HTHP In-situ Mechanical Test Rig and Test Method for High-temperature Polymers and Composites (SPE-113516)

摘要

High-temperature polymers and their composites have been used extensively in critical industrial applications, including composite drill pipes, tubing and casing, logging tools, and various drillable tools for oilfield downhole operations. However, when a wet condition is combined with high temperature, most high-temperature polymers and their composites behave very differently from their original dry state because of severe hygrothermal or hydrolytic degradation. In many cases, oilfield service tools are required to perform in a hot-wet fluid condition at temperatures above 204oC and pressures above 70 MPa. These conditions present significant challenges to applications of polymers and composites. Properly characterizing and fully understanding the HTHP hot-wet thermomechanical properties of various high- temperature polymers and composites based on an accurate, environmentally simulated HTHP mechanical test method is extremely important for successful applications.
