| Abstract: | The damage forms of oil tube and its magnetic memory testing method were studied, A stress concentration magnetic diagnostic apparatus was used to test oil tube thread and detect circumferential crack, and the testing data was analyzed. Results showed that magnetic memory testing was an effective method for oil tube flaw and stress concentration degree. The first ten tubes and the eightieth to ninetieth oil tubes located at the portal of oil well should be the main part for testing, and their important testing regions were presented also. |
