Qhov txawv ntawm Cast Iron Bridge Plug, Composite Bridge Plug thiab Dissolvable Bridge Plug yog dab tsi?

Cov Lus Piav Qhia Kom Paub Ntxiv
1. Lub Qhov Txuas Choj Hlau Cam Khwb (Tus Neeg Ua Haujlwm Ib Txwm Muaj)

• Nws yog dab tsi: Hom choj txuas thawj thiab ruaj khov tshaj plaws. Nws yog tsim los ntawm hlau cam khwb cia thiab lwm yam khoom siv hlau.
• Nws ua haujlwm li cas: Nws raug teeb tsa rau hauv lub casing siv cov xov hlau, cov raj, lossis cov raj coil. Lub kaw lus slip-wedge rams cov hlau slips rau hauv phab ntsa casing, thiab cov khoom ntim khoom raug nthuav dav kom tsim tau lub foob roj-ntim.
• Qhov Txawv Tseem Ceeb: Ruaj Khoov thiab Muaj Zog Kawg Nkaus. Nws qhov zoo tshaj plaws yog nws lub zog compressive thiab tensile loj heev. Nws yog tsim los ua ib qho thaiv ruaj khov, ib txoj kev.
• Kev Tshem Tawm: Tsuas yog tshem tawm tau los ntawm kev sib tsoo (sib tsoo nws nrog cov cuab yeej tshwj xeeb hauv qhov). Qhov no yog ib qho txheej txheem siv sijhawm ntau thiab kim heev uas xav tau lub tshuab khawb thiab tsim cov hlau khib nyiab ntau uas yuav tsum tau ncig tawm ntawm lub qhov.
• Zoo Tshaj Plaws Rau:

1. Tso tseg qhov dej mus tas li.
2. Cov xwm txheej uas xav tau ib qho kev thaiv tsis muaj qhov tsis ua tiav rau kev nyab xeeb.
3. Cov cheeb tsam cais tawm nrog qhov sib txawv ntawm siab heev.

2. Lub Qhov Txuas Choj Sib Xyaws (Tus Qauv "Drillable" Niaj Hnub)

• Nws yog dab tsi: Ib lub qhov txuas choj ua los ntawm cov khoom siv sib xyaw ua ke - feem ntau yog kev sib xyaw ntawm cov iav fibers, carbon fibers, thiab resins.
• Nws ua haujlwm li cas: Ua haujlwm zoo ib yam li lub ntsaws hlau cam khwb cia hauv cov ntsiab lus ntawm kev teeb tsa (slips, packing elements). Txawm li cas los xij, cov ntaub ntawv sib dua thiab yooj yim dua rau kev tho.
• Qhov Txawv Tseem Ceeb: Yooj Yim Drill. Qhov no yog nws lub hom phiaj tseem ceeb. Cov ntaub ntawv sib xyaw ua ke muaj zog txaus los tuav qhov siab tseem ceeb thaum lub sijhawm ua haujlwm tab sis lawv txhob txwm tawg, txhais tau tias lawv tawg yooj yim hauv qab lub zog ntawm lub ntsis laum.
• Kev Tshem Tawm: Tshem tawm los ntawm kev khawb lossis milling. Cov txheej txheem no sai dua li kev milling hlau cam khwb cia. Cov khib nyiab yog cov hmoov me me, tsis yog hlau, thiab tsis sib txhuam uas yooj yim dua los ntxuav tawm ntawm lub qhov dej, txo qhov kev pheej hmoo ntawm kev ua puas tsuaj rau cov khoom siv hauv qab.
• Zoo Tshaj Plaws Rau:

1. Kev tawg ua ntau theem hydraulic ("Fracking") hauv cov qhov dej kab rov tav. Muaj ntau lub qhov (plugs) no tau teeb tsa los cais cov theem, thiab tom qab ntawd lawv txhua tus tau raug khawb tawm hauv ib qho kev ua haujlwm zoo.
2. Kev cais tawm ib ntus rau kev kuaj lossis kev tsim khoom.
3. Txhua qhov xwm txheej uas koj paub tias koj yuav tsum tshem lub ntsaws thiab rov pib dua kev khawb lossis kev tsim khoom.

3. Choj Plug Yaj Tau(Kev Tsim Kho Tshiab "Teeb thiab Tsis Nco Qab")

• Nws yog dab tsi:Hom tshiab tshaj plaws, ua los ntawm cov hlau (xws li magnesium lossis aluminium alloys) lossis cov polymers uas tau tsim los kom yaj tau raws li qhov kwv yees tau thaum raug rau cov kua dej tshwj xeeb, qhov kub thiab txias, thiab qhov siab.
• Nws ua haujlwm li cas:Nws tau teeb tsa zoo li lwm lub ntsaws. Qhov txawv yog qhov tshwm simtom qabnws txoj haujlwm tiav lawm. Koj twj ib qho kua tshwj xeeb (piv txwv li, dej ntsev lossis kua qaub) lossis tsuas yog tos kom cov kua dej hauv qhov dej pib ua kom cov txheej txheem yaj.
• Tus yuam sij sib txawv: Tsis tas yuav muaj kev cuam tshuam rau kev tshem tawm.Lub ntsaws yeej ploj mus ntawm nws tus kheej, tawm hauv ib qhoqhov dej qhib.
• Tshem Tawm:Nwsyajtshuaj lom neeg dhau lub sijhawm teem tseg (piv txwv li, teev, hnub, lim tiam). Qhov nrawm ntawm kev yaj yog tsim los ntawm cov kua tshuaj thiab qhov kub ntawm qhov hauv qab.
• Zoo Tshaj Plaws Rau:
  • Cov ntawv thov hnyav heevqhov twg kev cuam tshuam (piv txwv li, xa cov hlua khawb) kim heev, muaj kev pheej hmoo, lossis tsis yooj yim sua (piv txwv li, cov qhov dej ntev heev, kev ua tiav hauv qab dej hiav txwv).
  • Qhov dej nrogCov Twj Tso Kua Hluav Taws Xob (ESPs), qhov twg txawm tias cov hmoov me me los ntawm cov plugs sib xyaw ua ke tuaj yeem ua rau lub twj tso kua mis puas tsuaj. Lub plug yaj tsis tawm cov khib nyiab.
  • Cov kev ua tiav "Frac-and-flow" uas cov neeg tsim khoom xav pib tsim khoom tam sim ntawd tom qab tawg yam tsis muaj kev ua haujlwm tho qhov.
