V nedavnih letih, Kitajska je dosegla izjemen napredek v raziskavah celinskih skrilavci nafti pridobivanju tehnologijah, in skrilavcu nafti proizvodnji v 2024 bo dosegla več kot 6 milijon ton. Vendar, za popolno doseči cilje skrilavca nafte revolucije še vedno sooči mnogi izzivi, in to je izredno ključna za ponovna - razumeti značilnosti Kitajske's kontinentalna skrilavca nafta.
The exploration and development of China's continental shale oil has gone through multiple stages, from the discovery of fractured reservoirs in shale intervals and concurrent exploration with "conventional oil", to the exploration of "unconventional shale oil", then to targeted technological research and a new round of evaluation and deployment, etc. Domestic scholars have attached importance to the comparative study with the geological conditions of marine shale oil in the United States from the very beginning, but found that simply comparing based on parameters such as sedimentary environment, burial depth and lithological characteristics cannot fully reflect the differences in geological conditions. The high - yield example of Vaca Muerta shale oil in the Neuquén Basin in Argentina shows that the highest - yield layer is located in the shale layer with high TOC, and the gas - to - oil ratio in the latest high - yield area is only 12 cubic meters per cubic meter, and the API gravity is 25; in the Jiyang Depression in the Bohai Bay Basin, the exploration of medium - low - maturity shale oil has also achieved good results. This indicates that maturity, crude oil density and gas - to - oil ratio are not decisive factors, and it is necessary to re - understand the geological characteristics of China's continental shale oil based on the actual domestic exploration results, so as to promote technological innovation and technological iteration.
Na tehnološki ravni% 2c domačih podjetjih so organizirala več preiskav na skrilavcu nafti in plinu razvoju tehnologijah v Združenih državah Amerike % 2c in ugotovila da Kitajska še vedno ima prostor za izboljšanje v vrtanju in lomljenju učinkovitosti% 2c enojna - vrtina EUR in kilometer - vrtina gradnja stroški% 2c itd. Medtem, upad v skrilavcu nafti vrtini proizvodnji je cilj zakon, horizontalno vrtine in visoki - donos vrtine samo račun za a majhno število, in večina vrtin so nizko - donos vrtine, ki ki ne morejo biti prezrti. Zato, to to je potrebno za nadaljnjo okrepiti zaupanje in sprejeti več aktivni ukrepi v smislu deljenja teoretičnih in tehnoloških dosežki, podatki izmenjava in umetna inteligenca aplikacija.
China has established multiple national - level continental shale oil demonstration areas, such as the Jimusar National - level Continental Shale Oil Demonstration Area in Xinjiang, the Daqing Gulong National - level Continental Shale Oil Demonstration Area and the Shengli Jiyang Continental Rift - lake Basin Shale Oil National - level Demonstration Area. These demonstration areas have achieved strategic breakthroughs in technological research. We should further promote mature technologies and experiences, and make greater breakthroughs in Sichuan, Qaidam and other small - and medium - sized basins to achieve the goals of increasing reserves and production. Meanwhile, we should actively explore new technologies for enhancing recovery rate throughout the life cycle, and on the basis of existing conventional technologies such as gas injection for enhanced recovery and chemical flooding for enhanced recovery, explore innovative new technologies such as thermal enhanced recovery, nanomaterial - based enhanced recovery and "temperature, pressure, wind, solar and energy storage" - coordinated green shale oil mining, so as to significantly reduce costs and lay a solid foundation for large - scale on - site implementation and application. It is especially necessary to point out that it is very important to explore new paths for in - situ conversion technologies of medium - low - maturity shale oil. PetroChina is conducting a pilot test for in - situ conversion of shale oil in the Chang 73 section of the Ordos Basin. If the test is successful, it is expected to enter the commercial development demonstration stage.
Medtem, aktivno raziskujemo nove tehnologije kot so v - situ nadgradnja z superkritično ogljik dioksid, zagotavljanje več možnosti za učinkovito razvoj srednje - nizko - zrelost skrilavec nafta. V zaključek, promocija tehnološka inovacija je ključ ključ za raziskovanje pot Kitajska - slog skrilavec nafta revolucija. Morali bi v celoti razumeti značilnosti Kitajske's celinske skrilavce nafte, nenehno izboljševati tehnološko raven, okrepiti gradnjo demonstracijskih področij, in aktivno raziskovati nove tehnologije, tako kot prispevati veliki - obseg skrilavca nafta razvoj in promocija Kitajske's energija transformacija.
