高胎体金刚石钻头设计制造中的几个关键技术

Several Key Technologies in the Design and Manufacture of Diamond Drill Bit with High Matrix

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.
