Application of Simple Eccentric Wedge in Drilling Construction

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.
