INSTRUMENT SYSTEM FOR A DRILLING UNIT

摘要

This invention discloses an instrument package 20 for a drilling a unit which gathers the information from a pitch sensing device 52, a roll sensing device 53, and a 3-position magnetometer 51 along with a gamma counter 50, and converts the information to a multiplexed signal which is subsequently used to frequency modulate a pulse train. The pulse train is then transmitted down a long cable to a receiving apparatus 37 where the pulse train is processed by a microprocessor which demultiplexes the information, computes the roll, pitch, azimuth and gamma count and displays the computed results on appropriate visual indicators 38 to 41. The operator can, from the displayed data, operate the drill in accordance with conventional procedures. IMAGE
