Behavioral Modeling a Wireless Borehole Communication Channel for Increase of the Telemetry Transfer Accuracy

P. 1-5.
Stukach O., Mirmanov A.

We describe a procedure of compact behavioral models design of the communication channel through a borehole pipe for measurement while drilling (MWD) microwave systems based on results of measurements of radio pulse signals during testing of the channel. Characterization of the microwave channel for the decline-directed borehole and a transmitter on the Gunn diode is described as an example of the offered process. The procedure is based on measurement of signal samples of the transmitter with the subsequent accounting of electrodynamical parameters, attenuation in the media, and on the pipe walls.We describe a procedure of compact behavioral models design of the communication channel through a borehole pipe for measurement while drilling (MWD) microwave systems based on results of measurements of radio pulse signals during testing of the channel.
