| 摘 要： | 为满足深部钻探需求,市场上出现了多种高胎体金刚石钻头。在野外钻进中,与普通金刚石钻头相比,高胎体金刚石钻头的使用寿命虽有提高,但并没有取得预期的理想效果。通过分析国内外几种高胎体金刚石钻头的优缺点,找出了影响高胎体钻头寿命的关键技术,并对这几点关键技术作了进一步的分析与研究。

| Abstract: | A variety of high-matrix diamond drill bits present in the market to meet the requirements of deep-hole drilling. In the field drilling, although the service life of high-matrix diamond bit has been further improved compared with the conventional ones, it did not achieve the desired effects. By analyzing the advantages and disadvantages of high-matrix diamond bits both in China and abroad, the key technologies affecting bit service life haven been found and further discussion and research were made on them. |
