在钻探生产中经常遇到砂卵石层 ,砂卵石层中石英含量高 ,坚硬 ,研磨性强 ,形状各异 ,大小不一 ,钢粒钻进和硬质合金钻进都不适用钻进砂卵石层 ;普通金刚石钻头钻进中窜动厉害 ,对钻头胎体冲击大 ,钻头磨损特别快 ,寿命低 ,而且容易掉块 ,给钻进带来麻烦 ,使钻进成本上升。针对砂卵石地层特点 ,提出研制适用于砂卵石层金刚石钻头的设计与制造思路
Commonly encountered in the drilling production of sand and gravel layer, sand and pebble layer of quartz content, hard, abrasive, different shapes, sizes, steel drilling and cemented carbide are not suitable for drilling sand and gravel Layer; common diamond drill drilling in the powerful, big impact on the drill bit matrix, drill wear particularly fast, low life expectancy, and easy to block, bring trouble to drilling, drilling costs rise. According to the characteristics of sand and gravel stratum, it is proposed to develop the design and manufacture ideas applicable to sand and gravel diamond drill
