FIELD: oil and gas industry.
SUBSTANCE: system for recognizing the pipes connection inside the wellbore structure contains the device, connected with the well structure in line. The device has the central end-to-end channel. It contains the plurality of the blind holes, going radially inward from the outer surface. The system additionally contains at least one ferromagnetic device, located inside one of several blind holes. Each of the ferromagnetic devices has the magnet at its end, and at least one sensor, positioned inside one of at least one sleeve. At least one sensor, connected to the mentioned at least one ferromagnetic device. At that the mentioned sensor is configured to issue the signal, representing the width of the metal object, located within the central channel. The system may also contain the display, configured to receive the output signal from at least one sensor and display for the output signal user, indicating the width of the metal object in the centre channel.
EFFECT: improved recognizing accuracy.
