摘    要:TorkBuster扭力冲击器是一种纯机械动力工具,应用表明,TorkBuster扭力冲击器配合PDC钻头一起使用提高机械钻速效果显著。新疆油田引进扭力冲击器配合PDC钻头在环玛湖探区使用,现场应用发现该工具在部分井区应用尚未达到预期提速效果,机械钻速较低。分析TorkBuster扭力冲击器在环玛湖探区实际应用情况发现TorkBuster扭力冲击器+PDC钻头钻速受钻头泥包问题、钻头崩齿问题、钻井液体系问题等因素影响较大。通过有针对性的改进钻井措施,有效地提高了TorkBuster扭力冲击器+PDC钻头钻速。现场应用的9口井中,平均机械钻速提高到7.05 m/h,较改进措施前提高156.65%,平均每口井钻井周期节约9.68 d,达到了预期提速的要求。

关 键 词:TorkBuster扭力冲击器  钻速影响因素  钻头泥包  钻头崩齿  钻井液体系

Abstract:TorkBuster was a purely machanical power tool.Practice in other oilfields indicated that TorkBuster drilling tool could obviously improve ROP when it was used with PDC bit.Xinjiang oilfield brought in TorkBuster drilling tool which was used in circum-mahu lake with PDC bit and field application showed that TorkBuster drilling tool failed to get the expected result in part of wells with low ROP.After analyzing practical application situation of TorkBuster drilling tool,ROP was deeply influenced by bit balling,falling out of teeth and drilling fluid system.Through these customized and improved technical measuses,the drilling speed of TorkBuster drilling tool matched with PDC bit was increased greatly.In 9 wells to which these techniques have been applied,the average rate of penetration was 7.05 m/h,up by 156.65%.Drilling period of each well was shortend by 9.68 d and expected aim was reached.
Keywords:TorkBuster torsional rimpactor  influence factor of ROP  bit balling  falling out of teeth  drilling fluid system
