Thawj pawg hauv Suav teb! PetroChina ua CCUS-EGR Pilot Test hauv Volcanic Gas Reservoirs
Jun 07, 2024
Lub Plaub Hlis 23, tom qab ib nrab xyoo ntawm kev tshawb fawb thiab kev tsim kho, qhov kev sim sim ntawm CCUS-EGR teb kev sim hauv cov roj hluav taws xob hluav taws xob ua los ntawm Tuam Tshoj National Petroleum Corporation hauv Changling Gas Field ntawm Jilin Oilfield tau nce mus rau theem ntawm kev ua qauv qhia thiab parameter optimization.
Kev tsom mus rau lub teb chaws "dual carbon" lub hom phiaj, Pab Pawg tau tsim "peb-kauj ruam" phiaj xwm ntsuab nrog cov hom phiaj meej. CCUS-EGR, raws li lub tswv yim ua tiav thiab kev lag luam ntsuab thiab cov pa roj carbon tsawg, yog ib txoj hauv kev tseem ceeb kom ua tiav cov pa roj carbon ntau hauv 2025, "zero" emissions hauv 2050 thiab lub tuam txhab hloov pauv ntsuab. PetroChina tau txhawb nqa kev lag luam thiab kev tshawb fawb ntawm CCUS. Tam sim no, CO2 roj rov qab txhim kho thev naus laus zis, uas yog CCUS-EOR, tau tsim cov kev paub zoo tshaj plaws, thiab cov roj reservoir txhim kho kev siv tshuab, CCUS-EGR, nyuam qhuav pib. Lwm yam thev naus laus zis hauv tsev thiab txawv teb chaws tseem nyob rau theem kev tshawb fawb theoretical, thiab kev xyaum ua haujlwm yog qhov yuav tsum tau ceev nrooj txhawm rau txhawm rau txhim kho kev lag luam.
CCUS-EGR yuav tsum tau tso siab rau kev sib koom ua ke ntawm ntau yam kev qhuab qhia xws li kev sim sab hauv tsev, kev tshawb fawb txog geological, kev sib txuam, thiab kev ntsuam xyuas nyiaj txiag los tsim cov kev daws teeb meem rau tag nrho cov txheej txheem, thiab ua cov kev sim thaiv hauv ib puag ncig nrog cov kav dej ua tiav, cov pa roj carbon ntau txaus, thiab cov peev txheej roj thiab roj zoo dua. Changling Gas Field yog "ballast pob zeb" rau kev ruaj khov thiab nce cov pa roj hauv Jilin Oilfield. Cov txheej txheem roj tseem ceeb, Yingcheng Formation, yog ib tus neeg sawv cev ntawm cov pob zeb tawg hauv qab dej volcanic pob zeb gas reservoirs. Nws yog qhov chaw sim zoo rau CCUS-EGR txhawm rau txhim kho cov roj rov qab, thiab xav tias yuav ua tiav qhov kev sib tw loj hauv kev txhim kho cov roj rov qab los ntawm kev txhaj tshuaj carbon dioxide.
Daqingzijing Oilfield CCUS-EOR industrialization xeem cheeb tsam tau tsim nyob rau hauv Qingshankou Tsim nyob rau sab sauv ntawm Changling Gas Field. Raws li kev sib koom ua ke zoo ntawm Changling Gas Field thiab Daqingzijing Oilfield, Jilin Oilfield tau ua qhov kev sim sim ntawm CCUS-EGR thiab CCUS-EOR synergistically txhim kho kev rov qab los.
Cov cheeb tsam ib puag ncig muaj ob qhov loj loj: helium muab rau cov pa roj carbon dioxide siab thiab Jilin Petrochemical Pipeline. Tom qab cov pa roj carbon dioxide raug txhaj rau hauv qis Yingcheng Formation los txhim kho tus nqi rov qab ntawm cov roj reservoirs, cov roj uas tsim tawm tau muab cais tawm thiab tom qab ntawd txhaj rau hauv Daqingzi Oilfield sab saud txhawm rau txhim kho tus nqi rov qab ntawm cov roj av. Tom qab cov pa roj carbon dioxide reservoir yog mined, cov roj cia tuaj yeem rov tsim kho kom ua tiav cov pa roj carbon monoxide rov ua dua thiab xoom emission. Ua kom muaj txiaj ntsig zoo ntawm cov khoom siv roj av, kev teeb tsa hauv av, cov kav dej hauv av, chaw nres tsheb, thiab lwm yam, kev ua qauv qhia peb sab ntawm helium efficiency + roj thiab roj synergistically txhim kho kev rov qab + roj cia yog tsim. Nws tau kwv yees tias tus nqi rov qab tuaj yeem nce ntxiv los ntawm ntau dua 10% los ntawm kev txhaj tshuaj roj kom tshem tawm Changling volcanic gas reservoir, uas yuav pab ua kom tiav cov khoom lag luam ruaj khov ntawm Songnan natural gas thiab qhib txoj hauv kev tshiab rau cov roj qub qub kom ua tiav qib siab. kev txhim kho efficiency.
Nws tau nkag siab tias Tuam Tshoj National Petroleum Corporation tau tsim ib pab pawg tshawb fawb ntawm Jilin Oilfield Exploration thiab Development Research Institute. Raws li kev sim ua haujlwm rau thawj qhov kev sim hauv tebchaws CCUS-EGR hauv cov roj hluav taws xob hluav taws xob, cov txiaj ntsig kev tshawb fawb tuaj yeem sau qhov sib txawv hauv hom kev tshawb fawb no. Los ntawm kev tshawb fawb thev naus laus zis thiab kev tsim kho thiab kev tshawb fawb, nws tuaj yeem tsim kho tshiab CCUS-EGR thev naus laus zis series rau volcanic gas reservoirs, sib sau cov peev txheej, thiab txhawb nqa ntsuab, qis-carbon thiab kev loj hlob zoo.
