对我国陆上过去 50年钻井科学技术的发展作了概要回顾 ,总结了 6个方面进展 ,得到了 3条对进展的总体评价意见和 4条基本经验 ,认为要坚持走自主研究开发与有选择地吸收国外先进技术相结合的科技发展道路 ,并力争提高自主创新的比重。在分析过去 50年世界钻井技术发展过程的基础上 ,认为 2 1世纪钻井技术发展的主导趋势是实现钻井的自动化与智能化。根据钻井科技发展的主导趋势 ,结合我国钻井当前面对的严峻局面 ,提出了近期需要研究攻关的 5个课题 ,供有关部门参考。 This paper reviews the development of drilling science and technology over the past 50 years in China, summarizes the progress in six aspects, obtains three general comments on progress and four basic experiences, and believes that we should stick to the independent research and development and the choice To absorb the combination of advanced foreign technology development path of science and technology, and strive to increase the proportion of independent innovation. Based on the analysis of the development of drilling technology in the world over the past 50 years, it is considered that the predominant trend of drilling technology development in the 21st century is to realize drilling automation and intelligence. According to the dominant trend of drilling technology development, combined with the current grim situation facing drilling in our country, we put forward five topics that need to be studied in the near future for the reference of relevant departments.
