Ngomhla zingama-26 kuSepthemba, 2025, i-Daqing Oilfield yamemezela impumelelo ebalulekile: I-Gulong Continental Shale Oil National Demonstration Zone iqinisekise ukwengezwa kwamathani ayizigidi eziyi-158 ezigciniwe ezifakazelwe. Le mpumelelo inikeza ukwesekwa okubalulekile ekuthuthukisweni kwemithombo kawoyela we-shale yezwekazi laseShayina.
I-Daqing Gulong Continental Shale Oil National Demonstration Zone itholakala enyakatho yeSongliao Basin, ngaphakathi kweDorbod Mongolian Autonomous County, Daqing City, Province of Heilongjiang. Ihlanganisa indawo engamakhilomitha-skwele ayi-2,778. Le phrojekthi ithole ukweqa okusheshayo isuka “ezindaweni ezigciniwe eziqinisekisiwe” iye “entuthukweni ephumelelayo,” ngomphumela wansuku zonke manje ongaphezu kwamathani ayi-3,500.
Ukusungulwa kweGulong Continental Shale Oil National Demonstration Zone yi-Daqing Oilfield kwaqala ngo-2021. Ngonyaka olandelayo, le ndawo yangena esigabeni sayo sokuqala sokukhiqiza isilingo esikhulu, ithela cishe amathani ayi-100,000 oluhlaza. Ngo-2024, ukukhiqizwa konyaka kwase kudlule amathani angu-400,000, sekuphindeke kabili iminyaka emithathu ilandelana—okuyinkomba ecacile yokukhula kwayo kwe-leapfrog. Kuze kube manje, indawo yokubonisa isibhole isamba semithombo evundlile engama-398 enomphumela ophelele ongaphezu kwamathani ayizigidi eziyi-1.4.
Lezi zingosi ezisanda kwengezwa ezifakazelwe zizosebenza njengomgogodla wokwesekwa kokusungulwa kwendawo yokubonisa kazwelonke engamathani ayisigidi ngo-2025. Khonamanjalo, ukukhiqizwa kukawoyela we-shale we-CNPC kulindeleke ukuthi kudlule amathani ayizigidi eziyisi-6.8 kulo nyaka.
I-Shale iyidwala le-sedimentary elihlukaniswa ngesakhiwo salo esine-laminated, esifana neshidi. Amafutha e-shale aqukethwe ngaphakathi kwe-matrix yawo ahlanganisa insiza ye-petroleum okukhulunywa ngayo. Ngokungafani nama-hydrocarbons avamile, ukukhishwa kukawoyela we-shale kwenza kudingeke ukuthi kusetshenziswe ubuchwepheshe be-hydraulic fracturing. Lokhu kuhilela umjovo onengcindezi ephezulu yoketshezi olwakhiwe ngamanzi kanye nama-propants ukuze ahehe futhi anwebe ukuphuka ekwakhekeni kwe-shale, ngaleyo ndlela kube lula ukugeleza kukawoyela.
Ukusatshalaliswa kukawoyela we-shale emhlabeni wonke kuhlanganisa imicengezi engama-75 emazweni angama-21, kanti isamba sezinsiza ezitholakala ngokobuchwepheshe silinganiselwa kumathani ayizigidigidi ezingama-70. I-China inomthombo wensiza ehlukile kulesi sizinda, nowoyela wayo we-shale otholakala ezitsheni ezinhlanu ezinkulu ze-sedimentary, okuhlanganisa i-Ordos ne-Songliao. Izwe selithuthukele ekubeni sezingeni eliphezulu emhlabeni wonke ngokobucwepheshe bokumba kanye nezinga lemali yalo egcinelwe ukubuyiswa.
Kumane kwaqondana okuphawulekayo ukuthi le mpumelelo iza ngosuku olufanayo—u-September 26—lapho, eminyakeni engu-66 edlule, lapho kuzalwa khona iDaqing Oilfield ngokwayo. Ngalolo suku ngo-1959, i-Songji-3 yathinta kahle uwoyela wezohwebo, umcimbi owasula ilebula "yezwe elimpofu uwoyela" e-China unomphela futhi wavula isahluko esisha esihle emlandweni wezwe we-petroleum.
I-Shale Gas Desanding ichazwa ngokuthi ukususwa okungokoqobo/ngokwemishini kokungcola okuqinile (isb., isihlabathi sokwakheka, isihlabathi esine-frac/i-propant, ukusikwa kwamadwala) kusukela kumfudlana wegesi ye-shale egcwele amanzi ngesikhathi sokukhiqiza. Lokhu okuqinile kwethulwa kakhulu ngesikhathi sokusebenza kwe-hydraulic fracturing. Ukwehlukana okunganele noma ukubambezeleka kungaholela kulokhu:
Ukulimala Kwe-Abrasive:Ukuguga okusheshisiwe kwamapayipi, ama-valve, nama-compressor.
Izinkinga Zokuqinisekisa Ukugeleza:Ukuvinjwa kwamapayipi aphansi.
Ukuhluleka Kwezinsimbi:Ukuvala imigqa yokucindezela kwensimbi.
Izingozi Zokuphepha:Ukwanda kwengozi yezigameko zokuphepha komkhiqizo.
I-SJPEE Shale Gas Desander iletha ukusebenza okuphezulu ngokuhlukaniswa okunembayo, ifinyelela izinga lokususwa elingu-98% lezinhlayiya eziyi-10-micron. Amandla ayo aqinisekiswa izitifiketi ezigunyaziwe, okuhlanganisa amazinga e-ISO akhishwe yi-DNV/GL kanye nokuthobela ukugqwala kwe-NACE. Iklanyelwe ukuqina okuphezulu, iyunithi ifaka izinto zangaphakathi ze-ceramic ezingagugi ezinomklamo ovimbela ukuvala. Idizayinelwe ukusebenza kalula, iqinisekisa ukufakwa kalula, ukugcinwa okulula, kanye nempilo yesevisi eyandisiwe, ihlinzeka ngesixazululo esilungile sokukhiqiza okuthembekile kwegesi ye-shale.
Siqhubeka nokuphusha imingcele yedizayini ye-desander, silwela ukusebenza kahle okuphezulu, indawo encane, kanye nezindleko eziphansi eziphelele—konke lokhu sivula ubuchwepheshe obuluhlaza bemboni esimeme.
Sihlinzeka ngohlu olubanzi lwezixazululo ze-desander eziklanyelwe izinselele ezihlukahlukene. Kusukela ku-Wellhead kanye ne-Natural Gas Desander kuya kumamodeli akhethekile we-High-Efficiency Cyclone kanye ne-Ceramic-Lined yezinsiza zokujova emanzini noma emanzini, imikhiqizo yethu iletha ukusebenza okuthembekile kuzo zonke izinhlelo zokusebenza eziningi.
Kufakazelwe ezindaweni ezidinga kakhulu emhlabeni—kusuka ezindaweni ezingasogwini ze-CNOOC kanye neGulf of Thailand kuya emisebenzini eyinkimbinkimbi ye-Petronas—ama-SJPEE desanders ayisixazululo esithenjwayo kuma-wellhead nasezinkundleni zokukhiqiza emhlabeni wonke. Baphatha kahle ukukhishwa kwezinto eziqinile kugesi, uketshezi oluphuma emthonjeni, amanzi akhiqiziwe, namanzi olwandle, kuyilapho bevumela umjovo wamanzi nezinhlelo zezikhukhula ukuthuthukisa ukukhiqizwa. Lolu hlelo lokusebenza oluphambili luqinise isithunzi somhlaba wonke se-SJPEE njengamandla amasha okulawula izinto eziqinile. Ukuzinikela kwethu okungaguquki ukuvikela izinto ozithakaselayo kanye nokwenza indlela eya empumelelweni eyabiwe.
