摘要:

针对深层超深层钻井技术,系统论述了国内外目前的研究现状及进展,分析深层超深层钻井技术面临的挑战,并提出未来发展方向。随着油气资源开发向深层和超深层推进,钻井技术面临高温高压、复杂地质构造、井壁稳定性等诸多难题。近年来,在井身结构优化、超深井钻机装备、钻井液技术等方面取得了显著进展,但仍存在抗高温高压能力不足、井壁易失稳、钻井液漏失严重等关键问题。未来,井身结构优化技术将朝着智能化、精细化方向发展,进一步提升风险预警精度和井身结构设计的动态调整能力;钻机装备和关键工具将聚焦自动化、智能化升级和提升工具的耐温、承压和可靠性;钻井液技术则需在抗高温高盐水基和油基体系以及防漏堵漏等方面进一步攻关。这些技术突破将为深层油气资源的高效开发提供坚实支撑。

Abstract:

This paper systematically discusses the research progress of the deep and ultra-deep drilling technology in both China and other countries,analyzes the challenges faced by the deep and ultra-deep drilling technology,and points out the future development direction. With the exploitation of hydrocarbon resources shifting toward deep and ultra-deep formations,drilling technology faces many challenges,such as high temperature and high pressure (HTHP),complex geological structure,and wellbore instability. In recent years,significant progress has been made in the casing program optimization,ultra-deep drilling rig equipment,drilling fluid technology,etc.,but there are still vital problems,such as HTHP tolerance,wellbore instability and severe lost circulation. The future development of the casing program optimization technology is oriented toward intelligence and refinement to improve the risk warning accuracy and the dynamic adjustment ability of the casing program design. The rig equipment and key tools will focus on automation and intelligent upgrading to improve their tolerance of temperature and pressure and reliability. The drilling fluid technology needs to be further studied in terms of water- and oil- based drilling fluid systems tolerant of high temperature and high salinity and lost circulation control and plugging. These technological breakthroughs are expected to provide solid support for the efficient development of deep oil and gas resources.
