金刚石定位排布钻头设计

Design of Drill Bits with Diamond Positioning Arrangement

摘要:

对孕镶金刚石钻头中的金刚石定位排布方式和参数进行了分析，设计、制造出40/45目和50/60目金刚石定位排布钻头。在广西横县孟村矿区的钻进试验中，40/45目金刚石钻头的寿命是普通钻头的1.84倍；50/60目金刚石钻头的寿命是普通钻头的2.74倍，时效提高19.7%。

Abstract:

Analysis was made on the diamond positioning arrangement mode and parameters of impregnated diamond bit, 40/45 mesh and 50/60 mesh diamond positioning arrangement drill bits were designed and produced. In the drilling experiments of Mengcun mining area in Guangxi, the service life of 40/45 mesh diamond bit is respectively 1.84 times of conventional bit; the service life of 50/60 mesh diamond bit is respectively 2.74 times of conventional bit, and the drilling rate increased by 19.7%.
