Insimu kawoyela yase-Búzios eBrazil ifinyelele umkhiqizo wansuku zonke oyizigidi eziyi-1.2 zamabhareli, ishaya irekhodi eliphezulu!

Muva nje, insimu yaseBúzios eBrazil—umthombo omkhulu kakhulu emhlabeni wamafutha angaphansi kolwandle ajulile, lapho i-CNOOC ibambe iqhaza futhi inamasheya—ilethe izindaba ezinhle. I-Petrobras imemezele ukuthi insimu yaseBúzios isifinyelele umkhiqizo wansuku zonke oyizigidi eziyi-1.2 zamabhareli, okubeka umkhawulo omusha womlando. Ukwenyuka okuqhubekayo komkhiqizo walomthombo we-pre salt wezinga lomhlaba akugcini nje ngokuqinisekisa amandla amakhulu e-ultra deepwater carbonate reservoirs, kodwa futhi kubeka izidingo eziphakeme ekusebenzeni kahle, ekuphepheni, nasekuhlakanipheni.

Ngokuphendula kule nselelo, i-CNOOC, kanye nesikhungo saseBrazil i-CESAR kanye ne-Federal University of Alagoas (UFAL), baqalise ngokusemthethweni iphrojekthi ye-digital twin egxile ekuthuthukiseni ukusebenza kokumba nokuqedela emkhakheni waseBúzios. Ngokusho kwe-BNAmericas, le phrojekthi iyingxenye yezimali eziphoqelekile zocwaningo nokuthuthukiswa ezidingwa yi-Petrobras kanye ne-National Agency of Petroleum, Natural Gas and Biofuels (ANP). Ngeminyaka engu-36 ubude, izimali ezinikezwe i-CESAR yodwa zifinyelela ku-18.5 million reais (cishe u-US$3.61 million).

UTiago Bockholt, umphathi webhizinisi e-CESAR, uthe lo msebenzi uhlose ukuthuthukisa amamodeli obuhlakani bokwenziwa ukuze asekele imisebenzi yemithombo yokukhiqiza, ngokuhlela inani elikhulu ledatha yokusebenza ukuze anikeze amathimba ezobuchwepheshe ukuhlaziya okubikezelayo nezincomo. Ekuqalisweni kwalo msebenzi, umkhiqizo wensimu wawusanda kweqa izigidi eziyi-1.1 zamabhareli, futhi manje usugxume wafinyelela ezigidini eziyi-1.2—okwenza ukuthi ubunjalo bayo obubheke phambili kanye nokuphuthuma kube sobala.

Kulesi sikhathi somkhiqizo orekhoda amarekhodi, lokhu kutshalwa kwezimali kobuchwepheshe okubonakala kuncane empeleni kukhombisa ushintsho olujulile lwe-CNOOC emkhakheni wayo wamanzi ajulile e-Brazil nasemhlabeni wonke—usuka ekulandeleni abaqhubi ngokungenzi lutho ukuya ekwakheni ngokuqhubekayo amakhono obuchwepheshe ayisisekelo emanzini ajulile kakhulu e-pre-salt, futhi ubeka isisekelo esiqinile sedijithali sokusebenza okuzimele kwesikhathi esizayo.

Ukukhishwa kukawoyela negesi yemvelo akunakufezwa ngaphandle kwemishini yokuhlukanisa.

I-SAGA Offshore Engineering Co., Ltd. yaseShanghai, eyasungwa eShanghai ngo-2016, iyinkampani yesimanje yezobuchwepheshe ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nesevisi. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga embonini kawoyela, igesi, namakhemikhali aphethiloli. Iphothifoliyo yethu yemikhiqizo enomphumela ophakeme ihlanganisa ama-hydrocyclones okukhipha uwoyela/amanzi, ama-desanders ezinhlayiyana ezingama-micron, kanye namayunithi e-compact flotation. Sihlinzeka ngezixazululo eziphelele ezigxilisiwe futhi sinikeza nezinsiza zokulungisa kabusha imishini yezinkampani zangaphandle kanye nezinsiza zangemva kokuthengisa. Siphethe amalungelo obunikazi amaningi futhi sisebenza ngaphansi kohlelo lokuphatha lwe-DNV-GL olugunyaziwe lwe-ISO-9001, ISO-14001, kanye ne-ISO-45001, siletha izixazululo ezincono kakhulu zenqubo, ukuklama okunembile komkhiqizo, ukuhambisana ngokuqinile nezimfuneko zobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.

I-izihlanzi ezinamandla ezi-cyclone, aziwa ngezinga elihle kakhulu lokuhlukanisa elingu-98%, zithole ukuqashelwa ngabaholi bamandla emhlabeni jikelele. Zakhiwe ngezinto ezithuthukisiwe ezingama-ceramics ezingagugi, lezi zingxenye zikwazi ukususa ama-particle angu-98% acishe abe ngu-0.5 microns emgqeni wegesi. Lokhu kukwazi kwenza kube nokwenzeka ukuthi igesi ekhiqiziwe iphinde ifakwe ukuze kube nokuhlangana okuhle emithonjeni ene-permeability ephansi, okuyisixazululo esibalulekile sokuthuthukisa ukutholwa kukawoyela ezindaweni eziyinselele. Ngokunye, zingahlanza amanzi akhiqiziwe, zisuse ama-particle angu-98% amakhulu kuno-2 microns ukuze aphinde afakwe ngqo, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwe-water-flood kuyilapho kuncishiswa umthelela emvelweni.

Umkhiqizo wethu omusha—I-High Efficiency Ultra-Fine Particle Desander iyithuluzi lokuhlukanisa uketshezi nokuqinile elisebenzisa umgomo ophakeme we-centrifugal ukuze ihlukanise izinto ezingcolile ezimisiwe—ezifana nezinto eziqinile emanzini akhiqiziwe, emanzini olwandle, emanzini ajiyile, izinhlayiya ezincane eziketshezini olunamandla okubambelela aphezulu, kanye nempuphu ye-catalyst kuma-reactor—ezintweni eziwuketshezi (uketshezi, amagesi, noma izingxube zegesi noketshezi). Isusa ngempumelelo izinhlayiya eziqinile ezinobukhulu obufinyelela ku-2 microns (ngokusebenza kahle okungu-98%) noma ezincane kakhulu.

I-High Efficiency Ultra-Fine Particle Desander iletha ukusebenza kahle okuphezulu ekususeni isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifinyelela ku-2 microns. Umshini unendawo encane, awudingi amandla angaphandle noma izithasiselo zamakhemikhali, futhi unempilo yokusebenza ecishe ibe yiminyaka engu-20. Unamandla okukhipha isihlabathi ngenkathi usebenza ngaphandle kwesidingo sokumisa ukukhiqiza.

Izinhlaka zokuhlanza i-sand ze-SAGA ezihlonishwe emikhakheni emikhulu yomhlaba wonke eqhutshwa yi-CNOOC, CNPC, Petronas, nezinye eNingizimu-mpumalanga ye-Asia, zisetshenziswa ezinkundleni zomthombo kanye nezinkundla zokukhiqiza. Zihlinzeka ngokususwa okuqinisekile kwezinto eziqinile kugesi, uketshezi lomthombo, kanye ne-condensate, futhi zibalulekile ekuhlanzweni kwamanzi olwandle, ekuvikelweni komfula wokukhiqiza, kanye nezinhlelo zokujova/ukugcwaliswa kwamanzi.

Ngaphandle kwezihlanzi zesand, i-SAGA inikeza uhlu lwezindlela zokuhlukanisa ezihlonishwayo. Umkhiqizo wethu uhlanganisa izinhlelo ze-membrane zokususa i-CO₂ kugesi wemvelo, ama-hydrocyclone okukhipha uwoyela, amayunithi okuntanta ahlanganisiwe asebenza kahle kakhulu (CFUs), ukususa isihlabathi kugesi we-shale, Iphakethe lokususa amanzi nge-cyclonic elihlanganisa nokwelashwa kwamanzi akhiqiziwe, kanye ama-hydrocyclone anamakamelo amaningi, okuhlinzeka ngezixazululo eziphelele ezinseleleni ezinzima zomkhakha.
