▲Masamba Ofiira a Tsamba 16 Kufufuza ndi Malo Achitukuko
Pa Ogasiti 21, zikulengezedwa kuchokera ku ofesi yankhani ya Sinopec kuti Hongxing Shale Gas Field yoyendetsedwa ndi Sinopec Jianghan Oilfield idalandira chiphaso kuchokera ku Unduna wa Zachilengedwe chifukwa cha nkhokwe zake zotsimikizika zamafuta a shale a 165.025 biliyoni kiyubiki metres. Chochitika ichi ndi chizindikiro cha kukhazikitsidwa kovomerezeka kwa gawo lina lalikulu la gasi ku China, ndikuwonetsanso kuthekera kofunikira kwa dera la Hongxing. Kutukuka bwino kwa malo osungiramo gasi wa shale ndi njira yabwino yowonetsetsa kuti dziko lili ndi chitetezo champhamvu.
Zotsogola Zaukadaulo Zaukadaulo Zatsegulidwa "Makhodi Amphamvu" Apansi Pansi.
Ili m'chigawo cha Hubei ndi Chongqing Municipality, Hongxing Shale Gas Field imayang'ana mapangidwe a Permian pakuya kwa 3,300 mpaka 5,500 metres, omwe amadziwika ndi mapindikidwe ovuta komanso zovuta zowunikira komanso chitukuko. Sinopec Jianghan Oilfield yapitilizabe ukadaulo wotsogola pakuwomba gasi wosanjikiza wa shale pansi pazovuta, kupanga malingaliro owonjezera a gasi wa shale ndikupititsa patsogolo kuphatikiza kwaukadaulo wa geology. Pozindikira “malo abwino a geological-engineering dual sweet spots” kuti achulukitse mpweya wa shale, pulojekitiyi yachita upainiya woyamba ku China wa thililiyoni wa kiyubiki-mita wofufuza za shale mu njira yatsopano yopitilira nthawi ya Silurian.
Kuphatikiza apo, gulu lofufuzalo lidapanga ukadaulo waluso kuti mumalize bwino bwino ndikukondoweza kwapang'onopang'ono, kukulitsa kuyesa kwa chitsime chimodzi kuchokera pa ma kiyubiki metres 89,000 patsiku mpaka ma kiyubiki metres 323,500 patsiku.
▲ Malo Obowola Tsamba Lofiyira 24HF
Mkulu wina wa Jianghan Oilfield adati mu gawo lotsatira, Sinopec ipititsa patsogolo kufufuza ndi kuwunika kwachitukuko ndi kutumizidwa, kuzama kafukufuku wamakono ofunikira kuphatikizapo geology, njira zachitukuko, ndi njira zaumisiri, kukulitsa madera atsopano a kukula kwa gasi wa shale mu Wujiaping Formation, ndikulimbikitsa mwakhama kupanga maziko atsopano a magalasi akuluakulu.
▲ Atumizidwa: Malo oyeretsera gasi achilengedwe ku Western Hubei——Hongxing Purification
Sinopec yakhala ikuyendetsa mosalekeza chitukuko chapamwamba chamakampani opanga gasi ku China. Mbiri yazachuma ku China imadziwika ndi "malasha ochulukirapo, mafuta osowa, ndi gasi wosowa," zomwe zimapangitsa kuti mafuta ndi gasi azitenga kunja kwanthawi yayitali. Kufufuza ndi chitukuko cha gasi wa shale ndizofunikira kwambiri pakukula kwa mphamvu zaku China. Sinopec yanyamula mwachangu udindo wopezera chuma cha gasi mdziko muno. Chakumapeto kwa chaka cha 2012, kupezeka kwa Fuling Shale Gas Field kunali chiyambi cha chitukuko cha gasi wa shale ku China, ndikuyika dzikolo kukhala lachitatu pambuyo pa United States ndi Canada kuti likwaniritse malonda a gasi wa shale.
Mu 2017, Sinopec adamaliza ntchito yomanga gawo loyamba la gasi la shale ku China lomwe limakwana ma cubic metres 10 biliyoni pachaka - Fuling Shale Gas Field. Mu 2020, gawo loyamba la Weirong Shale Gas Field lidamalizidwa, kukhala malo oyamba amafuta aku China ku China okhala ndi nkhokwe zotsimikizika zopitilira ma kiyubiki mita 100 biliyoni. Mu 2024, zitsime zofufuzira monga Jinye 3 ndi Ziyang 2 ku Sichuan Basin zidatsegula mwayi watsopano wokulitsa nkhokwe ndi kukula kwa kupanga.
Mpaka pano, Sinopec yakhazikitsa malo okwana thililiyoni-cubic-mita-scale gasi wa shale (Fuling) ndi malo anayi akuya a gasi omwe ali ndi nkhokwe zopitilira ma kiyubiki mita mabiliyoni 100 (Weirong, Qijiang, Yongchuan, ndi Hongxing), mosalekeza kulowetsa mphamvu zoyera mu chitukuko chapamwamba.
Kupanga gasi wa shale kumafuna zida zofunikira zochotsera mchenga monga ma desanders.
Kuchotsa mpweya wa shale kumatanthawuza njira yochotsera zodetsa zolimba monga njere zamchenga, mchenga wophwanyika (proppant), ndi zidutswa za miyala kuchokera ku mitsinje ya mpweya wa shale (ndi madzi olowetsedwa) kudzera munjira zakuthupi kapena zamakina panthawi yochotsa ndi kupanga gasi wa shale.
Monga mpweya wa shale umapezeka makamaka kudzera muukadaulo wa hydraulic fracturing (kuchotsa fracturing), madzi obweranso amakhala ndi njere zambiri zamchenga kuchokera pamapangidwe ndi zotsalira zotsalira za ceramic particles kuchokera ku fracturing operations. Ngati tinthu tating'ono ting'onoting'ono sitinasiyanitsidwe koyambirira kwa njira, zingayambitse kukokoloka kwa mapaipi, mavavu, ma compressor ndi zida zina, kapena kuyambitsa kutsekeka kwa mapaipi m'zigawo zotsika, kutsekeka kwa mapaipi owongolera zida, kapena kuyambitsa zochitika zachitetezo.
SJPEE's shale gas desander imagwira ntchito mwapadera kwambiri ndi kuthekera kwake kolekanitsa (98% kuchotsa tinthu ting'onoting'ono ta 10-micron), ziphaso zovomerezeka (chitsimikizo cha ISO cha DNV/GL choperekedwa ndi NACE anti-corrosion compliance), komanso kulimba kwanthawi yayitali (yokhala ndi kapangidwe kake ka anti-logging). Amapangidwa kuti azigwira ntchito molimbika, amapereka kuyika kosavuta, kugwira ntchito kosavuta ndi kukonza, komanso moyo wautali wautumiki - kupangitsa kuti ikhale yankho labwino kwambiri pakupangira gasi wodalirika wa shale.
Kampani yathu ikudzipereka mosalekeza kupanga ma desander ogwira ntchito bwino, ocheperako, komanso otsika mtengo pomwe tikuyang'ananso zatsopano zomwe zimagwirizana ndi chilengedwe.
Ma desanders athu amabwera m'mitundu yosiyanasiyana ndipo ali ndi ntchito zambiri. Kuphatikiza pa ma gasi a shale, monga Cyclone Desander, Wellhead Desander, Cyclonic Well stream crude Desander With Ceramic Liners, Desander jakisoni wamadzi, Gesi Wachilengedwe Desander, etc.
Ma desanders a SJPEE akhala akugwiritsidwa ntchito pamapulatifomu opangira bwino komanso malo opangira gasi ndi mafuta monga CNOOC, PetroChina, Malaysia Petronas, Indonesia, Gulf of Thailand, ndi ena. Amagwiritsidwa ntchito pochotsa zolimba mu gasi kapena madzimadzi amchere kapena madzi opangidwa, komanso kuchotsa madzi a m'nyanja olimba kapena kubwezeretsanso kupanga. Jakisoni wamadzi ndi kusefukira kwamadzi kuti muwonjezere kupanga ndi zochitika zina.
Pulatifomu yayikuluyi yayika SJPEE ngati njira yodziwika padziko lonse lapansi pakuwongolera ndiukadaulo wowongolera. Nthawi zonse timaika patsogolo zofuna za makasitomala athu ndikuchita nawo chitukuko limodzi.
