Ngomhla zingama-30 ku-Agasti, i-China National Offshore Oil Corporation (CNOOC) yamemezela ukuthi ukukhiqizwa kukawoyela osindayo osindayo phesheya kwezilwandle okuqoqekile kudlule amathani ayizigidi ezi-5. Lokhu kuphawula itshe elibalulekile ekusetshenzisweni okukhulu kwezinhlelo zobuchwepheshe bokuthola uwoyela osindayo osindayo ogwini kanye nemishini ebalulekile, okusungula iChina njengezwe lokuqala emhlabeni ukuthola ukuthuthukiswa okukhulu kokululama kowoyela osindayo ogwini lolwandle.
Ngokwemibiko, uwoyela omkhulu njengamanje uhlanganisa cishe u-70% wemithombo ye-petroleum esele emhlabeni, okwenza kugxilwe kakhulu ekukhuleni kokukhiqizwa emazweni akhiqiza uwoyela. Ngamafutha ane-viscosity esindayo, imboni ngokuyinhloko isebenzisa izindlela zokuvuselela ezishisayo ukuze zikhishwe. Umgomo oyinhloko uhilela ukujova izinga lokushisa eliphezulu, umusi onengcindezi ephezulu endaweni yokugcina uwoyela osindayo, ngaleyo ndlela unciphise i-viscosity yawo futhi uyiguqule ibe “amafutha alula” atholakala kalula.

Uwoyela osindayo uwuhlobo lwamafutha aluhlaza olubonakala nge-viscosity ephezulu, ukuminyana okuphezulu, uketshezi olubi, kanye nokuthambekela kokuqina, okwenza kube nzima kakhulu ukukhipha. Uma kuqhathaniswa nezindawo zikawoyela zasogwini, amapulatifomu angaphesheya anendawo elinganiselwe yokusebenza futhi angenisa izindleko eziphakeme kakhulu. Ngakho-ke, izinga elikhulu lokuthola kabusha kukawoyela osindayo kuletha izinselelo ezimbili mayelana nezinto zobuchwepheshe kanye nokusebenza komnotho. Lokhu kwamukelwa kabanzi njengenselelo enkulu yezobuchwepheshe nezomnotho embonini yezamandla emhlabeni wonke.
Imisebenzi yaseChina yokubuyisela uwoyela osindayo olwandle igxile kakhulu e-Bohai Bay. Kusungulwe izizinda eziningi zikawoyela zokululama okushisayo, okuhlanganisa iNanpu 35-2, Lvda 21-2, kanye namaphrojekthi we-Jinzhou 23-2. Ngo-2025, ukukhiqizwa kwaminyaka yonke okuvela ekululameni okushisayo kwase kudlule amathani ayizigidi eziyi-1.3, kanti okuphumayo unyaka wonke kulindeleke ukuthi kukhuphukele kumathani ayizigidi ezi-2.

Ukuze isebenzise kahle nangokwezomnotho izinqolobane zikawoyela osindayo, i-CNOOC iqhubekile nokwenza ucwaningo lwesayensi nokusungula izinto ezintsha zobuchwepheshe, iphayona “isibalo esiphansi somthombo, okukhiphayo okuphezulu” ithiyori yokuthuthukiswa kokululama okushisayo. Le nkampani yamukele imodeli yokuthuthukiswa kwephethini yomthombo wesikhala esikhulu ebonakala ngomjovo nokukhiqiza okuphezulu, ikhwalithi yesitimu esiphezulu, kanye nokuthuthukiswa kwe-synergistic ngokusebenzisa uketshezi olushisayo olunezingxenye eziningi.
Ngokujova isitimu esinekhalori ephezulu ehambisana namagesi ahlukahlukene kanye nama-ejenti amakhemikhali, futhi asekelwe ubuchwepheshe bokuphakamisa ivolumu ephezulu, le ndlela ithuthukisa kakhulu ukukhiqizwa komthombo ngamunye. Ibhekane ngempumelelo nezinselele ezithathe isikhathi eside ekutholeni uwoyela oshisayo, njengokukhiqiza okuphansi kanye nokulahlekelwa ukushisa okukhulu, ngaleyo ndlela kwenyusa izinga lokuthola kabusha kwawo wonke uwoyela osindayo.
Ngokwemibiko, ukuze kubhekwane nezimo eziyinkimbinkimbi zemigodi yokushisa ephezulu kanye nokucindezela okukhulu emisebenzini yokubuyisela uwoyela osindayo, i-CNOOC ithuthukise ngempumelelo imishini yokukhiqiza umjovo edidiyelwe ehamba phambili emhlabeni wonke ekwazi ukumelana no-350 degrees Celsius. Le nkampani isungule ngokuzimela amasistimu omjovo oshisayo ahlangene futhi asebenza kahle, amasistimu okulawula ukuphepha kwe-downhole, kanye namadivayisi okulawula isihlabathi isikhathi eside. Ngaphezu kwalokho, iklame futhi yakha inkundla yokuqala emhlabeni yomjovo we-thermal ephathwayo—“I-Thermal Recovery No.1″—igcwalisa igebe elibalulekile emandleni emishini yaseChina yokubuyisela uwoyela osindayo osindayo.
I-Thermal Recovery No.1″ Isetha Indawo Yokusebenza yase-Liaodong Bay
Ngokuthuthukiswa okuqhubekayo kohlelo lobuchwepheshe bokuthola kabusha okushisayo kanye nokuthunyelwa kwemishini ebalulekile, ukwakhiwa kwamandla okukhiqiza ukubuyisela uwoyela osindayo phesheya kwezilwandle kusheshiswe kakhulu, okuholele empumelelweni yokuthuthukiswa kwedamu. Ngo-2024, ukukhiqizwa kukawoyela osindayo phesheya kwezilwandle eChina kweqa uphawu lwethani eliyisigidi okokuqala ngqa. Kuze kube manje, ukukhiqizwa okwandayo sekudlule amathani ayizigidi ezinhlanu, okuzuzisa ukutholakala okukhulu kowoyela osindayo ezindaweni ezingasogwini lolwandle.
Uwoyela osindayo ubonakala ngokuminyana okuphezulu, i-viscosity ephezulu, nokuqukethwe okuphezulu kwe-resin-asphaltene, okuholela ekungangeni kahle kwamanzi. Ukukhishwa kwamafutha asindayo Kungathwala inani elikhulu lesihlabathi esiqinile esicolekile namafutha asindayo akhishiwe kanye nemiphumela yobunzima bokuhlukaniswa ohlelweni olungezansi lomfula, okuhlanganisa ukuhlanzwa kwamanzi akhiqiziwe noma izinga eliphansi lamanzi akhiqizwe ukuze alahlwe. Ngokusebenzisa umshini wokuhlukanisa isivunguvungu osebenza kahle kakhulu we-SJPEE, lezi zinhlayiya ezinhle zosayizi wehle ukuya kuma-serval microns zizosuswa ohlelweni lwenqubo oluyinhloko futhi zenze ukukhiqizwa kahle. .
Ngamalungelo obunikazi okuvikela ubunikazi bokusungula amaningi azimele, i-SJPEE iqinisekiswa ngaphansi kwe-DNV/GL-recognized ISO 9001, ISO 14001, kanye ne-ISO 45001 yokuphathwa kwekhwalithi nezinhlelo zesevisi yokukhiqiza. Sinikeza izixazululo zezinqubo ezithuthukisiwe, ukwakheka komkhiqizo okunembayo, ukubambelela ngokuqinile emidwebeni yedizayini ngesikhathi sokwakha, kanye nezinsizakalo zokubonisana nokusetshenziswa kwangemuva kokukhiqiza kumakhasimende kuzo zonke izimboni ezihlukahlukene.
Eyethuhigh-efficiency cyclone desanders, ngekhono layo elimangalisayo lokuhlukanisa elingu-98%, lithole ukutuswa okukhulu kuma-giants amaningi wamazwe ngamazwe. I-cyclone desander yethu esebenza kahle kakhulu isebenzisa izinto zokwakha ze-ceramic ezithuthukisiwe ezingagugi (noma ezibizwa ngokuthi, ezilwa nokuguguleka), ifinyelela ukusebenza kahle kokukhipha isihlabathi okungafika kuma-microns angu-0.5 ku-98% wokwelashwa kwegesi. Lokhu kuvumela igesi ekhiqiziwe ukuthi ifakwe ezinqolobaneni ukuze kutholakale indawo kawoyela ekwazi ukungena kancane esebenzisa izikhukhula zegesi exubene futhi ixazulule inkinga yokuthuthukiswa kwamadamu angakwazi ukungena kalula futhi ithuthukise kakhulu ukutholakala kukawoyela. Noma, ingakwazi ukwelapha amanzi akhiqiziwe ngokukhipha izinhlayiya zama-microns angu-2 ngaphezulu ku-98% ukuze iphinde ifakwe ngokuqondile kuma-reservoir, inciphise umthelela wemvelo yasolwandle kuyilapho ithuthukisa ukukhiqizwa kwendawo kawoyela ngobuchwepheshe bokugcwala kwamanzi.
I-hydrocyclone ye-SJPEE ye-desanding itshalwe ezinkundleni zokuxhumana nasezinkundleni zokukhiqiza kuzo zonke izizinda zikawoyela negesi ezisetshenziswa yi-CNOOC, CNPC, Petronas, kanye nase-Indonesia naseGulf of Thailand. Asetshenziselwa ukususa izinto eziqinile kugesi, uketshezi lwemithombo, noma i-condensate, futhi zisetshenziswa ezimeni ezifana nokususwa okuqinile kwamanzi olwandle, ukutholwa kokukhiqiza, umjovo wamanzi, kanye nezikhukhula zamanzi ukuze kuthuthukiswe ukutholakala kukawoyela.
Yiqiniso, i-SJPEE inikeza okungaphezu nje kwama-desanders. Imikhiqizo yethu, njengeukuhlukaniswa kwe-membrane - ukufeza ukususwa kwe-CO₂ kugesi yemvelo, ukuhlanza i-hydrocyclone, iyunithi yekhwalithi ephezulu ye-compact flotation (CFU), futhii-multi-chamber hydrocyclone, zonke zithandwa kakhulu.
