Izindaba ezinhle kakhulu! Kutholwe insimu enkulu yegesi elinganiselwa ku-100 billion cubic meters eSichuan Basin!

NgoMeyi 13, ngokusho kwehhovisi lezindaba le-Sinopec, iphrojekthi ye-Sinopec ethi “Deep Earth Project · Sichuan-Chongqing Natural Gas Base” izuze enye impumelelo. Ihhovisi lezinsiza zemvelo likhishwe imiphumela yokuhlola amaminerali: izinsiza zamaminerali eziqinisekisiwe ezingu-235.687 billion cubic meters ezivela enkundleni yegesi ye-shale iDongfeng eZiyang, Sichuan, eyethulwe yiSinopec Southwest Oil & Gas Branch, sezivunyiwe yithimba lochwepheshe leHhovisi lezinsiza zemvelo. Lokhu kubeka ukuzalwa kwenkundla yegesi ye-shale enkulu, enezigidigidi zamamitha cubic eChina, okuphumelele ukuthuthukisa ukuhlola nokuthuthukiswa kwegesi ye-shale endaweni entsha enkulu kakhulu, lapho kungcwatshwe khona amamitha angaphezu kuka-4,500. Lokhu kumela ukugxuma okuyisihluthulelo kwegesi ye-shale yaseChina kusuka ezindaweni ezijulile kuye kwezikhulu kakhulu, futhi kuyisikhathi esibalulekile sokuqhubeka nokuqinisa isisekelo sokuphepha kwamandla kazwelonke nokwandisa isikhala sokubuyisela samasu sokukhula okukhulu kwezinsiza nokwanda kokukhiqiza.

Insiza yegesi yeshaysi yaseZiyang Dongfeng itholakala eSichuan Basin futhi iyinsiza enkulu, egcwele ngokuphelele yegesi eyatholwa ngaphakathi kwesigaba samatshe eshaysi i-Cambrian Qiongzhusi. Itshe le-Cambrian limelela isigaba samatshe esidala kunazo zonke emhlabeni esithole okutholakele okukhulu, esakheka eminyakeni eyizigidi ezingu-540 eyedlule. Ngobujulu bokungcwatshwa obusuka ku-4,500 kuye ku-5,200 amamitha, ibeka izinselele ezinkulu zobunjiniyela ngenxa yezici ezingacacile zesitoreji, izindlela ezingaziwa zokuqoqwa nokuceba kwama-hydrocarbon, izigaba ezijiyile nezinzima ukugadla, kanye namazinga okushisa aphezulu nengcindezi ephezulu. Ngenxa yalokho, ukuhlola kwayo nokuthuthukiswa kwayo kubonwa njengenselele yezinga lomhlaba.

Kwenziwe izinto ezintsha emibonweni ye-geological futhi kufezeke impumelelo kwezobuchwepheshe obubalulekile. Ngokuqondene nokuqonda okuyimfundiso, iqembu lokucwaninga likhululekile emikhawulweni yemibono yangaphambili yokuhlola ugesi we-shale, lakha ukuqonda okusha ngokuqoqwa nokuceba kukagesi we-shale e-Cambrian Qiongzhusi Formation, futhi lavula umngcelele omusha wokubuyisela ugesi we-shale. Ngokuqondene nempumelelo kwezobuchwepheshe, ubuhlakani bokwenziwa buhlanganiswe ohlelweni lobuchwepheshe bokuhlola i-geophysical — njengokwenza i-CT scan ezindaweni ezingaphansi komhlaba — okuvumela ukuthi "kuhlonzwe ngokucacile izindawo ezinama-reservoir futhi kubonakale ukuqoqwa kukagesi." Ngaleso sikhathi, kufezeke impumelelo ekugojweni kukagesi we-shale ongajulile kakhulu, ukwaphulwa, kanye nobuchwepheshe obunye, okuholele ohlelweni lobuchwepheshe oluzenzakalelayo ngokuphelele lokuhlola nokuthuthukisa ugesi we-shale ongajulile kakhulu we-Cambrian.

ULiu Wei, uMkhuzi weBhodi kanye noNobhala weQembu weSinopec Southwest Petroleum Bureau Co., Ltd., kanye noMmele weSinopec Southwest Oil & Gas Branch, uthe ngemva kweminyaka engaphezu kweshumi yemizamo eqinile kanye nocwaningo oluqhubekayo, inkampani izuze igxume kusuka ku-“zero” kuye ku-“hundred billion cubic meter scale reserves” ku-Cambrian Qiongzhusi Formation shale gas. Lokhu kuqinisekisa ukuthi le ngqimba ye-shale inamandla amakhulu okuthuthukiswa ngesikali esikhulu. Indlela yezobuchwepheshe ephindeka futhi edluliselwa isungulwe, yandisa kakhulu izinga lokuthuthukiswa kwezinsiza ze-shale gas e-China. Ngokuya phambili, inkampani izoqhubeka nokuqhubekisela phambili ukuhlola kwekhwalithi ephezulu kanye nokuthuthukiswa okuphumelelayo kwezinsiza zikawoyela negesi, ukusheshisa ukwanda kwezinsiza kanye nokukhiqizwa kwenkundla ye-Ziyang Dongfeng shale gas, futhi ibambe iqhaza ekuvikelweni kokuphepha kwamandla kazwelonke.

Ukwenziwa kukagesi we-shale kudinga imishini ebalulekile yokukhipha isihlabathi njengama-desander.

Ukukhipha isihlabathi kukagesi we-shalekuchaza inqubo yokukhipha izinto eziqinile ezifana nezinhlamvu zesihlabathi, isihlabathi sokuqhekeka (proppant), nemidala yamatshe kusuka emifuleni kagesi we-shale (enezinga lamanzi) ngezindlela ezingokomzimba noma zemishini ngesikhathi sokukhiqizwa kukagesi we-shale nokukhiqizwa kwawo.

Njengoba igesi elishiyekile likhishwa ikakhulukazi ngobuchwepheshe bokukhiqiza uqhekeko (ukukhiqiza uqhekeko), uketshezi olubuyayo ngokuvamile luqukethe inqwaba yamatshe angaphakathi komhlaba kanye nezingcezwana ze-ceramic eziyinsalela ezivela ekuqhekekeni. Uma lezi zingcezwana eziqinile zingahlukaniswa ngokuphelele ekuqaleni kokuhamba komsebenzi, zingadala ukuguguleka okukhulu emapayipini, emavalvu, kuma-compressor nezinye izinto zokusebenza, noma zibangele ukuvaleka kwamapayipi ezindaweni eziphansi, ukuvaleka kwamapayipi okuqondisa ingcindezi, noma kubangele izigameko zokuphepha ekukhiqizeni.

I-SAGA's shale gas desander iletha ukusebenza okungajwayelekile ngokukwazi kwayo ukuhlukanisa ngokunembayo (ukususa okungu-98% wezinhlayiya ezingama-micron eziyi-10), izitifiketi eziphethwe yiziphathimandla (isitifiketi se-ISO esikhishwe yi-DNV/GL kanye nokuhambisana ne-NACE anti-corrosion), nokuqina okuhlala njalo (kunezicelo zangaphakathi zobumba ezimelana nokuguga ezinezakhiwo ezivimbela ukuminyana). Yakhelwe ukusebenza kahle kalula, inikeza ukufakwa okulula, ukusebenza nokugcinwa okulula, kanye nokuphila okwandisiwe kwensizakalo – okuyenza ibe yisisombululo esihle kakhulu sokukhiqiza i-shale gas ethembekile.

Inkampani yethu izibophezele njalo ekuthuthukiseni i-desander esebenza kahle kakhulu, encane, futhi engabizi kakhulu ngenkathi iphinde igxile ezintweni ezintsha ezinobungani nemvelo.

Ama-desander e-SAGA aasetshenziswa kuma-platform okungena emthonjeni nama-platform okukhiqiza emikhakheni kawoyela negesi njenge-CNOOC, i-PetroChina, i-Malaysia Petronas, i-Indonesia, i-Gulf of Thailand, nezinye. Aasetshenziswa ukususa ama-solids egazini noma uketshezi lomthombo noma amanzi akhiqiziwe, kanye nokususwa kokuqina kolwandle noma ukubuyiselwa kokukhiqiza. Ukujova amanzi nokugeleza kwamanzi ukwandisa ukukhiqiza nezinye izikhathi.

Le yesikhulumi esihamba phambili siye sabeka i-SAGA njengomhlinzeki wesixazululo owaziwa emhlabeni wonke kwezobuchwepheshe bokulawula nokuphatha izinto eziqinile. Sihlala sibeka phambili izintshisekelo zamakhasimende ethu futhi siphishekela intuthuko ehlangene nabo.
