Pa Seputembara 26, 2025, Daqing Oilfield idalengeza za kupambana kwakukulu: Gulong Continental Shale Oil National Demonstration Zone idatsimikizira kuwonjezera kwa matani 158 miliyoni a malo otsimikiziridwa. Kupindula uku kumapereka chithandizo chofunikira pa chitukuko cha mafuta a shale ku China.
Daqing Gulong Continental Shale Oil National Demonstration Zone ili kumpoto kwa Songliao Basin, mkati mwa Dorbod Mongolian Autonomous County, Daqing City, Province la Heilongjiang. Ndi malo okwana 2,778 masikweya kilomita. Pulojekitiyi yakwanitsa kudumpha mwachangu kuchokera ku "zosungirako zotsimikiziridwa" kupita ku "chitukuko chogwira ntchito," zomwe zimatuluka tsiku ndi tsiku tsopano zopitirira matani 3,500.
Kukhazikitsidwa kwa Gulong Continental Shale Oil National Demonstration Zone ndi Daqing Oilfield kunayamba mu 2021. Chaka chotsatira, chigawochi chinalowa mu gawo lake loyamba la kuyesa kwakukulu, kutulutsa pafupifupi matani 100,000 a crude. Pofika 2024, kupanga kwapachaka kunali kopitilira matani 400,000, kuwirikiza kawiri kwa zaka zitatu zotsatizana —chizindikiro chodziwikiratu cha kukula kwake kwa leapfrog. Mpaka pano, malo owonetserako adakumba zitsime zonse zopingasa 398 zomwe zidachulukira kupitilira matani 1.4 miliyoni.
Malo otetezedwa omwe angowonjezeredwa kumenewa adzakhala ngati gwero lothandizira kukhazikitsa malo owonetsera dziko la matani miliyoni pofika chaka cha 2025. Pakalipano, mafuta a shale a CNPC akuyembekezeka kupitirira matani 6.8 miliyoni chaka chino.
Shale ndi thanthwe la sedimentary losiyanitsidwa ndi kapangidwe kake kakang'ono ka laminated, ngati pepala. Mafuta a shale omwe ali mkati mwa matrix ake amapanga mafuta a petroleum omwe akufunsidwa. Mosiyana ndi ma hydrocarbons wamba, kuchotsa mafuta a shale kumafuna kugwiritsa ntchito ukadaulo wa hydraulic fracturing. Izi zimaphatikizapo jekeseni wothamanga kwambiri wamadzimadzi opangidwa ndi madzi ndi zowonjezera kuti apangitse ndi kukulitsa fractures mu mapangidwe a shale, motero kumathandizira kutuluka kwa mafuta.
Kugawidwa kwamafuta a shale padziko lonse lapansi kumadutsa mabeseni 75 m'maiko 21, ndi zinthu zomwe zitha kubwezeredwa mwaukadaulo pafupifupi matani 70 biliyoni. China ili ndi mwayi wapadera wopezeka m'derali, mafuta ake a shale omwe ali m'mabeseni akuluakulu asanu, kuphatikiza Ordos ndi Songliao. Dzikoli lapita patsogolo kwambiri padziko lonse lapansi malinga ndi luso lazotulutsa komanso kukula kwa nkhokwe zomwe zingabwezedwe.
N’zochititsa chidwi kuti chipambano chimenechi chikufika pa deti lomwelo—September 26—limene, zaka 66 zapitazo, anaona kubadwa kwa Daqing Oilfield. Patsiku limenelo mu 1959, chitsime cha Songji-3 chinakhudza mafuta amalonda, chochitika chomwe chinachotsa chizindikiro cha "dziko losauka kwa mafuta" ku China kwamuyaya ndikutsegula mutu watsopano wabwino kwambiri m'mbiri ya mafuta a dziko.
Kuchotsa gasi ku Shale kumatanthauzidwa ngati kuchotsa zonyansa zolimba zakuthupi/makina (mwachitsanzo, mchenga wopangidwa, mchenga wa frac/proppant, zidutswa za miyala) kuchokera mumtsinje wodzaza ndi madzi a shale panthawi yopanga. Zolimba izi zimayambitsidwa kwambiri panthawi ya hydraulic fracturing. Kulekanitsa kosakwanira kapena kuchedwa kungayambitse:
Kuwonongeka kwa Abrasive:Kuthamanga kwachangu kwa mapaipi, ma valve, ndi compressor.
Nkhani Zotsimikizira Kuyenda:Zotsekera m'mapaipi otsika.
Kulephera kwa Chida:Kutsekeka kwa mizere yokakamiza zida.
Zowopsa Zachitetezo:Chiwopsezo chowonjezereka cha zochitika zachitetezo chopanga.
SJPEE Shale Gas Desander imapereka magwiridwe antchito apamwamba kudzera pakulekanitsa kolondola, kukwaniritsa 98% kuchotsera kwa tinthu tating'ono ta 10-micron. Kuthekera kwake kumatsimikiziridwa ndi ziphaso zovomerezeka, kuphatikiza miyezo ya ISO yoperekedwa ndi DNV/GL ndi kutsata kwa dzimbiri kwa NACE. Chopangidwira kuti chikhale cholimba kwambiri, chipangizocho chimakhala ndi zida za ceramic zosagwira ntchito zokhala ndi anti-clogging. Zapangidwira kuti zigwire ntchito movutikira, zimatsimikizira kuyika kosavuta, kukonza kosavuta, komanso moyo wautali wautumiki, zomwe zimapereka njira yabwino kwambiri yopangira gasi wodalirika wa shale.
Timakankhira mosalekeza malire a mapangidwe a desander, kuyesetsa kuchita bwino kwambiri, kutsika pang'ono, ndi kutsika mtengo wonse - zonsezi tikuchita upangiri waukadaulo wobiriwira wamakampani okhazikika.
Timapereka mayankho athunthu a desander opangidwira zovuta zosiyanasiyana. Kuchokera ku Wellhead ndi Natural Gas Desanders kupita kumitundu yapadera ya Cyclone Yogwira Ntchito Kwambiri ndi Ceramic-Lined pamayendedwe amadzi kapena jekeseni wamadzi, zinthu zathu zimapereka magwiridwe antchito odalirika pamapulogalamu angapo.
Kutsimikiziridwa m'malo ovuta kwambiri padziko lonse lapansi - kuchokera kumadera akunyanja a CNOOC ndi Gulf of Thailand kupita ku zovuta za Petronas - SJPEE desanders ndiye yankho lodalirika pamapulatifomu opangira zinthu padziko lonse lapansi. Amagwira bwino ntchito yochotsa zolimba mu gasi, madzi amchere, madzi opangidwa, ndi madzi a m'nyanja, komanso amathandizira jekeseni wamadzi ndi mapulogalamu osefukira kuti apititse patsogolo kupanga. Ntchito yotsogola iyi yalimbitsa mbiri ya SJPEE padziko lonse lapansi ngati mphamvu yowongolera zinthu zolimba. Kudzipereka kwathu kosasunthika ndikuteteza zokonda zanu ndikupanga njira yopezera chipambano chogawana.
