Cov haujlwm thiab cov ntawv thov ntawm tubing / Casing Couplings
Tubing thiab casing couplings yog indispensable kev sib txuas hauv cov roj drilling thiab ntau lawm, nrog lawv thawj lub hom phiaj thiab kev ua haujlwm pom hauv cov hauv qab no:
1. Kev Txuas Ua Haujlwm
Koom Nrog Tubing / Casing: Lub hom phiaj tseem ceeb ntawm kev txuas yog txuas ob leeg tubing lossis casting ntu, ua cov hlua txuas txuas ntxiv. Threaded kev sib txuas ua kom cov qauv txuas ntxiv thiab kev ncaj ncees.
Txhawb nqa qauv: Cov couplors muab kev txhawb nqa tseem ceeb kom tswj cov kab yeeb nkab ruaj khov raws li downhole siab, siab} kub (HPHT) tej yam kev mob.
2. Sealing Ua Haujlwm
Kua dej tiv thaiv: Threaded kev sib txuas muaj kev muab cov peev txheej sib txuas los tiv thaiv cov roj uas tsis muaj dej (piv txwv li roj av) lossis roj av, tiv thaiv kev nyab xeeb kom ruaj khov.
Txhim Kho Cov Sealing: Coup tshwj xeeb (piv txwv li cov nplhaib sib khi, HPHT Couplings) sib txuas clastic sealing ntsiab rau huab siab / sholrosive ib puag ncig.
3. Load {- Cov kabmob & Kev Nyuaj Siab faib
Downhole nra tsis kam: Couplings withstand axial loads, tom qab compression, thiab tensile rog hauv HPHT cov xwm txheej kom tiv thaiv cov yeeb nkab deformation / tsis ua tiav.
Kev nyuaj siab dispersion: Tsim cov yam ntxwv kev ntxhov siab ntau yam kev ntxhov siab, txo cov kev hais tawm thiab nkees ua rau ncua lub neej zoo.
4. Kev hloov kho kom tau cov dej num zoo
Ntau hom: Txuj ci, semi- hwm, corrosion, thiab ultras {4} {{{4} {{4} {{4 4} {
Cov Kev Siv Tshwj Xeeb: Corrosion -} Tiv thaiv Couplings Suit Sulphur / Ntsev {{1 {{nplua nuj; Ultra - HPHT Couplings chaw nyob ze ib puag ncig.
5.. YEEB NKAB BLISIS Kev Tiv Thaiv
Kev ntxhov siab nyem: Ua ke Taper / Cov Xov Ntsuas Kev Tsim Kho Kom Muaj Kev Nyuaj Siab Cov kev ntxhov siab ntawm cov cag ntoo, txo qis cov yeeb nkab tsis txaus ntseeg thiab cov yeeb nkab.
Kev Txuas Lub Zog: Optimized xov geometry thiab cov ntaub ntawv xaiv txhim kho kev cuam tshuam / tensile tsis kam rau cov dej num zoo.
6. Kev kho siab ncaj ncees
Kev tsiv tsev nyob nruab nrab: Txheem couplings tsim kom cov kua xau- ntawv pov thawj ntawm cov kav dej ciav hlau ntu, tiv thaiv cov kab ke tsis sib haum thiab kev tswj hwm cov xwm txheej zoo.
Kev Nyab Xeeb Drilling: Lawv pab txhawb cov av nkos av nkos ncig thiab phab ntsa zoo nkauj thaum roj / roj tawm.
