IShayina ithole iSikhala sayo sesixhenxe sezigidi eziyi-100 zamathani kawoyela eBohai Sea！

Ngomhla ziyi-24 kuZibandlela, iChina National Offshore Oil Corporation (CNOOC) imemezele ukutholakala kwesikhala se-oli esisha esingu-100-million-ton emgqeni ophansi weNeogene woMfula iBohai—lesi sikhala se-oli iQinhuangdao 29-6. Lokhu kubonisa impumelelo yesikhala se-oli esingu-100-million-ton esitholakele ngokulandelana emkhakheni weBohai, okuyisisekelo esikhulu sokukhiqiza i-crude oil eChina, kusukela ngo-2019, okuqhubeka kuqinisa izinsiza zokugcina i-oli kanye negesi ezindaweni zasolwandle zezwe.

I-Qinhuangdao 29-6 oilfield itholakala emanzini aphakathi kweBohai Sea, cishe amakhilomitha angama-44 ngasentshonalanga kweJingtang Port. Ibonisa enye i-lithologic oilfield enezigidi eziyi-100 ezitholakele kule ndawo ezinsukwini ezedlule, kulandela ukutholwa okukhulu kwe-Qinhuangdao 27-3 oilfield. Iwells yokutholwa ithole ungqimba oil olungu-66.7 meters futhi yafinyelela ubukhulu obuphelele obungu-1,688 meters. Ukuhlolwa kukhombisa ukuthi le oilfield ingakhiqiza cishe amaton 370 we-crude oil ngosuku ngawodwa, ikhombisa amathuba okucwaninga anethemba.

Kuqondwa ukuthi insimu ye-oyili ye-Qinhuangdao 29-6 etholeka muva nje itholakala emgqeni ophakeme emaphethelweni e-Shijiutuo Uplift. I-Shijiutuo Uplift ibiyindawo eyinhloko yokuhlola ezikhathini zokuqala zokuthuthukiswa kwe-Bohai Oilfield. Uma i-Shijiutuo Uplift ifaniswa nentaba, insimu ye-oyili ye-Qinhuangdao 29-6 izobe itholakala ezinyaweni zayo. Ngokusho kwemigomo ejwayelekile yokuhlola, umgqa ophakeme we-uplift uyindlela edingekayo yokuhamba kwe-oyili negesi ukusuka ezindaweni zomthombo wezindonga ukuya ezindaweni zokuhlanganisa eziphakeme. Nokho, ngenxa yokuntuleka kwezikhala ezinkulu zokuphuma, ama-hydrocarbons avame "ukudlula ngaphandle kokuhlanganisa," okwenza kube nzima ukuhlanganisa ama-hydrocarbon amakhulu. Kusukela ngeminyaka yama-1970, izigaba eziningi zokuhlola ezihlosiwe ezindaweni ezahlukene emgqeni ophakeme we-Shijiutuo Uplift ziye zaphumelela imiphumela enganelisayo.

Ngo-2024, ukutholwa kwe-billion-ton lithologic oilfield Qinhuangdao 27-3 ku-Shijiutuo Uplift kuhlinzeke ngolwazi oluwusizo nolwazi lwezinhlelo zokuhlola i-lithology endaweni. Ngokuhlanganisa idatha yokubhoboza ekhona eningi kanye nemiphumela yokuhlola, abacwaningi be-CNOOC bathole izimbobo eziningi ezincane "ezifihliwe" ze-lithological ngaphakathi kwezindlela zokuhamba kwe-hydrocarbon, baphumelela ukukhombisa amandla okugcina i-hydrocarbon ebhande le-slope kule uplift. Ngokwakha phezu kwalokhu kutholwa, abacwaningi bahlanganise izifundo eziyisisekelo ku-sedimentology nase-geochemistry ukuze bahlonze izindawo zokwandisa i-hydrocarbon, bachaze izinjongo ezicacile, futhi baqhubeke nokubhoboza. Le ndlela ekugcineni yaholela ekutholeni okukhulu kwe-billion-ton lithologic oilfield ebhande le-slope le-Shijiutuo Uplift, naphezu kwezimo zayo ezinzima zokwakheka eziphansi, ezimfushane, nezihambayo.

Umphakathi ofanele ovela kwi-China National Offshore Oil Corporation (CNOOC) uthe i-CNOOC ikhulise ucwaningo ngokuqhubeka kokuhamba kwe-hydrocarbon kanye nezindlela zokuhlanganisa ezindaweni eziphakeme ze-Neogene futhi ifinyelele ezitholakalweni ezibalulekile ngokusebenzisa ubuchwepheshe obusha. Le mpumelelo ibeke inselelo ekuqondeni kwendabuko ukuthi ama-hydrocarbon ezindaweni eziphakeme ajwayele ukuhamba ngaphandle kokuhlanganisa, okwenza kube nzima ukuhlanganisa ngezinga elikhulu. Iphinde ibonise amandla amakhulu okucwaninga ezindaweni eziphakeme ezikhaleni eziphakeme ngaphansi kokusebenza okuqinile kwe-extentional-strike-slip fault.

Isikhala se-oli iQinhuangdao 29-6 yisikhala se-oli se-lithologic esingu-2 billion-ton esitholakele endaweni yokuhlola esiphumelelayo yeShijiutuo Uplift. Lokhu kuveza ngokwengeziwe inani lokuhlola okuhle futhi kuqinisa isisekelo sezinsiza zokwandisa izinsiza zasekhaya kanye nokukhiqiza.

Ukukhishwa kwe-oli kanye negesi yemvelo akukwazi ukufezeka ngaphandle kwemishini yokuhlukanisa.

Shanghai SAGA Offshore Engineering Co., Ltd., yasungulwa eShanghai ngo-2016, iyinkampani yezobuchwepheshe yesimanje ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nezinsizakalo. Sigxile ekuthuthukiseni imishini yokuhlukanisa nokuhlunga ezimbonini ze-oyili, igesi, nezimboni ze-petrochemical. Iphothifoliyo yethu yemikhiqizo ephezulu yokusebenza ifaka phakathi ama-hydrocyclones okukhishwa kwe-oyili/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 kokuthengisa. Siphatha amalungelo obunikazi amaningi 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, ukuhambisana okuqinile nezincazelo zobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.

Okwethu ama-cyclone desanders aphezulu, edumelekile ngephuzu labo lokuhlukanisa elingu-98%, bathole ukuqashelwa kubaholi bamandla bamazwe omhlaba. Bakhiwe ngama-ceramics aphumelelayo anokugqoka, lezi zinsiza zifeza ukususa ama-particles angu-98% anjenge-0.5 microns emoyeni. Le msebenzi ivumela ukujolisa kabusha igesi ekhiqiziwe ukuze kube nokufaka okuxubile ezindaweni ezinezinga eliphansi lokungena, isixazululo esibalulekile sokuthuthukisa ukuvuselelwa kwe-oyela ezakhiweni ezinzima. Ngakolunye uhlangothi, zingaphatha amanzi akhiqiziwe, zikususa ama-particles angu-98% amakhulu kune-2 microns ukuze kube nokujolisa okuqondile, ngaleyo ndlela kukhuphule ukusebenza kahle kokufaka amanzi 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 anokuhamba okuphezulu, kanye nopowder ye-catalyst kumareyaktori—kwezinye iziphuzo (amanzi, amagesi, noma inhlanganisela yegesi-amanzi). Ikhishwa kahle ama-particles aqinile anobukhulu obuphansi kuze kube ngu-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 yimizuzu engama-20. Inikeza ikhono lokukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokumisa ukukhiqiza.

Iboniswe emikhakheni emikhulu yomhlaba ophathwa yi-CNOOC, CNPC, Petronas, nabanye eNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa ezindaweni zokuphuma naku-platforms zokukhiqiza. Anikeza ukususa okuqinisekisiwe kwezinto eziqinile emoyeni, emanzini, nasekondensate, futhi abalulekile ekuhlanzeni amanzi olwandle, ukuvikela umjikelezo wokukhiqiza, kanye nezinhlelo zokufaka amanzi/ukukhukhula.

Ngaphezu kwama-desander, i-SAGA inikeza iphothifoliyo yezobuchwepheshe bokuhlukanisa ezidumile. Umugqa wethu wemikhiqizo uhlanganisa izinhlelo ze-membrane zokukhipha i-CO₂ emoyeni wemvelo, ama-hydrocyclones okwehlisa i-oli, izikhungo zokuhlanza eziphumelelayo ezincane (CFUs), futhi ama-hydrocyclones amaningi, ehlinzeka ngesisombululo esiphelele ezinselelweni ezinzima zemboni.
