螺杆钻具与PDC钻头组合钻井工艺技术是近年来国内外应用的一项钻井新技术。本文分析了PDC钻头特性,总结了螺杆钻具的使用注意事项,分析了螺杆钻具加PDC钻头组合和泥浆、扭矩之间的联系。螺杆钻具与PDC钻头组合钻井工艺技术的应用充分发挥了螺杆钻具和PDC钻头的各自优点,进一步提高了PDC钻头在井底的旋转速度,充分发挥了PDC钻头在高转速下钻速快的优势,大大提高了钻井速度,解决了许多钻井工程上的问题,降低了钻井成本,获得了丰厚的经济利润。
Screw Drilling and PDC Bit Combination Drilling technology is a new drilling technology applied at home and abroad in recent years. This paper analyzes the PDC bit characteristics, summarizes the use of screwdriver precautions, analysis of the screwdriver plus PDC bit combination and the relationship between mud and torque. The combination of screw drilling tool and PDC bit drilling technology makes full use of the advantages of screw drilling tool and PDC bit to further improve the rotation speed of PDC bit at the bottom of the hole and give full play to the PDC bit drilling speed at high speed Advantages, greatly improve the drilling speed, solve many problems on the drilling engineering, reducing drilling costs, access to a huge economic profit.
