Kev nyab xeeb thiab ua haujlwm tau zoo ntawm kev tshawb nrhiav roj thiab roj thiab kev lag luam tsim khoom yog nyob ntawm cov khoom siv zoo. Ob yam tseem ceeb ntawm cov cuab yeej no yog cov tubing hangers thiab covcasing hangers. Thaum ob qho tib si ua haujlwm tseem ceeb hauv kev tsim kho thiab tsim khoom, lawv muaj cov hom phiaj thiab cov yam ntxwv sib txawv.
Kev txhais thiab kev ua haujlwm
Nyob rau hauv lub qhov dej, cov hlua casing raug tshem tawm thiab kaw siv lub cuab yeej hu ua acasing hanger. Nws yog nyob rau hauv lub qhov dej los yog lub taub hau casing thiab feem ntau yog ntsia rau saum toj ntawm txhua txoj hlua casing. Lub hom phiaj tseem ceeb yog los txhawb qhov hnyav ntawm txoj hlua casing thiab tsim ib lub foob ntawm lub casing thiab lub qhov dej.
Nyob rau hauv sib piv, ntau lawm tubing hlua yog tsim los muab ncua thiab kaw nyob rau hauv lub qhov dej nrog ib tug tubing hanger. Nws ua haujlwm raws li qhov txuas ntawm lub taub dej thiab tsob ntoo Christmas thiab feem ntau yog qhov siab tshaj plaws ntawm kev tsim kho. Lub tubing hanger lub luag haujlwm tseem ceeb yog los txhawb qhov hnyav ntawm cov tubing ntau lawm thiab muab lub foob rau kev khiav ntawm kev tsim khoom.
Installation Timing thiab Well Lifecycle
Casing hangerstau txhim tsa thoob plaws hauv lub sijhawm ua haujlwm zoo, tshwj xeeb tshaj yog thaum lub sijhawm ua haujlwm thiab cementing txheej txheem. Lawv ua lub luag haujlwm tseem ceeb hauv cov theem pib ntawm txoj kev loj hlob zoo, muab kev txhawb nqa kev tsim kho thiab kev sib cais zonal thaum lub qhov dej tau drilled thiab ua tiav.
Tubing hangers feem ntau yog haum tom qab lub qhov dej drilled thiab lub casing yog teem. Lawv raug ntsia thaum lub sijhawm ua tiav cov txheej txheem zoo, tom qab cov tubing ntau lawm tau khiav mus rau hauv qhov dej. Tubing hangers tseem nyob hauv qhov chaw thoob plaws lub neej ntawm lub qhov dej.
Tsim thiab Tsim
Casing hangersfeem ntau loj dua thiab muaj zog dua hauv kev tsim kho piv rau tubing hangers. Lawv tau tsim los txhawb qhov hnyav hnyav, feem ntau ntau pua txhiab phaus, nyob ntawm qhov tob thiab qhov loj ntawm txoj hlua casing. lawv feem ntau muaj cov txheej txheem plam kom tuav thiab txhawb nqa lub casing, nrog rau cov khoom sib khi kom tiv thaiv cov dej tsiv teb tsaws ntawm lub casing thiab lub taub hau.
Tubing hangers feem ntau me me thiab ntau compact duacasing hangers. Lawv tau tsim los pab txhawb qhov hnyav hnyav ntawm cov hlua hlau ntau lawm. Tubing hangers feem ntau suav nrog ntau yam kev sib khi thiab tej zaum yuav suav nrog ntau qhov chaw nres nkoj thiab cov chaw rau kev tsim khoom, tshuaj txhaj tshuaj, thiab hydraulic lossis hluav taws xob tswj kab.
Load-Bearing Peev Xwm
Vim tias qhov hnyav ntawm txoj hlua casing tuaj yeem siab, tshwj xeeb tshaj yog nyob rau hauv qhov dej tob,casing hangersyog tsim los tiv taus qhov hnyav hnyav. Lawv yuav tsum muaj kev txhawb nqa dynamic loads thaum lub sij hawm drilling thiab ntau lawm ua hauj lwm ntxiv rau lub casing qhov kev nyuaj siab zoo li qub.
Thaum tubing hangers kuj txhawb nqa qhov hnyav, cov khoom thauj lawv dais feem ntau tsawg dua li ntawmcasing hangers. Cov tubing ntau lawm feem ntau yog sib dua li cov hlua casing. Txawm li cas los xij, tubing hangers yuav tsum tau tsim los tswj cov kev ntxhov siab ntxiv ntawm kev ua haujlwm ntau lawm, suav nrog kev hloov pauv siab thiab muaj peev xwm thermal expansion.
