深孔绳索取心金刚石钻头性能参数探讨

Discussion of Performance Parameters for Wire-line Diamond Coring Bit in Deep Hole

摘要:

深孔绳索取心钻进对金刚石钻头的性能提出了更高的要求。从分析金刚石钻头的性能对钻进的影响入手，着重对满足深孔绳索取心钻进要求的金刚石钻头制造方法与性能参数进行了探讨，在综合国内外先进经验的基础上总结提出了新型钻头的参数指标。

Abstract:

Wire-line coring drilling put forward higher requirements to the parameters of diamond bit. By the analysis on the influence of diamond bit performance to drilling operation, discussion was made on the manufacture and performance parameters of diamond bit to satisfy wire-line coring drilling in deep hole. The parameter indexes of new type of bit are suggested based on the advanced experiences both in China and abroad.
