PROBE FOR ELECTRIC LOGGING Russian patent published in 2009 - IPC G01V3/00 

FIELD: physics, measurement.

SUBSTANCE: invention is related to the field of development geophysics and may be used for geophysical survey of oil and gas wells with standard instruments of lateral logging. Technical result is achieved by the fact that in probe for electric logging, which comprises steel electrodes in the form of nozzle rings, upper and lower connection devices, every of which includes body, connection wires, binding multi-contact sockets of upper and lower connection devices, according to invention, it additionally comprises protective jacket made of material with high electric resistance and heat and pressure resistance, for instance, glass fiber, on the surface of which electrodes are fixed coaxially, as well as bodies of upper and lower connection devices, and inside protective jacket detachable frame is fixed in body of upper connection device with the help of key and fixed in body of lower connection device with the help of nut, and in detachable frame connection wires are laid, and spring contacts are installed symmetrically to electrodes, at that current plugs are fixed on electrodes surface with the help of thread and sealing rings, and the plugs close spring contacts and electrically connect multi-contact socket of lower connection device to electrodes via connection wires.

EFFECT: increased accuracy of measurements and increased service life of equipment.
