Abstract

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