Njengamanje, ukubuyiswa kwamafutha angasetshenziswa kabusha kusewumsebenzi onzima kakhulu, futhi imishini nobuchwepheshe bokubuyiselwa, ukucubungula kanye nokusetshenziswa kabusha kwegesi kaphethiloli encibilikisiwe endaweni yokukhiqiza nokugcina entantayo (i-FPSO) enesikhala esincane kanye namamojula agxile kakhulu ekukhiqizeni, ekucubunguleni nasezindaweni zokuhlala kuyinselele enzima nakakhulu.
Ukuphendula lokhu, i-CNOOC iqhubekile nokwenza ngcono futhi yaguqula imishini yobuchwepheshe ekhona eminyakeni yamuva nje, ekugcineni yenza ukuthi isibani esivuthayo ku-FPSO singasasebenzi, futhi iletha isilinganiso sesicelo kanye nezindlela zobuchwepheshe zokubuyisa izinsiza kanye nokusetshenziswa kabusha ezingeni elisha.
Ngokusho kukaChen Yimin, iphini lomphathi jikelele we-CNOOC Zhanjiang Branch, ngoNovemba 5, iyunithi yokubuyisa igesi kaphethiloli encibilikisiwe (LPG) yaseWenchang oilfield ye-CNOOC Zhanjiang Branch yasebenza ngokuphepha isigamu senyanga futhi yasebenza kahle, yafinyelela umphumela olindelekile wokukhiqizwa kwesilingo, ngokubuyiselwa okumaphakathi kwansuku zonke kwama-cubic metres angu-110 egesi kaphethiloli encibilikisiwe kanye nama-cubic metres angu-70 e-condensate. Ngemva kokukhiqizwa okuvamile kwephrojekthi yokubuyisa nokwakha kabusha i-LPG eWenchang oilfield, cishe ama-cubic metres angu-100000 egesi ehlobene namafutha angatholakala minyaka yonke. Le phrojekthi izodlala indima enhle ekuvikelweni kwemvelo yasolwandle.
Amasimu kawoyela aphesheya kwezilwandle anethuba elikhulu lokonga amandla
Iyunithi yokubuyisa nokuguqula i-LPG yegatsha le-CNOOC Zhanjiang ifinyelele umphumela olindelekile wokukhiqizwa kwesilingo, okungagcini nje ngokwandisa impilo yezomnotho yensimu kawoyela, kodwa futhi okubonisa ukuthi enkambisweni yokuthuthukiswa kwamabhizinisi ezinsizakusebenza esikhathini esizayo, ukubuyiselwa nokusetshenziswa kabusha kwezinsizakusebenza kuzokhushulwa kancane kancane kube sezingeni elifanayo noma elibaluleke kakhulu njengokukhiqiza nokuthuthukiswa kwamandla.
UChen Yimin uthe njengamanje, amasimu kawoyela asogwini anamandla amakhulu okonga amandla, ngoba ngesikhathi sokuxhashazwa kwensimu kawoyela, igesi ehambisana noketshezi lwe-petroleum izovela phakathi kwezingqimba zikawoyela. Ingxenye eyinhloko yi-methane, evame ukuqukethe inani elikhulu lezingxenye ze-ethane ne-hydrocarbon. Ukubuyiswa nokwelashwa kwegesi okuhlobene kubhekisela ekuhlukaniseni i-ethane, i-propane, i-butane kanye nezingxenye ezisindayo emseleni wegesi, ezingacutshungulwa futhi zithengiswe njengezingxenye ezimsulwa noma ingxube yegesi yemvelo (NGL) noma i-LPG. Ngakho-ke, igesi ehlobene ingeyemandla atholakalayo. Kodwa-ke, ngenxa yokuvinjelwa kwezindlela zobuchwepheshe kanye nokulawulwa okunzima kwegesi ehlobene enkambisweni yokuxhashazwa kwensimu kawoyela, ingxenye enkulu yegesi ehlobene iyakhishwa noma ishiswe.
Uphinde wanikeza isibonelo esicacile ukuze abonise inkinga: emzamweni we-South China Sea FPSO wegatsha le-CNOOC Zhanjiang elisebenza eWenchang oil field, ithoshi liyavutha unyaka wonke ukuze libhekane negesi ehlobene evela emasimini kawoyela asogwini. Ngemva kokubala, igesi ehlobene kanye ne-condensate eshiswa yithoshi emzamweni nsuku zonke kuzolingana neFerrari ngentengo yangaleso sikhathi. Ngakho-ke, kuyaphuthuma ukuthi igatsha le-CNOOC Zhanjiang lenze umsebenzi wokwakha kabusha nokusetshenziswa kwegesi ehlobene nehhashi, lithuthukise amandla okukhiqiza i-oyela field futhi likhuthaze ukuthuthukiswa komnotho osindisa amandla.
