| 摘 要： | 随着地质岩心钻探孔深的不断增加，处理孔内事故的难度也越来越大。为了缩短施工周期，特复杂的孔内事故经常放弃处理。利用造价低廉、使用简单的偏心楔进行定向钻进，绕过事故孔段，是一种行之有效的处理手段。本文主要介绍了简易偏心楔的制作及在不同孔段中的应用。

| Abstract: | With the continuous increase of the geological core drilling hole depth, the hole accidents handling is more and more difficult. In order to shorten the construction period, particularly complex hole accidents are often given up, while a low-cost simple eccentric wedge is effectively used for directional drilling to bypass the accident section. This paper mainly introduces the simple eccentric wedge about its manufacture and the application in different drilling holes. |
