| 摘 要： | 根据摩擦与磨损原理，研究了两种齿形的ＰＤＣ钻头在不同钻井参数下钻进过程中进行简易取心时岩石的磨损状况，分析了切削齿的磨损速度与岩石的岩性、钻压以及转速的关系，并进一步确定了切削齿的磨损速度与磨损高度的关系。结果表明，钻头切削齿的磨损速度与钻压、转速成非线性关系，并且磨损速度受磨损高度的影响。根据试验结果，得出了钻头切削齿磨损速度的综合模式。

| Abstract: | Based on the principle of friction and wear, the wear effects of PDC bit with two profiles of cutters in different drilling conditions are studied experimentally.The relationships of the wear rate of the PDC cutter with rock types. weight on bit and rotary speed of bit are analyzed.In addition, the variation of wear rate of PDC cutter with worn height are investigated.The results of experiments show that the wear rate of PDC cutter is varied with the weight on bit. rotary speed and the worn height of cutter. A model equation for calculating the wear rate of the PDC cutter is presented. |
