GV-MWD System (Wireless Measurement-While-Driling System)

 Wireless measurement-while-drilling system (MWD) is a specialized steering tool during drilling. Data received by the downhole hypogynous device is processed and encoded in a special format and embedded within a pulse signal generated by a pulse generator. This signal is sent to the surface though drilling mud and can be received thousands of meters away. Wave signals propagating in drillmud are obtained by the pressure sendor at well head and send to surface DIB box. Thus, the signals are transformed, filtered and other processing actions performed upon them by the surface epistatic device. The sueface epstatic device performs digital filering, decoding, computerization and other processing before the processed downhole parameters are provided for drilling engineers to to monitor and track well drilling and logging.
