MULTIPOLE SONDE OF LATERAL LOGGING Russian patent published in 2017 - IPC G01V3/18 E21B47/00 

FIELD: electricity.

SUBSTANCE: each of the multipole sonde electrode of the lateral logging is equipped with at least three cylindrical current collecting contacts, uniformly spaced relative to one another along the housing circle. At that each of the current removable contacts is mounted in the housing body with ability of limited stroke perpendicularly to the longitudinal axis of the latter and resting into the elastic conductive plate, performed as an oval spring fixed on the chassis in front of each current removable contacts landing areas. At the inner circular surface of each electrode and each cylindrical insulator recesses-grooves are performed, in which the sealing rings are placed, and bevels of the mating end surfaces of the electrodes and insulators are made at the angle, at which the insulator end surface completely covers the mating with it the electrode end surface or the pressure unit end surface.

EFFECT: improved accuracy of investigated parameters measurement and reliability of multipole sonde of lateral logging.
