Inkambu yokuqala yegesi yaseChina eyizigidi eziyikhulu zamacubic meter eBohai Sea — Umsebenzi wokuthuthukiswa kwesigaba sokuqala usuphelele

Inkampani ye-CNOOC yaseTianjin imemezele ukuthi umklamo wokuthuthukiswa wesigaba sokuqala wensimu yegesi yaseBozhong 19-6, okuyinsimu yokuqala yegesi yemvelo eyizigidi eziyikhulu zamamitha ayisikwele eBohai Sea yaseChina, usuqediwe ngokugcwele. Umklamo njengamanje ukhiqiza amathani angaphezu kuka-5,200 kawoyela ngosuku, futhi ukusebenza kwawo kudlule lokho obekulindelekile.

Insimu yegesi yaseBozhong 19-6 itholakala emanzini aphakathi nendawo eBohai Sea. Inezinhlobo zokwakheka komhlaba eziqinisekisiwe ezingaphezu kwezigidi eziyikhulu zamamitha ayisikwele ezigesi yemvelo kanye nezigidi ezingaphezu kwezimbili zamamitha ayisikwele zoketshezi lwe-petroleum olutholakala endaweni. Indawo yokugcina igesi ilele ekujuleni okungaphezu kwamamitha angu-5,000, nokusabalalisa kwezinto ezingaphansi komhlaba kubanzi kodwa kuyinkimbinkimbi, kanye nezintaba ezigqinsiwe ezinemingcele eminingi.

Ngokusho komeleli we-Engineering Technology Operations Centre ye-CNOOC Tianjin Company, amaqembu ezobuchwepheshe abhekane namazinga okushisa okwakha afinyelela ku-204°C kanye nobulukhuni bedwala obudlula obensimbi evamile yekhabhoni. Ngenxa yalokho, ngokulandelana bagqashula ubuchwepheshe obuyisisekelo obune, okuhlanganisa amasu okumba imigodi ezindaweni eziqine kakhulu kanye nezinhlelo zoketshezi lokumba olumelana nokushisa okuphezulu, futhi bakha uhlelo lobuchwepheshe oluzimele nolulawulekayo oluhambisana nemithombo ejulile kakhulu yase-Bohai Sea. Baphinde baphumelela ukwenza umsebenzi wokuqala emhlabeni wonke wegatsha lomthombo endaweni ye-Archean buried hill formation. Esigabeni sokuqala, kwambiwa imithombo ejulile kakhulu eyi-10 engaphezu kwamamitha angu-6,000, okubeka irekhodi lenani lemithombo ejulile kakhulu ophrojethini owodwa wokuthuthukiswa kwe-Bohai oilfield, ngejubane lokujula kwemithombo elinganiselwa ngaphezu kwamamitha angu-5,500.

Ngaphakathi kwe-buried hill reservoir, igesi ye-condensate isakazwa kakhulu emifantwini ye-micron scale emincane njengenwele yomuntu. Ukukhiqiza ngendlela evamile ye-depletion drive kuba nokutholakala okuphansi, okwenza kube inselele ukuguqula izinqolobane zibe umkhiqizo ngempumelelo. Ithimba lobuchwepheshe laqhubeka libhekana nalezi zinselele, ekugcineni lathuthukisa uhlelo lobuchwepheshe bokuthuthukisa ama-hydrocarbon reservoirs ayinkimbinkimbi futhi ajulile kakhulu ezindaweni zasolwandle, futhi ngobuchule laphakamisa indlela yokuthuthukisa ngokujova igesi ngomjikelezo—ukubuyisela ingxenye yegesi ekhiqiziwe emhlabathini ukuze kugcinwe umfutho—okuxazulule ngempumelelo izinselele zokuthuthukisa.

Kuyaphawuleka ukuthi izinqolobane zegesi yemvelo zaseChina zitholakala kakhulu entshonalanga, kanti empumalanga zincane kakhulu. Njengendawo enkulu kunazo zonke yegesi yasolwandle empumalanga yeChina, iBozhong 19 6 isivele ikhiqize ngaphezu kwezigidi eziyizinkulungwane ezingu-2.8 zamamitha ayisikwele egesi yemvelo, okwenza ibe yinsika ebalulekile yokuqinisekisa ukuthi ukunikezwa kwegesi yemvelo endaweni yaseBeijing Tianjin Hebei kanye nendawo ezungezile yaseBohai kuzinzile.

Ukukhipha uwoyela negesi yemvelo akunakwenzeka ngaphandle kwemishini yokuhlukanisa.

I-SHANGHAI SAGA Offshore Engineering Co., Ltd., eyasungulwa e-Shanghai ngo-2016, iyinkampani yesimanje yezobuchwepheshe ehlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nesevisi. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yezimboni zikawoyela, igesi, namakhemikhali. Uhlu lwethu lwemikhiqizo enempumelelo ephezulu luhlanganisa ama-hydrocyclone okukhipha uwoyela/okukhipha amanzi, ama-desander ezinhlayiyeni ezingamamikhroni, namayunithi e-compact flotation. Sihlinzeka ngezixazululo eziphelele ze-skid-mounted futhi sinikeza nezinsiza zokulungisa imishini yezinkampani zangaphandle kanye nesevisi yangemva kokuthengisa. Siphethe amalungelo obunikazi amaningi futhi sisebenza ngaphansi kohlelo lokuphatha olugunyazwe yi-DNV-GL lwe-ISO-9001, ISO-14001, ne-ISO-45001, siletha izixazululo ezingcono kakhulu zenqubo, ukuklama okunembile komkhiqizo, ukuhambisana ngokuqinile nezimfuneko zobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.

I-i-cyclone desanders esebenza kahle kakhulu, adume ukuthi zihlukanisa amazinga angu-98%, zithole ukuqashelwa ngabaholi bamandla bamazwe ngamazwe. Zakhiwe ngobuciko obuthuthukile bokumelana nokugqokwa kwe-ceramic, lezi zingxenye zikhipha izinhlayiya ezicolekile ezingu-0.5 microns emoyeni ngezinga elingu-98%. Lokhu kusebenza kuvumela ukuthi igesi ekhiqiziwe iphinde ifakwe ukuze kube nokuxubana okuhle ezindaweni ezinokungena okuncane, okuyisixazululo esibalulekile sokuthuthukisa ukukhiqizwa kukawoyela ezindaweni eziyinselele. Ngokunye, zingalapha amanzi akhiqiziwe, zikhiphe izinhlayiya ezinkulu kuno-2 microns ngezinga elingu-98% ukuze ziphinde zifakwe ngqo, ngaleyo ndlela kuthuthukiswe ukusebenza kokunisela kwamanzi kuyilapho kuncishiswa umthelela emvelweni.

Umkhiqizo wethu omusha—I-Desander Yezinhlayiya Ezinhle Kakhulu Esebenza Ngamandla Aphezulu iyithuluzi lokuhlukanisa uketshezi nokuqinile elisebenzisa umgomo we-centrifugal osebenzayo ukuhlukanisa izinto ezihlanzekile ezimisiwe—njengezinto eziqinile emanzini akhiqiziwe, amanzi olwandle, i-condensate, izinhlayiya ezincane eketshezini olunamandla aphezulu, nempuphu ye-catalyst kuma-reactor—kuketshezi (uketshezi, amagesi, noma izingxube zoketshezi negesi). Likhipha ngempumelelo izinhlayiya eziqinile ezingafika ku-2 microns (ngokusebenza okungu-98%) noma ezincane kakhulu.

I-Desander Yezinhlayiya Ezinhle Kakhulu Esebenza Ngamandla AphezuluIletha ukusebenza okuphezulu kokususa isihlabathi, ekwazi ukususa izinhlayiya eziqinile kuze kufike kuma-micron angu-2. Umshini unendawo encane, awudingi amandla angaphandle noma izithasiselo zamakhemikhali, futhi unempilo yokusebenza ecishe ibe yiminyaka engu-20. Unikeza amandla okukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokumisa ukukhiqiza.

Kufakazelwe emikhakheni emikhulu yomhlaba wonke eqhutshwa yi-CNOOC, i-CNPC, i-Petronas, nabanye eNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa ezinkundleni zomthombo kanye nezinkundla zokukhiqiza. Ahlinzeka ngokususwa okuqinisekile kwezinto eziqinile kugesi, uketshezi lomthombo, kanye ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ukuvikelwa kokugeleza kokukhiqiza, kanye nezinhlelo zokujova amanzi / zokugcwaliswa kwamanzi.

Ngaphandle kwama-desander, i-SAGA inikeza iphothifoliyo yobuchwepheshe bokuhlukanisa obuhlonishwayo. Umugqa wethu womkhiqizo ufakaizinhlelo ze-membrane zokususa i-CO₂ kugesi wemvelo, ama-hydrocyclone okukhipha uwoyela, amayunithi amancane okuntanta (CFUs) asebenza kahle kakhulu, Ukuhlukaniswa kwesihlabathi segesi ye-shale, Iphakethe lokukhipha amanzi nge-cyclonic elihlanganisa nokwelashwa kwamanzi akhiqiziwe, futhi ama-hydrocyclone anamagumbi amaningi, okunikeza izixazululo eziphelele ezinseleleni ezinzima zomkhakha.
