摘要
优化井眼轨道设计是保证井身质量,减少井下事故,降低钻井成本的关键环节之一。三维多目标定向井井眼轨道的设计方法众多,但在设计中人为主观因素较多,通常,设计出来的井眼轨道较难成为最优化的轨道。COM-PASS(兰德马克轨道设计软件)定向井软件是将非线性数学理论引入到全井井眼轨道的最优化设计中,综合了各种设计方法的优点,简化了设计程序,对于三维多目标井的设计,只需设计者提供必要的约束条件即可设计出操作性强、经济、安全的最优井眼轨道。
Optimizing wellbore trajectory design is the key link to ensure the quality of well bore, decrease accidents in well hole and lower drilling cost. There are many methods to design the wellbore trajectory of three--dimensional multi--target directional well, but more subjective factors in design make it difficult be an optimized one. Compass directional well software（Landmark trajectory design software）has introduced the theory of non-linear math into optimizing design of the wellbore trajectory, which has synthesized the advantages of all kinds of design methods, simplified the design program, and all designer needs to do is to specify sofne necessary restrictions to design an operable,economic and safe optimized wellbore trajectory.
