Tubing taub hau hauv kev ua haujlwm roj & roj

Covcev headyog ib qho tseem ceeb ntawm cov rooj sib txoos hauv lub cev. Nws yog ib tug tshwj xeeb flanged ntaus ntawv los yog spool ntsia rau saum toj ntawm lub Uppermost casing taub hau ua ntej perforation ua hauj lwm. Cov khoom tseem ceeb no ua haujlwm ua ob lub luag haujlwm tseem ceeb: nws txhawb txoj hlua tubing thaum tsim kom muaj kev ruaj ntseg foob nyob rau hauv qhov chaw nruab nrab ntawm cov tubing thiab cov casing. Tsis tas li ntawd, nws muab kev nkag tau yooj yim rau lub casing-tubing annulus los ntawm cov tswv yim tso tawm sab nraud.
Hauv kev ua haujlwm txhua hnub, lub taub hau tubing ua haujlwm rau ntau yam haujlwm tseem ceeb uas ua kom muaj kev ua haujlwm zoo. Tshaj li tshem tawm txoj hlua downhole tubing, nws zoo seals qhov chaw annular ntawm cov tubing thiab casing. Cov qauv tsim suav nrog qhov tseem ceeb ntawm kev hloov pauv hloov pauv txuas lub taub hau lub taub hau mus rau tsob ntoo Christmas. Tsis tas li ntawd, lub taub hau tubing hla muaj ob sab qhov hluav taws xob uas pab txhawb kev ua haujlwm tseem ceeb xws li kev txhaj tshuaj dej thiab cov txheej txheem ntxuav kom zoo.
Los ntawm cov qauv kev xav, nws muaj ntau yam kev sib koom ua ke ua haujlwm sib haum xeeb. Cov no suav nrog lub taub hau taub hau, tubing hanger, sealing los ua ke, xauv lub qhov rooj, lub qhov rooj valve, lub ntsuas siab, thiab ntau yam flanges. Lub rooj sib txoos sab saum toj txuas mus rau tsob ntoo Christmas los ntawm kev sib txuas flanged lossis clamp-hom kev sib txuas, siv qhov tshwj xeeb flange tsim.
Lub tubing hanger, yog ib qho tseem ceeb ntawm lub rooj sib txoos, zaum ruaj ntseg hauv nws cov kab tapered. Qhov no precision-engineered tivthaiv tsis tau tsuas yog tshem tawm cov tubing hlua tab sis kuj xyuas kom meej sealing zoo ntawm cov raug tshem tawm tubing thiab lub taub hau lub rooj. Rau kev ua tiav cov roj thiab cov roj av, uas feem ntau suav nrog cov kev nyab xeeb ntawm lub qhov rooj, cov tubing hanger tsim yuav tsum muaj cov kab lus tshwj xeeb rau cov kab tswj hydraulic. Nyob rau hauv lub qhov dej nruab nrog hluav taws xob submersible twj tso kua mis, tus tsim yuav txawm ntau sophisticated, yuav tsum tau ntxiv passages rau downhole gas vent li qub thiab kaw hluav taws xob cable nkag.
Lub hauv paus structural lub cev ntawm lub rooj sib txoos yog suav nrogcev headntoo khaub lig, nyob rau hauv lub plawv ntawm lub rooj sib txoos. Cov khoom siv no tsim kev sib txuas tseem ceeb ntawm lub taub hau lub taub hau ntawm nws qhov qis kawg thiab tsob ntoo Christmas ntawm nws sab sauv, nrog lub nplhaib hlau ruaj ruaj ruaj ruaj kom muaj kev ncaj ncees ntawm ob qho kev sib txuas. Tus ntoo khaub lig ua haujlwm raws li ob qho tib si cov cab kuj thiab vaj tse rau lub tubing hanger thaum ua kom muaj ntau yam haujlwm tseem ceeb, suav nrog rau pem hauv ntej thiab rov qab rov qab ncig zoo ntxuav, casing siab xyuas, thiab ntau yam kev khiav hauj lwm los ntawm tubing-casing annulus.
Kev ruaj ntseg ntawm tubing lub taub hau sib dhos cia siab ntau rau ntawm tubing hanger lock screws, uas yuav tsum tau muab tso rau thaum lub tubing hanger yog qhov zoo. Cov ntsia hlau xauv no ua lub luag haujlwm tseem ceeb hauv kev ruaj ntseg tubing hanger, tiv thaiv kev tsis xav tau ntsug lossis kev sib hloov uas tuaj yeem cuam tshuam kev ncaj ncees.
Ua kom tiav lub rooj sib txoos yog lub xauv ntsia hlau flange phaj, mounted ruaj ntseg ntawm tus ntoo khaub lig casing. Cov khoom siv no muab lub rooj zaum ruaj khov rau lub tubing hanger thaum ua ob txoj haujlwm tseem ceeb: nws compresses lub ntim los tsim kom muaj kev sib khi zoo hauv cov tubing-casing annulus thaum tib lub sij hawm tuav lub tubing tiv thaiv lub zog loj uas tuaj yeem tsim los ntawm kev poob qis heev.
