Casing hangersNws yog ib qho tseem ceeb rau kev ruaj ntseg, kev nyab xeeb, thiab kev ua haujlwm ntawm cov roj thiab roj zoo drilling kev ua haujlwm. Cov cuab yeej tshwj xeeb no yog tsim los txhawb thiab ruaj ntseg cov hlua khi hauv qhov dej, muab ntau yam haujlwm tseem ceeb uas ua rau lub qhov dej ruaj khov.
Suspension ntawm Casing
Txhawb nqa qhov hnyav ntawm cov hlua casing yog ib qho ntawm cov haujlwm tseem ceeb ntawm aCasing hanger. Cov kav dej loj loj hu ua cov hlua khi nyob ib puag ncig lub qhov dej thiab muab kev txhawb nqa thiab kev sib cais rau thaj chaw sib txawv. Cov hlua khi no tuaj yeem hnyav ntau, tshwj xeeb tshaj yog nyob rau hauv qhov dej tob, yog li nws yog ib qho tseem ceeb uas yuav tsum muaj cov txheej txheem ruaj khov los txhawb lawv qhov hnyav thiab ua kom lawv tsis txhob tawg lossis txav mus rau hauv qhov dej.
Casing hangersyog npaj los txhawb nqa qhov hnyav ntawm cov hlua casing, uas tuaj yeem nyob ntawm ntau txhiab mus rau lab phaus nyob ntawm qhov tob thiab qhov tsis zoo ntawm lub qhov dej. Ncua lub casing ntawm lub qhov dej zoo pab faib cov khoom sib npaug thiab tiv thaiv kev ntxhov siab ntau dhau ntawm ib qho chaw ntawm lub qhov dej. Qhov kev ncua kev ua haujlwm no yog qhov tseem ceeb rau kev ua kom lub qhov dej muaj kev ncaj ncees thaum lub sijhawm ua haujlwm.
Nws tsim tso cai rau lawv tuav lub casing kom ruaj khov thaum tseem muab lub hauv paus muaj zog rau nws so. Qhov no tau lees paub tias lub casing tseem nyob hauv qhov chaw txawm tias nyob rau hauv qhov xwm txheej hnyav, xws li kev kub ntxhov lossis kub hloov pauv pom nyob rau hauv qhov chaw tob tob. Los ntawm kev tshem tawm cov casing zoo, cov hangers no ua rau muaj txiaj ntsig zoo rau lub qhov dej tag nrho kev ruaj ntseg thiab kav ntev.
Hloov ntawm Casing Nyhav
Lwm qhov tseem ceeb ua haujlwm ntawmCasing hangersyog kev hloov pauv ntawm qhov hnyav ntawm qhov hnyav los ntawm qhov drilling rig's derrick mus rau lub xub pwg nyom hauv lub taub hau los yog spool. Qhov kev hloov pauv qhov hnyav no yog ib kauj ruam tseem ceeb hauv cov txheej txheem tsim kho qhov dej, vim nws ua kom cov casing tau zaum zoo thiab txhawb nqa hauv lub qhov dej zoo.
Thaum lub sij hawm lub installation txheej txheem, cov hlua casing yog thawj zaug txhawb nqa los ntawm qhov drilling rig's derrick. Raws li lub casing yog qis rau hauv lub qhov dej, nws qhov hnyav nce zuj zus. Thaum lub casing ncav cuag nws qhov tob, nws yog siv los hloov qhov hnyav no los ntawm kev txhawb nqa ib ntus ntawm derrick mus rau cov qauv kev txhawb nqa mus tas li hauv lub qhov dej.
Centering ntawm Casing
Casing hangerskuj tseem ua haujlwm tseem ceeb ntawm qhov nruab nrab ntawm lub casing hauv lub qhov dej. Qhov kev ua haujlwm hauv nruab nrab no yog qhov tseem ceeb rau kev ua kom muaj kev faib tawm ntawm lub zog thiab tswj qhov tseeb ntawm lub casing thaum lub sijhawm ua haujlwm drilling thiab tsim khoom.
Nws tsim muaj cov yam ntxwv uas pab kom ua tiav qhov chaw nruab nrab no. Piv txwv li, ntau lub hangers suav nrog cov ntsiab lus hauv nruab nrab lossis cov ntawv nplaum uas tuav lub casing thiab muab nws tso rau hauv lub qhov dej zoo. Qee qhov kev tsim kho siab heev txawm tso cai rau kev hloov kho kom ntseeg tau tias qhov chaw zoo, txawm tias nyob rau hauv cov xwm txheej nyuaj.
Kev Muab Ib Lub Tuam Txhab Tseem Ceeb
Tej zaum yog ib txoj hauj lwm tseem ceeb tshaj plaws ntawm aCasing hangeryog muab lub ntsiab foob nyob rau hauv lub casing annulus. Lub casing annulus yog qhov sib txawv ntawm lub casing lub sab nrauv phab ntsa thiab lub wellbore los yog ua ntej casing hlua. Sealing no annulus yog ib qho tseem ceeb rau kev khaws cov hydrocarbons thiab lwm yam kua los ntawm kev khiav tawm ntawm lub qhov dej, ua kom muaj kev nyab xeeb thiab kev tiv thaiv ib puag ncig.
Casing hangers' sealing lub luag hauj lwm yog nquag ntxiv los ntawm cov txheej txheem kev sib khi thib ob xws li cov khoom ntim khoom lossis cov khoom sib khi, uas muab kev rov ua dua thiab txhim kho tag nrho cov kev ua haujlwm zoo.
