| 摘 要： | 本文首先介绍一种用于卵砾石地层钻进的新型针状硬质合金钻头的设计原理，而后简要说明其胎体配方组成机理。在分析胎体性能要求的基础上，选择了六组配方，对其进行抗弯强度、抗剪强度，硬度性能、冲击韧性、SEM照片等试验，优选了四号配方，试制了钻头。生产试验结果表明，这种新型复合型钻头钻进萝日砾石地层的平均时效1．89m／h、平均每回次进尺为2．3m，平均钻头寿命19．81m，具有实用和推广价值。 |

| Abstract: | Abatract The paper firstly introduces the designing principle of a new-type alloy-diamond bit for the gravel stratum, secondlyexplains briefly the mechanism of matrix composition for the new-type bit.Six groups of matrix compositions were tested forbending strength,shearing strength,hardness,impact toughness as well as the SEM pictures.The group No.4 was finally selectedto make the bits for field application test.The result of the field test indicated that, the new-type bit had average hour-efficiencyof 1.89m/h,2.3m of average drilling depth and 19.81m of average life-span in drilling the gravel stratum and has practical valueto popularize. |
