| 摘 要： | PDC钻头在难钻地层钻进时有“憋跳钻”现象严重、钻头机械钻速低、单只钻头进尺低等问题。研制了一种衡转矩钻井工具,该工具采用弹簧+螺旋导向机构的机械传动方式,实时存储、释放钻井转矩能量; 通过对钻头的破岩能量实时优化,实现了钻井转矩波动的“消峰填谷”,平稳钻进。试验结果表明,衡转矩钻井工具设计合理、性能可靠,可满足直井和定向井工程需求,能够有效减少钻井转矩波动、提高钻头进尺及机械钻速。

| Abstract: | Serious bit bouncing and stick slip problems in drilling hard formation with PDC bit often results in low ROP and bit footage,which decreases ROP and drilling footage.The torque balancer tool can store and release torque energy by spring and helical pair,realize drilling with PDC bit smoothly.The field test results show that tool has a rational design structure,reliable working performance and easy operation,which can effectively decrease drilling torque fluctuation,increase drilling footage and ROP per bit in both vertical and directional drilling with PDC bit. |
