ULTRASONIC IMPACT TREATMENT FOR USEFUL LIFE IMPROVEMENT OF DOWNHOLE TOOLS

摘要

The useful life of a downhole tool is improved through application of an ultrasonic impact treatment. In an example method, operational parameters of an ultrasonic impact treatment device are selected based upon the one or more physical characteristics of the downhole tool. The ultrasonic impact treatment device is configured to correspond to the selected operational parameters. A residual compressive stress layer is then induced along a surface of the downhole tool using the configured ultrasonic impact treatment device, thereby improving the useful life of the downhole tool.
