Zhong Guo Hua Gong Bao·2025-10-17 03:43Core Insights - China's first national-level continental shale oil demonstration zone, the Xinjiang Jimusaer shale oil project, has achieved a cumulative production of over 5 million tons, laying a solid foundation for the successful completion of the demonstration zone construction goals for this year [1] Production and Technology Development - The shale oil reservoir in Jimusaer is buried over 3,800 meters deep, with a permeability only one ten-thousandth of that of conventional oil reservoirs, making extraction extremely challenging [1] - The demonstration zone has established over 40 industry standards and a comprehensive technical system for continental shale oil, innovating a sweet spot evaluation system centered on "movable oil" [1] - Key technologies such as "golden target identification" and "wide-area support fracturing" have been developed, increasing the single well's total life cycle output from 25,000 tons to 35,000 tons [1] Efficiency Improvements - The efficient production model of "drilling-fracturing-oil extraction" has been summarized, leading to enhanced drilling and fracturing efficiency [1] - In 2023, the Jimusaer shale oil demonstration zone has accelerated capacity construction, completing 48 wells, with the "golden target" drilling success rate increasing from 44% to 89% [1] - The average completion cycle has been shortened to 31.7 days, a 5% year-on-year reduction [1] - As of now, the demonstration zone has produced 1.35 million tons of shale oil this year, achieving 79% of the annual production target [1]
