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

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。

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.
