乌克兰新型聚晶АКТМ与金刚石复合式钻头钻进坚硬岩石的研究
Study on drilling stiff rocks with compound bit of diamond and new-type Ukraine polycrystalline АКТМ
【摘要】 分析了新型聚晶材料АКТМ的物理-力学性质,研制了针状АКТМ与金刚石复合式钻头。试验研究了АКТМ直径对钻头钻进性能的影响,确定了最优尺寸。室内外钻进试验表明,这种复合式钻头能够有效钻进Ⅹ~Ⅺ级的坚硬岩石。
【Abstract】 The paper analyses the physical-mechanical properties of new-type polycrystalline АКТМ,and develops a compound bit made from needle-shaped АКТМ and diamond.The influence of АКТМ diameter on drillability is studied and the optimal diameter is determined.Lab and field drilling tests show that the com-pound bit effectively drills grade АКТМ stiff rocks.
