoo tej yam kev mob, pressures, thiab ua hauj lwm yuav tsum tau. Qee cov qauv tsim muaj cov tshuab hydraulic rau kev teeb tsa los yog rov qab cov tubing hanger, uas tuaj yeem ua tau zoo nyob rau hauv cov dej tob lossis hauv qab dej.
Locking Mechanisms: Tubing hangers feem ntau suav nrog cov txheej txheem kaw kom ruaj ntseg rau hauv qhov chaw thaum nws nyob hauv qhov chaw zoo. Qhov no tiv thaiv kev txav tsis tau ntawm lub hanger thaum tsim khoom.
Khoom siv thiab txheej: Tubing hangers feem ntau yog tsim los ntawm cov khoom siv ruaj khov uas tuaj yeem tiv taus qhov hnyav hauv qhov chaw ib puag ncig, suav nrog kev raug kub siab, kub, thiab cov kua dej corrosive. Lawv kuj yuav raug coated los yog kho kom lawv tsis kam mus corrosion.
Kev tshem tawm thiab hloov pauv: Nyob rau lub neej ntawm lub qhov dej, tej zaum yuav muaj qhov xwm txheej uas yuav tsum tau muab tshem tawm lossis hloov kho, kho, lossis kev pabcuam zoo.
