| 摘 要： | 针对常规PDC钻头在胜利油田临盘地区定向井钻进过程中存在的工具面不稳定、井斜角和方位角难以控制、滑动钻进时钻速较低等问题，研究分析了PDC钻头的剖面形状、切削结构、保径设计等对钻头导向性能的影响规律，在此基础上，研制出一种适合临盘地区地层特性的BTM115H型导向PDC钻头。该型PDC钻头采用浅内锥、双圆弧剖面形状，特殊双重切削布齿、短保径设计和侧向力平衡设计，能够有效提高钻头的导向性能和机械钻速。多口定向井的现场应用效果表明，BTM115H型导向PDC钻头在定向钻进过程中，工具面可控性好，复合钻井速度和定向机械钻速较常规PDC钻头都有大幅度提高，为临盘地区的定向井快速钻进提供了有力保障。

| Abstract: | In order to resolve the problems caused by conventional PDC bit in drilling directional wells in Linpan Area of Shengli Oilfield,such as the instable tool face,difficulty to control inclination and azimuth,low drilling speed etc,a new steerable PDC bit was developed based on the analysis of bit profile,cutting structure,gauge design for steerable capability.The new steerable PDC bit was designed with shallow inner cone,double circular section,double cutter structure and short gauge design,and its stability ... |
