METHOD AND APPARATUS FOR MEASURING DEFORMATION OF NON-METALLIC MATERIALS

摘要

A method for measuring the deformation of elastomeric materials usingacoustic signals involves obtaining a sample, positioning the sample in asealablechamber, sealing the chamber, and setting a temperature and pressure insidethechamber. A test fluid may be introduced to the chamber. An acoustic signal isusedto measure a characteristic of the sample, such as a dimension or a modulus.Repeated measurements may be made overtime to monitor changes in the samplein response to temperature and pressure. The acoustic signal may be generatedbyan acoustic transducer including a backing component including a fluorine-containing polymer in which metal particles are incorporated. The sample maybe anon-metallic material. Conditions inside the chamber may be set to simulate awellbore environment.
