结合近年来的科研和生产实践 ,以及海洋石油的钻井现状 ,讨论了国内外对于水平井、大斜度定向井摩擦阻力研究的现状及发展趋势 ,详细介绍了钻井摩阻问题的产生及研究背景。系统地给出了我国近十几年来研究钻井摩阻问题的科研成果 ,并扼要叙述了这些成果在生产实践中的应用。作者还着重介绍了我国国家“863”高科技发展计划中唯一的一个石油项目———海洋大位移石油钻井技术中的水平井摩阻技术的研究与应用 ,并结合一系列与国外同行的交流与技术合作 ,提出钻井摩阻技术已是我国为数不多的几项具有中国特色的石油前沿技术之一。
Combining with the research and production practice in recent years and the status quo of offshore drilling, the status quo and development trend of frictional resistance research on horizontal well and high-gradient directional well at home and abroad are discussed. The generation and research background of drilling friction problems are introduced in detail . The scientific research results of drilling friction problems in China in recent ten years are given systematically and the application of these achievements in production practice is briefly described. The author also focuses on the research and application of the horizontal well frictional resistance technology in the large displacement offshore oil drilling technology, the only oil project in the “863” high-tech development plan of our country, combining with a series of exchanges with foreign counterparts With technical cooperation, it is proposed that drilling friction technology is one of the few petroleum frontier technologies with Chinese characteristics in our country.
