China ipeza malo enanso okulirapo gasi okhala ndi ma cubic metres 100 biliyoni!

Pa Ogasiti 14, malinga ndi ofesi ya nyuzipepala ya Sinopec, kupambana kwina kwakukulu kunachitika mu ntchito ya "Deep Earth Engineering · Sichuan-Chongqing Natural Gas Base". Southwest Petroleum Bureau of Sinopec idapereka malo otetezedwa kumene a Yongchuan Shale Gas Field a 124.588 biliyoni cubic metres, omwe adavomerezedwa ndi gulu la akatswiri ochokera ku Unduna wa Zachilengedwe. Izi zikuwonetsa kubadwa kwa gawo lina lalikulu, lakuya, komanso lophatikizika la gasi la shale ku China lomwe lili ndi nkhokwe zopitilira ma kiyubiki metres 100 biliyoni, zomwe zimapereka chithandizo champhamvu pa Sichuan-Chongqing 100-biliyoni-cubic-mita zopangira mphamvu. Zithandizanso kuti pakhale mphamvu zopangira mphamvu zopangira mtsinje wa Yangtze Economic Belt.

Malo a Gasi a Yongchuan Shale, omwe amadziwika kuti ndi mosungiramo mpweya wa shale, ali m'boma la Yongchuan, Chongqing, mkati mwa chigawo chakum'mwera kwa Sichuan Basin. Mapangidwe akuluakulu okhala ndi mpweya amakhala mozama mopitilira 3,500 metres.

Mu 2016, kuwunikira kwakukulu kunakwaniritsidwa pomwe Well Yongye 1HF, kuwunika koyamba komwe kunatumizidwa ndi Sinopec Southwest Petroleum Bureau m'derali, kudapeza bwino Malo a Gasi a Yongchuan Shale. Pofika chaka cha 2019, ma cubic metres owonjezera 23.453 biliyoni a malo otsimikiziridwa a geological reserve adatsimikiziridwa ndi gulu la akatswiri ochokera ku Unduna wa Zachilengedwe.

Pambuyo pake, Sinopec idakulitsa ntchito zowunikira mdera lapakati-kumpoto la Yongchuan, ndikuthana ndi zovuta zaukadaulo. Izi zinafika pachimake pa chiphaso chathunthu cha Yongchuan Shale Gas Field, yokhala ndi nkhokwe zotsimikizika za geological zomwe zidafika pa 148.041 biliyoni kiyubiki metres.

Technologies Zatsopano Zimapangitsa Gasi Wakuya wa Shale "Kuwoneka" ndi "Kupezeka"

Gulu lofufuzalo linasonkhanitsa deta yolondola kwambiri ya 3D ya seismic pa gasi wakuya wa shale ndipo inachititsa maulendo angapo ophatikizana a maphunziro a geological-geophysical-engineering. Anapanga matekinoloje apamwamba, kuphatikizapo njira zatsopano zopangira mapu ndi njira zamakono zowonetsera, kuthana bwino ndi zovuta monga "zosawoneka bwino" ndi "mawonekedwe olakwika" a malo osungira mpweya wa shale.

Kuphatikiza apo, gululi lidachita upainiya wosiyana siyana wokometsa gasi wakuya wa shale, ndikupanga njira yopangira ma volumetric fracturing. Kupambanaku kumapanga maukonde anjira zolumikizana mobisa, zomwe zimapangitsa kuti gasi wa shale aziyenda bwino pamwamba. Chotsatira chake, luso lachitukuko lapita patsogolo kwambiri, ndikuwonjezeka kwakukulu kwa nkhokwe zomwe zingabwezedwe pachuma pachitsime.

Mafuta a gasi wa shale m'chigawo chakum'mwera kwa Sichuan chagawidwa mochuluka komanso chochuluka, kusonyeza kuti angathe kufufuza ndi chitukuko. Zomwe zili m'dera lapakati pakukula kwa malo osungira gasi wa shale komanso kuwonjezeka kwa kupanga kumwera kwa Sichuan, chiphaso chokwanira cha Yongchuan Shale Gas Field ndi chofunikira kwambiri pakuwonetsetsa chitetezo champhamvu cha dziko.

Kupita patsogolo, tidzapititsa patsogolo chitukuko cha gasi wa shale m'chigawo cha kum'mwera kwa Sichuan pokwaniritsa njira yathu "yopanga midadada yotsimikiziridwa, kuyesa midadada yomwe ingathe kuchitika, ndi kuthana ndi midadada yovuta" nthawi imodzi. Njira iyi ikuthandizira kupititsa patsogolo mphamvu zogwiritsira ntchito posungira komanso kubwezeredwa kwa gasi.

Sinopec yakhala ikupititsa patsogolo ntchito yofufuza ndi kukonza zinthu zakuya zagasi wachilengedwe ku Sichuan Basin. Mtsinje wa Sichuan uli ndi zinthu zambiri zakuya zamafuta ndi gasi zomwe zimatha kuwunikira zinthu zambiri, zomwe zimapangitsa kuti "Deep Earth Engineering · Sichuan-Chongqing Natural Gas Base" kukhala gawo lofunikira kwambiri pa ntchito ya Sinopec ya "Deep Earth Engineering".

Kwa zaka zambiri, Sinopec yapita patsogolo kwambiri pakufufuza kwakuya kwamafuta ndi gasi ku Sichuan Basin. Pankhani ya gasi wamba wamba, kampaniyo idapeza motsatira malo a Puguang Gas Field, Yuanba Gas Field, ndi Western Sichuan Gas Field. Pofufuza kwambiri gasi wa shale, Sinopec yatsimikizira malo anayi akuluakulu a gasi iliyonse yomwe ili ndi nkhokwe zopitirira ma kiyubiki metres 100 biliyoni: Weirong Gas Field, Qijiang Gas Field, Yongchuan Gas Field, and Hongxing Gas Field. Zomwe zapindulazi zimapereka chidziwitso chofunikira pakutsegula kwathunthu chuma cha shale ndi mphamvu yopangira ku China ndikuthandiza kwambiri pachitukuko chobiriwira ndi mpweya wochepa.

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 sitinapatulidwe koyambirira, zimatha kupangitsa kuti mapaipi, mavavu, ma compressor ndi zida zina ziwonongeke, kapena kuyambitsa kutsekeka kwa mapaipi m'magawo otsika, 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. Kuwonjezera pa shale gasi desanders, mongaCyclone Desander yochita bwino kwambiri, Wellhead Desander, Cyclonic Well mtsinje wakuda Desander Ndi Ceramic Liners, Jakisoni wamadzi Desander,Gasi Wachilengedwe Desander, ndi zina.

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.
