Abstract
The problem of telemetry information transmitting requires a comprehensive study of new communication channels and finding transparency windows for wave propagation in the operating frequency band. Electromagnetic communication channels are energy inefficient and have a low data transfer rate. Cable communication channels have high maintenance costs, and telemetry transmission is impossible at large depths. This paper provides a brief overview of the methods of telemetry information transmitting. The outcomes of the design of a receiving and transmitting ultrasonic device for telemetric information transmitting are presented. The receiver and transmitter are based on the piezo-emitter ZP-25. The frequency of the transmitted signal is 40 kHz. An experimental installation simulating a part of a producing well was used to study the acoustic signal propagation. As a result, a linear regression model of acoustic signal attenuation in the well was received. A comparison is made with the theoretical model of acoustic signal propagation. The discrepancy between the obtained and theoretical model is found. It is shown that linear regression is consistent with experimental results, it is a good simulation model for the signal transmission process, and nonlinear effects in the frequency band under consideration are insignificant. Also, the experimental model has much less attenuation compared to the theoretical one.
