Uyini umsebenzi oyinhloko wokuvimbela ukuqhuma?

Ekwakhiweni kokubhoboza uwoyela negesi, ukuze kubhobozwe ngokuphephile ezingqimbeni zikawoyela negesi ezinomfutho ophezulu futhi kugwenywe izingozi zokubhoboza ezingalawuleki, isethi yemishini - idivayisi yokulawula umthombo wokubhoboza - idinga ukufakwa ekhanda lomthombo wokubhoboza. Uma ingcindezi ebhobozeni ingaphansi kwengcindezi yokwakheka, uwoyela, igesi, namanzi ekwakhekeni okungaphansi komhlaba kungena ebhobozeni bese kwakheka ukugcwala noma ukukhahlela. Ezimweni ezimbi kakhulu, ukubhoboza nokuqhuma kwemigodi kungase kwenzeke izingozi zomlilo. Umsebenzi wedivayisi yokulawula umthombo wokubhoboza ukuvala ngokushesha nangokushesha ikhanda lomthombo lapho ukugcwala noma ukukhahlela kwenzeka emthonjeni ukuvimbela izingozi zokuqhuma.

Amadivayisi okulawula imithombo yokubhoboza afaka phakathi: isivikelo sokubhoboza, i-spool, ikhonsoli yokulawula kude, ikhonsoli yokushayela, i-choke and kill manifold, njll. Idivayisi yokulawula imithombo yokubhoboza ihlangabezana nezidingo zobuchwepheshe bokubhoboza, kulula ukuyisebenzisa, futhi ingavala futhi ivule ikhanda lomthombo ngokushesha. Ingalawulwa kukhonsoli yomshayeli werig yokubhoboza noma kukhonsoli ekude ekude nekhanda lomthombo. Idivayisi kumele ibe nokumelana okuthile kwengcindezi futhi ikwazi ukwenza ukubhoboza okulawulwayo, ukubulala kanye nokukhubeka kwamathuluzi okubhoboza. Ngemva kokufaka isivikelo sokubhoboza esijikelezayo, imisebenzi yokubhoboza ingenziwa ngaphandle kokubulala umthombo.

Ama-BOP okubhoboza ngokuvamile angahlukaniswa abe yi-single ram, i-double ram, (annular) kanye nama-BOP ajikelezayo. Ngokwezidingo zokwakheka okubhobozwayo kanye nobuchwepheshe bokubhoboza, izithiyo eziningana zokuvimbela ukubhoboza nazo zingasetshenziswa ngokuhlanganiswa ngesikhathi esisodwa. Kunezinhlobo ezingu-15 zama-BOP okubhoboza akhona. Ukukhetha usayizi kuncike kusayizi we-casing ekwakhiweni kokubhoboza, okungukuthi, usayizi wobubanzi obujwayelekile be-BOP yokubhoboza mkhulu kancane kunobubanzi bangaphandle be-casing coupling eqhutshwa futhi. Ukucindezela kwesivikelo sokubhoboza kusuka ku-3.5 kuya ku-175 MPa, kanye namazinga okucindezela angu-9 esewonke. Umgomo wokukhetha unqunywa ukucindezela okuphezulu kwekhanda lomthombo lapho kuvalwa emthonjeni.
