Method of measuring vibratory condition of a drill string

Abstract

The article discusses issues related to the improvement of the operational reliability of downhole measurement systems. The circumstances of insufficient readings accuracy due to severe operating conditions are shown. The inherent negative factors are given, which jointly affect the reliability of the systems and measuring instruments in use. In particular, special attention is paid to vibration loads and the need for their measurement. The urgency of development and research of new reliable systems is demonstrated. A developed method for measuring the vibratory condition of a drill stem and a developed device for the implementation of this method are presented, and operation of the latter is analyzed.
