偏心楔钻进技术的改进与应用

Improvement on Eccentric Wedge Drilling Technology and the Application

摘要:

偏心楔是定向钻进技术的一种方法和手段，偏心楔钻进技术的关键工序是孔底架桥和在硬岩地层过楔面钻进技术。通过生产、科研相结合，对液压金属孔底塞和金刚石钻头进行了改进研究，经过几年的生产应用和3个钻孔应用效果对比，取得了较好的效果。

Abstract:

The wedge is a means and method for directional drilling technique, its main process is hole-bottom bridging and hard rock ground drilling technique by means of wedge. With the combination of construction and scientific research, improvement was made on the hydraulic type hole-bottom metal plug and diamond bit. Through the construction for years and compared the application effects of 3 boreholes, good results were obtained.
