I-Field ye-China's Offshore Multi-layer Heavy Oil Thermal Recovery ifinyelele irekhodi elisha lokukhiqiza nsuku zonke！

Ngomhla ziyi-15 kuZibandlela, umjikelezo wokuqala wokufaka ukushisa uqediwe epulatifomu ye-CEPA yeJinzhou 23-2 Oilfield, insimu yokuqala ye-thermal recovery ye-heavy oil ye-offshore eChina. Lokhu kubonisa ukuthi inqubekela phambili yomjikelezo wokuqala wokufaka ukushisa ezindaweni zokukhiqiza kule nsimu ye-oyili sekwedlule u-90%, kushayela ukukhiqizwa kwansuku zonke kwe-oyili elingamafutha kudlula amatonnes angu-2,000.

Uma kuqhathaniswa nezinkambu zokukhiqiza uwoyela ezibandayo, inqubo yokuthuthukiswa kwezinkambu zokubuyiselwa kwe-thermal ye-oyela esindayo iyinkimbinkimbi kakhulu. Ngemuva kokuphothulwa kwesiteshi ngasinye, kuqala kwenziwa ukukhiqizwa kokuhlola kwe-jet pump. Lapho ukuhamba kwe-oyela esindayo kwehla futhi ukukhiqizwa kwehla, abaphathi bathola i-pump core bese befaka umusi ophakeme ongu-350 degrees Celsius. Ngemuva kwezinyathelo eziningi zokusebenza ezifana nokufaka ukushisa, isigaba sokufaka, kanye nokubuyisela, abaphathi bafaka kabusha i-jet pump core ukuze bakhuphule uwoyela, ngaleyo ndlela bekhulula amandla okukhiqiza kwe-oyela esindayo. Njengoba inqubo yokufaka ukushisa iqhubeka, ukukhiqizwa kwansuku zonke kwe-oyela elingamafutha e-Jinzhou 23-2 Oilfield kuyaqhubeka nokwenyuka.

I-Bohai Oilfield inezinsiza eziningi ze-oyili ezinzima, kanti i-Liaodong Bay iyindawo eyinhloko yokubuyiselwa kwe-oyili ezinzima nge-thermal. Ukulandela uhlaka lwecebo olukhulu lwe "pilot testing, expanded testing, demonstration application, and scaled implementation," i-Engineering Technology and Operations Center ye-Tianjin Branch ye-CNOOC Limited igxile ku-oyili ezinzima ezingajwayelekile. Iphumelelayo ekuthuthukiseni i-oyili yokuqala enkulu yokubuyiselwa kwe-thermal emanzini, i-Luda 21-2 Oilfield, kanye nephrojekthi yokuqala enkulu yokubuyiselwa kwe-thermal emanzini ye-extra-heavy ne-ultra-heavy oil, i-Luda 5-2 North Oilfield, ngokuphumelelayo iguqula izinsiza zibe ukukhiqizwa.

Ukuguqulwa kwezinsiza zamafutha anzima kube amandla okukhiqiza kuqinisekiswe ngempumelelo ngochungechunge lwezithuthukisi kwezobunjiniyela bokubuyisela ukushisa okuhloswe ngezimo zasolwandle. Ubhekene nezinselelo ezimbili ze "zindawo eziyinkimbinkimbi + izinga lokushisa eliphezulu le-350°C" ngesikhathi sokuthuthukiswa kwezigaba zamathangi aqondile eJinzhou 23-2 Oilfield, iBohai Oilfield ithathe izimiso eziyisisekelo zokuthuthukisa ikhwalithi ye-wellbore nokwandisa ukwakhiwa kwamandla okukhiqiza. Le ndlela ibhekane ngempumelelo nezinselelo zokuthuthukiswa okukhulu kwezinsiza zamafutha anzima ezincane ezihlanganisiwe zasolwandle, yehlisa kakhulu isikhathi sokubhoboza nokuphothula.

EJinzhou 23-2 Oilfield, zonke izindawo zokukhiqiza zifeze ubuchwepheshe bokufaka-ukukhiqiza obuhlanganisiwe. Le ndlela ikhulisa kakhulu ukusetshenziswa kwamandla okushisa kwe-steam futhi ikuguqula kube ukusebenza kahle kokukhipha.

Ngokuhamba kweminyaka yokusebenza kwezobunjiniyela eLiaodong Bay nakwezinye izindawo zokukhiqiza uwoyela omncane, uhlelo lobuchwepheshe bokubuyiselwa kokushisa kwe-oyela omncane eBohai Oilfield luye lwanda njalo. Umkhakha wokusetshenziswa uvele wakhula usuka ezindaweni zokugcina amanzi ezisemaphethelweni uye ezindaweni zokugcina amanzi ezisemathunjini, usuka ezindaweni ezincane uye uye ezindaweni ezinkulu nezindaweni ezincane ezihlanganisiwe, futhi usuka ku-oyela omncane ojwayelekile uye ku-oyela omncane ophakeme. Ukufaneleka kohlelo lobuchwepheshe kuqhubeka nokwandisa, futhi ukuvuselelwa kwalo nokuphindaphindwa kuyashesha.

Ukukhipha uwoyela kanye negesi yemvelo akukwazi ukufezeka ngaphandle kwemishini yokuhlukanisa.

Shanghai SAGA Offshore Engineering Co., Ltd., yasungulwa eShanghai ngonyaka ka-2016, iyinkampani yezobuchwepheshe yesimanje ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nensizakalo. Sigxile ekuthuthukiseni imishini yokuhlukanisa nokuhlunga emikhakheni kawoyela, igesi, kanye nepetrochemical. Iphothifoliyo yethu yemikhiqizo ephumelelayo ifaka phakathi ama-hydrocyclones okukhishwa kawoyela/amanzi, ama-desanders ezinsalela ezincane, kanye nezinsiza zokuhlanza ezihlanganisiwe. Sinikeza izixazululo eziphelele ezibekwe phezulu futhi siphinde sinikeze ukulungiswa kwemishini yeqembu lesithathu kanye nezinsizakalo zokuthengisa ngemva kokuthengwa. Siphatha amalungelo amaningi obunikazi futhi sisebenza ngaphansi kwesistimu yokuphatha ye-DNV-GL eqinisekisiwe ye-ISO-9001, ISO-14001, kanye ne-ISO-45001, sinikeza izixazululo ezithuthukisiwe zenqubo, ukuklama komkhiqizo okunembile, ukulandela ngokuqinile izspecifications zobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.

Okwethu ama-cyclone desanders aphezulu, edumelekile ngokuphumelela kwabo okukhulu kokuhlukanisa okungu-98%, bathole ukuqashelwa kubaholi bamandla bamazwe omhlaba. Bakhiwe ngama-ceramics akwazi ukumelana nokugqoka, lezi zinsiza zifeza ukususa okungu-98% kwezingcezu ezincane njenge-0.5 microns emithonjeni yomoya. Le msebenzi ivumela ukuphinda kufakwe igesi ekhiqiziwe ukuze kube nokufudumala okuxubile ezindaweni ezine-permeability ephansi, isixazululo esibalulekile sokwandisa ukuvuselelwa kwe-oyela ezakhiweni ezinzima. Ngakolunye uhlangothi, zingaphatha amanzi akhiqiziwe, zikususa okungu-98% kwezingcezu ezinkulu kune-2 microns ukuze kuphinde kufakwe ngqo, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokufudumala kwamanzi ngenkathi kuncishiswa umthelela kwemvelo.

Umkhiqizo wethu omusha——I-High Efficiency Ultra-Fine Particle Desander iyidivayisi yokuhlukanisa liquid-solid esebenzisa umgomo ophumelelayo we-centrifugal ukuhlukanisa izinto ezingcolile eziphakanyisiwe—njengama-solids emanzini akhiqiziwe, amanzi olwandle, i-condensate, ama-particles amancane emanzini anobukhulu obuphakeme, kanye nopowder ye-catalyst kumareyaktori—kuyavela kumafluid (amanzi, amagesi, noma inhlanganisela yamagasi-namanzi). Ikhishwa kahle ama-particles aqinile anobukhulu obuphansi ku-2 microns (ngokusebenza okungu-98%) noma amancane.

I-High Efficiency Ultra-Fine Particle Desander inikeza ukusebenza kahle kokukhipha isihlabathi, okwazi ukukhipha ama-particulate aqinile afika ku-2 microns. Le mishini inezici ezincane, ayidingi amandla angaphandle noma izithasiselo zamakhemikhali, futhi inempilo yokusebenza engaba yizinyanga eziyi-20. Iphinde inikeze amandla okukhishwa kwesihlabathi ku-inthanethi ngaphandle kwesidingo sokumisa ukukhiqiza.

Iboniswe ezindaweni ezinkulu zomhlaba ezisebenzelwa yi-CNOOC, CNPC, Petronas, nabanye eNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa ezindaweni zokuphuma nezokukhiqiza. Anikeza ukususa okuqinisekisiwe kwezinto eziqinile kusuka kugesi, emanzini aphuma emithonjeni, nasekondensate, futhi abalulekile ekuhlanzeni amanzi olwandle, ukuvikela umjikelezo wokukhiqiza, kanye nezinhlelo zokufaka amanzi/ukukhukhula.

Ngaphezu kwama-desander, i-SAGA inikeza iphakethe lezi teknolojhi zokuhlukanisa ezidumile. Umugqa wethu wemikhiqizo uhlanganisa izinhlelo ze-membrane zokukhipha i-CO₂ emoyeni wemvelo, ama-hydrocyclones okukhishwa uwoyela, izikhungo zokuhlanza eziphumelelayo ezincane (CFUs), futhi ama-hydrocyclones amaningi, ihlinzeka ngezixazululo eziphelele ezimeni ezinzima zezimboni.
