▲Isizindalwazi Sekhasi Elibomvu 16 Lokuhlola Nokuthuthukiswa
Ngomhla zingama-21 ku-Agasti, kumenyezelwa ehhovisi lezindaba lase-Sinopec ukuthi i-Hongxing Shale Gas Field esetshenziswa yi-Sinopec Jianghan Oilfield ithole ngempumelelo isitifiketi ku-Ministry of Natural Resources ngezinqolobane zayo ezifakazelwe zegesi ye-shale engu-165.025 billion cubic metres. Lesi senzakalo esiyingqopha-mlando siphawula ukugunyazwa ngokusemthethweni kwenye indawo enkulu yegesi ye-shale e-China, okubonisa futhi amandla abalulekile ezinsiza endaweni yase-Hongxing. Ukuthuthukiswa okuyimpumelelo kwalesi siqiwu esisha seqhinga legesi ye-shale kudlala indima enhle ekuqinisekiseni ukuvikeleka kwamandla esizweni.
Ukuphumelela Kwethiyori Nobunjiniyela Kuvulwe “Amakhodi Amandla” Angaphansi Komhlaba.
Itholakala esiFundazweni sase-Hubei kanye noMasipala wase-Chongqing, i-Hongxing Shale Gas Field iqondise ukwakheka kwe-Permian ekujuleni kwamamitha angu-3,300 kuya ku-5,500, ebonakala ngokuwohloka kwesakhiwo okuyinkimbinkimbi kanye nezinselele ezinkulu zokuhlola nentuthuko. I-Sinopec Jianghan Oilfield inobuchwepheshe obuphambili obuphambili bokukhipha igesi ye-shale enezingqimba ezincane ngaphansi kwezimo eziyinkimbinkimbi, isungula imibono yokunothisa igesi ye-shale kanye nokuthuthukisa ukuhlanganiswa kobunjiniyela be-geology. Ngokuhlonza “izindawo ezinoshukela ezikabili zobunjiniyela bokwakheka komhlaba” ukuze kuthuthukiswe igesi ye-shale, le phrojekthi ibe yimpumelelo enkulu ekuhloleni kwe-shale kwe-shale kwe-trillion-cubic-metres eChina ohlelweni olusha lwe-stratigraphic ngale kweNkathi ye-Silurian.
Ukwengeza, ithimba labacwaningi lithuthukise ubuchwepheshe obusha bokuphothula kahle okuvundlile okuphephile kanye nokuvuselela inkimbinkimbi yokuphuka kwe-conductivity ephezulu, okwandisa ukukhiqizwa kokuhlolwa komthombo owodwa kusuka ku-cubic metres angu-89,000 ngosuku kuya ku-323,500 cubic metres ngosuku.

Isikhulu esiphezulu se-Jianghan Oilfield sithe esigabeni esilandelayo, iSinopec izothuthukisa ukuhlola nokuthuthukiswa okudidiyelwe kanye nokuthunyelwa, ijulise ucwaningo ngobuchwepheshe obubalulekile obuhlanganisa i-geology eyisisekelo, amasu okuthuthukiswa, nezinqubo zobunjiniyela, ngokuqhubekayo yandise izindawo ezintsha zokukhula kwe-shale gas reserve ku-Wujiaping Formation, futhi ikhuthaze ngenkuthalo izisekelo ezintsha zokukhiqizwa kwe-shale ye-Per-scale enkulu.

I-Sinopec ibilokhu ishayela ngokungaguquki ukuthuthukiswa kwekhwalithi ephezulu yemboni yegesi ye-shale yaseChina. Iphrofayili yensiza yaseShayina ibonakala “ngokuchichima kwamalahle, uwoyela oyivelakancane, kanye negesi eyivelakancane,” okuyenza ibe umthengi omkhulu wesikhathi eside kawoyela negesi. Ukuhlolwa nokuthuthukiswa kwegesi ye-shale kubambe ukubaluleka kwamasu okubalulekile endaweni yaseShayina yamandla. I-Sinopec iwuthwale ngenkuthalo umthwalo wemfanelo wokuthola izinsiza zegesi yemvelo esizweni. Ekupheleni konyaka wezi-2012, ukutholakala kwe-Fuling Shale Gas Field kwaphawula ukuqala kokuthuthukiswa kwegesi ye-shale e-Shale, nokubeka izwe njengelesithathu ngemva kwe-United States ne-Canada ukuzuza ukukhiqizwa kwegesi ye-shale.
Ngo-2017, iSinopec yaphothula ukwakhiwa kwendawo yokuqala yegesi ye-shale yaseShayina enamandla onyaka angama-cubic metres ayizigidi eziyizinkulungwane eziyi-10—iFuling Shale Gas Field. Ngo-2020, isigaba sokuqala se-Weirong Shale Gas Field saqedwa, saba indawo yokuqala yegesi ye-shale ejulile yaseShayina enemithombo eqinisekisiwe engaphezu kwama-cubic metres ayi-100 billion. Ngo-2024, imithombo yokuhlola efana ne-Jinye 3 kanye ne-Ziyang 2 e-Sichuan Basin yavula amathuba amasha okunwetshwa okubekiwe kanye nokukhula kokukhiqiza.
Kuze kube manje, iSinopec isisungule inkambu eyodwa yegesi ye-shale eyi-trillion-cubic-meter-scale (Fuling) kanye nezizinda ezine zegesi ye-shale ejulile enemithombo engaphezu kwama-cubic metres ayizigidi eziyizinkulungwane eziyi-100 lilinye (i-Weirong, i-Qijiang, i-Yongchuan, ne-Hongxing), iqhubeka ifaka umfutho wamandla ahlanzekile ekuthuthukisweni kwekhwalithi ephezulu.
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 ukuguguleka okukhulu kwamapayipi, ama-valve, ama-compressor nezinye izinto zokusebenza, noma kuholele ekuvinjweni kwamapayipi ezigabeni eziphansi, ukuvala amapayipi okuqondisa umfutho wensimbi, noma kubangele izigameko 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 kwama-desander egesi ye-shale, njenge-High-efficiency Cyclone Desander, Wellhead Desander, Cyclonic Well stream crude Desander With Ceramic Liners, Water injection Desander, Natural Gas Desander, 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.
