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.
