SINOPEC's Deepest Coalbed Methane Zoo, Yangjia 1HF, ua tiav tiav

Yang Coal 1HF qhov dej yog thawj qhov sib sib zog nqus coalbed methane txoj kev tshawb nrhiav kab rov tav zoo hauv Suav teb, siv lub ntsiab coal seam nyob rau hauv Taiyuan Formation, Tai seem, raws li lub hom phiaj tseem ceeb ntawm txheej txheej, tshawb xyuas cov peev txheej ntawm cov khoom sib sib zog nqus coalbed methane nyob rau sab sauv Paleozoic ciam teb ntawm Da Niu Di gas teb, thiab siv zog kom paub txog kev ua tiav hauv kev tsim khoom.

Raws li ib txoj haujlwm tseem ceeb ntawm North Tuam Tshoj Roj & Roj Tuam Txhab rau "kev sib sib zog nqus coalbed methane project" thiab ib txoj haujlwm tseem ceeb ntawm Sinopec hauv 2022, kev xa tawm thiab kev tsim kho ntawm Yangxiang Coal 1HF hauv Daniu cheeb tsam yog qhov tseem ceeb ntawm cov tswv yim tseem ceeb. Raws li thawj qhov kev pheej hmoo tshawb nrhiav qhov zoo ntawm North Tuam Tshoj ceg ntawm "Deep Earth Project", nws ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav qhov sib sib zog nqus coalbed methane, txheeb xyuas cov txheej txheem kev ua tau zoo ntawm cov dej sib txuas kab rov tav, tshawb nrhiav kev tsim khoom tiav thiab paub txog kev ua tiav hauv kev tsim khoom ntawm North Tuam Tshoj. Ceg.

Cov chaw roj thiab roj uas muaj los ntawm North China Oil & Gas Company nyob rau hauv Ordos Basin yog nplua nuj nyob rau hauv cov khoom siv thee, tshwj xeeb tshaj yog cov coal txaj uas tsis tuaj yeem mined los ntawm cov cuab yeej siv niaj hnub mus rau qhov tob ntawm 2, 000 meters, thiab kev txhim kho thiab kev siv thee txaj methane cov peev txheej tau dhau los ua "tsis muaj txiv neej thaj av".

Txhawm rau nrhiav kev txhim kho kom ruaj khov thiab muaj txiaj ntsig zoo ntawm kev lag luam, North China Oil & Gas ceg tau npaj cov qauv kev tsim kho kev lag luam ntawm ntau yam kev loj hlob thiab kev siv cov peev txheej, noj cov kev loj hlob thiab kev siv cov sib sib zog nqus coalbed methane raws li txoj haujlwm nyiam, thiab kawg. xyoo, nws tau ua ib qho kev sim coalbed methane siv lub qhov dej qub hauv Da Niu Di roj av, nrog rau kev tsim cov coalbed methane fracturing siv rau ntawm qhov dej tshawb nrhiav hauv South China North Basin, uas ob qho tib si ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov roj av.

Txhawm rau kom paub ntxiv txog qhov kev tshawb nrhiav muaj peev xwm ntawm kev sib sib zog nqus coalbed methane thiab txhawb txoj kev loj hlob ntawm kev sib sib zog nqus coalbed methane, cov ceg tau siv qhov kev ntsuam xyuas thawj kab rov tav no tsom rau cov coalbed hauv kev cia siab tias yuav muaj kev tsim tawm los ntawm kev nthuav dav cov coalbed methane ntws hauv cheeb tsam. Txhawm rau kom ntseeg tau tias kev tsim kho ntawm lub qhov dej zoo, cov kws tshaj lij ntawm lub koom haum engineering ntawm ceg tau xaiv thiab xa cov pob txha rov qab rau kev txhawb nqa ntawm qhov chaw thaum lub sijhawm ua haujlwm ntawm sab drilling thiab cementing kom ntseeg tau tias kev ua haujlwm siab, thiab kuaj cov av nkos. ib los ntawm ib qho los xyuas kom meej qhov kev hloov dua siab tshiab ntawm sab-drilling drilling kua los lav qhov kev nyab xeeb ntawm qhov dej.

Tom qab kev koom tes ntawm ntau lub koom haum, kev sib txuas lus thiab kev sib koom ua ke, thiab kev soj ntsuam ntawm qhov chaw thiab kev txiav txim siab, qhov drilling thiab ua tiav ntawm Yang Coal 1HF qhov dej tau ua tiav zoo, uas ua kom lub hauv paus ruaj khov rau kev pib zoo thiab cov kauj ruam zoo hauv qhov tshiab. xyoo kev tshawb nrhiav coalbed methane.
