Musi waGunyana 26, 2025, iyo Daqing Oilfield yakazivisa chiitiko chakakosha: iyo Gulong Continental Shale Oiri National Demonstration Zone yakasimbisa kuwedzera kwe158 miriyoni matani ematura akasimbiswa. Kubudirira uku kunopa tsigiro yakakosha mukusimudzirwa kweChina continental shale oiri zviwanikwa.
Iyo Daqing Gulong Continental Shale Oiri National Demonstration Zone iri kuchamhembe kweSongliao Basin, mukati meDorbod Mongolian Autonomous County, Daqing City, Heilongjiang Province. Inotenderera nzvimbo yese ye2,778 square kilometres. Iyo purojekiti yakawana kukurumidza kusvetuka kubva ku "kuchengeterwa kwakasimbiswa" kuenda ku "budiriro inobudirira," ine zuva nezuva kubuda zvino kudarika 3,500 matani.
Kugadzwa kweGulong Continental Shale Oil National Demonstration Zone neDaqing Oilfield kwakatanga muna 2021. Gore rakatevera, nzvimbo iyi yakapinda muchikamu chayo chekutanga chekuedza kukuru, ichipa matani angangoita 100,000 ehutsvina. Pakazosvika 2024, kugadzirwa kwepagore kwakange kwapfuura 400,000 matani, zvakapetwa kaviri kwemakore matatu akateedzana-chiratidzo chakajeka chekukura kwayo kwe leapfrog. Kusvika pari zvino, nzvimbo yekuratidzira yakachera matsime mazana matatu nemakumi mapfumbamwe ane masere ane goho rinopfuura matani miriyoni imwe nemazana mana.
Iyi nzvimbo ichangobva kuwedzerwa inotsigirwa ichashanda senheyo yekutsigira kwekutanga miriyoni-matani yenyika yekuratidzira panosvika 2025. Zvichakadaro, CNPC's shale oil kubuda kunofungidzirwa kudarika 6.8 miriyoni matani gore rino.
Shale idombo re sedimentary rinosiyaniswa neyakaomesesa laminated, sheet-like chimiro. Mafuta e shale ari mukati me matrix ayo anoumba petroleum sosi iri mubvunzo. Kusiyana nemahydrocarbon akajairwa, kubviswa kwemafuta e shale kunoda kushandiswa kwe hydraulic fracturing technology. Izvi zvinosanganisira jekiseni repamusoro-soro remvura inoumbwa nemvura uye mapuropu kuti ape uye awedzere kutsemuka mukuumbwa kwe shale, nokudaro kufambisa kuyerera kwemafuta.
Kugovewa kwepasi rose kwemafuta e shale kunosvika mabheseni makumi manomwe neshanu munyika makumi maviri nerimwe, aine zviwanikwa zvehunyanzvi zvinodzoreredzwa zvinofungidzirwa kusvika matani mabhiriyoni makumi manomwe. China ine yakasarudzika zviwanikwa munzvimbo ino, nemafuta ayo e shale ari mumabheseni makuru mashanu e sedimentary, anosanganisira Ordos neSongliao. Nyika yafambira mberi kusvika pachinzvimbo chepamberi pasirese maererano nehunyanzvi hwekubvisa tekinoroji uye nehukuru hwematura ayo anogona kudzoserwa.
Isaona inoshamisa kuti iyi budiriro inouya pazuva rimwe chetero—September 26—iro, makore 66 apfuura, rakapupurira kuberekwa kweDaqing Oilfield imene. Pazuva iro muna 1959, tsime reSongji-3 rakabaya mafuta ekutengesa, chiitiko chakadzima zita rekuti "nyika ine urombo hwemafuta" kubva kuChina zvachose uye yakavhura chitsauko chitsva munhoroondo yepetroleum yenyika.
Shale Gasi Desanding inotsanangurwa sekubvisa kwemuviri/mechini yetsvina yakasimba (semuenzaniso, jecha rekugadzira, jecha refrac/proppant, matombo ekucheka) kubva pamvura ine shale gasi rwizi panguva yekugadzirwa. Aya maoriki anounzwa zvakanyanya panguva yehydraulic fracturing operations. Kusakwana kana kunonoka kuparadzana kunogona kukonzera:
Abrasive Kukuvadza:Kuwedzera kupfeka kwepombi, mavharuvhu, uye compressors.
Flow Simbiso Matambudziko:Zvivharo mumapaipi akadzika-akadzika.
Kukundikana Kwezviridzwa:Kuvhara kwemitsetse yekumanikidza chiridzwa.
Safety Hazards:Kuwedzera njodzi yezviitiko zvekuchengetedza kugadzirwa.
Iyo SJPEE Shale Gasi Desander inopa kushanda kwepamusoro kuburikidza nekunyatso kupatsanurwa, kuwana 98% yekubvisa chiyero chegumi-micron zvimedu. Kugona kwayo kunosimbiswa nezvitupa zvine chiremera, zvinosanganisira DNV/GL-yakabudiswa ISO zviyero uye NACE corrosion kutevedzera. Yakagadzirirwa kusimba zvakanyanya, iyo unit inoratidzira kupfeka-inodzivirira ceramic yemukati ine anti-kuvhara dhizaini. Yakagadzirirwa kushanda isingaite, inovimbisa kuisirwa nyore, kugadzirisa kuri nyore, uye hupenyu hwesevhisi hwakawedzerwa, ichipa mhinduro yakakwana yeakavimbika shale gasi kugadzirwa.
Isu tinoramba tichisundidzira miganhu yedhizaini yedhizaini, tichivavarira kugona kwepamusoro, diki tsoka, uye yakaderera mutengo wakazara-sese tichipayona tekinoroji yakasvibirira yeindasitiri inoenderera.
Isu tinopa huwandu hwakakwana hwe desander mhinduro dzakagadzirirwa matambudziko akasiyana. Kubva kuWellhead uye Natural Gasi Desanders kune yakasarudzika Yakakwira-Kushanda Dutu uye Ceramic-Mutsetse modhi yematsime kana masevhisi ejekiseni remvura, zvigadzirwa zvedu zvinounza mashandiro akavimbika kune akawanda maapplication.
Yakaratidzwa munzvimbo dzinonyanya kudiwa pasirese-kubva kumahombekombe eCNOOC uye Gulf yeThailand kusvika kune yakaoma mashandiro ePetronas-SJPEE desanders ndiyo mhinduro yakavimbika pane zvakanaka uye mapuratifomu ekugadzira pasi rese. Ivo vanonyatsobata kubviswa kwakasimba mugasi, zvinwiwa zvemutsime, mvura inogadzirwa, uye mvura yegungwa, ukuwo vachigonesa jekiseni remvura nemafashama mapurogiramu kuwedzera kugadzirwa. Iyi inotungamira-kumucheto application yakasimbisa mukurumbira wepasirese weSJPEE sesimba rekuvandudza mukutonga kwakasimba. Kuzvipira kwedu kusingazungunuke kuchengetedza zvido zvako zvekushanda uye kugadzira nzira yekubudirira pamwe chete.
