5200m ua! Kuv Lub Tebchaws Qhov Kev Tshawb Fawb Txog Geothermal Deepest Zoo Ua tiav
Apr 11, 2024
Lub Fushenre 1 zoo siv los ntawm Sinopec hauv Hainan tau ua tiav qhov tob ntawm 5,200 meters, teeb tsa cov ntaub ntawv tshiab rau qhov tob tshaj plaws hauv kev tshawb fawb hauv av hauv kuv lub tebchaws. Qhov kev vam meej ntawm qhov dej no tau qhia txog kev tsim thiab kev txhim kho cov txheej txheem ntawm kev sib sib zog nqus geothermal hauv South Tuam Tshoj, uas txhais tau hais tias kuv lub teb chaws tau ua kev tawg tshiab hauv kub qhuav pob zeb tshawb nrhiav hauv thaj av thiab qhov tob. Nws yuav pab txhim kho txoj kev loj hlob loj thiab kev siv cov khoom siv hluav taws xob nyob rau sab qab teb Tuam Tshoj thiab pab kho cov qauv hluav taws xob hauv cheeb tsam. ntawm qhov tseem ceeb heev.
Zoo Fushenre 1 yog ib qho tseem ceeb ntawm kev tshawb nrhiav hauv qhov chaw zoo tshaj plaws los ntawm Sinopec Petroleum Exploration thiab Development Research Institute. Lub hom phiaj drilling yog granite 250 lab xyoo dhau los. Nws yog ib tug tob qhuav kub pob zeb geothermal zoo. Txij li thaum drilling pib thaum Lub Yim Hli 2023, lub qhov dej tau siv ntau cov thev naus laus zis tshiab ntawm nws tus kheej tsim los ntawm Sinopec xws li "dual-drive drilling + high-pressure txhaj". Qhov kub ntawm ze li ntawm 3,900 meters siab tshaj 150 degree, ncav cuag high-temperature geothermal qauv. Ntawm qhov kub ntawm 5,{11}} meters Nws siab tshaj 180 degree thiab mus txog qhov kub qhuav pob zeb kub txwv tau teev tseg hauv cov qauv kev lag luam hauv lub teb chaws. Nws tau tsim cov thev naus laus zis tseem ceeb rau kev tshawb nrhiav qhov tob hauv geothermal thiab kev ntsuam xyuas thiab ua tiav cov hom phiaj xav tau thiab lub hom phiaj xav tau ntawm cov dej tshawb fawb tshawb fawb.
Hauv cov kauj ruam tom ntej, Sinopec yuav ua qhov kev tshawb fawb tob thiab kev sim teb raws li Well Fushenre 1, tsim thawj qhov sib sib zog nqus ntawm cov khoom siv hluav taws xob hauv tsev kawm qib siab-kev tshawb fawb kev sib koom ua ke kev tshawb fawb kev tshawb fawb platform thiab kev txhim kho thiab kev siv ua qauv qhia hauv South China, thiab tshawb nrhiav thiab daim ntawv theoretical txoj kev thiab txoj kev haum rau South Tuam Tshoj. Cov txheej txheem thev naus laus zis pab kuv lub tebchaws ua tiav nws lub hom phiaj "ob chav carbon".
Kev txhim kho thiab kev siv cov peev txheej geothermal hauv kuv lub teb chaws feem ntau yog nyob ntawm qhov ntiav thiab nruab nrab-dav hydrothermal geothermal peev txheej. Txawm li cas los xij, kev txhim kho ntawm cov peev txheej hauv qab dej kub hauv qab 3, 000 meters, tshwj xeeb tshaj yog cov pob zeb qhuav kub, tseem nyob rau theem tshawb nrhiav. Cov pob zeb kub qhuav feem ntau yog hais txog cov pob zeb kub kub faus ntau txhiab meters hauv av nrog qhov kub siab tshaj 180 degree thiab tsis muaj dej los yog tsuas yog me me ntawm cov dej hauv. Raws li Tuam Tshoj Geological Survey, tus nqi ntawm cov pob zeb kub qhuav hauv qhov chaw sov li ntawm 3 mais mus rau 10,000 meters hauv av hauv kuv lub teb chaws thaj av yog sib npaug rau 856 trillion tons ntawm cov qauv thee. Txawm tias tsuas yog 2% raug rho tawm, nws tuaj yeem ncav cuag kuv lub teb chaws txhua xyoo kev tsim khoom hauv 2023. 2993 npaug ntawm kev siv lub zog.
Tam sim no, Sinopec txuas ntxiv delve rau hauv thaj chaw ntawm geothermal zog thiab tau dhau los ua qhov loj tshaj plaws geothermal zog txhim kho thiab siv kev lag luam hauv Suav teb. Nyob rau hauv cov nqe lus ntawm kev tshawb nrhiav qhov loj-scale kev loj hlob ntawm geothermal zog, Sinopec tau ua ib tug geothermal cua sov muaj peev xwm ntawm ze li ntawm 100 lab square meters thiab tsim ntau lub regional geothermal cua sov tej yaam num nrog ib tug scale ntawm lab lab square meters. Ntawm lawv, qhov project cua kub cua sov tsim hauv Xiongan New Area tau lees paub los ntawm cov zej zog thoob ntiaj teb. Lub Chaw Haujlwm Saib Xyuas Hluav Taws Xob Hluav Taws Xob tau suav nrog hauv cov npe ntawm cov haujlwm txhawb nqa thoob ntiaj teb; Raws li kev txhawb nqa kev tshawb fawb thiab thev naus laus zis hauv kev lag luam geothermal, nws tau tsim kho tshiab tsim ob txoj kev xav ntawm geothermal system tsim mechanism thiab thermal cia thiab hloov hluav taws xob mechanism, thiab tau kov yeej ntau cov thev naus laus zis xws li "ua cua sov yam tsis siv dej" . Cov thev naus laus zis tseem ceeb; Nyob rau hauv cov nqe lus ntawm kev pab rau txoj kev loj hlob ntawm lub teb chaws geothermal kev lag luam, Sinopec kuj coj tus thawj coj nyob rau hauv kev sau ntau tshaj 50% ntawm kev lag luam qauv thiab kuv lub teb chaws tus thawj International Geothermal Association tus qauv nyob rau hauv lub ntiaj teb no geothermal teb, thiab ntse tuav lub 2023 World Geothermal Congress.
