Umkhiqizo wonyaka we-Daqing Gulong shale oil we-China National Petroleum Corporation udlula amahlandla angama-10 million tons!

NgoDisemba 5, izintatheli zithole emkhakheni kawoyela wakwaDaqing weChina National Petroleum Corporation ukuthi umkhiqizo wonyaka kawoyela we-shale wakwaDaqing Gulong weqe amathani ayisigidi. Lesi sikhathi esibalulekile sibonisa ukuphothulwa kweminyaka emihlanu yokuhlola nokuthuthukisa umkhakha kawoyela wakwaDaqing, lapho ube nempumelelo ezintweni ezimbili eziyisisekelo: ukunqwabelana kwe-in-situ kawoyela we-shale womhlaba kanye nentuthuko ye-multi-phase, multi-field, multi-scale. Ngaphezu kwalokho, uthuthukise ubuchwepheshe obuhlanu obubalulekile, uzibeke njengesikhungo sobuchwepheshe sokuqala se-shale oil esivela emhlabeni esakhiwe ngama-argillaceous-laminated.

▲ Umsebenzi wepompi ovela Ethimini Lokuhlakaza leNgatsha Yokusebenza Kwemigodi wenza umsebenzi wokugcinwa kwezingxenye ezinomfutho ophakeme endaweni kawoyela we-shale eGulong. Isithombe sikaHan Jing

Uwoyela we-shale waseChina usatshalaliswe kabanzi, unamandla amakhulu okusetshenziswa esikhathini, futhi umthamo wawo wezinsiza udlula owamafutha negesi avamile. Uye waba umthombo obalulekile wamasu wokubuyisela kanye nendawo eyinhloko yokwandisa izinto ezilondoloziwe kanye nokukhiqiza.

Nokho, isikhathi eside, insimu yokuhlola uphethiloli ibilokhu ibheka "ukukhipha uwoyela we-shale njengokunzima kakhulu," ivame ukubizwa ngokuthi "indawo evaliwe" yokuhlola nokuthuthukisa. Uwoyela we-shale waseDaqing Gulong, njengowoyela we-shale we-argillaceous-laminated ongokwemvelo, ikakhulukazi unezimbotshana zamatshe ezinosayizi omncane—ezilinganiselwa ku-1/500 ubukhulu benzwe lomuntu—okwenza ukuthuthukiswa kwawo kube nzima kakhulu. Izinkampani zikaphroleyi ezaziwa emhlabeni wonke zake zathi "ayinawo inani lokuthuthukiswa kwezentengiselwano."

"Izidingo zesizwe yizona ezisishukumisela ukuba sisebenze kanzima, sinikele, futhi singayeki," kusho uZhu Guowen, uNobhala weKomiti yePhathi yeDaqing Oilfield. Ugcizelele ukuthi leli fayili likawoyela ligcina ezingqondweni izibopho ezinkulu eziphethwe yilo, likhuthaza ngamandla uMoya weDaqing kanye noMoya weNdoda Yensimbi, futhi liqoke ukuhlola nokuthuthukisa uwoyela we-shale waseGulong njenge-"Phrojekthi Enombolo 1." Ngokuhlanganisa izinsiza ezivela kulo lonke ifayili likawoyela ukubhekana nezinselelo ezibalulekile, likwazile ukuguqula le "ndawo engahlolwanga" ibe "indawo enokwenzeka" yokwandisa izinto ezigciniwe kanye nokukhiqizwa.

▲ Abasebenzi abavela Enyuvesi Yokulawula Umsebenzi Wokukhiqiza Uwoyela we-Shale Yesitshalo Sikawoyela SikaNombolo 9 benza ukuhlolwa endaweni eTest Zone 2 yendawo kawoyela we-shale eGulong.

Eminyakeni emihlanu edlule, iDaqing Oilfield izuze ukwanda okukhulu ekukhiqizeni uwoyela we-shale, kusuka ku-"zero" kuya ku-"1 million metric tons." Ngo-2020, umthombo iGuye Youping 1 wathola uwoyela. Ngo-2021, imithombo yokuhlola ebalulekile yaveza imiphumela ephezulu, lapho ukukhiqizwa konyaka kukashale oil kufinyelela ku-15,000 metric tons. Ngo-2022, imithombo eyi-58 eyi-horizontal wells ezindaweni ezinhlanu zokuthuthukisa izivivinyo yagqojwa ngokuphelele, futhi ubuchwepheshe bokufakelwa kwamanzi buvuselelwe. Ngo-2023, indawo eyandisiwe yokuhlola ukuthuthukiswa kweGuye 8H1 yaphumelela ukuhlanganisa ukwanda kwezinto ezilondoloziwe nokwakhiwa kwamandla okukhiqiza. Yonke imithombo engama-54 yasetshenziswa, nemiphumela idlula okulindelwe uhlelo. Kwasungulwa isibonelo sobuchwepheshe semithombo enomkhiqizo omkhulu, esiqondisa ngempumelelo ukuthuthukiswa okukhulu kwe-Q9 oil reservoir endaweni eyinhloko yokukhiqiza uwoyela ongagqinsi. Ukukhiqizwa konyaka kukashale oil kufinyelele ku-171,000 metric tons. Ngo-2024, kwasetshenziswa indlela yokuphatha "production mega-operation", kwabekwa amarekhodi amaningi: izinga lokungena ku-97% ezindaweni eziyinhloko, isikhathi esifushane kakhulu sokugqobhoza sezinsuku ezingu-9.63, ingxenye ende kakhulu eyi-horizontal section yamamitha angu-4,080, ukufakelwa kwamanzi okuningi ngosuku okuyizigaba eziyi-12, ukukhiqizwa kukashale oil okuphezulu ngosuku ngomthombo oyimitha cubic angu-102.0, kanye nokulingana kukashale oil negesi okungamathani angu-102.8 ngomthombo. Kulo nyaka, uMnyango Wezinsiza Zemvelo wahlole futhi wavuma izinto ezilondoloziwe eziqinisekisiwe eziyizigidi ezingu-158 zamathani we-shale oil kazwelonke iDaqing Gulong Terrestrial Shale Oil National Demonstration Zone. Ukukhiqizwa manje sekudlule izigidi ezingu-1 kumathani, kufeza ukuphindeka kabili unyaka nonyaka nokukhula okusheshayo kokukhiqiza.

Ukwenziwa kukagesi we-shale kufuna imishini ebalulekile yokususa isihlabathi njengama-desander.

Ukuhlanjululwa kwesihlabathi segesi ye-shalekuchaza inqubo yokususa izinto ezingcolile eziqinile njengezinhlamvu zesihlabathi, isihlabathi sokuhlukumeza (proppant), kanye nemfucumfucu yamatshe kusuka emifuleni yegesi ye-shale (ene-water ehambayo) ngezindlela zomzimba noma zemishini ngesikhathi sokukhipha nokukhiqiza igesi ye-shale.

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 izehlakalo zokuphepha ekukhiqizeni.

I-SAGA's shale gas desander iletha ukusebenza okukhethekile ngokukwazi kwayo ukuhlukanisa ngokunembayo (ukususa okungu-98% wezinhlayiya ezingama-micron angu-10), izitifiketi eziphethwe yiziphathimandla (isitifiketi se-ISO esikhishwe yi-DNV/GL kanye nokuhambisana ne-NACE anti-corrosion), kanye nokuqina okuhlala njalo (kuhlanganisa ingaphakathi le-ceramic elingamelana nokuguga eliklanyelwe ukungabambeki). Yakhelwe ukusebenza kahle kalula, inikeza ukufakwa okulula, ukusebenza nokugcinwa okulula, kanye nokuphila okwandisiwe kwensizakalo – okwenza kube 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 kwezobuchwepheshe obuhambisana nemvelo.

Ama-desander ethu aza ngezinhlobo ezahlukahlukene futhi anezicelo ezibanzi. Ngaphezu kwama-shale gas desanders, afana no-I-High-efficiency Cyclone Desander, I-Desander Ye-Wellhead, I-Desander Yokudonsa Okungaguquguquki Ye-Cyclonic Enama-Ceramic Liners, Ukujova amanzi iDesander，I-Natural Gas Desander, njll.

Ama-desander e-SAGA asele esetshenziswa kumapulatifomu e-wellhead namapulatifomu okukhiqiza emikhakheni kagesi namafutha afana ne-CNOOC, i-PetroChina, i-Malaysia Petronas, i-Indonesia, i-Gulf of Thailand, nabanye. Asetshenziselwa ukususa ama-solids egazini noma uketshezi oluvela emthonjeni noma amanzi akhiqizwayo, kanye nokususwa kokuqina kukasawoti noma ukubuyiselwa kokukhiqiza. Ukujova amanzi nokugeleza kwamanzi ukukhulisa ukukhiqiza nezinye izikhathi.

Le sikhulumi esihamba phambili siye sabeka i-SAGA njengomnikezi wesixazululo esaziwa emhlabeni wonke kwezobuchwepheshe bokulawula nokuphatha okungaguquguquki. Sihlala sibeka phambili izintshisekelo zamakhasimende ethu futhi siphishekela intuthuko ehlangene nabo.
