摘　　要：为研究金刚石钻头胎体性能及金刚石粒度对微烧出刃技术出刃时间的影响,采用自行研制的微型岩心试验台开展了微型岩心钻进试验。选用28/20微型取心钻头,先在铁块上磨钝,然后在花岗岩上进行微烧出刃试验。结果表明,钻头微烧出刃时间随着胎体耐磨性的降低而递减;高熔点高红硬性胎体的微烧出刃时间更长;金刚石粒度在0.2~0.5 mm范围内,对微烧出刃时间影响不大。微烧出刃技术适用于小功率设备,但存在一定烧钻风险,需要丰富的施工经验和严格控制,以防止烧钻事故发生。选择合适的胎体和金刚石,严格控制技术参数,可以达到理想的出刃效果和较长的使用寿命。In order to study the influence of the performance of diamond drill bit matrixs and the diamond particle size on the emergence time of micro-burning edge technology,a micro-core drilling experiment was carried out using a self-made micro-core test bench.28/20 micro-coring bits were selected,first blunted on an iron block,and then micro-burning blade experiments were carried out on granite.The results show that the micro-burning blade time has decreased as the matrix wear resistance decreases.High melting point and high red hardness matrix have longer micro-burning blade time.The diamond particle size in the range of 0.2-0.5 mm has little effect on the micro-burning blade time.Microburning blade technology is suitable for low-power equipment,but there are some risks of burning drilling,requiring abundant construction experience and strict control to prevent burning drilling accidents.Choosing a suitable matrix and diamond,and strictly controlling technical parameters can achieve the ideal tipping effect and longer service life.
