FIELD: measuring equipment.
SUBSTANCE: system contains a number of transmitting sensors, a number of receinving sensors located on the structure of the device as well as a control unit. The number of transmitting sensors contains one or more multi-pole transmitter sensors. The location of one or more multi-pole transmitter sensors is such that each multi-pole transmitter sensor is in a different angular position around the circumference of the device structure. The number of receiving sensors contains one or more multi-pole receiver sensors and is configured to receive a signal in response to the selective activation of the number of transmitting sensors. The location of one or more multi-pole receiver sensors is such that each multi-pole receiver sensor is in a different angular position around the circumference of the device structure. One or more multi-pole transmitter sensors and one or more multi-pole receiver sensors provide deep azimuthal sensitivity of high order during system operation. The control unit controls the selective activation of the number of transmitting sensors and selectively receiving signals from the number of receiving sensors in response to selective activation.
EFFECT: possibility of improving the evaluation of reservoirs.
