Use of polyaryletherketone-type thermoplastics in downhole tools

摘要

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 (50). The housing (64) 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 (62) and sources (60), and protects the operative components from borehole fluids.
