I-China ifumanisa enye indawo enkulu yerhasi enovimba we-100 billion cubic metres!

Ngomhla we-14 ka-Agasti, ngokweofisi yeendaba yaseSinopec, enye impumelelo enkulu yaphunyezwa kwiprojekthi ethi "Deep Earth Engineering · Sichuan-Chongqing Natural Gas Base". I-Southwest Petroleum Bureau yaseSinopec ingenise i-Yongchuan Shale Gas Field's indawo yogcino lwegesi eqinisekisiweyo esanda kuqinisekiswa eyi-124.588 billion cubic metres, eyamkelwe ngokusesikweni ligqiza leengcaphephe elisuka kwi-Ofisi yoMphathiswa weMithombo yeNdalo. Oku kuphawula ukuzalwa komnye ummandla omkhulu, onzulu, kunye nohlanganisiweyo werhasi ye-shale e-China enovimba ongaphaya kwe-100 yeebhiliyoni zee-cubic metres, ebonelela ngenkxaso eyomeleleyo yesiseko somthamo wemveliso we-Sichuan-Chongqing 100-billion-cubic-meter. Iza kuba negalelo ekuboneleleni ngamandla acocekileyo kuphuhliso lweBhanti loQoqosho loMlambo iYangtze.

Indawo yerhasi ye-Yongchuan Shale, ehlelwa njengequla elinzulu lerhasi ye-shale, ikwiSithili saseYongchuan, eChongqing, ngaphakathi kwesakhiwo esixandileyo esisemazantsi eSichuan Basin. Iindlela eziphambili ezithwala igesi zilele kubunzulu obudlula i-3,500 yeemitha.

Ngo-2016, uphononongo olukhulu lwaphunyezwa xa i-Well Yongye 1HF, i-apreyizali yokuqala ibekwe kakuhle yi-Sinopec Southwest Petroleum Bureau kule ngingqi, yafumana ngempumelelo i-Yongchuan Shale Gas Field. Ngo-2019, i-23.453 yeebhiliyoni zee-cubic metres eyongezelelweyo yogcino lwejoloji eqinisekisiweyo yaqinisekiswa liqela leengcali elivela kwiSebe lezeNdalo.

Emva koko, iSinopec iye yaqinisa iinzame zokuphonononga kumbindi-mntla weYongchuan onzima ngakumbi, yoyisa imiqobo ebalulekileyo yobugcisa. Oku kuphelele kwisiqinisekiso esipheleleyo seNdawo yerhasi ye-Yongchuan Shale, kunye noovimba bejoloji abaqinisekisiweyo bebonke bafikelela kwi-148.041 yeebhiliyoni zee-cubic metres.

Ubuchwephesha obuTshayo benza igesi ye-Shale enzulu "ibonakale" kwaye "ifikeleleke"

Iqela lophando liqokelele umthamo omkhulu wedatha ye-3D ye-seismic echaneke kakhulu kwirhasi enzulu ye-shale kwaye yaqhuba imijikelo emininzi yezifundo ezidibeneyo zobunjineli be-geological-geophysical-engineering. Baphuhlise itekhnoloji ephucukileyo, kubandakanywa iindlela ezintsha zokwakheka kweemephu kunye nobuchule bokucinga obuphezulu, ukujongana ngokufanelekileyo nemingeni efana "nokungabonwa kakuhle" kunye "nophawu olungachanekanga" lwemithombo yegesi enzulu ye-shale.

Ukongeza, iqela libe nguvulindlela kwindlela eyahlukanisiweyo yokuvuselela irhasi enzulu ye-shale, ivelisa ubuchule obuphezulu bokuqhutywa kwe-volumetric fracturing. Le mpumelelo idala uthungelwano lweendlela ezidityanisiweyo eziphantsi komhlaba, zenza ukuba irhasi ye-shale ihambe ngokufanelekileyo kumphezulu. Ngenxa yoko, impumelelo yophuhliso iye yaphucuka kakhulu, ngokunyuka okuphawulekayo koovimba abanokubuyiswa ngokwezoqoqosho kwiqula ngalinye.

Ubutyebi berhasi ye-shale kwisakhiwo esintsonkothileyo esisemazantsi eSichuan Basin zisasazwe ngokubanzi kwaye zininzi, zibonisa ukuphononongwa okukhulu kunye namandla ophuhliso. Ifakwe kwindawo engundoqo yokukhula kovimba werhasi ye-shale kunye nokwanda kwemveliso kumazantsi eSichuan, isiqinisekiso esipheleleyo se-Yongchuan Shale Gas Field sibambe ukubaluleka okubalulekileyo ekuqinisekiseni ukhuseleko lwamandla esizwe.

Ukuqhubela phambili, siza kuqhubela phambili ngokuthe ngcembe uphuhliso lwerhasi ephuma ematyeni kwingingqi esemazantsi eSichuan ngokuphumeza isicwangciso-qhinga sethu “sokuphuhlisa iibhloko ezivunyiweyo, ukuvavanya iibhloko ezinokuthi zibe kho, kunye nokuqubisana neebhloko eziyimingeni” ngaxeshanye. Le ndlela iya kuqhubeka iphucula zombini ukusetyenziswa kakuhle kogcino kunye namazinga okufumana kwakhona indawo yegesi.

I-Sinopec ibisoloko iqhubela phambili uphononongo kunye nophuhliso lwemithombo yerhasi yendalo enzulu kwiSichuan Basin. ISichuan Basin inobuncwane obuninzi obunzulu be-oyile kunye nerhasi obunamandla okuhlola, okwenza “ubuNjineli boMhlaba obunzulu · iSiseko seGesi yeNdalo yaseSichuan-Chongqing” ibe yinxalenye ebalulekileyo yenyathelo leSinopec “loBunjineli boMhlaba obunzulu”.

Ukutyhubela iminyaka, iSinopec yenze inkqubela phambili ebonakalayo kuphononongo olunzulu lwe-oyile kunye negesi kwiSichuan Basin. Kwintsimi yerhasi yendalo enzulu yesiqhelo, inkampani iye yafumanisa ngokulandelelana iNdawo yeGesi yasePuguang, iNdawo yegesi yaseYuanba, kunye neNdawo yegesi yeSichuan eNtshona. Kuphononongo olunzulu lwerhasi ye-shale, iSinopec iqinisekise iindawo ezine ezinkulu zerhasi ye-shale kwindawo nganye enovimba ongaphezulu kwe-100 leebhiliyoni zee-cubic metres: i-Weirong Gas Field, i-Qijiang Gas Field, i-Yongchuan Gas Field, kunye ne-Hongxing Gas Field. Ezi mpumelelo zibonelela ngeembono ezixabisekileyo zokuvula ngokupheleleyo izibonelelo ze-shale zase-China kunye nomthamo wemveliso ngelixa usenza igalelo elibalulekileyo kuphuhliso lohlaza kunye nekhabhoni ephantsi.

Ukuveliswa kwerhasi ye-shale kufuna izixhobo eziyimfuneko zokususa isanti njenge-desanders.

Ukuchithwa kwerhasi ye-shale kubhekisa kwinkqubo yokususa ubumdaka obuqinileyo obufana neenkozo zesanti, isanti eqhekekileyo (ipropant), kunye nokusikwa kwamatye ukusuka kwimijelo yerhasi ye-shale (ngamanzi angenisiweyo) ngeendlela ezibonakalayo okanye zoomatshini ngexesha lokutsalwa kunye nokuveliswa kwerhasi ye-shale.

Njengoko irhasi ye-shale ifumaneka ikakhulu ngeteknoloji yokuqhekeka kwe-hydraulic (i-fracturing extraction), ulwelo olubuyisiweyo luhlala luqulathe izixa ezikhulu zeenkozo zesanti ezisuka kulwakhiwo kunye nentsalela yamasuntswana e-ceramic aqinileyo ukusuka kwimisebenzi yokuqhekeka. Ukuba la masuntswana aqinileyo awahlukananga ngokupheleleyo ekuqaleni kokuhamba kwenkqubo, anokubangela ukuguga kakhulu kwimibhobho, iivalve, icompressors kunye nezinye izixhobo, okanye zikhokelela ekuvalelekeni kwemibhobho kumacandelo asezantsi, ukuvala imibhobho yesikhokelo soxinzelelo lwesixhobo, okanye ukuqalisa iziganeko zokhuseleko lwemveliso.

I-desander yerhasi ye-SJPEE inikezela ngentsebenzo ebalaseleyo ngokuchaneka kwayo ukwahlula (izinga le-98% lokususa i-10-micron particles), iziqinisekiso ezigunyazisiweyo (i-DNV/GL-ikhutshiweyo yesatifikethi se-ISO kunye nokuthotyelwa kwe-NACE yokuchasana nomhlwa), kunye nokuqina okuhlala ixesha elide (okune-anti-corrosion design yangaphakathi). Yenzelwe ukusebenza ngokufanelekileyo, inika ukufakwa lula, ukusebenza okulula kunye nokugcinwa, kunye nobomi benkonzo eyandisiweyo-iyenza ibe sisisombululo esona sisombululo sithembekileyo sokuveliswa kwegesi ye-shale.

Inkampani yethu izibophelele ngokuqhubekayo ekuphuhliseni i-desander esebenza ngakumbi, ehlangeneyo, kunye nexabiso eliphantsi ngelixa igxile ekusungulweni okuhambelana nokusingqongileyo.

Iidesander zethu ziza kwiindidi ezininzi ezahlukeneyo kwaye zinezicelo ezibanzi. Ukongeza kwi-shale gas desanders, njengeI-High-efficiency Cyclone Desander, Wellhead Desander, I-Cyclonic Well isasaza iDesander ekrwada ngeeLiner zeCeramic, Inaliti yamanzi iDesander,I-Desander yeGesi yeNdalo, njl.

I-desanders ye-SJPEE isetyenziswe kumaqonga eentloko kunye namaqonga emveliso kwiindawo zegesi kunye neoyile ezifana neCNOOC, iPetroChina, iMalaysia Petronas, i-Indonesia, iGulf yaseThailand, kunye nezinye. Zisetyenziselwa ukususa izinto eziqinileyo kwigesi okanye kumanzi amanzi okanye amanzi avelisiweyo, kunye nokususwa kokuqina kwamanzi olwandle okanye ukubuyiswa kwemveliso. Isitofu samanzi kunye nokukhukula kwamanzi ukwandisa imveliso kunye nezinye izihlandlo.

Eli qonga liphambili libeke i-SJPEE njengomboneleli wesisombululo owaziwayo kwihlabathi jikelele kulawulo oluluqilima kunye netekhnoloji yolawulo. Sisoloko sibeka phambili umdla wabathengi bethu kwaye silandele uphuhliso olufanayo kunye nabo.
