水平定向对接穿越及导向技术研究

Study of Horizontal Directional Intersection and Guidance Technology

摘要:

水平定向对接穿越技术有效解决了传统水平定向钻进无法完成长距离穿越，以及无法穿越两侧均含砾石等复杂地层的问题。介绍了水平定向对接穿越技术以及该技术在国内外的应用，详细分析了基于三轴加速度计和三轴磁阻传感器的对接穿越导向技术，基于轴向磁铁产生的磁场建立了对接模型。

Abstract:

The horizontal directional intersection (HDI) technology effectively solves the problems that the long-distance crossing and the gravel stratum crossing can't be realized by the traditional horizontal directional drilling (HDD). This paper introduced the horizontal directional intersection technology and its application both at home and abroad, analyzed the crossing intersection guidance technology that was based on triaxial accelerometers and triaxial reluctance sensor in great detail; and intersection model was established based on the magnetic field generated from an axial magnet.
