Musi waKurume 31, CNOOC yakazivisa kuwanikwa kweChina kwenzvimbo yemafuta yeHuizhou 19-6 ine matura anodarika zana remamiriyoni ematani kumabvazuva kweSouth China Sea. Izvi zvinocherekedza nzvimbo yekutanga yeChina yakabatanidzwa yemafuta ekumahombekombe munzvimbo yakadzika-yakadzika-yakadzika matombo ematombo, zvichiratidza kugona kukuru kwekuongorora munzvimbo dzakadzika dzemahombekombe egungwa rehydrocarbon.
Inowanikwa muHuizhou Sag yePearl River Mouth Basin, anenge makiromita zana nemakumi manomwe kubva kumahombekombe kubva kuShenzhen, nzvimbo yemafuta yeHuizhou 19-6 inogara paavhareji yemvura yakadzika yemamita zana. Miedzo yekugadzira yakaratidza kubuda kwemazuva ese kwe413 madhiramu emafuta asina kuchena uye 68,000 cubic metres egasi chaiwo patsime. Kuburikidza nekuedza kwakasimba kwekuongorora, munda wakawana nzvimbo dzakasimbiswa dze geological reserve dzinodarika zana remamiriyoni ematani emafuta akaenzana.
Iyo "Nanhai II" yekuchera papuratifomu iri kuita mabasa ekuchera muHuizhou 19-6 nzvimbo yemafuta yemvura.
Mumafuta ekumahombekombe egungwa nekuongorora gasi, maumbirwo ane hudzamu hwekuvigwa anodarika 3,500 metres akaiswa tekinoroji semadziva akadzika, nepo iwo anopfuura 4,500 metres akaiswa muchikamu chemvura yakadzika. Kuongorora munzvimbo idzi dzakadzika-dzakadzika dzemugungwa kunopa zvipingamupinyi zveinjiniya, zvinosanganisira kunyanyisa kutonhora/kudzvanya-kudzvanya (HT/HP) uye kuomarara kwemvura.
Clastic rock formations, ichiri kushanda seyekutanga hydrocarbon-inotakura reservoirs munzvimbo dzakadzika dzemvura, inoratidzira yakaderera permeability maitiro. Iyi inherent petrophysical pfuma inobatanidza zvakanyanya kuoma kwehunyanzvi mukuona zvinogoneka mune zvekutengesa, hukuru-hukuru nhandare yemafuta.
Pasi rose, ingangoita 60% yezvichangobva kuwanikwa hydrocarbon reserves mumakore achangopfuura akatorwa kubva pakadzika mafomu. Kuenzaniswa nemadziva epakati-akadzika, maumbirwo akadzika-akadzika-akadzika anoratidza zvakanakira geological zvinosanganisira yakakwira tembiricha-kudzvanywa hurumende, yakakwirira hydrocarbon maturity, uye proximal hydrocarbon migration-accumulation systems. Aya mamiriro anonyanya kubatsira kugadzirwa kwegasi rechisikigo uye chiedza chisina kuchena mafuta.
Sezvineiwo, maumbirwo aya ane zviwanikwa zvisina kushandiswa zvine hunyanzvi hwekuongorora, zvichidziisa senzvimbo dzakakosha dzekutsiva kuchengetedza kukura kweramangwana uye kuwedzera kwekugadzirwa muindasitiri yepetroleum.
Offshore clastic rock reservoirs mune yakadzika-yakadzika-yakadzika maumbirwo anowanzo gadzira jecha uye silt panguva yekuchera mafuta / gasi, zvichiisa njodzi dzekupwanya, kuvhara, uye kukukurwa kwemiti yeKisimusi yepasi pegungwa, manifolds, mapaipi, pamwe nepamusoro pekugadzira michina. Yedu Yakanyanya anti-kukukurwa kweCeramic Hydrocyclone Desanding Systems yakashandiswa zvakanyanya mumafuta negasi minda kwemakore. Tine chivimbo chekuti, pamusoro pemhinduro dzedu dzepamberi dzekubvisa, iyo ichangobva kuwanikwa Huizhou 19-6 Oiri & Gasi Munda ichatorawo yedu Yepamusoro-inoshanda Hydrocyclone Oil Removal System, Compact Injet-Gas Flotation Unit (CFU) nezvimwe zvigadzirwa.
