摘　　要：随着深井、超深井以及特殊工艺井越来越多,对钻井液性能的要求也越来越高。为满足安全、快速、高效钻井需要,国内在钻井液开发与应用方面开展了大量研究与应用,并不同程度地满足了钻井工程的需要。尤其是,在抑制性钻井液、油基钻井液、超高温超高密度钻井液等方面取得了快速发展,形成了一系列实用的钻井液技术,逐步缩小了与国外的差距,特别是超高密度钻井液技术已居于国际领先地位。为了更清楚、更全面地了解近年来国内钻井液技术的发展情况,为国内钻井液的开发与应用提出有价值的建议,从抑制性和环保型钻井液、油基钻井液、超高温超高密度钻井液、泡沫钻井液和合成基钻井液等方面,对钻井液的开发、性能和应用情况进行了介绍,在此基础上分析了国内钻井液存在的问题和发展方向,并结合钻井实践,提出了未来需要重点开展的工作。研究结果对国内钻井液的开发与应用具有参考价值和指导意义。Along with the continually increasing deep wells, ultra-deep wells and special process wells, higher standards were imposed on drilling fluids to meet the needs of safe, fast and efficient drilling. To evaluate the progress on the development of high-performance drilling fluids a great deal of research and test applications were carried out over the research and development of drilling fluids that satisfy the particular needs of drilling engineering in China. In particular, rapid development has been achieved in aspects of inhibitive drilling fluids, oil-based drilling fluids, ultrahigh temperature and ultra-high density drilling fluids, etc., and a series of practical drilling fluid technologies were formed. They have gradually narrowed the gap with foreign counterparts, especially with respect to the ultra-high density drilling fluid technology of China which plays a leading role in the world. In order to better understand the new development of domestic drilling fluid technologies, and provide valuable suggestions for the development and application of drilling fluids in China, this paper introduces the development, performance and application of drilling fluids. The study focused on the characteristics of inhibitive/environment friendly drilling fluids, oil-based drilling fluid, ultrahigh temperature and ultra-high density drilling fluids, foamed drilling fluid and synthetic-based drilling fluid. The study includes a comprehensive review of the problems and development trends of drilling fluid in China, and proposes the tasks that need to be carried out in the future in combination with drilling practices. The research results constitute and excellent reference and best practices for the development and application of domestic drilling fluids.
