Abstract

Mud pulse telemetry (MPT) transmits data from borehole to surface during the drilling process. Pressure wave is generated in the drilling channel and is used as carrier of the downhole data. Through numerical simulation, this paper analyzes the bit error rate (BER) of mud pulse telemetry under different signal to noise ratio (SNR) based on on-off keying (OOK) modulation scheme. By observing the effect of waveform error on BER, the allowed variation ranges in signal amplitude and period are obtained.
