CA 2736398

Downhole tools are provided for measuring the inclination of a portion of a drill string. In certain embodiments, downhole tools for measuring inclination comprise a catch system for measuring inclination and a pressure pulse signaling system for communicating inclination measurement information to the surface. Catch systems for measuring inclination include a series of disc mounted on an upper shaft, each disc having a ball disposed thereon.

L'invention concerne des outils de fond permettant de mesurer l'inclinaison d'une partie d'un train de tiges de forage. Dans certains modes de réalisation, les outils de fond permettant de mesurer l'inclinaison comportent un système de capture pour mesurer l'inclinaison et un système de signalisation à impulsions à pression pour communiquer les informations de mesure d'inclinaison à la surface. Les systèmes de capture permettant de mesurer l'inclinaison comprennent une série de disques montés sur un arbre supérieur, chaque disque ayant une bille disposée sur celui-ci.
