Ncig Teb Chaws

 

Ncig Teb Chaws, tseem hu ua expansion sib koom tes los yog sib koom ua ke, yog tsim los siv rau hauv ob qho tib si thiab ntau txoj hlua ua tiav thiab muab lwm txoj hauv kev ntawm kev them nyiaj rau tubing contraction thiab elongation hauv kev txhaj tshuaj thiab pov tseg qhov dej. Nws yog khiav raws li ib feem tseem ceeb ntawm txoj hlua tubing thiab muaj tag nrho cov tubing drift ID uas yog sib xws nrog lwm yam khoom siv tswj downhole. Tom qab packer cov khoom txuam nrog nyob rau hauv qhov chaw, lub expansion sib koom yuav qhib tau. Nyob ntawm daim ntawv thov, kev sib koom ua ke nthuav dav tuaj yeem qhib los ntawm shear pins lossis cov cuab yeej siv hluav taws xob txheem.

CovNcig Teb Chawstej zaum yuav sheared los ntawm nro los yog compression. Lawv kuj tseem tuaj yeem raug txiav thaum pib ua tiav cov haujlwm lossis sab laug rau hauv qhov chaw pinned kom raug txiav ntawm tus nqi uas tau txiav txim siab tom qab. Kev sib koom tes plam tuaj yeem pinned ntawm txhua qhov chaw hauv qhov mob stroke. Qhov kev tso tawm txawv los ntawm tus naj npawb ntawm shear screws.

① Axial txav:

Expansion thiab Contraction: Cov pob qij txha hauv cov pob qij txha tso cai rau kev tswj axial txav, ua kom txoj hlua nthuav dav lossis cog lus hauv kev teb rau qhov kub thiab txias hloov pauv.

Travel Range: Lawv tau tsim nrog ib qho kev mus ncig tshwj xeeb, uas yog qhov siab tshaj plaws uas lawv tuaj yeem nthuav lossis cog lus. Qhov kev hloov pauv hauv qhov ntau yog sib txawv raws li cov xwm txheej tshwj xeeb thiab cov ntawv thov tshwj xeeb, Vigor'staug kev Jointsmuab 5 ft ntawm kev txav.

② Sealing Mechanism:

Dynamic Seals: Cov ntsaws ruaj ruaj zoo yog siv los tswj lub siab ncaj ncees thaum tso cai txav. Cov ntsaws ruaj ruaj no tiv thaiv cov kua dej tawm thiab ua kom ntseeg tau tias kev ua tau zoo nyob rau hauv cov xwm txheej sib txawv.

Seal Durability: Cov ntsaws ruaj ruaj feem ntau yog tsim los ntawm cov khoom siv tiv taus hnav, kub hloov pauv, thiab raug tshuaj lom neeg.

③ Khoom siv thiab kev tsim kho:

High-Strength Materials: Cov ntaub nplaum nplaum yog tsim los ntawm cov ntaub ntawv muaj zog xws li stainless hlau lossis lwm yam corrosion-resistant alloys kom tiv taus qhov hnyav downhole ib puag ncig.

Robust Design: Cov qauv tsim muaj xws li cov yam ntxwv los tswj axial loads, torsional rog, thiab siab sib txawv, kom ntseeg tau tias qhov sib koom ua ke tseem ua haujlwm thiab txhim khu kev qha.

 

 

① Ua kom Thermal Expansion: Los ntawm kev tso cai rau kev tswj kev nthuav dav thiab kev cog lus,Ncig Teb Chawstiv thaiv buckling thiab kev puas tsuaj rau cov tubing los yog casing hlua los ntawm thermal expansion.

② Mitigates Pressure Changes: Lawv pab tswj cov kev hloov ntawm qhov ntev vim qhov hloov pauv siab, txo qhov kev pheej hmoo ntawm kev ua haujlwm tsis zoo thiab ua kom muaj kev ncaj ncees.

③ Txhim kho Wellbore Flexibility: Nws muab qhov kev hloov pauv uas xav tau los kho cov raj lossis cov hlua khi ntev thaum lub sijhawm sib txawv ntawm kev ua haujlwm zoo, xws li drilling, ua tiav, thiab ntau lawm.

④ Txhim kho kev ntseeg tau thiab kev nyab xeeb: Los ntawm kev ua kom haum rau kev txav thiab txo kev ntxhov siab ntawm txoj hlua, Nws txhim kho kev ntseeg tau thiab kev nyab xeeb ntawm kev ua haujlwm zoo.

 

 

① Thermal Wells: Nyob rau hauv lub qhov dej kub los yog cov roj hnyav uas qhov kub thiab txias tshwm sim, Nws yog ib qho tseem ceeb rau kev tswj cov thermal expansion.

② High-Pressure Wells: Lawv tau siv hauv cov qhov dej siab kom haum raws li qhov ntev ntawm kev hloov pauv vim muaj kev hloov pauv siab, tswj kev ncaj ncees.

③ Kev ua haujlwm hauv dej tob: Kev sib koom ua ke yog qhov tseem ceeb hauv qhov dej tob uas cov hlua tubing tuaj yeem ua rau muaj kev txav tseem ceeb vim qhov chaw muaj zog.

④ Ua tiav Systems: Hauv kev ua tiav zoo,Ncig Teb Chawsmuab qhov tsim nyog yooj rau kev teeb tsa packers thiab lwm yam khoom siv downhole kom raug.

 

 

Vigor Drilling sawv tawm vim nws cov chaw tsim khoom lag luam hauv lub xeev, muaj peev xwm R&D muaj peev xwm, thiab cov ntaub ntawv teev tseg ntau dua 2,000 cov haujlwm ua tiav thoob plaws 50+ lub teb chaws. Lub tuam txhab muaj ntau yam khoom siv high-tech patented thiab tswj cov qauv kev tswj xyuas nruj, ua raws li ISO 9001 thiab API specifications.
