Ngomhla wama-30 ku-Agasti, i-China National Offshore Oil Corporation (CNOOC) yabhengeza ukuba imveliso yase-China eyongezelelekileyo ye-oyile enzima yokubuyisela ubushushu idlule kwi-5 yezigidi zeetoni. Oku kuphawula ilitye elibalulekileyo ekusetyenzisweni kwenkqubo yobuchwepheshe bokubuyisela ioyile enzima elunxwemeni kunye nezixhobo eziphambili, kumiselwa iChina njengelizwe lokuqala lehlabathi ukuphumeza uphuhliso olukhulu lokuphinda kuphuculwe ubushushu be-oyile elunxwemeni.
Ngokweengxelo, i-oyile enzima ngoku ithatha malunga ne-70% yemithombo ye-petroleum eseleyo yehlabathi, okwenza kube yinto ephambili ekugxilwe kuyo ekunyuseni kwemveliso kumazwe avelisa ioli. Kwioli enzima ye-viscosity, ishishini ngokuyinhloko lisebenzisa iindlela zokubuyisela ukushisa ukuze kukhishwe. Umgaqo ongundoqo ubandakanya ukutofa ubushushu obuphezulu, ubushushu obuphezulu kwi-reservoir ukutshisa ioli enzima, ngaloo ndlela inciphisa i-viscosity yayo kwaye iyiguqule ibe yi-mobile, "oyile elula" ekhutshwa lula.

I-oyile enzima luhlobo lwe-oyile ekrwada ephawulwa ngokuba ne-viscosity ephezulu, ukuxinana okuphezulu, ukungamanzi kakuhle, kunye nokuthanda ukuqina, nto leyo eyenza kube nzima kakhulu ukuyikhupha. Xa kuthelekiswa neendawo zeoyile eziselunxwemeni, amaqonga angaphesheya anendawo enyiniweyo yokusebenza kwaye aneendleko eziphezulu kakhulu. Ukubuyiswa kwe-oyile enzima ngokomlinganiselo omkhulu kuzisa imingeni emibini ngokwezixhobo zobugcisa kunye nokuhlala kakuhle kwezoqoqosho. Oku kwamkelwa ngokubanzi njengomngeni omkhulu wobugcisa noqoqosho kushishino lwamandla ehlabathi.
Imisebenzi yaseTshayina ekude nonxweme yokubuyisela i-oyile enzima igxile ikakhulu kwi-Bohai Bay. Iindawo ezininzi ze-oyile zokubuyiswa kwe-thermal ziye zasekwa, kuquka i-Nanpu 35-2, i-Lvda 21-2, kunye neeprojekthi ze-Jinzhou 23-2. Ngo-2025, imveliso yonyaka ukusuka ekubuyiselweni kwe-thermal sele idlulile kwi-1.3 yezigidi zeetoni, kunye nesiphumo sonyaka opheleleyo siqikelelwa ukuba sinyuke siye kwi-2 yezigidi zeetoni.

Ukuxhaphaza ngokufanelekileyo nangoqoqosho oovimba be-oyile enzima, i-CNOOC iqhubekile nokuqhuba uphando lwezenzululwazi kunye nokwenziwa kwezinto ezintsha zobuchwepheshe, ivula ithiyori “yokubala okuphantsi, iziphumo eziphezulu” ithiyori yophuhliso lokubuyisela ubushushu. Inkampani yamkele imodeli yophuhliso lwesithuba esikhulu esinesithuba esikhulu esiphawulwa sisitofu esinobunzima obuphezulu kunye nemveliso, umgangatho womphunga ophezulu, kunye nokuphucula i-synergistic ngokusebenzisa ulwelo olushushu olunamacandelo amaninzi.
Ngokufaka i-steam ye-calorific ephezulu eyongezwa ngeegesi ezahlukeneyo kunye neekhemikhali zeekhemikhali, kunye nokuxhaswa ngeteknoloji yokuphakamisa i-volume ephezulu, le ndlela iphucula kakhulu imveliso nganye. Isombulule ngempumelelo imiceli mngeni yexesha elide ekubuyiseni ubushushu, njengemveliso ephantsi kunye nelahleko enkulu yobushushu, ngaloo ndlela inyusa ngokuphawuleka izinga lokubuyiswa kwe-oyile enzima.
Ngokweengxelo, ukujongana neemeko ezintsonkothileyo zobushushu obuphezulu kunye noxinzelelo oluphezulu kwimisebenzi yokubuyisela i-oyile enzima, i-CNOOC iphuhlise ngempumelelo izixhobo zokuvelisa iinaliti ezidibeneyo zehlabathi ezikwaziyo ukumelana ne-350 degrees Celsius. Inkampani iye yaphuhlisa ngokuzimeleyo iinkqubo zokutofa kwe-thermal compact kunye nesebenzayo, iinkqubo zokulawula ukhuseleko lwe-downhole, kunye nezixhobo zokulawula isanti ezihlala ixesha elide. Ngaphaya koko, iye yayila yaza yakha iqonga lehlabathi lokuqala lehlabathi lokutofa i-thermal—“Thermal Recovery No.1″—izalisa umsantsa obalulekileyo kwizixhobo zaseTshayina zokubuyisela i-oyile enzima elunxwemeni.

Ngophuculo oluqhubekayo lwenkqubo yetekhnoloji yokubuyisela ubushushu kunye nokuthunyelwa kwezixhobo eziphambili, ukwakhiwa komthamo wemveliso ye-offshore ye-oyile enzima yokubuyisela ukufudumala kwe-oyile e-China kuye kwakhawuleziswa kakhulu, okukhokelela ekuphuhlisweni kwedama. Ngo-2024, imveliso ye-oyile eshushu engaphaya konxweme yaseTshayina igqithise kwisigidi seetoni okokuqala. Ukuza kuthi ga ngoku, imveliso eyongezelelekileyo igqithise kwizigidi ezihlanu zeetoni, iphumeza ukubuyisela ubushushu obukhulu kwi-oyile enzima kwiindawo ezingaselunxwemeni.
Ioli enzima ibonakala ngokuxinana okuphezulu, i-viscosity ephezulu, kunye nomxholo ophezulu we-resin-asphaltene, obangela ukungahambi kakuhle kwamanzi. Ukutsalwa kwe-oyile enzima Kuya kuthwala isixa esikhulu sesanti ecolekileyo eqinileyo kunye ne-oyile enzima ekhutshiweyo kunye neziphumo ezinzima zokwahlula kwinkqubo esezantsi yomlambo, kubandakanywa ukucocwa kwamanzi avelisiweyo okanye umgangatho ophantsi wamanzi ovelisiweyo ukuze ulahlwe. Ngokusebenzisa izixhobo ze-SJPEE eziphezulu ezisebenzayo zokwahlula i-cyclone, la maqhekeza amahle obungakanani ukuya kwi-serval microns iya kususwa kwinkqubo yenkqubo ephambili kwaye yenze imveliso ngokutyibilikayo. .
Ngamalungelo awodwa omenzi wepropathi enomgangatho ophezulu wokuqonda, i-SJPEE iqinisekiswa phantsi kwe-DNV/GL-iqatshelwe i-ISO 9001, ISO 14001, kunye ne-ISO 45001 yolawulo lomgangatho kunye neenkqubo zenkonzo yokuvelisa. Sinikezela ngezisombululo zenkqubo ephuculweyo, uyilo lwemveliso oluchanekileyo, ukubambelela ngokungqongqo kwimizobo yoyilo ngexesha lolwakhiwo, kunye neenkonzo zokubonisana zokusetyenziswa kwasemva kwemveliso kubathengi kuwo wonke amashishini ahlukeneyo.
Yethui-desanders ye-cyclone esebenza kakuhle, ngobuchule babo bokwahlukana obumangalisayo be-98%, bazuze udumo olukhulu kwiingxilimbela ezininzi zamandla zamazwe ngamazwe. I-cyclone desander yethu esebenza kakuhle kakhulu isebenzisa i-ceramic ekwazi ukumelana nokunxiba (okanye ebizwa ngokuba, i-anti-rosion kakhulu) imathiriyeli, ifezekisa impumelelo yokususa isanti ukuya kuthi ga kwi-0.5 microns kwi-98% yonyango lwegesi. Oku kuvumela irhasi eveliswayo ukuba ifakwe kwiindawo zokugcina i-oyile ekwazi ukungena kancinci ezisebenzisa izandyondyo zerhasi ezixubeneyo kwaye isombulule ingxaki yophuhliso lwamadama okungena amanzi aphantsi kwaye iphucula ngokubonakalayo ukubuyiswa kwe-oyile. Okanye, inokunyanga amanzi avelisiweyo ngokususa amasuntswana e-2 microns ngaphezulu kwe-98% ukuze iphinde ifakwe ngokuthe ngqo kwimithombo yamanzi, ukunciphisa impembelelo yokusingqongileyo yaselwandle ngelixa iphucula imveliso ye-oyile kunye nobuchwepheshe bokukhukula kwamanzi.
I-SJPEE's desanding hydrocyclone ifakwe kwi-wellhead kunye namaqonga emveliso kuwo wonke amasimi e-oyile kunye negesi aqhutywa yi-CNOOC, i-CNPC, i-Petronas, kunye ne-Indonesia kunye ne-Gulf yaseThailand. Zisetyenziselwa ukususa izinto eziqinileyo kwirhasi, ulwelo lwamanzi, okanye i-condensate, kwaye zikwasetyenziswa kwiimeko ezinje ngokususwa okuqinileyo kwamanzi olwandle, ukubuyiswa kwemveliso, inaliti yamanzi, kunye nokukhukula kwamanzi ukuze kuphuculwe ukubuyiswa kweoyile.
Ewe kunjalo, i-SJPEE ibonelela ngakumbi kune-desanders nje. iimveliso zethu, ezifanaukwahlukana kwe-membrane - ukufezekisa ukususwa kwe-CO₂ kwigesi yendalo, deoiling hydrocyclone, iyunithi yomgangatho ophezulu wokuqukuqela (CFU), kwayei-hydrocyclone enamagumbi amaninzi, zonke zithandwa kakhulu.
