Ukubhola kwe-shale oil e-Xinjiang Oilfield kudlula amarekhodi amabili asekhaya
NgoMeyi 3, umgodi i-JHW92-12 we nsiza kawoyela we-shale i-Jimsar esifundeni sokusebenza sikawoyela i-Jiqing sikawoyela i-Xinjiang, uqede ngempumelelo. Ngobuchwepheshe obuqinile nokwakhiwa okuphumelelayo, waphula amarekhodi amabili okugojwa kukayela kawoyela ezweni, kwengeza umdlandla omkhulu ekuthuthukisweni okuphumelelayo kwesifunda sikazwelonke sokubonisa ukayela we-shale.
Umthombo unobunzima obuphelele obungamamitha angu-6,223 futhi waqedwa ngezikhathi ezimbili nje. Phakathi kwazo, ingxenye eqondile, ingxenye eyihlanekelwe, nengxenye eyindilinga kwakugojelwe "ngesikhathi esisodwa," kunezinyathelo ezingamamitha angu-4,223, kwaphula irekhodi lasekhaya lezinyathelo ezinde kakhulu "ngesikhathi esisodwa" ekugojeleni uwoyela we-shale. Isikhathi sonke sokugojela umthombo sasingu-13.67 nje izinsuku, kwabeka irekhodi elisha lasekhaya lesikhathi esifushane kakhulu sokugojela imithombo kawoyela we-shale esijuleni esifanayo, okuholela embonini kokubili ekusebenzeni kahle kokwakhiwa kanye nekhwalithi yobunjiniyela.
Indawo Yokubonisa Uwoyela We-Shale YaseJimsar yindawo yokuqala kazwelonke yaseShayina yokubonisa uwoyela we-shale wezwekazi futhi iyindawo ebalulekile yokwandisa izinto ezigciniwe kanye nokukhiqizwa kukaphethiloli negesi okungajwayelekile. Indawo yokugcina uwoyela kule ndawo ingcwabe kakhulu, inobuchashile obuyinkimbinkimbi, futhi inokungena okuncane kakhulu. Ngesikhathi sokwakhiwa, izinkinga ezifana nokulahleka komhlaba kanye nobunzima ekulawuleni umzila zivame ukwenzeka, okubeka izidingo eziphakeme kakhulu kubuchwepheshe bokubhola kanye nokuphathwa kwendawo. Ukuqedwa ngempumelelo kwalo mkhono kubonise ngokugcwele ukuthuthuka nokwethembeka kwesistimu yokusebenza ngokubambisana kanye nobuchwepheshe obuhle kakhulu bokubhola ngokushesha, okunikeza umuzwa ongaphindeka futhi ongakhuphuka wokuthuthukiswa okukhulu kukaphethiloli we-shale ojule kakhulu eShayina.
Ukuze kufezekiswe ukugawulwa okuphephile nokusebenza kahle, ithimba lephrojekthi lasungula indlela yokusebenzisana esebenza kahle "yokuhola komnyango wokwakha, ukwenziwa ngumnyango wokwakha, ukwesekwa ngumnyango wezobuchwepheshe," okwenza ukulawulwa okuyindilinga kuyo yonke inqubo. Esigabeni sokuqala, ochwepheshe abavela eminyangweni eminingana bahlangana ukuze baxoxe ngezihloko ukuze bahlaziye kahle imodeli yokulahleka kwezinto eziphilayo, kuncishiswe ubungozi bokwakha kusukela emthonjeni; ngesikhathi esifanayo kwenziwa uhlelo lokugawula, kwamiswa ngokwesayensi ukukhethwa kwe-bit kanye nomhlangano we-bottom hole, futhi kwasetshenziswa inhlanganisela "ye-rotary steerable + screw" esigabeni sesibili ukuze kwandiswe ngisho nesivinini sokugawula.
Ukukhiqizwa kukayela negesi yemvelo akukwazi ukufezekiswa 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. Umkhiqizo wethu wokusebenza kahle uphelele uhlanganisa ama-hydrocyclone okukhipha uwoyela/amanzi, ama-desander ezinhlayiya ezincane kakhulu, kanye namayunithi okuhlanganisa aqinile. Sihlinzeka ngezixazululo eziphelele ezifakwe ku-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, sihlinzeka ngezixazululo zenqubo ezithuthukisiwe, ukuklama komkhiqizo okunembayo, ukuthobela ngokuqinile imininingwane yobunjiniyela, kanye nokusekelwa okuqhubekayo kokusebenza.
Yethu,i-cyclone desanders ephumelela kakhulu, ezaziwa ngezinga lazo elihle kakhulu lokuhlukanisa elingu-98%, zithole ukubuyekezwa okuvela kubaholi bamandla aphesheya kwezilwandle. Zakhiwe nge-ceramics ethuthukisiwe ekwazi ukumelana nokuguga, lezi zinhlelo zikwazi ukususa 98% wezinhlayiya ezincane njengama-micron angu-0.5 emifudlaneni yegesi. Leli khono lenza ukuthi igesi ekhiqiziwe ingene kabusha ukuze isetshenziswe ekugcwaliseni okuxubile kumadwala anomoya ophansi, isixazululo esibalulekile sokuthuthukisa ukubuyisa uwoyela kumadwala anzima. Kungenjalo, zingakwazi ukwelapha amanzi akhiqiziwe, zisuse u-98% wezinhlayiya ezinkulu kune-micron engu-2 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 umgomo ophumelelayo we-centrifugal ukuhlukanisa izinto ezingcolile ezintantayo—njengezinto eziqinile emanzini akhiqiziwe, amanzi olwandle, i-condensate, izinhlayiya ezinhle eketsheni elinamandla aphezulu, kanye nomgqomo we-catalyst kuma-reactor—kusuka eketsheni (uketshezi, igesi, noma ingxube yoketshezi negesi). Iyasusa kahle izinhlayiya eziqinile ezinosayizi abancane njengama-micron amabili (ngokuphumelela okungu-98%) noma ngaphansi.
I-High Efficiency Ultra-Fine Particle Desanderinikeza ukuphumelela okuphezulu kokususwa kwesihlabathi, ekwazi ukususa izinhlayiya eziqinile ezincane njengama-micron amabili. Le mishini inendawo encane, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inomjikelezo wokuphila cishe weminyaka engu-20. Inikeza ikhono lokukhipha 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 omthombo womoya kanye nawokukhiqiza. Ahlinzeka ngokususwa okuthembekile kwezinto eziqinile emoyeni, uketshezi lomthombo, 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 obuncomekayo. Umugqa womkhiqizo wethu uhlanganisa izinhlelo zamamembrane zokususa i-CO₂ yegesi yemvelo, ama-hydrocyclone okukhipha uwoyela, i-high-performance compact flotation units (CFUs), ukususwa kwesihlabathi segesi ye-shale, Iphakethe lokukhipha amanzi nge-cyclonic elokwelapha amanzi akhiqiziwe, kanye ama-hydrocyclone amaningi, ahlinzeka ngezixazululo eziphelele izinselelo eziqinile zemboni.
