新型分层复合型金刚石钻头的研制

Development of a New Type of Layered Composite Diamond Bit

摘要:

采用常规热压法制备出了一种分层复合型结构的金刚石钻头，该钻头对岩层的适应性大，具有一定的广谱性。经与普通型钻头对比试验发现，分层复合型结构钻头钻进速度大大提高，同时钻头使用寿命也有了一定的提高。

Abstract:

A kind of layered composite diamond bit is prepared by conventional hot pressing, the adaptability of this bit to rock layer is greatly improved with a certain universal property. Comparison tests are carried out with common bits, the drilling speed of the layered composite-structure diamond bit is greatly increased with prolonged service life.
