Inqubekela phambili ebalulekile yenziwe ekuhloleni okujulile kakhulu eTarim Basin: Umthombo Zhentan-1 uthole ama-Cambrian source-rock cores kumamitha angu-8,080

Muva nje, i-PetroChina's Tarim Oilfield ithole imiphumela ebalulekile eminingi ekuhloleni nasekuthuthukisweni okujulile kakhulu. I-Hade–Fuman Oilfield yenze inqubekelaphambili enkulu ekukhiqizweni okuhlanganisiwe kukawoyela negesi emanzini angaphansi kuka-6,000 metres. Ngasikhathi sinye, i-Well Zhentan-1, etholakala e-Wensu County emaphethelweni asenyakatho-ntshonalanga yesifunda, ithole ngempumelelo ama-continuous cores esikhaleni sama-8,080 metres, okusetha irekhodi lesifunda ekutholakaleni kwedatha yokuma komhlaba ejulile.

I-Hade–Fuman Oilfield, etholakala ehlane laseTaklamakan, iyisizinda esikhulu kunazo zonke eChina sokukhiqiza uwoyela negesi emhlabathini ojulile esihlalweni. Kuze kube manje, izindawo zokugcina uwoyela ezinokujula okungaphezu kwamamitha angu-6,000 kule nsimbi zikhiqize isamba samathani ayizigidi ezingu-20.36 kawoyela ongahluziwe kanye namabhiliyoni angu-8.15 amamitha ayisikwele egesi yemvelo, kanti isamba sikawoyela negesi esilingana naso sidlula amathani ayizigidi ezingu-26.86. Le nsimbi isiqedile ukumba imishini yokumba emhlabathini ojulile engu-485, kanti kuyo imishini engu-133 isikhiqize isamba sikawoyela negesi esidlula amathani ayizigidi eziyi-100,000, kanti imishini engu-464 ikhiqize umuntu ngamunye amathani angaphezu kweziyi-10,000. I-Tarim Basin inezindawo zokugcina uwoyela negesi eziqinisekisiwe ezingaphezu kwamabhiliyoni angu-5 amathani, kanti ngaphezu kwengxenye yezinsiza zitholakala ezindaweni ezinokujula okukhulu, okuyisizinda esiyinhloko semizamo yaseChina yokwandisa izindawo zokugcina nokukhiqiza uwoyela negesi.

Izingqophamlando zokuhlola zigqama ngokulinganayo. Ngo-Okthoba 1, i-Well Zhentan-1 yathola umgogodla oqhubekayo ongamamitha angu-6 wetshe lomthombo le-Cambrian Yuertusi Formation ekujuleni kwamamitha angu-8,080. Leli tshe lomthombo, elisukela eminyakeni engaba yizigidi ezingama-500 edlule, lathathwa umgogodla okokuqala ngaphansi kwamamitha angu-8,000 emngceleni osenyakatho-ntshonalanga we-Tarim Basin, linikeza impahla ebalulekile ebonakalayo yokuhlola amandla okukhiqiza uwoyela negesi ezingqimbeni ezijulile kakhulu. Lo mthombo uwumthombo wesibili wokumba owenziwe ngomshini wokumba wokuqala ozimele waseChina onamamitha angu-12,000. Ngo-Okthoba 2, wafinyelela ekujuleni kwamamitha angu-8,345, umgomo wokuhlola ugxile esigxotsheni esikhulu se-Sinian structural trap, okuhloswe ngaso ukuqinisekisa amandla omthombo kazwelonke kanye negesi ejulile emngceleni osenyakatho-ntshonalanga we-basin.

Ukutholakala ngempumelelo kwama-core e-Well Zhentan-1 kungenye indlela yokuhlola okusebenzayo kwama-rigs okumba asezingeni lika-10,000-metre akhiqizwe ekhaya emsebenzini wokuhlola okujulile. Lolu hlelo lunamandla aphezulu okuthwala kanye namakhono okusebenza ngokuzenzakalela, okwephula ukuncika kwesikhathi eside ekuthengweni kwamanye amazwe kwemishini yemigodi ejulile esezingeni eliphezulu, kusekela i-China ekuqhubekeleni phambili eMhlabeni ojulile nasekukhuliseni imingcele yokuhlola uwoyela negesi okujulile kakhulu.

Ngokusebenza okuqinisekisiwe emikhakheni emikhulu yomhlaba esetshenziswa yi-CNOOC, CNPC, Petronas nabanye abasebenzi kulo lonke elaseNingizimu-mpumalanga ye-Asia, ama-desander e-SAGA asetshenziswa emapulatifomu omthombo kanye nasekukhiqizeni. Ahlinzeka ngokususwa okuqinisekile kwezinto eziqinile kugesi, uketshezi lomthombo kanye ne-condensate, futhi adlala indima ebalulekile ekuhlanzeni amanzi olwandle, ekuvikeleni imifudlana yokukhiqiza kanye nezinhlelo zokujova/ukugcwala kwamanzi.

Uhlu olubanzi lwe-SAGA lokuhlukanisa luhlanganisa amasistimu e-membrane okususa i-CO₂ kugesi wemvelo, ama-hydrocyclone okususa uwoyela, amayunithi okuntanta ahlangene asebenza kahle (ama-CFU), ukususa isihlabathi kugesi ye-Shale, iphakethe le-Cyclonic dewatering elinokwelashwa kwamanzi akhiqiziwe, kanye nama-hydrocyclone anamagumbi amaningi, okuhlinzeka ngezixazululo eziphelele ezinseleleni ezinzima kakhulu zemboni.
