Pa Ogasiti 30, China National Offshore Oil Corporation (CNOOC) idalengeza kuti kuchulukirachulukira kwamafuta aku China kupitilira matani 5 miliyoni. Izi zikuwonetsa mwala wofunikira kwambiri pakugwiritsira ntchito kwakukulu kwaukadaulo waukadaulo wamafuta ochulukirapo akunyanja ndi zida zazikulu, zomwe zikukhazikitsa China kukhala dziko loyamba padziko lonse lapansi kukwaniritsa chitukuko chachikulu chamafuta olemera akunyanja.
Malinga ndi malipoti, mafuta olemetsa pakali pano amatenga pafupifupi 70% yamafuta otsala padziko lonse lapansi, zomwe zimapangitsa kuti ikhale yofunika kwambiri pakuchulukirachulukira kwa mayiko omwe amapanga mafuta. Kwa mafuta olemera kwambiri a viscosity, makampaniwa amagwiritsa ntchito njira zochepetsera kutentha kuti achotse. Mfundo yaikulu imaphatikizapo kubaya nthunzi yotentha kwambiri, yothamanga kwambiri m'madzi kuti mutenthe mafuta olemera kwambiri, motero kuchepetsa kukhuthala kwake ndikusandulika kukhala "mafuta opepuka" osavuta kuchotsa.

Mafuta olemera ndi mtundu wamafuta osakanizidwa omwe amadziwika ndi kukhuthala kwakukulu, kachulukidwe kwambiri, kusayenda bwino kwamadzimadzi, komanso chizolowezi cholimba, zomwe zimapangitsa kuti zikhale zovuta kuchotsa. Poyerekeza ndi minda yamafuta akunyanja, nsanja zakunja zili ndi malo ochepa ogwirira ntchito ndipo zimawononga ndalama zambiri. Kuchulukanso kwamafuta ochulukirapo kumabweretsa zovuta ziwiri pankhani ya zida zaukadaulo komanso kuthekera kwachuma. Izi zimazindikirika ngati vuto lalikulu laukadaulo ndi zachuma pamakampani opanga mphamvu padziko lonse lapansi.
Ntchito zobwezeretsa mafuta ochulukirapo ku China zimakhazikika ku Bohai Bay. Malo angapo obwezeretsa mafuta oyaka akhazikitsidwa, kuphatikiza ma projekiti a Nanpu 35-2, Lvda 21-2, ndi Jinzhou 23-2. Pofika chaka cha 2025, kupanga kwapachaka kuchokera kuchira kwamafuta kudapitilira kale matani 1.3 miliyoni, zomwe zikuyembekezeka kukwera mpaka matani 2 miliyoni.

Kuti agwiritse ntchito moyenera komanso mwachuma nkhokwe zamafuta olemera, CNOOC yapitiliza kufufuza zasayansi ndiukadaulo, ndikuyambitsa chiphunzitso cha "kuwerengera kotsika, kutulutsa kwakukulu" kwachitukuko chamafuta. Kampaniyo yatengera njira yopangira chitsime chotalikirapo chomwe chimadziwika ndi jakisoni wothamanga kwambiri komanso kupanga, mawonekedwe a nthunzi wapamwamba kwambiri, komanso kupititsa patsogolo ma synergistic kudzera m'madzi otentha amitundu yambiri.
Pobaya jekeseni wochuluka wa calorific wowonjezera ndi mpweya wosiyanasiyana ndi mankhwala, komanso mothandizidwa ndi luso lapamwamba lokweza mphamvu, njirayi imawonjezera kwambiri kupanga kwa chitsime. Yathana bwino ndi zovuta zomwe zakhalapo kwanthawi yayitali pakuchira kwamafuta, monga kuchepa kwapang'onopang'ono komanso kutayika kwa kutentha kwakukulu, motero zikuwonjezera kuchuluka kwamafuta olemera.
Malinga ndi malipoti, kuthana ndi zovuta downhole mikhalidwe kutentha mkulu ndi kuthamanga mkulu mafuta matenthedwe kuchira ntchito, CNOOC bwinobwino anayamba dziko kutsogolera Integrated jekeseni zipangizo zotha kupirira madigiri 350 Celsius. Kampaniyo yapanga pawokha makina opangira ma jekeseni otenthetsera ophatikizana komanso ogwira ntchito bwino, makina owongolera chitetezo chapansi panthaka, ndi zida zowongolera mchenga zokhalitsa. Kuphatikiza apo, yapanga ndi kumanga pulatifomu yoyamba padziko lonse lapansi ya jakisoni wotenthetsera—“Thermal Recovery No.1″—kudzaza mpata waukulu wa zida za ku China zogwiritsa ntchito mafuta olemetsa kwambiri a kunyanja.

Ndi kupititsa patsogolo ukadaulo waukadaulo wowongolera matenthedwe komanso kutumizidwa kwa zida zofunikira, ntchito yopangira zida zopangira mafuta ochulukirapo ku China kwafulumizitsa kwambiri, zomwe zapangitsa kuti ntchito yosungiramo madzi ikhale yopambana. Mu 2024, mafuta ochulukirapo aku China adapitilira matani miliyoni kwa nthawi yoyamba. Pakadali pano, kuchuluka kwachulukidwe kwapitilira matani mamiliyoni asanu, zomwe zapangitsa kuti mafuta olemera ayambirenso m'madera akunyanja.
Mafuta olemera amadziwika ndi kachulukidwe kwambiri, kukhuthala kwakukulu, komanso kuchuluka kwa resin-asphaltene, zomwe zimapangitsa kuti madzi asawonongeke. The m'zigawo mafuta olemera Iwo anganyamule kuchuluka kwa mchenga wabwino olimba ndi mafuta olemera yotengedwa ndi zotsatira zovuta kulekana pa dongosolo kunsi kwa mtsinje, kuphatikizapo opangidwa madzi mankhwala kapena osauka opangidwa madzi khalidwe kutaya. Pogwiritsa ntchito zida zolekanitsa zamkuntho za SJPEE, tinthu tating'onoting'ono tomwe titha kukula mpaka ma serval microns amachotsedwa pamakina akuluakulu ndikupanga kupanga bwino. .
Pokhala ndi ma patent angapo odziyimira pawokha aukadaulo, SJPEE imatsimikiziridwa pansi pa DNV/GL-recognized ISO 9001, ISO 14001, ndi ISO 45001 kasamalidwe kabwino ndi kachitidwe kantchito yopanga. Timapereka mayankho okhathamiritsa, kapangidwe kake kazinthu, kutsata mosamalitsa zojambula pakumanga, komanso maupangiri ogwiritsira ntchito pambuyo popanga kwa makasitomala m'mafakitale osiyanasiyana.
Zathuzida zapamwamba za cyclone desanders, ndi luso lawo lolekanitsa la 98%, adayamikiridwa kwambiri ndi zimphona zambiri zamphamvu zapadziko lonse lapansi. cyclone desander yathu yamphamvu kwambiri imagwiritsa ntchito zida zapamwamba za ceramic (kapena zotchedwa, anti-kukokoloka) zida, zomwe zimachotsa mchenga mpaka ma microns 0.5 pa 98% pochiza gasi. Izi zimapangitsa kuti gasi wopangidwa kuti alowe m'malo osungiramo mafuta ocheperako omwe amagwiritsa ntchito kusefukira kwa gasi wosokonekera ndikuthana ndi vuto la kasungidwe kocheperako komanso kumathandizira kuchira kwamafuta. Kapena, imatha kuthira madzi opangidwa pochotsa tinthu ting'onoting'ono ta 2 microns pamwamba pa 98% kuti ibayidwenso mwachindunji m'malo osungiramo madzi, kuchepetsa kuwonongeka kwa chilengedwe chakunyanja ndikukulitsa zokolola zam'munda wamafuta ndiukadaulo wa kusefukira kwamadzi.
SJPEE's desanding hydrocyclone yayikidwa pamapulatifomu opangira mafuta ndi gasi omwe amagwiritsidwa ntchito ndi CNOOC, CNPC, Petronas, komanso ku Indonesia ndi Gulf of Thailand. Amagwiritsidwa ntchito pochotsa zolimba kuchokera ku gasi, madzi amchere, kapena condensate, ndipo amagwiritsidwanso ntchito pazinthu monga kuchotsa madzi a m'nyanja olimba, kubwezeretsa kupanga, jekeseni wa madzi, ndi kusefukira kwa madzi kuti apititse patsogolo mafuta.
Zachidziwikire, SJPEE imapereka zambiri kuposa kungotaya mtima. Zogulitsa zathu, mongakulekana kwa membrane - kukwaniritsa CO₂ kuchotsa mu gasi wachilengedwe, kuwononga hydrocyclone, mawonekedwe apamwamba a compact flotation unit (CFU),ndimultichamber hydrocyclone, onse ndi otchuka kwambiri.
