    摘要:

    特深井大陆科学钻探是揭示地球深部物质组成、构造演化与资源潜力的关键途径,岩心是解读地层信息的第一手实物证据。绳索取心作为高效获取岩心的核心技术,直接决定取心质量与钻探效率。然而,超万米钻探受超高温、超高压、高应力与复杂地层的共同作用,易造成钻头寿命缩短、密封失效、岩心卡堵、丢心风险加剧,同时还存在钻杆强重比差、孔壁摩阻大、井底动力钻具输出扭矩不足、送钻精度低等诸多难题。本文系统综述了绳索取心技术的挑战、进展与趋势,剖析了深部极端工况下取心钻具、钻柱、动力钻具、垂钻系统、随钻测井系统及动态测试平台等方面的技术瓶颈,总结了国内外在这些领域的最新进展。结果表明,尽管各项关键技术已取得重要突破,但仍亟待解决材料在极端环境下的适应性、井下密封传动可靠性及智能测控协同等问题。未来需依托多学科交叉融合创新,重点攻关可耐受300 ℃、175 MPa工况的钻具材料,推进智能取心钻头、耐高温机械式垂钻与取心工艺的智能化融合,构建多场耦合动态测试与评价标准体系,实现从传统取心技术向智能绳索取心技术的战略升级,为万米级科学钻探提供坚实的技术保障。

    Abstract:

    Continental scientific drilling in ultra-deep wells is a crucial approach to revealing the deep Earth''s material composition, tectonic evolution, and resource potential, and cores serve as the first-hand physical evidence for interpreting stratigraphic information. As the core technology for highly efficient core acquisition, wireline coring directly determines coring quality and drilling efficiency. However, drilling beyond 10,000 meters, subjected to the combined effects of ultra-high temperature, ultra-high pressure, high stress, and complex formations, is prone to causing shortened bit life, seal failures, core jamming, and an increased risk of core loss. Meanwhile, numerous challenges persist, such as the poor strength-to-weight ratio of drill pipes, high wellbore friction, insufficient output torque of downhole motors, and low feed delivery accuracy. This paper systematically reviews the challenges, advances, and trends of wireline coring technology. It analyzes the technical bottlenecks of coring tools, drill strings, downhole motors, vertical drilling systems, logging-while-drilling (LWD) systems, and dynamic testing platforms under deep extreme working conditions, and summarizes the latest global advances in these fields. The results indicate that although significant breakthroughs have been made in various key technologies, urgent issues still remain to be resolved, including the adaptability of materials to extreme environments, downhole sealing and transmission reliability, and intelligent measurement and control synergy. Future development should rely on multidisciplinary cross-integration and innovation, focusing on developing drilling tool materials capable of withstanding 300 ℃ and 175 MPa, promoting the intelligent integration of smart coring bits, high-temperature-resistant mechanical vertical drilling systems, and coring processes, and constructing a multi-field coupled dynamic testing and evaluation standard system. This will achieve a strategic upgrade from traditional coring technology to intelligent wireline coring technology, providing a solid technical guarantee for 10,000-meter-level scientific drilling projects.
