Ukukhiqizwa okuhlanganisiwe enkundleni kaphethiloli osindayo ongaphansi kakhulu emhlabeni kudlule amathani ayizigidi ezingu-10.

NgoJuni 29, kwatholakala ku-CNPC ukuthi ukukhiqizwa kukaphethiloli okuhlanganisiwe e-Lukqun Oilfield – indawo yokuqala emhlabeni enezinga eliphansi kakhulu lokukhiqiza uwoyela osindayo ongajwayelekile, etholakala ngasezansi kwezintaba ezivutha umlilo e-Turpan, e-Xinjiang – kudlule amathani ayizigidi ezingu-10.

Uwoyela osindayo ongajwayelekile ubhekisa ezinsizeni zikaphethiloli ezimbiweyo amakhilomitha ambalwa ngaphansi komhlaba, anokujiya okuphindwe izikhathi ezimbalwa kunokwejwayelekile kukaphethiloli ojwayelekile, futhi cishe awukwazi ukuhamba njengodaka olumnyama ezingeni lokushisa lokujwayelekile, okwenza kube nzima kakhulu ukuwukhipha.

Izindawo zamafutha anzima zeLukqun Oilfield, ezitholakala ngaphakathi kweTurpan Basin nasemathafeni aseNingizimu eziNtabeni Ezivuthayo, ngokuvamile zingcwatshwe emagqumeni angaphezu kwamamitha angu-2,300, kanti ezijulile zifinyelela ku-5,200 metres. Le ndawo ayiyona kuphela indawo ephansi kakhulu emhlabeni yokuthuthukisa uwoyela onzima kakhulu, kodwa futhi iyindawo enkulu yamafutha anzima esiqalisiwe ukuthuthukiswa kwezentengiselwano eChina.

UNgqongqoshe uWang Sheng, ovela eMnyangweni Wocwaningo Lwezindawo Zamafutha zeLukqun Production Management Area, iTuha Oilfield, iCNPC, uthe: "Uwoyela lapha unezinga eliphezulu, ubukhulu obuphezulu, kanye nezinga eliphezulu lokubanda, okwenza kube inselele eyaziwa umhlaba wonke kwezentuthuko zamafutha negesi."

Ngenxa yokuthi uwoyela osindayo emkhakheni kawoyela iLukqun ungcwatshwe ujule kakhulu, ukulahleka okukhulu kokushisa kwenzeka ngesikhathi sokuhanjiswa komgodi womgodi okude, okwenza izindlela zokubuyisa ezijwayelekile zokushisa zingasebenzi nhlobo. Esigabeni sokuqala sokuthuthukiswa, umkhakha kawoyela ubhekene nenkinga "yokungabi nolwazi oluvuthiwe ongasebenzisa kulo futhi kungabikho ubuchwepheshe obusekelayo ongabuthola."

Zou Chenglin, umphathi we-Lukqun Production Management Area yeTuha Oilfield, i-CNPC, uthe: "Ngokungeza uwoyela olukhanyayo emgodini womthombo ngendlela entsha, senze uwoyela osindayo – obekuvame ukuthi 'ubunzima ukuhamba futhi ungaphumpelwa' – ukuthi uphumele phezulu kalula usuka emagunjini ajule kangangezinkulungwane ezintathu zamamitha. Izinga lokubuyiselwa kukaphethiloli liye landa ngamaphesenti angu-11 uma liqhathaniswa nesigaba sokuqala sokuthuthukiswa, sifinyelela ukukhiqizwa okukhulu nokonga izindleko kwemithombo okwakunzima ukuyithola."

Ngenxa yalezi zimpumelelo zobuchwepheshe, umkhiqizo waminyaka yonke we-Lukqun Oilfield wenyuka usuka ku-30,000 wamathani wafinyelela esiqongweni sika-800,000 wamathani, futhi ugcine ukukhiqiza okuzinzile okungaphezu kuka-400,000 wamathani iminyaka eyi-10 ilandelana.

Ukukhiqizwa kukayeleni negesi yemvelo akunakwenzeka ngaphandle kwemishini yokuhlukanisa.

I-Shanghai SAGA Offshore Engineering Co., Ltd., eyasungulwa e-Shanghai ngo-2016, iyibhizinisi lobuchwepheshe lesimanje elihlanganisa i-R&D, ukuklama, ukukhiqiza, kanye nenkonzo. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yemboni kawoyela, igesi, kanye ne-petrochemical. Uhlu lwethu lwemikhiqizo esebenza kahle kakhulu luhlanganisa ama-hydrocyclone okukhipha uwoyela/amanzi, ama-desander ezinhlayiya ezincane kakhulu, namayunithi okuhlanganisa aqinile. Sinikeza izixazululo eziphelele ezifakwe ezindaweni ezi-skid futhi sinikeza nokulungiswa kabusha kwemishini yenkampani yangaphandle kanye nezinsizakalo zangemuva kokuthengisa. Sibambe izimvume eziningi zobunikazi futhi sisebenza ngaphansi kwesistimu yokuphatha eqinisekiswe yi-DNV-GL ISO-9001, ISO-14001, kanye ne-ISO-45001, siletha izixazululo zenqubo ezithuthukisiwe, ukuklama komkhiqizo okunembayo, ukugcinwa ngokuqinile kwezicaciso zobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.

Yethu ama-desander we-cyclone aphumelela kakhulu, ezaziwa ngesilinganiso sazo esihle kakhulu sokuhlukanisa esingu-98%, zithole ukubuyekezwa okuvela kubaholi bamandla aphesheya kwezilwandle. Zakhiwe ngobuchwepheshe obusezingeni eliphezulu be-ceramics ekwazi ukumelana nokuguga, lezi zinhlelo zikwazi ukususa 98% wezinhlayiya ezincane njengama-0.5 microns emifudlaneni yegesi. Leli khono lenza ukuthi igesi ekhiqiziwe ingene kabusha ukuze isetshenziswe ekugcwaliseni okuxubile emifuleni enomoya ophansi, isixazululo esibalulekile sokuthuthukisa ukubuyiselwa kukaphethiloli ezindaweni eziyinselele. Kungenjalo, zingakwazi ukwelapha amanzi akhiqiziwe, zikhiphe 98% wezinhlayiya ezinkulu kune-2 microns ukuze zingene kabusha ngqo, ngaleyo ndlela zithuthukise ukusebenza kahle kokugeleza kwamanzi ngenkathi kuncishiswa umthelela emvelweni.

Umkhiqizo wethu omusha—I-High Efficiency Ultra-Fine Particle Desander iyidivayisi yokuhlukanisa uketshezi-okuqinile esebenzisa isimiso esisebenza kahle se-centrifugal ukuhlukanisa izinto ezingcolile ezintantayo—njengezinto eziqinile emanzini akhiqiziwe, emanzini olwandle, ekuhlanganeni, izinhlayiya ezinhle emanzini anokujiya okuphezulu, kanye nomgqomo wokukhipha izinto ezithile kumareyaktha—kusuka eketshezini (uketshezi, amagesi, noma ukuxubana kwamagesi-uketshezi). Iyakwazi ukususa izinhlayiya eziqinile ezinosayizi abangafika ku-2 microns (ngokuphumelela okungu-98%) noma ngaphansi.

I-High Efficiency Ultra-Fine Particle Desanderiletha ukusebenza kahle kakhulu ekususeni isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifika ku-2 microns. Le mishini inendawo encane, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inomsebenzi weminyaka engaba ngu-20. Inikeza amandla okukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokuyeka ukukhiqiza.

Kufakazelwe emikhakheni emikhulu yomhlaba ephethwe yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-SAGA desanders afakwa ezindaweni zokubhola kanye nezinkundla zokukhiqiza. Ahlinzeka ngokususwa okuthembekile okuqinile okuvela egazini, uketshezi lokukhiqiza, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa komjikelezo wokukhiqiza, kanye nezinhlelo zokujova/ukugcwalisa amanzi.

Ngaphandle kwama-desanders, i-SAGA inikeza iqoqo lobuchwepheshe bokuhlukanisa obunconywayo. Umugqa womkhiqizo wethu uhlanganisa, izinhlelo zamalungu okususa i-CO₂ egazini lemvelo, ama-hydrocyclone okukhipha uwoyela, amayunithi acindezelayo aphezulu (CFUs), ukususwa kwesihlabathi segesi ye-shale, Iphakethe lokukhipha amanzi nge-cyclone elokwelapha amanzi akhiqiziwe, futhi ama-hydrocyclone anezigaba eziningi, ahlinzeka ngezixazululo eziphelele zezinselelo ezinzima kakhulu zemboni.
