Hla Dhau Los Ntawm Cheeb Tsam Txwv Tsis Pub Muaj Peev Xwm Txhua Xyoo Ntawm Kuv Lub Tebchaws Qhov Loj Tshaj Plaws Coalbed Methane Teb ncav cuag 2.5 billion Cubic Meters
Apr 04, 2024
Thaum Lub Peb Hlis 26, cov roj av niaj hnub ntawm lub taub hau ntawm Qinshui coalbed methane teb hauv North China Oilfield tau tshaj 7 lab cubic meters, kos npe rau txhua xyoo muaj peev xwm ntawm kuv lub teb chaws loj tshaj plaws coalbed methane teb mus txog 2.5 billion cubic meters.
Coalbed methane, feem ntau hu ua roj, yog qhov txaus ntshai "killer" hauv cov thee mining. Nws tseem yog lub zog huv thiab cov khoom siv tswv yim uas muaj cov txiaj ntsig calorific siab dua li cov thee dav dav thiab ua rau yuav luag tsis muaj roj pov tseg thaum hlawv. Lub teb chaws thoob ntiaj teb tab tom sib tw los tsim thiab siv nws.
Huabei Oilfield tau tsom mus rau kev cia siab rau tus kheej thiab kev cia siab rau tus kheej nrog kev tshawb fawb thiab thev naus laus zis, thiab tau tsim kho tshiab thiab daws cov teeb meem tseem ceeb rau ntau xyoo. Nws tau tsim Tuam Tshoj Petroleum thawj qhov kev sim mining hauv paus hauv kev ua haujlwm ntawm coalbed methane. Nws tau tsim cov thee-theem-qib coal seams hauv high-coal-rank reservoirs uas feem ntau suav hais tias yog "qhov txwv tsis pub" hauv kev tshawb nrhiav thiab kev tsim kho. Txoj kev txhim kho huab cua tau ntim cov khoob hauv tsev thiab txawv teb chaws thiab yeej National Science thiab Technology Progress Award. Kev txhawb nqa los ntawm txoj kev txhim kho tshiab thiab thev naus laus zis, Huabei Oilfield tau tsim kuv lub teb chaws thawj qhov digital thiab loj-loj coal txaj methane teb, nrog rau qhov feem ntau ntawm cov qhov dej zoo tshaj 49% thiab cov peev txheej tsim tau ntau dua 95%.
Txhawm rau txuas ntxiv tso tawm lub peev xwm ntau lawm ntawm Qinshui coalbed methane teb, North China Oilfield tau tsim qhov kev xa tawm los ntawm Mabi Kev Koom Tes Block mus rau West-East Gas Pipeline Qinshui Water Pressurized Gas Station. Thaum Lub Yim Hli 2023, qhov thib ob lub raj xa dej los ntawm Qinshui coalbed methane teb mus rau lub teb chaws qaum qaum pipeline network tau ua tiav kev sib txuas, uas tuaj yeem ua kom cov kav dej xa tawm muaj peev xwm nce ntxiv los ntawm 1.5 billion cubic meters hauv ib xyoos, tsim ib qho tshiab dual-channel export qauv ntawm coalbed methane. Raws li qhov tshwm sim, lub peev xwm xa tawm ntawm Jinnan coalbed methane pipeline hauv Huabei Oilfield nce mus txog 3.5 billion cubic meters hauv ib xyoos, ntxiv kev ntseeg siab rau lub caij ntuj no cov roj av hauv thaj tsam Beijing-Tianjin-Hebei, Shanxi, Henan, Shandong, Jiangsu thiab lwm cheeb tsam.
Txij li thaum pib ntawm lub xyoo no, Huabei Oilfield tau ntxiv dag zog rau kev tsim muaj peev xwm ntawm Zhengzhuang, Fanzhuang, Mabidong thiab lwm cov blocks, txhawb kev txo qis kev tswj cov dej qub, txuas ntxiv kev tsim cov qhov dej tshiab thiab kev ntsuas los ua kom cov khoom siv qis qis, thiab tau siv "plaub loj kev ruaj khov thiab kev tsim khoom nce ntxiv" thiab "tsib qhov kev txhim kho kev lag luam loj" thiab "kev hloov pauv thiab hloov kho qhov project", tso lub hauv paus ruaj khov thiab nce kev tsim cov roj av.
