DOWNHOLE OIL WELL SENSOR HOUSING HAVING A COMPRESSION SEAL ASSEMBLY

摘要

The invention relates generally to a downhole oil well sensor housing having a compression sealing assembly that is responsive to the external pressures within a subterranean bore-hole. The downhole oil well sensor housing has a sealing assembly configured to provide a compression seal around individual signal wires coupled to a downhole measurement sensor retained within the sensor housing. The downhole measurement sensor is secured within one end of the sensor housing, while the sealing assembly is secured within the opposing end of the sensor housing.

主权项

1. A sensor housing, comprising:
a sensor housing body comprising an internal passage with opposed ends, at least one of said ends comprising a recess defined within an inner periphery of said sensor housing body; and a sealing assembly configured to provide a compression seal in response to external pressure applied to said sensor housing body, said sealing assembly comprising:
an end plate having a medial face and a distal face, said medial face of said end plate configured to engage said recess, said end plate comprising a housing seal groove defined on an outer periphery of said end plate, said end plate comprising an internal bore having a distal end terminating with a wire seal groove;a housing seal assembly in sealing engagement with said housing seal groove of said end plate and said recess of said sensor housing body;a wire seal assembly disposed within said wire seal groove of said end plate; anda retaining disc disposed within said sensor housing body and in contact with said distal face of said end plate, said retaining disc comprising an internal bore coaxially aligned with and axially spaced from said internal bore of said end plate.
