Measurement While Drilling system has been more and more widely used in directional drilling construction on the surface of mines. The system provides guidance for drilling construction, because it can transmit drilling parameter signals such as the deviation angle, azimuth and tool face angle collected by downhole tools to the ground through the mud, and then the signals are analyzed and decoded by computer software to restore the actual parameter data. In drilling construction, the self-developed BJZM-MWD1 Measurement While Drilling system encountered problems such as great variation in the amplitude and width of mud pulse signals and the interference of pulse signals. By filtering and amplifying the mud pressure generated by the pulse signal, and improving software decoding algorithm, the stability and reliability of the system have been greatly improved, meeting the requirements in site construction.
