Irekhodi Lokuqhekeka Kwamafutha E-Bohai Liphinde Laqhekeka Kabusha
Muva nje, kubikwe kusuka eBohai Oilfield ukuthi i-Well A32 e-Bozhong 34-9 oilfield yenze ubuchwepheshe bokuhlukanisa kabusha imigodi ekhona okokuqala ngqa, yafinyelela ukukhuphuka okukhulu kokukhiqizwa kukayenga.
Lo msebenzi wokuhlukanisa owenziwe nge-single-well, single-layer usungule irekhodi elisha lokuhlukanisa eBohai Oilfield.
Njengoba iyindawo yokuqala yamafutha esihlabathini yasolwandle yaseChina ethonywe yiminyango yomlilo, i-Bozhong 34-9 oilfield inezendlalelo ezinamafutha ezifana "nethayela lezinyosi". Lokhu kubangela izakhiwo ezimbi zesitoreji, ukuxhumana okuyinkimbinkimbi, nokujova kwamanzi okungasebenzi ezindaweni ezingaphandle zeminyango yomlilo. Le ndawo yamafutha idinga ngempela ukukhuthazwa ngokuqhekeka ukuze kufezeke ukuthuthukiswa kokukhiqiza okusebenzayo ezindaweni ezinjalo.
Uhlakaniphile Lweqembu, Izixazululo Ezabiwe:
Ukubambisana Kolwandle-Nolwandle Okubhekana Nezinselele Eziyinkimbinkimbi
Ngokusekelwe emiphumeleni yocwaningo eshiwo ngenhla, ubuchwepheshe bokuqhekeka besikhashana obuhlanganisiwe bezigaba eziningi buasetshenziswe ku-Well A32 ye-Bozhong 34-9 oilfield. Kodwa-ke, kwavela izinselele ngesikhathi sokusebenza kokuqhekeka kwesigaba sokuqala, njengoba ingcindezi yokusebenza ingakhuphukanga njengoba bekulindelekile, okwaholela ekuhlulekeni kokufeza ukuxhumana okusebenzayo phakathi kwezindawo eziningi ezakhiwe ngokuvundlile.
Ukuqinisekisa ukuphumelela kokusebenza kokuhlukanisa, i-Bohai Oil Research Institute of Tianjin Branch, i-Bonan Operations Company, kanye ne-Engineering Technology Operations Center basebenze ngokubambisana eduze. Ngokubambisana komhlaba-ulwandle, benze ukuhlaziywa nezingxoxo, ekugcineni banqume isixazululo sokusebenza okulandelayo: ukwelula isikhathi sokwehla kwengcindezi ngendlela efanele nokwandisa umthamo we-ejenti yokuvimbela yesikhashana.
Abasebenzi bezobuchwepheshe esizeni ngokushesha benza izibalo zokulinganisa ukuze baqhathanise ngokuhlelekile izimo zokuqhekeka ngaphansi kwezikhathi ezahlukene zokwehla kwengcindezi kanye nokusebenza kokuvimbela ngemithamo ehlukahlukene yama-ejenti okuvimbela okwesikhashana. Ngale nqubo, amapharamitha okusebenza aphelele atholwa kancane kancane, aqinisekisa ukuqhubeka kahle kwemisebenzi yasensimini. Ngaleso sikhathi, kusekelwa ukuqapha okweqhwa kwezimbobo zesikhathi sangempela nokulungiswa kwamapharamitha ashukumisayo, izinga lokuvuselelwa kwesihlahla esiqondile likhuphuke laba ngaphezu kuka-90%, ivolumu yesihlahla evuselelwe yafinyelela kathathu kunezinga lezindlela ezijwayelekile, kwathuthukiswa kakhulu ukusebenza kahle kokusetshenziswa kwesihlahla.
Ukukhuthaza Ukukhiqiza:
Ukuphumelela Kokuphinda Ukuhlukanisa
UPhendula izinselelo ezifana ne-engeli ephakeme yokuhlehlisa yomthombo, izendlalelo eziningi zokuqhekeka, ukungasebenzi kahle kwezendlalelo ezilandelanayo zokuqhekeka, kanye nengozi enkulu yokubambeka kukagesi wokubhola ekusebenzeni okujwayelekile kwezendlalelo eziningi zokuqhekeka ngaphakathi nohambo olulodwa, uMnyango Wokukhiqiza Uwoyela we-COSL wamukele futhi waphumelela ukusebenzisa ubuchwepheshe bokudonsa isihlabathi obuthi "izigaba ezine kuhambo olulodwa". Lesi sinqumo sasekelwe ekulinganisweni okuningiliziwe kokugcwalisa isihlabathi kanye nokuhlaziywa okusebenzayo.
Lobu buchwepheshe abuvumeli nje kuphela ukuqhekeka kwezendlalelo eziningi ngokunembayo kodwa futhi buvimbela ukuhlala kwesihlabathi ngaphezu kwe-packer. Uma kuqhathaniswa nokuqhekeka kwezendlalelo ezilandelanayo okujwayelekile, kuthuthukisa ukusebenza kahle kokusebenza ngaphezu kuka-40%, kuqinisekisa ngokuphelele ukusebenza kahle kokusebenza.
Lo msebenzi wokuhlukanisa owenziwe ngezinga eliphezulu, ukusebenza kahle okuphezulu, kanye nekhwalithi ephezulu uqhubekisele phambili amakhono ezobuchwepheshe wokuvuselela ukuhlukanisa kwevolumetric futhi waqoqa isipiliyoni esibalulekile sokuthuthukiswa okuphumelelayo kwamachibi anomoya omncane eBohai Oilfield.
Ukukhipha uwoyela 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. Sizibophezele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yemboni kawoyela, igesi, kanye ne-petrochemical. Uhlu lwethu lomkhiqizo olusebenza kahle kakhulu luhlanganisa ama-hydrocyclone okukhipha uwoyela/amanzi, ama-desander ezinhlayiya ezincane kakhulu, kanye namayunithi okuntanta acindezelwe. Sinikeza izixazululo eziphelele ezifakwe ku-skid futhi sinikeza nokulungiswa kabusha kwemishini yenkampani yangaphandle kanye nezinsizakalo zangemuva kokuthengisa. Sibambe amapentente amaningi angaphansi kwethu futhi sisebenza ngohlelo lokuphatha oluqinisekisiwe lwe-DNV-GL ISO-9001, ISO-14001, kanye ne-ISO-45001, siletha izixazululo zenqubo ezithuthukisiwe, ukuklama komkhiqizo okunembayo, ukugcinwa okuqinile kwezicaciso zobunjiniyela, kanye nokwesekwa okuqhubekayo kokusebenza.
Ithu ama-cyclone desanders asebenza kahle 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 kusetshenziswe i-miscible flooding emingxuneni enokungena okuncane, isixazululo esibalulekile sokuthuthukisa ukubuyiselwa kukaphethiloli ezindaweni eziyinselele. Kungenjalo, zingakwazi ukwelapha amanzi akhiqiziwe, zisuse 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 yidivayisi yokuhlukanisa uketshezi-okuqinile esebenzisa umgomo ophumelelayo we-centrifugal ukuhlukanisa izinto ezingcolile ezintantayo—njengezinto eziqinile emanzini akhiqiziwe, amanzi olwandle, i-condensate, izinhlayiya ezinhle eketshezini elinamandla aphezulu, kanye nomgqomo we-catalyst kuma-reactors—kusuka eketshezini (uketshezi, igesi, noma ingxube yegesi-uketshezi). Iyasusa kahle izinhlayiya eziqinile ezinosayizi ongaphansi kuya ku-2 microns (ngokusebenza okungu-98%) noma ezincane.
I-Desander Enezinga Eliphezulu Kakhulu Yeziyingana Ezincane Kakhuluihambisa ukusebenza kahle kakhulu ekususeni isihlabathi, ikwazi ukususa izinhlayiya eziqinile ezifika ku-2 microns. Le mishini inendawo encane, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inomjikelezo wokuphila cishe iminyaka engu-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 kumapulatifomu e-wellhead nawokukhiqiza. Ahlinzeka ngokususwa okuphumelelayo kwezinto eziqinile kuwo igesi, uketshezi lokukhiqiza, ne-condensate, futhi abalulekile ekuhlanzweni kwamanzi olwandle, ekuvikelweni komjikelezo wokukhiqiza, nasezinhlelweni zokujova/ukugcwalisa amanzi.
Ngaphandle kwama-desanders, i-SAGA inikeza iqoqo lobuchwepheshe bokuhlukanisa obudume kakhulu. Umugqa womkhiqizo wethu uhlanganisaizinhlelo zembrane zokususa i-CO₂ egazini lemvelo, ama-hydrocyclones okukhipha uwoyela, amajenethi okuhlanganisa aphezulu (CFUs), ukususwa kwesihlabathi segesi yomlotha，Iphakethe lokukhipha amanzi eline-cyclonic elokwelapha amanzi akhiqiziwefuthi ama-hydrocyclone amaningi, ahlinzeka ngezixazululo eziphelele izinselelo eziyinqaba zemboni.
