钻柱振动信息测量技术研究进展

PROGRESS IN MEASUREMENT TECHNOLOGY FOR DRILL STRING VIBRATION

  • 摘要: 随着深井、超深井数量的快速增加, 钻柱振动导致的钻具失效问题更加突出. 针对钻柱振动的研究可分为理论与数值模拟、测量分析两种方法. 由于钻柱振动具有复杂的非线性特征, 使得理论与数值模拟研究受到了很大限制, 因此井下振动测量技术的研究显得尤为重要. 本文比较全面和系统地介绍了国内外钻柱振动测量技术研究现状和进展情况, 并对几个应用较为成熟的国外测量系统的工作原理、分析方法及应用技术进行了详细的综述. 所得结论可为我国井下振动测量技术的发展提供重要参考.

     

    Abstract: The drill string fatigue failure caused by drill string vibration is increasingly an issue related with the development of ultra-deep drilling operations. The research methods of drill string vibration can be classified into two types, the theoretical analysis or numerical simulation, and the the measurement technology. Owing to various complicated nonlinear mechanical problems, especially, the impact between moving drilling tools and hole wall, it is dificult to study the drill string vibration in many cases using the theoretical analysis or numerical simulation method, and therefore, the down hole vibration measurement technology becomes more and more important. This paper gives a comprehensive and systematic review of the status and progress of drill string vibration measurement technology, followed by a detailed discussion of the working mechanism, analytical approach and application technology for several overseas measurement tools which have been widely used around the world. The results would provide important supports to develop the down hole vibration measurement technology in our country.
