AN EXPERIMENTAL STUDY ON DRILLING TOOL DEFICIENCY TESTING USING METAL MAGNETIC MEMORY TECHNIQUE

摘要：

It is well known that the status of the drilling tools is a significant problem in the oil drilling industry. In present, many forms of non-destructive testing methods are used to test drilling tools in the oil industry, but there are still some considerable deficiencies in these methods. To solve this problem, a new non-destructive testing method—metal magnetic memory technology (MMMT) is presented in the paper. A new scientific type of test device and a test method are designed in the experimental research. The experiment is mainly to gain the characteristics of magnetic memory signals of the samples from drilling tools in static tension and pressing crack experiment. Through analyzing the experimental data, the primary relationship between stress value and magnetic memory signal is established.
