| Abstract: | To improve the reliability of the PDC cutting teeth selection, from the perspective of thermal performance, the PDC cutting teeth of different manufacturers were analyzed by the laser Raman spectroscopy at room temperature and high temperature and the thermogravimetry analysis. Combined with high temperature wear ratio test, the residual stress, the graphitization transformation, the thermal stability and the high temperature wear resistance of the PDC cutting teeth were analyzed to comprehensively evaluate the performance of the PDC cutting teeth of different manufacturers. At the same time, four-wing arc angle PDC bits with diameter of 94 mm was made and the field drilling test were carried out. The results show that the field test results are basically consistent with the results of the PDC cutting teeth thermal performance testing and analysis. The PDC cutting teeth with excellent thermal performance have high wear ratio at high temperature and excellent drilling performance, with an average aging of 25.0 m/h and an average life of 266 m. Compared with other PDC cutting teeth whose thermal properties are slightly worse, their performances are improved in varying degrees. Therefore, it is helpful to improve the accuracy of the PDC cutting tooth selection by improving and supplementing the macro detection method of PDC from the micro point of view. |
