By studying the application of sandwich-structured synthetic diamond core bits,following results are concluded: Matrix hardness can be HRC3-5 higher than that of similar ordinary ones;Finer diamond can be used partly as substitute of coarse ones,or even a fraction smaller size can be adopted,which can reduce the cost with better performance especially for drilling medium to hard formation(grade 8-10);Many factors should be considered when designing the width of interlayer,and usually it should be 1/5 to 1/4 that of the kerfs.The problem of short working life of core bit because of wearing out of the inner wear-resistant layer can be solved by adding 5% to 8% RVD_2 of 70/80 mesh to strengthen the inner layer or the width of inner layer being 1/3 that of the kerfs.Such experience is beneficial to the manufacturing technology of Sandwich-structured Diamond Core Bits.

通过对夹层结构金刚石钻头的应用研究发现,与同类普通金刚石钻头相比,该钻头的胎体配方硬度可以高HRC3~5;可以适当采用部分细粒度的金刚石替代粗粒度,甚至可以细一个粒度级,在降低成本的同时也能取得较好的效果,特别是在中硬地层(8~10级)钻进时效果尤其明显;易磨损层宽度的设计影响因素很多,总宽度一般是钻头的径向厚度的1/5~1/4比较好;在内缘耐磨层中添加5%~8%的RVD2型70/80目的金刚石进行弥散强化,或者将内缘耐磨层宽度设计成钻头宽度的1/3左右,可解决内缘耐磨层过早磨损而使钻头提前失效的问题。这些经验完善了夹层结构金刚石钻头的制造技术。
