Inkambu ye-methane yamalahle ejulile engamabhiliyoni ayi-100 e-cubic meter ifakazelwe e-Sanjiaobei Block, e-Ordos Basin
I-PetroChina iveze ukuthi iSanjiaobei Block eLüliang City, eSifundazweni saseShanxi, yengeze ngaphezu kwezigidigidi eziyi-100 zamamitha ayikhyubhu wamarezervi e-geological aqinisekisiwe e-coalbed methane. Amarezervi asanda kwengetwa anendawo ye-gas-bearing ehlangene engama-411.5 square kilometers, nemigqa yamalahle egqitshwe ekujuleni okungamamitha ayi-1,900 kuya ku-2,150; umgomo wokuhlola ungaphansi kwemithombo ye-deep coalbed methane emaphethelweni asempumalanga ye-Oldos Basin.
I-Sanjiaobei Block itholakala empumalanga ye-Ordos Basin, endaweni yaseLinxian eLüliang, eShanxi. Idatha yokuhlola yomphakathi ikhombisa ukuthi izikhawu eziqondiwe ze-deep coalbed methane (CBM) kule ndawo zisatshalaliswa ngaphansi kuka-1,500 m. Izinsiza ze-deep CBM ezazihlolwe ngaphambilini zazicishe zibe yizigidi eziyizinkulungwane eziyikhulu namashumi ayisithupha zama-cubic meters. Ngesikhathi sesigaba sokuhlola, ukubhoboza, ukuqhekeza, nokuhlola ukukhiqiza kuye kwenziwa, futhi amanye amaqula aqondisiwe e-deep CBM athole umkhiqizo ophezulu wansuku zonke wegesi ozinzile ongaphezu kwama-cubic meters angama-20,000. Ukulungiselelwa kohlelo lokuthuthukiswa kwe-deep CBM kwe-Sanjiaobei Block, olwaqalwa ngo-2024, kuhlanganisa indawo engaba ngama-square kilometers angama-407. Uhlelo kulindeleke ukuthi lube namandla okukhiqiza angaba yizigidi eziyizinkulungwane eziyishumi nesishiyagalombili zama-cubic meters ngonyaka, futhi ukulungiselelwa kwalo kuhlanganisa i-geology kanye nobunjiniyela be-gas reservoir, ubunjiniyela bokubhoboza, ubunjiniyela bokukhiqiza igesi, ubunjiniyela obungaphezulu, kanye nokuhlolwa kwezomnotho.
I-Sanjiaobei iphinde ibe phakathi kwezikhala ezifakwe yi-National Energy Administration ezindaweni ezibalulekile zokwandisa iziqukathi ze-CBM nokwakha umthamo wokukhiqiza olandelanayo empumalanga ye-Ordos Basin. I-Action Plan for Increasing CBM Reserves and Production in the Eastern Ordos Basin (2026–2030), eyakhishwa ngoJulayi 2026, iphakamisa ukwenza izifundo mayelana namaphethini okunqwabelana, izindlela zokucebisa, kanye nokuhlolwa kwezindawo ezinhle kwezokwakheka komhlaba nobunjiniyela e-Sanjiaobei nezinye izikhala, ukusheshisa ukuhlolwa kwezindawo ezinokuhlolwa okuphansi, kanye nokuhambisa iziqukathi eziqinisekisiwe ngokushesha. Esigabeni sokuthuthukiswa, idinga ukuqinisa ukuhlolwa kokukhiqizwa kwe-CBM e-Sanjiaobei, ukuthuthukisa ngokulandelana ukusetshenziswa komthamo wokukhiqiza, kanye nokwenza izivivinyo zemithombo evundlile enezigaba ezinde kakhulu zomhlandla.
Ngokohlelo lokusebenza, ngonyaka ka-2030, izinqolobane ze-geological ezifakazelwe ze-CBM eMpumalanga ye-Ordos Basin zizokhula ngaphezu kwezigidigidi ezingama-600 zama-cubic metres uma kuqhathaniswa nokuphela kwe-14th Five-Year Plan, futhi ukukhiqizwa kwe-CBM kuzofinyelela ezigidigidini eziyishumi nesishiyagalombili zama-cubic metres, kanti ukukhiqizwa kwe-CBM ejulile kuzodlula ezigidigidini eziyishumi nesithupha zama-cubic metres. Izinqolobane ezifakazelwe ezisanda kufakwa eSanjiaobei kulokhu zimelela umphumela wakamuva wokuhlola wokukhula okuqhubekayo kwezinqolobane ze-CBM ejulile kulesi sifunda. Umsebenzi olandelayo usungene esigabeni esixhumanisa ukuhlolwa kwezinqolobane nohlelo lokuthuthukisa, ukuhlolwa kokuhlolwa kokukhiqiza, kanye nokuhlelwa komthamo wokukhiqiza.
Ukukhiqizwa kukawoyela negesi yemvelo akunakwenzeka ngaphandle kwemishini yokuhlukanisa.
I-Shanghai SAGA Offshore Engineering Co., Ltd., eyasungulwa eShanghai ngo-2016, iyibhizinisi lobuchwepheshe besimanje elihlanganisa ucwaningo nokuthuthukiswa, ukuklama, ukukhiqiza, kanye nesevisi. Sizinikele ekuthuthukiseni imishini yokuhlukanisa nokuhlunga yemboni kawoyela, igesi, kanye ne-petrochemical. Uhlu lwethu lwemikhiqizo esebenza ngempumelelo lufaka ama-hydrocyclone okususa uwoyela/ukususa amanzi, ama-desander ezinhlayiya ezincane ezingama-micron, kanye namayunithi e-flotation ahlangene. Sihlinzeka ngezixazululo eziphelele ezifakwe kuma-skid futhi siphinde sinikeze ngokulungiswa kwemishini yabanye kanye nezinsizakalo zangemva kokuthengisa. Sinezicelo zobunikazi eziningi kanye nohlelo lokuphatha olugunyazwe yi-DNV-GL ISO-9001, ISO-14001, kanye ne-ISO-45001, sinikeza izixazululo zenqubo ezithuthukisiwe, ukuklama komkhiqizo okunembile, ukulandela ngokuqinile izincazelo zobunjiniyela, kanye nokusekelwa okusebenzayo okuqhubekayo.
I-high-efficiency cyclone desanders, aduma ngezinga lawo lokwehlukanisa eliyingqayizivele elingama-98%, athole ukuqashelwa kubaholi bamandla omhlaba wonke. Akhiwe ngezinto zobumba ezingagugi ezithuthukile, la mayunithi afinyelela ukususwa okungama-98% kwezinhlayiyana ezincane kufika kuma-0.5 microns emisakazweni yegesi. Leli khono lenza ukuthi igesi ekhiqiziwe iphinde ifakwe ukuze kusetshenziswe i-miscible flooding emachibini anokungena okuphansi, okuyisixazululo esibalulekile sokuthuthukisa ukukhishwa kukawoyela ezindaweni eziyinselele. Ngakolunye uhlangothi, zingacubungula amanzi akhiqiziwe, zisuse ama-98% ezinhlayiyana ezinkulu kune-2 microns ukuze zifakwe kabusha ngqo, ngaleyo ndlela zikhulise ukusebenza kahle kwe-water-flood kuyilapho zinciphisa umthelela kwezemvelo.
Umkhiqizo wethu omusha—I-High Efficiency Ultra-Fine Particle Desander iyithuluzi lokwehlukanisa uketshezi nokuqinile elisebenzisa umgomo osebenza kahle we-centrifugal ukwehlukanisa ukungcola okulengayo—njengezinto eziqinile emanzini akhiqiziwe, amanzi olwandle, i-condensate, izinhlayiya ezincane oketshezini olune-viscosity ephezulu, kanye ne-catalyst powder kuma-reactor—kuketshezi (uketshezi, amagesi, noma ingxube yoketshezi negesi). Isusa ngempumelelo izinhlayiya eziqinile ezinosayizi ofika kuma-micron angu-2 (ngempumelelo engu-98%) noma ngaphansi.
Isihlukanisi Sezinhlayiya Ezincane Kakhulu Esisebenza Ngempumelelo Ephezulu sinikeza ukusebenza kahle okuphezulu kokususa isihlabathi, okukwazi ukususa izinhlayiya eziqinile ezifika kuma-micron angu-2. Imishini inendawo encane yokuma, ayidingi amandla angaphandle noma izithako zamakhemikhali, futhi inempilo yokusebenza cishe iminyaka engu-20. Inikeza amandla okukhipha isihlabathi ku-inthanethi ngaphandle kwesidingo sokumisa ukukhiqiza.
Kufakazelwe emikhakheni emikhulu yomhlaba esetshenziswa yi-CNOOC, CNPC, Petronas, nabanye kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa kumapulatifomu ewellhead nawokukhiqiza. Ahlinzeka ngokususwa okuqinisekile kwezinto eziqinile kugesi, uketshezi lwemithombo, ne-condensate, futhi abalulekile ekuhlanzeni amanzi olwandle, ekuvikeleni imifudlana yokukhiqiza, nasezinhlelweni zokujova nokugcwalisa amanzi.
Ngaphandle kwama-desander, i-SAGA inikeza iqoqo lobuchwepheshe bokuhlukanisa obudumile. Umugqa wethu wemikhiqizo uhlanganisa amasistimu e-membrane okususa i-CO₂ kugesi yemvelo, ama-hydrocyclone okususa uwoyela, high-performance compact flotation units (CFUs), Ukususa isihlabathi kugesi we-shale, Iphakethe le-cyclonic dewatering elinokwelashwa kwamanzi akhiqiziwe, futhi ama-hydrocyclone anamagumbi amaningi, okuletha izixazululo eziphelele ezinseleleni ezinzima zemboni.
