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. |

1. A method to improve useful life of a downhole tool, the method comprising:
providing a downhole tool having one or more physical characteristics; selecting operational parameters of an ultrasonic impact treatment device based upon the one or more physical characteristics of the downhole tool; configuring the ultrasonic impact treatment device to correspond to the selected operational parameters; and to inducing a residual compressive stress layer along a surface of the downhole tool using the configured ultrasonic impact treatment device, thereby improving the useful life of the downhole tool. |
