Ngomhla wama-31 kuMatshi, i-CNOOC ibhengeze ukufunyanwa kweTshayina kwindawo yeoli ye-Huizhou 19-6 enogcino oludlula iitoni ezizigidi ezili-100 kwimpuma yoLwandle lwaseTshayina. Oku kuphawula indawo yeoli yokuqala edibeneyo yaseTshayina ekude nonxweme kulwakhiwo lwamatye anzulu, abonisa ukubanako ukuphononongwa kwiindawo zogcino zehydrocarbon ezinzulu zelizwe.
Ifakwe kwi-Huizhou Sag ye-Pearl River Mouth Basin, malunga neekhilomitha ezili-170 kude nonxweme ukusuka e-Shenzhen, indawo yeoli ye-Huizhou 19-6 ihlala kumndilili wamanzi oziimitha ezili-100. Iimvavanyo zemveliso zibonise imveliso yemihla ngemihla ye-413 imiphanda yeoli ekrwada kunye ne-68,000 cubic metres yegesi yendalo kwiqula ngalinye. Ngeenzame zokuphonononga ezizinzileyo, ibala lizuze isiqinisekiso sogcino lwejoloji ngaphezu kwe-100 lezigidi zeetoni ezilingana ne-oyile.
Iqonga lokomba elithi "Nanhai II" liqhuba imisebenzi yokomba kwindawo yeoli yaseHuizhou 19-6.
Kuphononongo lwe-oyile nerhasi elunxwemeni, imizobo enobunzulu bokungcwaba obungaphezulu kwe-3,500 yeemitha ihlelwa ngokobuchwephesha njengamadama anzulu, ngelixa lawo angaphaya kwama-4,500 eemitha ahlelwa njengamadama anzulu kakhulu. Ukuphononongwa kwezi ndawo zaselwandle ezinzulu kakhulu kuzisa imingeni eyoyikekayo yobunjineli, kubandakanywa iimeko zobushushu obugqithisileyo/noxinzelelo oluphezulu (HT/HP) kunye neemeko ezintsonkothileyo zolwelo.
Ukwakheka kwamatye akudala, ngelixa esebenza njengemithombo ephambili ye-hydrocarbon-ethwele kwisetingi zamanzi anzulu, zibonisa iimpawu ezisezantsi zokungena. Le propathi yendalo ye-petrophysical idibanisa kakhulu ubunzima bobugcisa ekuchongeni uphuhliso olunorhwebo, uphuhliso olukhulu lwendawo yeoli.
Ehlabathini jikelele, malunga ne-60% yogcino lwe-hydrocarbon esanda kufunyanwa kwiminyaka yakutshanje ifunyenwe kulwakhiwo olunzulu. Xa kuthelekiswa namadama aphakathi angekho nzulu, ubunzulu obunzulu kakhulu bubonisa iingenelo ezikhethekileyo zejoloji kuquka ulawulo loxinzelelo oluphezulu lobushushu, ukuvuthwa okuphezulu kwehydrocarbon, kunye neenkqubo ezisondeleleneyo zokufuduka kwehydrocarbon. Ezi meko zinceda ngakumbi ukuveliswa kwegesi yendalo kunye ne-oyile ekrwada ekhanyayo.
Ngokucacileyo, olu qulunqo luqulathe izibonelelo ezininzi ezingasetyenziswanga nezinokukhula okuphantsi kophononongo, zizibeka njengeendawo ezifuna ukutshintshwa ngobuchule ukuze kugcinwe ukukhula koovimba bexesha elizayo kunye nokwandiswa kwemveliso kushishino lwepetroleum.
Amadama amatye angaphantsi kolwandle akwindlela enzulu kakhulu-nzulu athanda ukuvelisa isanti kunye nentlenga ngexesha lokutsalwa kwe-oyile/irhasi, nto leyo ebeka imingcipheko yokurhawuka, ukuvaleka, kunye nokukhukuliseka kwimithi yeKrisimesi engaphantsi kolwandle, iindawo ezininzi, imibhobho, kunye nezixhobo zokusebenza ezingaphezulu. IiNkqubo zethu zokuNxilwa ngokuPhakamileyo kweCeramic Hydrocyclone Desanding zisetyenziswe ngokubanzi kumasimi e-oyile nerhasi iminyaka. Siqinisekile ukuba, ukongeza kwizisombululo zethu eziphambili zokulahla, i-Huizhou 19-6 ye-Oli kunye ne-Gas Field esanda kufunyanwa iya kwamkela iNkqubo yethu yokuSuswa kweOyile yeHydrocyclone eSebenza ngokuPhezulu, iYunithi ye-Compact Injet-Gas Flotation (CFU) kunye nezinye iimveliso.
