FIELD: oil and gas industry.
SUBSTANCE: device is composed of the following components: main and directional units of gamma-ray logging sensors installed in MWD casing. The directional unit of gamma-ray logging sensors is placed into a lead case with a window to register directional gamma-ray emission which is interrelated physically with a deflector position. The units of gamma-ray logging sensors are placed into a measuring gamma-module with a wire communication channel and MWD unit and are equipped with an electronic circuit for MWD signals matching with pulses of gamma-ray logging sensors.
EFFECT: improving accuracy of gamma quantum registration, simplifying the design and optimisation of control efficiency during horizontal and directional sidetracking.
