Three-channel face apparatus for monitoring the direction of wells in the drilling process

Journal Article:

Abstract

Apparatus has been developed and successfully tested under laboratory and stand conditions for monitoring the direction of wells, using wireless communications channel on the string of drilling pipes. As a result of decrease in the frequency of the transmission signal, use of an LBT with best electrical characteristics, matching of the face transmitter with load and increase in the power of the transmitter, a level of useful signal 30 m V is successfully obtained on the surface from depth 2500 m in high-ohmic sections and 10 mV from depth 1900 m in low-ohmic sections.
