I-CNOOC Imemezela Ukuqaliswa Kokukhiqiza Kuphrojekthi Yellowtail yase-Guyana

I-China National Offshore Oil Corporation Imemezela Ukuqala Kwangaphambi Kokukhiqiza Kuphrojekthi Yellowtail e-Guyana.

Iphrojekthi ye-Yellowtail ise-Stabroek Block offshore Guyana, enobunzulu bamanzi obusuka ku-1,600 kuya ku-2,100 wamamitha. Izakhiwo eziyinhloko zokukhiqiza zihlanganisa umkhumbi owodwa Wokukhiqiza Okuntantayo, Isitoreji, Nokulayishwa (FPSO) kanye nohlelo olulodwa lokukhiqiza olungaphansi kolwandle. Lo msebenzi uhlela ukuletha imithombo yokukhiqiza engama-26 kanye nemithombo yokujova amanzi engama-25 nge-inthanethi.

I-FPSO yale phrojekthi okwamanje inkulu e-Stabroek Block yase-Guyana, enamandla okugcina uwoyela aklanyelwe cishe imiphongolo eyizigidi ezimbili.

I-CNOOC Petroleum Guyana Limited, inkampani ephethwe ngokuphelele ye-CNOOC Limited, inzalo engama-25% ku-Stabroek Block. I-opharetha i-ExxonMobil Guyana Limited inamasheya angu-45%, kuyilapho i-Hess Guyana Exploration Ltd. inenzalo engu-30% esele.

I-Stabroek Block, etholakala emanzini ajule kakhulu (amamitha angu-1,600-2,000) ukusuka enyakatho-mpumalanga yeGuyana, iziqhayisa ngezinga elimangalisayo lempumelelo yokuhlola cishe nokutholakele okungu-40 kuze kube manje, ephethe isamba sezinsiza ezitholakalayo ezitholakalayo ezingaphezu kwezigidigidi eziyi-11 zemiphongolo kawoyela elingana.

Ngaphakathi kwebhlokhi, amaphrojekthi weLiza Phase 1, Liza Phase 2, kanye nePayara aseqalile ukukhiqiza. Ngokuphawulekayo, iphrojekthi ye-Payara izuze ukukhiqizwa okuphezulu phakathi nezinyanga ezintathu nje iqalile ngoNovemba 2023, ibeka irekhodi elisha lokuthuthukiswa kwendawo yamanzi ajulile.

Ukutholwa kuka-2024 kwenkambu ye-Bluefin yamathani ayizigidi eziyizinkulungwane kuye kwanweba futhi indawo yokugcina indawo eseningizimu-mpumalanga. “Ijika lesibili lokukhula” livulwa kanyekanye isu lokuthuthukisa igesi yemvelo - uhulumeni waseGuyanese uhlela ukuthutha igesi ehlobene ngamapayipi angaphansi kolwandle ukuya ogwini ukuze kwenziwe amaphrojekthi kagesi kanye ne-petrochemical, okwenza ukusebenzisana nobungcweti bezobuchwepheshe be-CNOOC's FLNG (Floating LNG).

Le ndlela enezingoma ezimbili “yesikali sokukhiqiza sikawoyela kanye negesi yokuthuthukisa inani” isungule ubambiswano lwase-Guyana njengesivikelo samasu se-CNOOC ngokumelene nezingozi zokushintsha kwamandla.

INingizimu Melika manje isivele njengesifunda esibalulekile sokulondolozwa nokukhiqizwa kwe-CNOOC phesheya. Lokhu kukhula kuveza amandla ezobuchwepheshe kanye nokusebenza kahle kakhulu:

Njengoba libhekene nezimo zamanzi ajulile adlula amamitha angu-1,600, ithimba le-CNOOC lihole izixazululo zokumba ezithuthukisiwe, lehlisa izindleko zaba ngu-20% womthombo owodwa ungaphansi kwesilinganiso semboni. Uhlelo olusha lukaphethiloli olukabili olufakwe kumiklamo ye-FPSO lwehlise umfutho wokuphuma kwe-carbon dioxide ngama-35%.

Okubaluleke nakakhulu, iphrojekthi yase-Guyana isiyi-incubator yokusebenza komhlaba wonke kwe-CNOOC, isungula imodeli ephindaphindekayo, ekhwehlelayo ukuze ithuthuke kahle futhi isebenze ezindaweni eziyinkimbinkimbi zamanzi ajulile. Le mpumelelo idala ipharadigm yokusebenza edluliselwe kumaphrojekthi wesikhathi esizayo emhlabeni jikelele.

Ukukhishwa kukawoyela negesi yemvelo akukwazi ukufezwa ngaphandle kwama-desanders.

I-cyclonic desanding separator iyisisetshenziswa sokuhlukanisa esiqinile segesi. Isebenzisa isimiso sesivunguvungu ukuze ihlukanise okuqinile, okuhlanganisa intlenga, imfucumfucu yamatshe, ama-chips ensimbi, isikali, namakristalu omkhiqizo, kusukela kugesi yemvelo ene-condensate & namanzi (uketshezi, amagesi, noma ingxube yoketshezi lwamagesi). Kuhlanganiswe nobuchwepheshe obukhethekile be-SJPEE obunelungelo lobunikazi, nochungechunge lwamamodeli we-liner (, into yokuhlunga), eyenziwe ngezinto zokwakha ze-ceramic ezingagugi (noma ezibizwa ngokuthi ezimelene nokuguguleka kakhulu) noma izinto ze-polymer ezingagugi noma izinto zensimbi. Ukuhlukaniswa kwezinhlayiyana eziqinile ezisebenza kahle kakhulu noma okokusebenza kwezigaba kungaklanywa futhi kwenziwe ngokwezimo zokusebenza ezihlukene, izinkambu ezahlukene kanye nezidingo zabasebenzisi. Ngokufakwa kweyunithi yesishingishane sokudiliza, ipayipi elingaphansi kolwandle elingaphansi komfula livikelekile ekugugulekeni nasezintweni eziqinile ezihlala phansi futhi zehlise kakhulu imvamisa yokusebenza kwezingulube.

Ama-cyclonic desanders ethu asebenza kahle kakhulu, anokusebenza kwawo okumangazayo okungu-98% kokuhlukanisa ama-microns angu-2 akhipha, kodwa aqine kakhulu unyawo (usayizi we-skid 1.5mx1.5m womkhumbi owodwa we-D600mm noma 24”NB x ~3000 t/t) ukuze ulashwe u-300~3000 t/t/t) ukuze ulashwe u-300~3000 t/t/t) okhiqizwe amanzi amaningi ngesimangalo samanzi esiphuma ku-300 ~ 400 M3 I-cyclone yethu esebenza kahle kakhulu i-desander isebenzisa izinto zobumba ezithuthukisiwe ezingagugi (noma ezibizwa ngokuthi, izinto ezilwa nokuguguleka), zifinyelela ukusebenza kahle kokususa isihlabathi okungafika kuma-microns angu-0.5 ngo-98% ukuze kuhlanzwe igesi. Ukuthuthukiswa kwamadamu futhi kuthuthukisa kakhulu ukutholakala kukawoyela noma, kungaphatha amanzi akhiqiziwe ngokususa izinhlayiya zama-microns angu-2 ngaphezulu ku-98% ukuze ziphinde zijovwe ezizindeni, kunciphise umthelela wendawo yasolwandle kuyilapho kuthuthukisa ukukhiqizwa kwenkundla kawoyela ngobuchwepheshe bokugcwala kwamanzi.

Inkampani yethu izimisele ngokuqhubekayo ekuthuthukiseni i-desander esebenza kahle, ehlangene, futhi engabizi kakhulu kuyilapho igxile ekusungulweni okunobungani kwemvelo. Ama-desander ethu afika ngezinhlobo eziningi ezahlukene futhi anezinhlelo zokusebenza eziningi, njengeI-Cyclone Desander esebenza kahle kakhulu, Wellhead Desander, I-Cyclonic Well isakaza i-Desander engahluziwe Nge-Ceramic Liners, Umjovo wamanzi Desander,NG/shale Igesi Desander, njll. Idizayini ngayinye ihlanganisa izinto zethu ezintsha zakamuva zokuletha ukusebenza okuphezulu kuzo zonke izinhlelo zokusebenza zezimboni ezihlukahlukene, kusukela emisebenzini evamile yokumba kuya ezidingweni zokucubungula ezikhethekile.

Ama-desander ethu akhiqizwa kusetshenziswa izinto zensimbi, izinto ze-ceramic ezingagugi, nezinto ezimelana ne-polymer ukumelana.

I-cyclone desander yalo mkhiqizo inekhono eliphezulu lokususa isihlabathi. Izinhlobo ezahlukene zamashubhu e-cyclone angasetshenziswa ukuhlukanisa noma ukususa izinhlayiya ezidingekayo kububanzi obuhlukene. Imishini incane ngosayizi futhi ayidingi amandla namakhemikhali. Inempilo yesevisi yeminyaka engaba ngu-20 futhi ingakhishwa ku-inthanethi. Asikho isidingo sokumisa ukukhiqizwa kokukhipha isihlabathi.

I-SJPEE inethimba lezobuchwepheshe elinolwazi elisebenzisa izinto ezithuthukisiwe ze-cyclone tube nobuchwepheshe bokuhlukanisa.

Ama-desanders e-SJPEE asetshenziswe kumapulatifomu e-wellhead nasezinkundleni zokukhiqiza ezindaweni zegesi namafutha njenge-CNOOC, i-PetroChina, i-Malaysia Petronas, i-Indonesia, i-Gulf of Thailand, nezinye. Asetshenziselwa ukususa izinto eziqinile kugesi noma emanzini oketshezi noma amanzi akhiqiziwe, kanye nokususwa kokuqina kwamanzi olwandle noma ukutholwa kokukhiqiza. Umjovo wamanzi kanye nezikhukhula zamanzi ukwandisa ukukhiqizwa nezinye izikhathi. Le nkundla yokuqala ibeke i-SJPEE njengomhlinzeki wesixazululo owaziwa emhlabeni wonke ekulawuleni okuqinile nobuchwepheshe bokuphatha. Sihlala sibeka phambili izintshisekelo zamakhasimende ethu futhi siphishekela ukuthuthukiswa okufanayo nawo.
