Ngo-Agasti 14, ngokwehhovisi lezindaba laseSinopec, enye impumelelo enkulu yafinyelelwa kuphrojekthi ethi “Deep Earth Engineering · Sichuan-Chongqing Natural Gas Base” iphrojekthi. I-Southwest Petroleum Bureau yase-Sinopec ithumele izindawo zokugcina eziqinisekisiwe ezisanda kuqinisekiswa ze-Yongchuan Shale Gas Field ezingama-cubic metres ayizigidi eziyizinkulungwane eziyi-124.588, ezigunyazwe ngokusemthethweni ithimba lochwepheshe elivela kuMnyango Wezemvelo. Lokhu kuphawula ukuzalwa kwesinye isizinda esikhulu, esijulile, nesididiyelwe segesi ye-shale e-China enemithombo engaphezu kwama-cubic metres ayizigidi eziyizinkulungwane eziyi-100, ehlinzeka ngokusekelwa okuqinile kwesisekelo sokukhiqiza sokukhiqiza i-Sichuan-Chongqing 100-bic-cubic-meter. Izophinde ibe negalelo ekuhlinzekweni kwamandla ahlanzekile ukuze kuthuthukiswe i-Yangtze River Economic Belt.
I-Yongchuan Shale Gas Field, ebhekwa njengendawo yokugcina igesi ye-shale ejulile, itholakala esifundeni sase-Yongchuan, e-Chongqing, ngaphakathi kwesakhiwo esiseningizimu yeSichuan Basin. Izindlela eziyinhloko ezithwala igesi zilele ekujuleni okungaphezu kwamamitha angu-3,500.
Ngo-2016, kwafinyelelwa impumelelo enkulu yokuhlola lapho i-Well Yongye 1HF, ukuhlolwa kokuqala okwasetshenziswa kahle yiSinopec Southwest Petroleum Bureau esifundeni, ithola ngempumelelo i-Yongchuan Shale Gas Field. Ngo-2019, enye i-cubic metres eyizigidi eziyizinkulungwane ezingama-23.453 yezindawo ezigciniwe zokwakheka komhlaba eziqinisekisiwe zagunyazwa yiphaneli yochwepheshe evela kuMnyango Wezemvelo.
Kamuva, iSinopec yaqinisa imizamo yokuhlola endaweni eyinselele emaphakathi nenyakatho yeYongchuan, yanqoba izithiyo ezinkulu zobuchwepheshe. Lokhu kufinyelele umvuthwandaba ngesitifiketi esiphelele se-Yongchuan Shale Gas Field, enezindawo zokugcinwa komhlaba ezifakazelwe ezifinyelela ku-148.041 billion cubic metres.
I-Innovative Technologies Yenza I-Deep Shale Gas “Ibonakale” futhi “Ifinyeleleke”
Ithimba labacwaningi liqoqe umthamo omkhulu wedatha ye-3D enembayo yokuzamazama komhlaba ejulile ye-shale futhi lenza imizuliswano eminingi yocwaningo oludidiyelwe lwe-geological-geophysical-engineering. Bathuthukise ubuchwepheshe obuthuthukisiwe, okuhlanganisa izindlela ezintsha zemephu yesakhiwo kanye namasu okucabanga okunokulungiswa okuphezulu, ukubhekana ngokuphumelelayo nezinselele ezifana "nokungabonwa kahle" kanye "nokubonakala okungalungile" kwamadamu egesi ye-shale ejulile.
Ukwengeza, ithimba lisungule indlela ehlukile yokuvuselela igesi ye-shale, ukusungula indlela ephezulu yokuqhuba i-volumetric fracturing. Lokhu kuphumelela kudala inethiwekhi yezindlela ezixhumene ezingaphansi komhlaba, okuvumela igesi ye-shale ukuthi igeleze kahle phezulu. Ngenxa yalokho, ukusebenza kahle kwentuthuko kuye kwaba ngcono kakhulu, nokwenyuka okuphawulekayo kwezindawo ezigciniwe ezingabuyiselwa ngokomnotho emthonjeni ngamunye.
Imithombo yegesi ye-shale endaweni enesakhiwo esiyinkimbinkimbi eseningizimu ye-Sichuan yasatshalaliswa kabanzi futhi iyinsada, ikhombisa amandla amakhulu okuhlola kanye nentuthuko. Itholakala endaweni eyinhloko yokukhula kwendawo yokugcina igesi ye-shale kanye nokwanda kokukhiqizwa eningizimu yeSichuan, isitifiketi esiphelele se-Yongchuan Shale Gas Field sibaluleke kakhulu ekuqinisekiseni ukuvikeleka kwamandla kazwelonke.
Ukuqhubekela phambili, sizoqhubekisela phambili kancane kancane ukuthuthukiswa kwegesi ye-shale esifundeni esiseningizimu yeSichuan ngokusebenzisa isu lethu “lokuthuthukisa amabhulokhi afakazelwe, ukuhlola amabhlokhi angaba khona, kanye nokubhekana namabhulokhi ayinselele” kanyekanye. Le ndlela izothuthukisa ngokuqhubekayo kokubili ukusebenza kahle kokugcinwa kokusetshenziswa kanye namazinga okuthola kabusha insimu yegesi.
I-Sinopec ibilokhu iqhubekisela phambili ukuhlolwa nokuthuthukiswa kwemithombo yegesi yemvelo ejulile eSigodini saseSichuan. I-Sichuan Basin inezinsiza eziningi ezijulile zikawoyela negesi ezinamandla amakhulu okuhlola, okwenza “I-Deep Earth Engineering · I-Sichuan-Chongqing Natural Gas Base” ibe ingxenye ebalulekile yohlelo lwe-Sinopec “Deep Earth Engineering”.
Eminyakeni edlule, iSinopec yenze inqubekelaphambili ebonakalayo ekuhloleni uwoyela ojulile negesi eSigodini saseSichuan. Emkhakheni wegesi yemvelo evamile ejulile, inkampani ithole ngokulandelana iPuguang Gas Field, Yuanba Gas Field, kanye neWestern Sichuan Gas Field. Ekuhloleni igesi ye-shale ejulile, iSinopec iqinisekise izizinda ezine ezinkulu zegesi ye-shale indawo ngayinye enezindawo ezingaphezu kwe-cubic metres eyizigidi eziyizinkulungwane eziyi-100: i-Weirong Gas Field, i-Qijiang Gas Field, i-Yongchuan Gas Field, kanye ne-Hongxing Gas Field. Lezi zimpumelelo zihlinzeka ngemininingwane ebalulekile yokuvula ngokugcwele izinsiza ze-shale namandla okukhiqiza ngenkathi yenza umnikelo obalulekile ekuthuthukisweni kwekhabhoni eluhlaza kanye nekhabhoni ephansi.
Ukukhiqizwa kwegesi ye-shale kudinga imishini ebalulekile yokukhipha isihlabathi njengama-desander.
Ukuchithwa kwegesi ye-shale kubhekisela ohlelweni lokususa ukungcola okuqinile okufana nezinhlamvu zesihlabathi, isihlabathi esiqhekekayo (i-proppant), kanye nokusikwa kwamadwala emifudlaneni yegesi ye-shale (ngamanzi ahlanganisiwe) ngokusebenzisa izindlela ezibonakalayo noma zemishini ngesikhathi sokukhipha igesi ye-shale kanye nokukhiqizwa.
Njengoba igesi ye-shale itholakala ngokuyinhloko ngobuchwepheshe be-hydraulic fracturing (i-fracturing extraction), uketshezi olubuyiswayo ngokuvamile luqukethe inani elikhulu lezinhlamvu zesihlabathi kusukela ekubunjweni kanye nezinhlayiya ezisele eziqinile ze-ceramic ezivela ekusebenzeni kokuqhekeka. Uma lezi zinhlayiya eziqinile zingahlukanisiwe ngokuphelele ekuqaleni kokugeleza kwenqubo, zingabangela ukuguga okukhulu kwamapayipi, ama-valve, ama-compressor nezinye izinto zokusebenza, noma ziholele ekuvinjweni kwamapayipi ezigabeni eziphansi, ukuvala amapayipi okuqondisa umfutho wensimbi, noma kucuphe izehlakalo zokuphepha zokukhiqiza.
I-shale gas desander ye-SJPEE iletha ukusebenza okukhethekile ngamandla ayo okuhlukanisa ngokunemba (izinga lokususa elingu-98% lezinhlayiya ezingu-10-micron), izitifiketi ezigunyaziwe (isitifiketi se-ISO esikhishwe nge-DNV/GL kanye nokuthobelana kwe-NACE okunqanda ukugqwala), kanye nokuqina okuhlala isikhathi eside (okufaka idizayini ye-ceramic engagugi). Iklanyelwe ukusebenza kahle okungenakuzikhandla, inikeza ukufakwa kalula, ukusebenza okulula nokunakekelwa, kanye nempilo yesevisi eyandisiwe - okuyenza ibe yisixazululo esilungile sokukhiqiza okuthembekile kwegesi ye-shale.
Inkampani yethu izimisele ngokuqhubekayo ekuthuthukiseni i-desander esebenza kahle, ehlangene, futhi engabizi kakhulu kuyilapho igxile ekusungulweni okunobungani kwemvelo.
Ama-desander ethu afika ngezinhlobo eziningi ezihlukahlukene futhi anezinhlelo zokusebenza eziningi. Ngaphezu kwe-shale gas desanders, njengeI-Cyclone Desander esebenza kahle kakhulu, Wellhead Desander, I-Cyclonic Well isakaza i-Desander engahluziwe Nge-Ceramic Liners, Umjovo wamanzi Desander,I-Desander Yegesi Yemvelo, njll.
Ama-desanders e-SJPEE asetshenziswe kumapulatifomu e-wellhead nasezinkundleni zokukhiqiza ezindaweni zegesi namafutha njenge-CNOOC, i-PetroChina, i-Malaysia Petronas, i-Indonesia, i-Gulf of Thailand, nezinye. Asetshenziselwa ukususa izinto eziqinile kugesi noma emanzini oketshezi noma amanzi akhiqiziwe, kanye nokususwa kokuqina kwamanzi olwandle noma ukutholwa kokukhiqiza. Umjovo wamanzi kanye nezikhukhula zamanzi ukwandisa ukukhiqizwa nezinye izikhathi.
Le nkundla yokuqala ibeke i-SJPEE njengomhlinzeki wesixazululo owaziwa emhlabeni wonke ekulawuleni okuqinile nobuchwepheshe bokuphatha. Sihlala sibeka phambili izintshisekelo zamakhasimende ethu futhi siphishekela ukuthuthukiswa okufanayo nawo.
