PROBE FOR ELECTRIC LOGGING Russian patent published in 1996 - IPC

FIELD: gas and oil industry. SUBSTANCE: probe is designed for geophysical research in oil and gas wells. Probe includes electrodes, upper and lower connectors, suspension, connecting wires and protective hose. Each connector incorporates case with electric lead-in, multipin connector assembly and protective cap joined to case with the aid of thread. Suspension is manufactured in the form of flexible cable made of synthetics which ends form loops and are anchored inside protective caps of connectors with the help of eyelet. Electric leads-in are fabricated in the form of conical insulators with current conductive rod inside installed in cases diameter positioned coaxially with ends being fixed in butt recesses of protective caps and electrodes. Free space inside protective caps, electrodes and protective hose is filled with high- resistance material, for instance, oligomer. EFFECT: increased electric insulation of probe, simplified design of electric leads-in and suspension which enhances in its turn measurement precision and operational reliability of equipment in which probe is used. 2 cl, 1 dwg
