Jimusar shale oil

Saliida Jimusar shale waa aagga mudaaharaad ee shiinaha ee ugu horeeyay ee qaran ee shale shale, oo ku yaal qaybta bari ee Jungar Basin. Waxay daboolaysaa bed dhan 1,278 kiiloomitir laba jibaaran waxayna leedahay kayd kayd ah oo lagu qiyaasay 1.112 bilyan oo tan. 2018, horumarinta baaxadda weyn ee Saliida Jimusar shale ayaa bilaabmay. Saddexdii bilood ee ugu horreeyay, Xinjiang Jimusar National Terrestrial Shale Oil Aagga Mudaaharaadka ayaa soo saaray 315,000 oo tan oo saliid shale ah, taasoo dhigaysa rikoor cusub oo taariikhi ah. Aagga bannaan-baxa ayaa dardargelinaya dadaallada lagu kordhinayo kaydka iyo soo-saarka saliidda Shale, iyadoo la qorsheynayo in sannadka 2024-ka lagu dhammeeyo 100 ceel laga qodo iyo 110 ceel oo jajaban.

Saliida Shale, oo ah saliid ku dheggan dhagaxa dhagaxa ah ama jeexjeexeeda, waa mid ka mid ah noocyada ugu adag ee saliidda. Xinjiang waxay hodan ku tahay kheyraadka saliidda shale oo leh rajo ballaaran oo sahaminta iyo horumarinta. Shiinuhu waxa uu u aqoonsaday kheyraadka saliida shale in uu yahay aag muhiim u ah bedelka shidaalka mustaqbalka. Wu Chengmei, oo ah injineer sare oo ka tirsan Xarunta Cilmi-baadhista Juquraafi ee Jiqing Oilfield Operations Area ee Xinjiang Oilfield, ayaa sharaxay in saliidda shale ee Jimusar ay guud ahaan ku aasan tahay in ka badan 3,800 mitir dhulka hoostiisa ah. Xabaasha qoto dheer iyo gaar ahaan daxalka hoose ayaa ka dhigaya soo saarista mid dhib badan sida saliidda laga soo saaro dhagaxa.

Horumarka saliidda dhulka ee Shiinaha ayaa guud ahaan wajahaya afar caqabadood oo waaweyn: marka hore, saliiddu aad bay u culus tahay, taasoo adkeynaysa qulqulka; labaad, meelaha macaan waa yar yihiin oo ay adag tahay in la saadaaliyo; saddexaad, maadada dhoobada sare leh ayaa ka dhigaysa jabka adag; afraad, qaybintu waa mid aan is waafaqsanayn, oo adkaynaysa hawlaha. Arrimahan ayaa muddo dheer xaddiday horumarka baaxadda leh ee waxtarka leh ee saliidda shale dhuleed ee Shiinaha. Mashruucu, si loogu daweeyo dareeraha qulqulaya ee jabay, wax lagu daro oo cusub ayaa loo isticmaalaa si loo yareeyo wasakhowga iyo dib-u-warshadaynta dareeraha, dib ugu noqoshada dareeraha dillaaca si dib loogu isticmaalo. Habkan waxaa lagu tijaabiyay sagaal ceel 2023 iyadoo natiijooyin fiican laga helay. Laga bilaabo Juun 2024, mashruucu waxa uu qorshaynayaa in loo isticmaalo dareeraha jaban ee dib loo habeeyay ee hawl jabin balaadhan.

Dhismaha ugu weyn ee mashruuca wuxuu ka kooban yahay dhuxul dhuxul, qaybo cawl iyo bunni ah oo dhoobo ah, kuwaas oo ah qaababka xasaasiga ah ee biyaha. Qeybta saliida ee Jimusar shale, qaybta daloolka furan ee ceelka labaad waa dheer tahay, waxaana la dheereeyey waqtiga abuuritaanka. Haddii dhoobada biyaha ku salaysan la isticmaalo, burburka iyo xasillooni-darrada waxay u badan tahay, laakiin dareeraha qodista saliidda ku salaysan ma keenaan saameyn fuuq-bax. Dheecaannada qodista emulsion-ka ee saliidda, marka ay xasilloon yihiin, sidoo kale ma keenaan saameynaha fuuq-celinta, sidaas darteed dareeraha qodista saliidda ku salaysan ma abuuraan cadaadiska bararka fuuq-celinta. Cilmi-baaristu waxay keentay in la qaato habka dhoobada saliidda ku salaysan, oo leh mabaadi'da ka hortagga burburka iyo tallaabooyinka soo socda: 1. Ka hortagga kiimikada: Xakamaynta saamiga saliidda-biyaha ee ka sarreeya 80: 20 si loo yareeyo wejiga biyaha ee samaynta, si wax ku ool ah looga hortago. barar iyo burbur ku yimaadda tolashooyinka dhuxusha iyo qaababka aadka u xasaasiga ah ee biyaha. 2. Ku xidhid jidheed: Ku darista walxaha miisaanka leh sida kaalshiyamka horeba qaababka daciifka ah si kor loogu qaado awooda cadaadiska samaynta loogana hortago daadinta si fiican. 3. Taageerada makaanikada: Xakamaynta cufnaanta ka sarreysa 1.52g/cm³, si tartiib tartiib ah u kordhinaysa cufnaanta xadka naqshadaynta ee 1.58g/cm³ ee qaybta dhisitaanka. Wakiilada culeyska ee ay soo saartay Shirkadda Youzhu waxay gaari kartaa saameynta la rabo, iyadoo la hubinayo in si habsami leh oo guul leh loo dhammeeyo mashaariicda qodista iyo dhamaystirka si fiican.
