FIELD: oil and gas industry.
SUBSTANCE: device for determining azimuth angle of well deviation includes frame with eccentric load, in which there arranged is magnetic arrow, panel with turning angle converter and power supply in the form of compressed gas bottle. Turning angle converter is connected to communication channel and made in the form of fluid oscillator consisting of feed nozzle, outlet and inlet nozzles and receiving capacity, which are connected to each other by means of commutation channels. Output of power supply is connected to feed nozzle through the controlled reduction gear. In addition, device is equipped with mechanical resonator, actuator system, rheochord on the coils of which magnetic arrow is caged, and electric power supply. At that, free end of resonator is arranged in jet stick zone at the receiving nozzle inlet.
EFFECT: improving reliability and accuracy of measurement of azimuth angle of well deviation.
