Ukuqonda imisebenzi yeevalvu eziminxayo kwizixhobo zokulawula kakuhle
Kwizixhobo zolawulo lomthombo,iivalve eziminxa idlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kwimithombo yeoli nerhasi. Ezi zivalo zenzelwe ukulawula uxinzelelo kunye nokuhamba kwamanzi, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwemisebenzi yokomba. Kule bhlog, siza kujonga ngakumbi ukuba njaniiivalve eziminxaumsebenzi kunye nokubaluleka kwawo kuizixhobo zokulawula kakuhle.
Iivalve zokukrwitshwa zidla ngokuxhonywaumthi weKrismesi , icandelo lequla elibonelela ngolawulo kunye nokufikelela kwiqula. Umsebenzi ophambili wesivalo sokuminxa kukucutha ukuhamba kolwelo kwiqula leoli, ngokwenjenjalo kulawula uxinzelelo kunye nokuthintela nakuphi na ukuvuthela okunokwenzeka okanye ukukhutshwa okungalawulekiyo kweehydrocarbons. Oku kubaluleke kakhulu ngexesha lokugaya, ukugqitywa kunye nokusebenza kwemveliso, apho uxinzelelo lwamanzi kunye namazinga okuhamba kufuneka alawulwe ngononophelo ukuqinisekisa ukhuseleko lwabasebenzi kunye nokuthembeka kakuhle.
Umgaqo osebenzayo we-valve ye-throttle ibandakanya ukusetyenziswa kwe-orifice ehlengahlengiswayo ukulawula ukuhamba kwamanzi. Ngokulungelelanisa ukuvuleka kwevalve, abaqhubi banokulawula ukuhamba kunye noxinzelelo lolwelo ukulawula ngokuchanekileyo iimeko ze-wellbore.Ivalve yokukrwitshainokusebenza ngesandla okanye ixhotyiswe ngolawulo oluzenzekelayo, kuxhomekeke kwiimfuno ezithile zomthombo kunye nokusebenza kokugaya.
Ukongeza ekulawuleni ukuqukuqela kwamanzi, iivalve eziminxayo nazo zidlala indima ephambili ekulawuleni kakuhle i-backpressure. Ngexesha lemisebenzi ethile, efana nokuvavanya kakuhle okanye ukuveliswa, i-backpressure ethile kufuneka igcinwe ukuze kulungiswe ukuhamba kwamanzi kunye nokuqinisekisa ingqibelelo yendawo yokugcina amanzi. Iivalve ze-Throttle zinceda ukufezekisa kunye nokugcina uxinzelelo olufunekayo emva kokuveliswa ngokufanelekileyo kunye nokulawulwa kwe-reservoir.
Ukongeza, iivalve zokuminxa zenzelwe ukumelana neemeko ezinzima ezidibana nazo ngexesha lolawulo lomthombo. Zenziwe ngezixhobo eziphezulu zamandla kwaye zixhotyiswe ngamatywina kunye nokupakisha ukuqinisekisa ukusebenza okuthembekileyo kwiindawo ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu. Olu lwakhiwo lunzima lubalulekile ekuqinisekiseni ukhuseleko kunye nemfezeko yezixhobo zolawulo lomthombo, ngakumbi ngexesha lemisebenzi ebalulekileyo efana nokulawula iqula kunye nokuthintela ukuvuthela.
Isishwankathelo, iivalve zokuminxa ziyinxalenye ebalulekileyo yezixhobo zokulawula umthombo kwaye zidlala indima ebalulekileyo ekulawuleni ukuhamba kolwelo kunye nokulawula uxinzelelo lweoyile kunye negesi. Ukukwazi kwabo ukulawula ukuhamba, ukunyanzeliswa kwe-backpressure kunye ne-fluid dynamics kubalulekile ekuqinisekiseni ukhuseleko kunye nokusebenza kakuhle kokomba, ukugqitywa kunye nemisebenzi yokuvelisa. Ukuqonda ukusebenza kunye nokubaluleka kweevalve zokuklikha kubalulekile kuye nawuphi na umdlali kwishishini leoli kunye negesi njengoko zibalulekile ekugcineni intembeko yomthombo kunye nokuqinisekisa impumelelo yokusebenza kokomba.
