孕镶金刚石钻头破碎花岗岩岩屑粒径分布研究
|
摘要
收集微钻实验过程中孕镶金刚石钻头破碎花岗岩所产生的岩屑,分析其粒径分布,定量研究金刚石参数、钻进参数对岩屑粒径分布的影响。结果表明:岩屑粒径在一定范围内呈单峰值分布,粒径尺寸集中分布在40～100μm,粒径分布基本符合对数正态分布规律;金刚石粒度、浓度,钻压和转速对岩屑的粒径分布有较大的影响。
The granite swarf produced by impregnated diamond bits were collected during micro-drilling experiments. The particle size distributions of the swarf were analyzed to quantitatively investigate the particle size distribution laws and the effects of diamond parameters and drilling parameters on the swarf size distributions. The results show that the particle size distribution of the granite swarf is consistent with logarithmic normal distribution. Most swarf particle sizes vary from 40 to 100 μm. Meanwhile, the swarf particle size distribution is influenced by the diamond size, diamond concentration, bit pressure and rotate speed.
