FIELD: oil and gas industry.
SUBSTANCE: method is suggested to perform measurements in the well that contains the following stages: actuation control for the device placed in the well and having assembly of radiating and receiving antennas placed at distance and capable of operation in selected pairs of radiator and receiver. At that deep-earth signal is recorded from deep-earth measurement using a pair of radiator and receiver, and one or several shallow-earth signals are recorded using one or several other pairs of radiator and receiver; one or several shallow-earth signals are processed, a model signal is generated in regard to areas joining side walls and rear side of the device; and forward-scanning signal is generated in essence without contribution from the areas joining the device by means of deep-earth signal processing depending on the model signal. The invention also suggests a device for measurements in the well and machine-readable memory unit with instructions to perform actions in the above method.
EFFECT: improved sensitivity and data accuracy in process of measurements in the well.
