ABSTRACT:
The present invention relates generally to the use of polyaryletherketone-based thermoplastic materials in the fabrication of logging tools employed in high pressure, high temperature, downhole logging applications. A polyaryletherketone resin bonded with glass fibers is formed into a housing for the logging tool. The housing is constructed by any of the following processes: filament winding or compression molding. When used with a logging tool, the housing encloses the operative components of the logging tool, such as sensors and sources, and protects the operative components from borehole fluids.
