Kutholakale insimu enkulu ye-deep coalbed methane e-Shaanxi, e-China!
▲ Imisebenzi yokumba iyaqhubeka emkhakheni we-Yandong coalbed methane (CBM) we-Yanchang Petroleum.
NgoJulayi 13, i-Yanchang Group yamemezela ukuthi izinqolobane eziqinisekisiwe zomkhakha we-Yandong coalbed methane (CBM), ezithunyelwe yinkampani, zidlule ekubuyekezweni nasekugcinweni koMnyango Wezinsiza Zemvelo, kanti izinqolobane zokuma komhlaba zilinganiselwa cishe kumamitha ayizigidi eziyizinkulungwane ezingama-53.7. Isifundazwe sase-Shaanxi sithole omunye umkhakha omkhulu we-CBM ojulile.
Umkhakha we-Yandong CBM, otholakala e-Yanchang County nase-Yichuan County, ungumkhakha wokuqala omkhulu we-CBM ojulile oqinisekiswe yinkampani yesifundazwe e-Shaanxi. Ukujula kwawo kudlula amamitha ayi-2,000, futhi uyisizinda se-CBM esijulile esiyisici esithi "sizihlanganisa futhi sizigcina". Ngokwezilinganiso zochwepheshe, izinqolobane eziqinisekisiwe zomkhakha we-Yandong CBM zinikeza isisekelo sokwakha umthamo wokukhiqiza waminyaka yonke ongama-cubic metres ayizigidi eziyizinkulungwane ezingama-800 kuya kweziyizigidi eziyizinkulungwane eziyi-1 we-CBM.
Insimu ye-CBM iyinsimu "yegesi yemvelo" efihliwe emgodini wamalahle, ne-methane eyingxenye yayo eyinhloko, eyaziwa ngokuthi "igesi". Ngemva kokukhishwa nokusetshenziswa, i-CBM ingaba uphethiloli ohlanzekile, hhayi nje ukuqinisekisa ukuphepha emayini yamalahle kodwa futhi isebenze njengomthombo wamandla.
Ngenxa yokungcwatshwa kwayo okujulile nezimo eziyinkimbinkimbi zokwakheka komhlaba, ukukhipha i-CBM ejulile kunzima kakhulu. Ithimba locwaningo lase-Yanchang Petroleum lenze um пропозицій omusha wethiyori yokunqwabelana futhi lathuthukisa izinhlelo zokumba kanye nokukhiqiza ngokuvumelana nalokho. Ngo-2024, umthombo wabo i-Well Chang 91 X1 (umthombo oqondile) wenza kahle kakhulu ekuhlolweni kwegesi engqimbeni eyodwa, lapho umkhiqizo omkhulu wegesi ngosuku wedlula izigidi eziyi-106,000 cubic metres, okwenza irekhodi elisha likazwelonke lomkhiqizo omkhulu ngosuku emthonjeni oqondile/omile we-CBM ejulile.
Ngemva kweminyaka engaphezu kwemithathu yocwaningo, ithimba le-Yanchang Petroleum lacacisa imithetho yokunotha nokunqwabelana kwe-CBM ejulile e-Ordos Basin eseningizimu-mpumalanga, lakha uhlelo oluhlanganisiwe lokumba nokuqhekeka nokukhiqiza olusebenza ezinhlotsheni ezahlukene zemithombo, futhi lwenza intuthuko eyingqophamlando ekukhiqizeni umthombo owodwa.
ISiZulu:
IShaanxi iyisifundazwe esikhulu ekugcinweni kwezinsiza zamalahle kanye nokukhiqizwa, kanti izinsiza ze-CBM zisatshalaliswa ikakhulukazi ezindaweni zezimayini. Ngo-2023, i-CNOOC yathola insimu enkulu ye-CBM—i-Shenfu Deep CBM Giant Field—e-Yulin, enyakatho yeShaanxi, enezinqolobane zomhlaba ezingaphezu kuka-110 billion cubic metres. Lokhu kwaba ukutholwa kokuqala kwensimu ye-CBM ejulile eyikhulu lezigidi eziyizigidi eziyizinkulungwane eShayina. NgoMashi walo nyaka, iShaanxi yakhipha imibono yokuqalisa mayelana nokuqhubekisela phambili ukukhishwa nokusetshenziswa kwe-CBM (igesi yamalahle), icacisa ukuthi izokhulisa ukwesekwa kwezimali, iqinise ukuphathwa kokukhishwa nokusetshenziswa, ithuthukise izinqubomgomo zentengo nokuxhumeka kugridi, futhi isheshise ukusungulwa kobuchwepheshe ukuze ikhulise ukuthuthukiswa nokusetshenziswa kwe-CBM esifundazweni, ngaleyo ndlela inikeze ukwesekwa okukhulu ekuvikelekeni kwamandla kuzwelonke.
