Abstract

Targeting the difficulties of mud pulse signal Previous HitidentificationNext Hit in the process of measuring while drilling (MWD), and based on the analysis of the generation principle of mud pulse signal and the noise characteristics, a mud pulse signal Previous HitidentificationNext Hit method based on credibility analysis was established by means of studying the signal waveform characteristic attributes and signal similarity. The prototype of a mud pulse signal Previous HitidentificationNext Hit Previous HitsystemNext Hit designed according to this method enables a flexible interactive control. It also does a dynamic parameter adjustment and real-time visualization of processing process, and has achieved good effects in field application of MWD. With a good adaptability, such method can identify the real signal waveforms in a complex field environment accurately and intelligently to provide technical support for smooth MWD operations.
