API 5ST CT80 Coiled Tubing
Coiled tubing thiab nws cov khoom siv ua haujlwm yog hu ua "universal ua haujlwm tshuab", thiab tuaj yeem muab faib ua txoj hlua coiled (xws li cov hlua ua haujlwm zoo thiab cov hlua tshaj tawm) thiab coiled kab yeeb nkab raws li kev siv.
Cov hlua ua haujlwm zoo tsuas yog siv rau hauv cov roj nqa induced txau cov kua dej, dej yaug thiab ntxuav, blunt xuab zeb thiab ntsaws kev daws teeb meem, tshem tawm cov av, hloov av, acidification, khaws cia, tawg thiab tag nrho ntau tshaj 20 hom kev txiav, ua haujlwm tshaj, drilling thiab ua kom tiav kev ua haujlwm zoo.
Txoj hlua nrawm feem ntau yog siv rau hauv cov kua dej ntau ntxiv ntawm cov dej permeability tsawg, kuj tuaj yeem hloov cov tubing ncaj qha siv raws li txoj hlua tiav.
Coiled kab yeeb nkab tsuas yog siv nyob rau hauv qhov chaw sib sau ua ke cov yeeb nkab kab hauv av roj teb thiab sib sau cov yeeb nkab kab ntawm ntug dej hiav txwv drilling platform.
Txuj: API 5ST
Coiled tubing muaj xws li downhole ua hauj lwm tubing, thiab velocity tubing
Max.Ntev: 8000m
Nta:
> Tsis muaj xov txuas, kev ua haujlwm siab thiab kev ruaj ntseg
> Kev txav ceev thiab kev teeb tsa, kev ua haujlwm siab
> Tsis nres ua haujlwm nrog lub peev xwm loj-kev muaj peev xwm
> Tsawg qhov chaw ua haujlwm xav tau
> Tus nqi ua haujlwm raug txo qis heev
