摘　　要：现有的井眼轨迹设计方法有很多种，涉及到二维的方法和三维方法。但它们有一个共同的缺点，就是设计出来的井眼轨迹不能从定量的角度确信为一条可行的最优轨迹。为此，文章把非线性不等式约束下非线性目标函数的非线性数学规划理论引入到定向井井眼轨迹的最优化设计中，提出了定向井井眼轨迹设计定量意义上的最优化方法。为讨论方便，文中以常用的双增型剖面为例，讨论其最优化的设计方法，并进行了方位漂移设计。应用此文的研究思路，稍加修改就可以得到Ｓ型等井眼剖面的最优化设计方法。这些理论和模型已经利用ＶｉｓｕａｌＢａｓｉｃ 语言编制成为一个用户界面非常友好的软件ＧＪＹＨＳＪ，操作简单，使用方便。The existing methods for designing well trajectory are varied,in which the 2 D and 3 D methods are involved.However,they have a common shortcoming that the designed well trajectory can not be sure to be a feasible optimized one quantitatively.For this reason,in this paper,the monlinear mathematical programming theory of the nonlinear objective function restrained by nonlinear inequality is introduced in the optimized design of directional well trajectory,putting forward a quantitative optimized method for designing directional well trajectory.For the convenience of study,the optimized design method is discussed and the azimuthal displacement design is made by taking the double build section most in use for example in this paper.An optimized design method for S type borehole section can be obtained by applying the train of thought in this paper and slightly modifying it.These theories and models have been programmed into the software GJYHSJ in Visual Basic,which has a very good user interface and is easy to be used.
