摘    要：作者研制出一种双层胎体结构的孕镶金刚石钻头。该钻头特别适合钻进极坚硬地层,能够克服钻头打滑现象,其钻进效率与钻头寿命比一般金刚石钻头高几倍到十几倍。

Abstract: A new type of diamond-impregnated bits that possess the matrix of double-layer consti-tution recommended in this paper can overcome the appearance of bit slipping and can raisedrilling rate and service life many times compared with the general bits in drilling extra-hardformations.
