NgoMashi 31, i-CNOOC yamemezela ukutholwa kweChina indawo kawoyela i-Huizhou 19-6 enezindawo ezigciniwe ezingaphezu kwamathani ayizigidi eziyi-100 empumalanga yeSouth China Sea. Lokhu kuphawula indawo yokuqala kawoyela yaseShayina edidiyelwe engasogwini ekwakhiweni kwamatshe acwebezelayo ajule kakhulu, okubonisa amandla abalulekile okuhlola ezindaweni ezisogwini ezingasogwini ze-hydrocarbon ezijulile.
Itholakala e-Huizhou Sag ye-Pearl River Mouth Basin, cishe amakhilomitha angu-170 ukusuka ogwini ukusuka e-Shenzhen, isizinda sikawoyela sase-Huizhou 19-6 sihlala emanzini ajulile angamamitha ayi-100. Ukuhlolwa kokukhiqiza kubonise ukuphuma kwansuku zonke kwemiphongolo kawoyela ongahluziwe engu-413 kanye ne-cubic metres engu-68,000 yegesi yemvelo emthonjeni ngamunye. Ngemizamo eqhubekayo yokuhlola, lo mkhakha uzuze izinqolobane zokwakheka komhlaba eziqinisekisiwe ezingaphezu kwamathani ayizigidi eziyi-100 okulingana nowoyela.
Indawo yokumba i-"Nanhai II" yenza imisebenzi yokumba emanzini ase-Huizhou 19-6 oilfield
Ekuhloleni uwoyela negesi phesheya kwezilwandle, amafomu anobunzulu bokungcwaba obudlula amamitha angu-3,500 ahlukaniswa ngokobuchwepheshe njengamadamu ajulile, kuyilapho lawo angaphezu kwamamitha angu-4,500 ahlukaniswa njengamadamu ajule kakhulu. Ukuhlola kulezi zindawo zasolwandle ezijule kakhulu kuveza izinselele ezinkulu zobunjiniyela, okuhlanganisa nezimo zezinga lokushisa eliphezulu/ukucindezela okukhulu (HT/HP) kanye namandla oketshezi ayinkimbinkimbi.
Ukwakheka kwamadwala akudala, kuyilapho esebenza njengamadamu athwala i-hydrocarbon eyinhloko ezindaweni ezijulile zamanzi, abonisa izici zokungakwazi ukungena kalula. Lesi sakhiwo semvelo se-petrophysical sihlanganisa ngokuphawulekayo ubunzima bobuchwepheshe ekuhlonzeni ukuthuthukiswa kwendawo kawoyela esebenza ngokwentengiso, nezinga elikhulu.
Emhlabeni jikelele, cishe amaphesenti angama-60 ezindawo zokugcina i-hydrocarbon ezisanda kutholwa eminyakeni yamuva zithathwe ekwakhekeni okujulile. Uma kuqhathaniswa namadamu aphakathi nendawo angashoni, ukwakheka okujulile-okujule kakhulu kubonisa izinzuzo ezihlukile zejoloji ezihlanganisa izindawo eziphakeme zokucindezela kwezinga lokushisa, ukuvuthwa okuphezulu kwe-hydrocarbon, kanye nezinhlelo zokunqwabelana ze-hydrocarbon eziseduze. Lezi zimo zivumela ikakhulukazi ukukhiqizwa kwegesi yemvelo kanye nowoyela ongahluziwe omncane.
Ngokuphawulekayo, lezi zakhiwo ziqukethe izinsiza eziningi ezingakasetshenziswa ezinokuvuthwa okuncane uma kuqhathaniswa, okuzibeka njengezindawo ezibaluleke kakhulu zokushintshwa ukuze kuqhutshekwe nokukhula kwesabelomali esizayo kanye nokuthuthukiswa kokukhiqizwa embonini ye-petroleum.
Amachibi amadwala asogwini asezindaweni ezijulile kakhulu avame ukukhiqiza isihlabathi kanye nodaka ngesikhathi sokukhishwa kukawoyela/igesi, okubeka engcupheni yokuhuzuka, ukuvala nokuguguleka ezihlahleni zikaKhisimusi ezingaphansi kolwandle, izinhlobonhlobo, amapayipi, kanye nemishini yokucubungula engaphezulu. I-Highly anti-rosion Ceramic Hydrocyclone Desanding Systems yethu isetshenziswe kabanzi ezindaweni zikawoyela negesi iminyaka. Siyaqiniseka ngokuthi, ngaphezu kwezixazululo zethu ezithuthukisiwe zokususa udaka, i-Huizhou 19-6 Oil & Gas Field esanda kutholwa izosebenzisa Uhlelo lwethu Olusebenza Kakhulu Lokususa Uwoyela weHydrocyclone, I-Compact Injet-Gas Flotation Unit (CFU) neminye imikhiqizo.
