Qhov no compressor hloov carbon dioxide los ntawm khib nyiab mus rau cov khoom muaj nqis
Hauv peb cov kev nkag siab ib txwm muaj, carbon dioxide yog cov khoom siv khib nyiab, tab sis hauv kev lag luam roj, cov pa roj carbon dioxide tuaj yeem hloov mus ua "khoom siv" rau hauv cov khoom muaj nqis. Yuav ua li cas, koj yuav xav paub, puas carbon dioxide yuav tsum tau ua nrog drilling rau roj?
Roj muaj nyob rau hauv lub pores ntawm pob zeb thiab yog muab rho tawm los ntawm lawv. Feem ntau, thaum tshem cov roj, dej yog txhaj rau hauv qhov tsim kom nyem cov roj tawm ntawm qhov pores. Tab sis nyob rau hauv ib co low-permeability reservoirs, lub pores yog me me heev thiab yuav tsum tau tsis tshua muaj siab siab mus txhaj dej, ua rau extraction nyuaj. Supercritical carbon dioxide (carbon dioxide mus txog cov kua thaum nws tshaj nws qhov tseem ceeb nyob rau hauv high-pressure tej yam kev mob) muaj ib tug qis viscosity tshaj dej thiab yog yooj yim rau laum rau hauv pores. Thaum ntsib cov txheej txheem roj tsawg-permeability, nws tuaj yeem qhia tau nws cov kev txawj ntse, uas yog tam sim no tsim cov roj carbon dioxide roj rov qab technology sai.
Txawm li cas los xij, kev nyuaj ntawm cov cuab yeej tseem ceeb supercritical carbon dioxide compressor yog qhov siab heev, thiab cov teb chaws txawv teb chaws yeej ib txwm monopolized txog cov thev naus laus zis tseem ceeb. Txhawm rau ua kom muaj qhov sib txawv hauv tsev thiab ua tiav cov cuab yeej kev ntseeg siab thiab kev txhim kho tus kheej, Jichai Chengdu Compressor ceg tau ua haujlwm tsis tu ncua kev tshawb fawb txog qhov project txij li xyoo 2015. Los ntawm kev sib pauv nrog cov tuam txhab hauv tsev thiab txawv teb chaws, qhia txog sled technology, ua qhov kev tshawb fawb tob. ntawm cov khoom lag luam paub tab, thiab nce cov kev tshawb fawb tshiab hauv cov khoom tsim thiab kev tsim khoom, nws tau kov yeej cov kev nyuaj ntawm cov pa roj carbon dioxide compressors thiab paub txog cov thev naus laus zis tseem ceeb hauv chav tsim khoom tsim thiab tsim khoom. Thaum lub Kaum Ib Hlis 2018, thawj tiam CO2 supercritical txhaj tshuaj compressor chav tsev ntawm Jichai tau thov hauv Fushan Oilfield hauv Hainan.
Jichai CCUS CO2 Supercritical Injection Compressor Unit tiav thiab offline
Jichai tseem tsom mus rau CCUS tag nrho kev lag luam saw carbon dioxide compressor thev naus laus zis, thiab los ntawm 2021, koom nrog kev tshawb fawb thiab thev naus laus zis tshwj xeeb ntawm Tuam Tshoj Petroleum Group, "Tsev Kawm Ntawv Tseem Ceeb thiab Ua Yeeb Yam ntawm Carbon Dioxide Scale Capture, Roj Tshem Tawm thiab faus puv. Kev lag luam Chain". Kev cia siab rau Jilin Oilfield CCUS-EOR lab tuj kev ua qauv qhia, kev ntsuas cov khoom lag luam thiab cov kev xav tau ntawm kev lag luam, Jichai Compressor Ceg tau txuas ntxiv nws cov kev tshawb fawb thiab kev tsim kho kom ua tiav lub cim thib ob CCUS carbon dioxide supercritical txhaj tshuaj compressor chav tsev khoom, mastering tus tsim thiab tsim technology. ntawm 50 megapascals siab siab thiab 4500 kilowatts high-power CCUS carbon dioxide supercritical txhaj compressor units.
Tom qab pab pawg ua haujlwm tsis tu ncua hnub thiab hmo ntuj, thaum lub Plaub Hlis 19th ntawm lub xyoo no, Jichai ua tiav kev txhim kho thawj thib ob tiam CCUS carbon dioxide supercritical txhaj tshuaj compressor khoom - 28 megapascals high-pressure carbon dioxide supercritical txhaj compressor chav tsev, thiab xa nws mus rau qhov chaw thov hauv Jilin Oilfield. Qhov no yog qhov tseem ceeb ntawm kev tshawb fawb thiab kev loj hlob ntawm cov pa roj carbon dioxide compressors thoob plaws tag nrho cov kev lag luam saw ntawm Jichai.
Lub tsev tam sim no tab tom ua haujlwm 1000 teev ntawm kev ntsuas kev lag luam, nrog lub siab nkag ntawm 1.96 megapascals thiab lub siab tso tawm ntawm 20.9 megapascals. Nws txhaj 105000 tus qauv cubic meters roj ib hnub, thiab cov cuab yeej siv tau zoo. Kev lees txais qhov project tsuas yog nyob ib ncig ntawm lub ces kaum. Tom qab kev tsim khoom loj thiab siv cov khoom lag luam, CCUS supercritical carbon dioxide txhaj tshuaj compressor chav tsev thib ob yuav tsum ua tiav kev hloov pauv hauv tsev rau cov khoom lag luam zoo sib xws.
