On November 9th, PetroChina Changqing Oilfield officially announced that the cumulative production of shale oil has exceeded 20 million tons.coupings This milestone achievement marks the successful transition of China's onshore shale oil development from the exploration and testing stage to a new stage of scale and efficiency development, laying an important support for national energy security.coupings As an important core area for shale oil production in China, Changqing Oilfield is rooted in the Ordos Basin. This hot soil, which contains over 1 billion tons of shale oil reserves,coupings has witnessed the 15 year struggle of Sinopec. coupings From the initial technological exploration to the cumulative production exceeding 10 million tons, Changqing Oilfield took 12 years to overcome the world-class challenge of continental shale oil development under complex geological conditions like a sharpening stone. coupings The leap from 10 million tons to 20 million tons was successfully achieved in just three years, driven by both technological innovation and management upgrading.coupings For many years, Changqing Oilfield has adhered to independent innovation,coupings established the theory of source reservoir symbiosis and enrichment of shale formations in terrestrial freshwater lake basins, integrated and innovated 22 supporting technologies in five major technology series,coupings independently developed 12 key core technologies, and successfully broke the foreign technology monopoly. coupings The mature application of horizontal well drilling, volume fracturing and other technologies enables the drill bit to achieve "precise underground navigation", coupings effectively solving the dilemma of small gaps and difficult exploitation in shale oil reservoirs. At the same time, the combination of the "large well cluster, coupings multi-layer system" well layout mode and the digital unmanned management system has achieved intensive development of "less land occupation and more oil production", significantly reducing the labor demand for millions of tons of production capacity and continuously improving per capita labor efficiency. This breakthrough in production not only demonstrates the responsibility of Changqing Oilfield as a "major player",coupings but also forms a replicable and promotable set of practical experience for large-scale development of terrestrial shale oil. coupings At present, the daily production of shale oil in Changqing Oilfield has exceeded 10000 tons, accounting for more than half of the total shale oil production in China. It is expected that the production will exceed 3.5 million tons by the end of the year and reach 4.5 million tons by 2030. Against the backdrop of high external energy dependence,coupings the exploration of Changqing Oilfield provides a solid foundation for improving domestic energy self-sufficiency and responding to fluctuations in the international energy market.coupings It also paves the way for high-quality development of unconventional oil and gas resources in China, emphasizing both scale and efficiency, and achieving a win-win situation between development and ecology.coupings
