“十四五”时期，中国首口超万米科探井完钻，成为亚洲第一、世界第二垂直深度井—— 掘进地下万米

Core Viewpoint - The successful completion of China's first 10,000-meter scientific exploration well, the Deep Earth Taka 1 Well, marks a significant milestone in deep earth engineering and oil and gas exploration, showcasing advancements in technology and geological understanding [9][13][18]. Group 1: Project Overview - The Deep Earth Taka 1 Well, located in the Tarim Basin, achieved a drilling depth of 10,910 meters, setting five global drilling records [9][12]. - This well is part of China's major deep earth engineering initiatives during the 14th Five-Year Plan period, aimed at enhancing national energy security [8][10][16]. Group 2: Technical Challenges - Drilling at such depths involves extreme conditions, including high temperatures (up to 220 degrees Celsius) and pressures (145 MPa), making it a formidable engineering challenge [12][14]. - The well had to penetrate 12 different geological layers, each with varying rock properties, necessitating frequent adjustments in drilling techniques and equipment [11][12]. Group 3: Technological Innovations - The project utilized a self-developed 12,000-meter automated drilling rig, capable of lifting 900 tons, significantly enhancing operational efficiency [14][15]. - Advanced drilling technologies, including high-temperature drilling fluids and specialized drill bits, were developed to meet the unique challenges of deep drilling [14][15]. Group 4: Geological Insights - The successful drilling provided valuable geological data from depths previously unexplored, confirming the potential for oil and gas resources in the Tarim Basin [13][17]. - The exploration of deep geological formations can reveal insights into ancient environmental conditions and the evolution of sedimentary basins [17][18]. Group 5: Strategic Importance - The advancement in deep drilling capabilities is crucial for China's energy strategy, as the country seeks to reduce its reliance on foreign oil and gas [16][18]. - The exploration of deep and ultra-deep oil and gas resources is identified as a key area for future discoveries, with significant remaining resources in the 8,000-meter and deeper categories [16][18].
