I-China's largest shale oil production base has cumulatively produced over 20 million metric tons！

Ngomhla ziyi-9 kuNovemba, izindaba ezijabulisayo zafika eChangqing Oilfield, okuyisizinda esikhulu sokukhiqiza uwoyela we-shale eChina—ukukhiqizwa kwayo kwe-shale oil sekudlule emathonini angama-20 million. Le miphumela ibonisa impumelelo enkulu ku-"shale revolution" yaseChina futhi ibonisa ukuthi uwoyela we-shale wezwe usungene esigabeni esisha sokuthuthukiswa okukhulu nokonga izindleko.

Ngaphansi kwesimo sokusheshisa kokuguqulwa kwamandla emhlabeni jikelele futhi ngokuhambisana nezidingo ze "Four Revolutions and One Cooperation" isu lokuphepha kwamandla, uwoyela we-shale, njengengxenye ebalulekile yemithombo ye-oil ne-gas engajwayelekile, udlala indima ebalulekile ekuqinisekiseni ukuphepha kwamandla kazwelonke ngokuthuthukiswa kwawo okuphumelelayo. U-Jia Chengzao, umphakathi we-Chinese Academy of Sciences, uthe uwoyela we-shale umele indawo ebalulekile yokukhuthaza ukwanda nokuzinza kokukhiqizwa kwe-crude oil kwasekhaya.

Ishale oil ichazwa ngokuba ne-permeability ephansi kanye ne-fluidity engalungile, okwenza kube nzima kakhulu ukukhipha—ukuvumelana phakathi kwemboni. Ishale oil ehlolwe futhi yathuthukiswa yiChangqing Oilfield itholakala e-Ordos Basin. Izendlalelo zayo ze-reservoir ngokuvamile zine-thickness ye-single-layer engaphansi kwama-5 meters futhi zifihlwe ngaphezu kwama-2,000 meters phansi. I-permeability ingu-1/1000 kuphela kwaleyo ye-conventional oilfields e-China, kanti i-radius yezindlela zayo eziyinhloko zokuhamba ingu-1/30 kuphela kwe-diameter yezinwele zomuntu. Lezi zimo zenze ukuhlola kwe-seismic kanye ne-fracturing ye-reservoir kube nzima kakhulu, zenza ukuba ibizwe ngokuthi "eyinzima kakhulu". Izinqubo zokukhipha ezijwayelekile azisebenzi kahle kulezi zimo.

Ukuze kubhekwe lezi zinkinga, ngaphansi kwePhrojekthi enkulu yezeMvelo neTekhnoloji kazwelonke, iChangqing Oilfield ihlolisise izivivinyo zelebhu eziyi-128,000 futhi yafaka izivivinyo eziphumelelayo ezinkundleni ezingaphezu kwe-80. Ukuphumelela kuqhamuke ngempumelelo emibonweni, emateknoloji, nasezinhlelweni zokuthuthukiswa kokuhlola nokukhiqiza uwoyela we-shale.

Ukuqinisa ucwaningo lwezTheory ukuze kubhekwe umbuzo oyisisekelo othi "ngabe izinsiza ziyatholakala futhi ziphakathi kuphi." I-Changqing Oilfield ikhulise ucwaningo lwezindlela zokuhlanganiswa kwe-shale oil kanye nezindlela zokwandisa, yasungula ukuqonda kweTheory kokuthi "ukuba khona komthombo kanye nesitoreji" ezinhlelweni ze-shale ze-continental ze-basin. Le mpumelelo ikwazile ukuhunyushwa kwemigomo yesayensi engemuva kokuthi "ukukhiqizwa kwe-oyili" kanye "nokugcina kwe-oyili" ku-shale ye-continental, ivula i-Qincheng shale oil field enezinsiza ezingaphezu kwezigidi eziyi-10 zamathani futhi ivula ingcebo ecebile yezinsiza ze-shale oil e-Ordos Basin.

Ngonyaka ka-2018, ngemva kokusungulwa ngokusemthethweni kweqembu lephrojekthi yokwakha amandla okukhiqiza uwoyela we-shale eChangqing Oilfield, akugcini nje ngokusheshisa ukukhiqizwa nokwakhiwa kwe-shale oil kodwa futhi kuqhubele phambili ukudalwa kwesizinda sokuqala esikhulu sokuhlola esiphansi sokuhlinzeka ngamanzi sokuhlola uwoyela we-shale eChina. Kulolu hlelo, leli phakheji lenza ubuchwepheshe bokuthuthukisa umthamo we-shale oil bokuhlukanisa izimbobo ezihambayo, kugxilwe ku-"ukwakhiwa kwe-fracture, ukwandiswa kwamandla okuqala, nokufaka esikhundleni." Ngaphezu kwalokho, ithuthukise ngokwayo ubuchwepheshe obubalulekile obungu-12, kuhlanganise nezikhala ze-metal ezixazululiwe nezifutho zokuhlukanisa eziningi. Ukusetshenziswa kwempumelelo kwalobu buchwepheshe kwakhuphula kakhulu ukukhiqizwa kwe-well eyodwa, kwandisa kusuka kumathani angu-1.5 kuya kumathani angu-18, ngaleyo ndlela kwakha "izitho" ezisebenzayo kanye "nenhliziyo" yokuthuthukiswa kwezinqolobane "eziphumuli."

Iphuli leChangqing liqhubekile nokuthuthukisa "ubuchwepheshe be-shale" ngokuqinile, lihola imodeli yokuthuthukiswa ebonakaliswa "ukubhoboza okuhlangene kwemithombo ye-horizontali, ukuhlanganiswa kwesiteshi esiphathwayo esikhiphayo, ukukhiqizwa kwegesi ehlangene ehlukahlukene, kanye nokusebenza okungenamuntu okwenziwe ngedijithali." Liphumelele ukufaka irekhodi lomhlaba elide kakhulu le-horizontali elidlula amamitha angama-5,000 kanye nerekhodi lase-Asia lokusebenzisa imithombo ye-horizontali engu-31 kusuka epulatifomu eyodwa. Ngasikhathi sinye, ngokuhamba phambili kokwethulwa kwenkundla ye-IoT ye-shale oil yokuqala eChina kanye nohlelo lokuhlola lwe-UAV olukhulu kunazo zonke, izidingo zabasebenzi ngezigidi eziyi-1 zokukhiqiza zehlele ngama-80%, kusungulwa njengomfanekiso wokuqala ophumelelayo wezwe wokuthuthukiswa kwe-shale oil okwenziwe ngamasu amakhulu futhi aphumelelayo.

Ngonyaka ka-2024, ukukhiqizwa kwe-shale oil kwe-Changqing Oilfield kwaba ngaphezu kwengxenye yesibili yokukhiqizwa kwe-shale oil kwazulu, kwenza kube isizinda esikhulu sokukhiqiza i-shale oil ezweni. Kusukela ekuqaleni konyaka, ukukhiqizwa kwe-shale oil nokwakhiwa kuqhubekile nokusheshisa. Kuze kube manje, amahluzi angu-144 e-shale oil aphelile, ukukhiqizwa kwe-shale oil kudlule emathonini angama-3 million. Izinga lokukhiqiza nsuku zonke lidlule emathonini angama-10,000 okokuqala, lwenza kube irekhodi elisha lesizwe.

Ukukhiqizwa kwe-shale gas kudinga imishini ebalulekile yokukhipha isihlabathi efana nezinsiza zokukhipha isihlabathi.

Igesi ye-shale desandingkubhekisela enqubweni yokukhipha izinto ezingcolile eziqinile ezifana nezihlabathi, ukwephuka kwesihlabathi (proppant), kanye nezinsalela zezitshalo emithonjeni ye-shale gas (enamanzi angaphakathi) ngokuqhuba izindlela zomzimba noma ezisebenzayo ngesikhathi sokukhipha nokukhiqiza i-shale gas.

Njengoba igesi ye-shale itholakala ikakhulukazi nge-technology yokuphula amanzi (ukukhishwa kokuphula), umswakama obuyisiwe uvame ukuqukethe inani elikhulu lezinhlayiya zetsandstone ezivela emhlabeni kanye nezinsalela ze-ceramic eziqinile ezivela ezinqubweni zokuphula. Uma lezi zinhlayiya eziqinile zingahlukaniswa ngokuphelele ekuqaleni kwenqubo, zingadala ukugqwala okukhulu kumapayipi, ama-valve, ama-compressor nezinye izinto, noma zikhokele ekubambeni amapayipi ezindaweni eziphakeme, ukuvinjwa kwamapayipi okukhombisa ingcindezi, noma ziqhubele phambili izigameko zokuphepha kokukhiqiza.

I-SAGA's shale gas desander iletha ukusebenza okuhle kakhulu ngekhono layo lokuhlukanisa ngok точность (98% yokususwa kwezingxenye ezingu-10-micron), izitifiketi ezinamandla (i-DNV/GL-ikhishwe i-ISO certification kanye ne-NACE anti-corrosion compliance), kanye nokuhlala isikhathi eside (inezinto ze-ceramic eziphikisana nokugqwala ezine-design yokuvikela ukuvimbela). Yakhiwe ukuze kube nokusebenza okungathathi isikhathi, inikeza ukufakwa okulula, ukusebenza okulula nokugcinwa, kanye nempilo yesevisi ende – okwenza kube isixazululo esifanele sokukhiqiza i-shale gas ethembekile.

Inkampani yethu iqhubeka nokuzinikela ekuthuthukiseni izinsiza zokuhlunga ezisebenza kahle, ezincane, nezisebenza kahle kwezindleko, ngenkathi igxila futhi ezintsha ezihambisana nemvelo.

I-desander zethu ziza ngezinhlobo eziningi futhi zinezinhlelo eziningi zokusebenza.

I-SAGA's desanders isetshenziswe ezinkundleni zokukhiqiza nezinkundleni zokukhiqiza emithonjeni ye-gas ne-oyela efana ne-CNOOC, i-PetroChina, i-Malaysia Petronas, i-Indonesia, i-Gulf of Thailand, nezinye. Zisetshenziselwa ukususa izinto eziqinile emanzini e-gas noma emanzini e-well noma emanzini akhiqiziwe, kanye nokususwa kokuhlangana kwamanzi olwandle noma ukuvuselelwa kokukhiqiza. Ukufaka amanzi nokugeleza kwamanzi ukuze kukhuphule ukukhiqiza nezinye izikhathi.

Le ndawo ephakeme ibeke i-SAGA njengomhlinzeki wesixazululo owaziwa emhlabeni jikelele kwezobuchwepheshe bokulawula nokuphathwa kwezakhiwo eziqinile. Sihlala sithathela phezulu izinzuzo zamakhasimende ethu futhi sikhuthaza ukuthuthukiswa okuhlanganyelwe nabo.
