Yintoni i-UCBV (iValve yoMjikelo ongenamkhawulo)?

Ivalve yokudlula umjikelo ongenamdayiseti yamacandelo amafutshane anokuvulwa kwaye avalwe amaxesha amaninzi, afakwe ngokubanzi kwiindidi ezikhethekileyo zokomba ezifana nokuqhelaniswa, ukukhawuleza, kunye nokugawulwa kwemithi ngelixa ukomba, onokuvula kunye nokuvala imingxuma yokudlula ngexesha ngokwemiqathango ye-downhole kwimisebenzi ekhethekileyo, ukwandisa ukusebenza kwezixhobo ezikhethekileyo zokomba, ukunceda ukuphucula impumelelo yemveliso, kunye nokunciphisa imingcipheko yokulawula kakuhle.

Kwimisebenzi ye-downhole, efana ne-plug evuzayo, inaliti ye-asidi, i-workover, kunye nokugqitywa, ukusebenza okuphindaphindiweyo kwevalve yokudlula kunokukhusela indibaniselwano yezixhobo zokwemba i-downhole.Ivalve yokudlula umjikelo ongenamdainokunceda ekuphuculeni ukusebenza kakuhle kokusika kumsebenzi wokwandiswa kwamehlo, ukuphucula isantya sokuhamba kwe-annular kwindawo ethe tye kunye nokugrumba kakuhle, kunye nokuphucula amandla okucoca kwicala elingezantsi lodonga lomthombo.

Iinzuzo eziphambili zobugcisa zeumjikelo ongenasiphelo ivelufa yokudlulazezi zilandelayo:

(1) Iyakwazi ukuqaphela imisebenzi ekhethekileyo efana nokungaqhubi kunye nokuplaga, kunye nokunciphisa umjikelo wokugaya;

(2) Ivalve ye-bypass ivala ngokuzenzekelayo xa impompo imisiwe ukunqanda umphumo onokwenzeka wombhobho we-U okanye iingxaki zokulawula umthombo;

(3) Ayikhawulelwanga ngumngxuma wamanzi wezixhobo zomngxuma wezantsi, izixhobo, kunye namasuntswana okomba, kwaye inokuqonda ukufuduswa okuhle kokuhlamba;

4

(5) Inokukhusela ngokufanelekileyo izixhobo ze-downhole kunye nezixhobo zokugaya amandla
