Ib qho tshiab loj Unconventional zog hloov Block tau ntxiv rau Yan'an Gas Field

Lub tuam txhab Shaanxi Yanchang Gasfield tau ua tiav lub qhov dej hauv cov bauxite txheej ntawm Benxi Tsim nyob rau sab hnub tuaj ntawm Yan'an Gasfield, nrog rau qhov tsis muaj kev cuam tshuam ntau dua 20, 000 cubic meters ib hnub, uas ntxiv qhia tau hais tias lub bauxite reservoir ntawm Benxi Formation muaj kev tshawb nrhiav zoo thiab xav tias yuav dhau los ua ib qho chaw tseem ceeb rau kev txhim kho kom ruaj khov ntawm Yan'an Gasfield.

Nyob rau hauv xyoo tas los no, txhawm rau tsim thiab ua kom ruaj khov 15 billion cubic meters ntawm natural gas muaj peev xwm, lub tuam txhab tau ua kom nrawm nrawm ntawm kev tshawb nrhiav cov peev txheej tsis zoo raws li kev tshawb nrhiav cov peev txheej, txuas ntxiv mus tob rau kev tshawb fawb ntawm cov roj av sib xyaw thiab ua kom muaj txiaj ntsig zoo. kev cai lij choj, nquag nthuav cov pab pawg, thiab tshawb nrhiav thiab txhawb kev tshawb nrhiav "txoj kev tshiab thiab cov teb tshiab". Benxi Formation bauxite yog lub reservoir nrog kev loj hlob zoo thiab muaj kev tshawb nrhiav zoo heev.

Txhawm rau txuas ntxiv kais cov roj muaj peev xwm ntawm bauxite, lub tuam txhab cov roj tsim cov nroj tsuag No. 1 ua ke cov ntaub ntawv geological tsom xam, cov yam ntxwv ntawm lub pas dej, thiab kev tsim kho engineering zoo tshaj plaws, thiab tau txais ib qho "loj-scale pre-acid pretreatment + tag nrho cov txheej txheem ceev-dissolving. slick dej fracturing kua" ua ke system los tsim ib "tsawg xuab zeb piv, siab mesh" fracturing txoj kev npaj; Thaum lub sij hawm kev tsim kho, los ntawm kev tswj xyuas cov ntaub ntawv nkag mus rau hauv lub qhov dej kom zoo, ua tib zoo saib xyuas cov txheej txheem tsim kho, xyuas cov txheej txheem tseem ceeb, tswj xyuas cov ntsiab lus tseem ceeb, thiab nruj me ntsis xyuas cov ntaub ntawv yooj yim, tom qab 2 teev ntawm kev tsim kho, kev tshawb nrhiav ib zaug. tau ua tiav, tshawb xyuas ntxiv qhov peev xwm ntawm Benxi Formation bauxite.
