| 摘 要： | 采用热压烧结方法制备5种不同胎体硬度和唇面形状的金刚石钻头，试验于工程勘探中，与常用的电镀金刚石钻头比较，分析其钻进时效情况。结果表明：通过优化设计，热压烧结钻头同样适用于工程勘探领域，其钻进时效与现行电镀钻头的钻进时效相当，甚至更高；对于微风化灰岩地层，热压烧结钻头的胎体硬度越低，其钻进时效越高，胎体硬度越高，其钻进时效越低；异形齿设计比平齿设计的热压烧结钻头的唇面更易出刃，其钻进时效较高。

| Abstract: | 5 kinds of diamond drilling bits were prepared with different matrix hardness and profiles by hot pressing sinte-ring method, which were tested in engineering exploration and compared with the common electroplated diamond drilling bits to analyze the drilling efficiency.The result shows that by optimized design, the hot pressing sintering diamond bits are suitable for engineering exploration equally, their drilling efficiency are almost equal to or even higher than that of the elec-troplated diamond drilling bits.In weathered limestone formation drilling, the lower the matrix hardness of hot pressing sin-tering bit, the higher the drilling efficiency, and vice versa.The profile of bit by special teeth design is faster exposed than that by plain teeth design with higher drilling efficiency. |
