三维定向钻孔轨迹设计与施工控制新方法

New Designing and Construction Method for Contrlling Hole Trajetory in three Demensional Direacted Drilling

阐述了设计三维定向钻孔轨迹的新方法。该方法利用了倾斜平面倾斜角这一概念把空间三维设计转化为平面上的二维设计。据此建立了计算孔身轨迹的数学模式，提出了控制孔身轨迹的措施，并且与其他两种设计方法进行了对比。

Making use of the inclined angle of an inclined plane is able to convert a spatial three dimensional designing into a two dimen-sional one on a plane,On the basis.of this conception a mathematical model for calculating the drill hole trajectory is established.Measures for controlling the hole trajectory are put forward.A comparative analysis of our designing method with other methodshas also been made.
