液压式扭转冲击钻井提速技术研究

Research on the Speeding Technology of Hydraulic Type Torsional Percussion Drilling

研究扭转冲击破岩机理并进行仿真分析,借鉴国内外已有类似工具功能与结构形式,设计扭转冲击工具的工作原理和详细结构,实现了液动锤往复的摆动来形成双向高频扭转冲击。通过工具性能参数测试,表明所设计的扭转冲击工具满足现场应用要求。

The rock breaking mechanism by torsional percussion was studied and the simulation analysis was carried out. Based on similar tool functions and structural types, working principle and detailed structure of the torsional impact tool were designed by reciprocating swing of the hammer to form bi-directional high frequency torsional impact. After tool performance parameters testing, it was shown that the designed torsional impact tool meets field application requirement.
