摘要
采用不同于常规金刚石钻头的设计理念,选用高强度金刚石及耐磨金刚石聚晶体,对普通金刚石钻头胎体配方进行了改进,对常规金刚石钻头的烧结工艺参数作了适当的调整,试制出大直径加强型金刚石钻头。该钻头在耐磨性、抗冲击韧性及保径等方面较常规金刚石钻头显现出较大优势。在不改变常规钻进参数的情况下,较好地解决了卵砾石、破碎地层钻头寿命短、钻进速度慢、钻头易过早损坏等问题,可供类似的地层钻探施工选用。
With different design idea,improvement was made on matrix formula of traditional diamond bit by selecting high strength diamond and wear-resistance diamond polycrystalline and adjustment was made on the sintering parameters of traditional diamond bit.A large diameter reinforced diamond bit was developed,which has advantages over traditional diamond bit in wearing-resistance,anti-impact toughness and bit diameter retention.The bit service life in gravel and broken formations and drilling rate were improved with no changes of traditional drilling parameters.
