SEALING ASSEMBLY OF PROBE FOR ELECTRIC LOGGING AND PROBE COMPRISING SEALING ASSEMBLY Russian patent published in 2020 - IPC G01V3/18 

FIELD: mining.

SUBSTANCE: invention relates to equipment for investigation of wells, in particular to probes for electric well logging, and more specifically to sealing assembly of probe, providing tightness of electric equipment placed in housing of probe, from action of environment of well. Essence: sealing assembly of probe for electric logging contains cylindrical housing, at least two dielectric bushings installed on housing, at least one ring-shaped electrode, coaxially arranged on housing between dielectric bushes and contacting by its end surfaces with end surfaces of dielectric bushes, insulating facility arranged on cylindrical housing, means of pressing force and fixation. Each of at least one ring-shaped electrode and at least two dielectric bushings in contact with ring-shaped electrode has curvilinear end surfaces. Curved end surfaces of electrode are conjugated with curvilinear end surfaces of dielectric sleeves contacting with it.

EFFECT: technical result is improved tightness and elimination of damages of electrical equipment of probe, increased flexibility of probe and safety of logging instruments in wells, elimination of deformations of ring-shaped electrodes and dielectric bushings.
