摘要:
针对PDC钻头在硬质地层出现的黏滑振动问题,为改善PDC钻头受力状态,提高硬质地层的机械钻速,研制了旋冲振荡钻井提速工具。该工具以高压钻井液为驱动介质,能同时产生轴向冲击和扭转冲击。文中对工具的结构与原理进行了阐述,分析了工具内部腔体钻井液压力分布,计算得到了工具的冲击频率、冲击功等性能参数。室内实验结果表明:旋冲振荡钻井提速工具能实现轴向和扭转相耦合的冲击载荷,工具冲击频率和压降随着排量的增大而增大。现场试验结果表明:该工具能够实现提速减振效果,应用井段平均机械钻速提高了59.46%~84.33%,PDC钻头未出现崩齿现象。
Abstract:
In order to reduce the stick-slip effect of PDC bit when it is used in hard formation, improve the stress state of PDC bit and the rate of penetration, a rotary-percussive and oscillatory drilling tool is developed. The tool is driven by the high-pressure drilling fluid, which can generate both axial and torsional percussion. In this paper, the structure and principle of the rotary-percussive and oscillatory drilling tool were descripted. The pressure distribution of drilling fluid in the internal cavity of the tool was analyzed, and the performance parameters such as impact frequency and impact energy of the tool were calculated. The results of laboratory tests show that the rotary-percussive and oscillatory drilling tool can realize the axial and torsional coupling impact load, which verifies the feasibility of the tool, and its frequency and pressure drop increase with the increase of the rate of flow. The field application results show that the tool can achieve speed-up and vibration-damping effects, and the average rate of penetration of the applied well sections has increased by 59.46%-84.33%, and the PDC bit does not appear tooth breaking phenomenon.
