Abstract:
1. A high-temperature, high-pressure standoff for providing a fluid-tight seal for an electrical connection in a well between an electrical conductor extending from down hole of the well and a power source conductor extending from an above-ground power source enclosed by and extending through and further into the wellbore in a rigid tube surrounding an electrical conductor and an insulating sheath over said electrical conductor terminating in a rubber boot surrounding the rigid tube, the power source conductor extending down hole to a connector socket for connecting the power source conductor to another electrical conductor, tie high-temperature, high-pressure standoff within said connector comprising: an electrically resistive metal sleeve having a first inner surface having an inner diameter permitting the rigid tube to be inserted therein and a second inner surface having an inner diameter permitting the electrical conductor and an insulating sheath to be inserted therein and an inner shoulder between said first and second inner surfaces having a width approximating the width of the rigid tub to seat an end of the rigid tube; an electrically insulative tubular body having a hole forming an inner surface surrounding the power source conductor between the lower end of the rigid tube and the connector, the rubber boot coaxially surrounding the tubular body and conductor; and, an electrically resistive washer intermediate the end of the tubular body and insulating sheath and a conductor socket for connecting the conductor.
