摘    要:金矿复杂地层金刚石钻进存在岩石坚硬、地层打滑、漏失等问题,影响钻头寿命和钻进效率。在山东招远某金矿勘探中,通过对3个单位制造的金刚石钻头进行现场对比试验研究,证明JBD-75S仿生金刚石钻头在提高钻头寿命方面具有较大的优越性,适合该复杂地层钻进。

关 键 词:金矿钻探  复杂地层  金刚石钻头  仿生钻头  试验研究

Abstract:Service life and drilling efficiency of diamond bit were affected by hard rock,slipping formation and fluid leakage in gold mine of complex stratum.It was proved that JBD-75S bionic diamond bit has more advantages for drilling in complex stratum than other types of bit by field optimizing experimental research in Zhaoyuan gold mine of Shangdong Province.
Keywords:drilling in gold mine  complex stratum  diamond bit  bionic bit  experimental research
