✧ Kev piav qhia
Lub Taub Hau Casing yog cov khoom siv tseem ceeb heev uas siv rau hauv cov txheej txheem drilling, lub taub hau casing tuaj yeem tswj tau qhov siab ntawm lub qhov dej, lub taub hau casing feem ntau yog welded lossis screwed rau saum cov yeeb nkab conductor lossis lub casing ces dhau los ua ib feem ntawm lub qhov dej ntawm lub qhov roj.
Lub Taub Hau Casing muaj lub tais ncaj nraim nrog 45 ° tsaws lub xub pwg tsim uas zam kev puas tsuaj rau thaj chaw sib khi los ntawm cov cuab yeej drilling thiab tiv thaiv kev sim ntsaws thiab lub tais tiv thaiv teeb meem wedging thaum muaj kev siab.
Lub Taub Hau Casing feem ntau yog muab nrog cov qhov hluav taws xob threaded thiab cov qhov hluav taws xob studded thiab kuj tuaj yeem tsim los ntawm kev thov. Cov kev sib txuas hauv qab tuaj yeem muab threaded lossis slip-on rau kev vuam.
Lub Taub Hau Casing siv tau rau kev ua tiav ib zaug thiab qauv ntawm kev ua tiav ob zaug.
Lub taub hau casing muaj qhov txuas flange sab saum toj rau kev teeb tsa thiab tshem tawm yooj yim, nrog rau kev tsim qauv ncaj nraim kom yooj yim rau kev khiav thiab rov qab tau cov hlua casing. Tsis tas li ntawd, nws muaj cov foob zoo tshaj plaws thiab cov txheej txheem ntim khoom kom ntseeg tau tias muaj kev sib txuas ruaj ntseg thiab tsis muaj qhov xau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm API6A Casing Head yog nws qhov kev ua tau zoo thiab kev sib raug zoo nrog ntau yam khoom siv wellhead thiab cov khoom siv. Nws tuaj yeem siv ua ke nrog cov casing hangers, tubing heads, thiab lwm yam khoom los tsim kom muaj lub rooj sib dhos wellhead tiav uas ua tau raws li qhov xav tau tshwj xeeb ntawm txhua qhov project drilling lossis ntau lawm.
✧ Qhov tshwj xeeb
1. Tsim qauv ncaj nraim, Siv lub xub pwg nyom 45 °.
2. Txais ntau yam ntawm cov ntaub thaiv thiab cov mandrel casing hangers.
3. Muaj ib qho lockscrews ntxiv rau kev tiv thaiv tais diav.
4. Tso cai rau kev siv cov ntsia hlau xauv kom khaws cov khoom dai.
5. Peb hom qhov hluav taws xob sib txawv: Cov yeeb nkab kab, Flanged (Studded) Cov qhov hluav taws xob txuas ntxiv.
6. Ntau qhov kev sib txuas hauv qab, xws li: Slip-on weld, Slip-on weld nrog O-ring, Threaded thiab Sure Lock.
