Abstract
The present invention relates to a method and to a system for analyzing drilling conditions and/or the behaviour of a drill string element. It comprises the stages as follows: PA1 acquisition of a signal, PA1 calculation means are operated, which determine the wavelet coefficients of segments of the signal, the segments are merged to form a homogeneous segment, PA1 a magnitude associated with each homogeneous segment is determined. The invention further relates to a system for implementing the method.
