| 摘 要： | 井眼轨道设计是多分支井钻进中的关键环节,它直接影响到后序工作能否顺利进行.以造斜工具能否实现为目标,在分支井眼和主井眼的不同的直线夹角下,研究分支处造斜率随着终点与侧钻点的距离不同产生的变化规律,来优选出分支处的弯曲段长度和直线夹角等经验参数,对分支井井眼轨道参数的优化具有一定的指导意义.

| Abstract: | Well trajectory design of multilateral well is a key link in well drilling,which determines the result of the following operation.The paper analyzes the variation trend of build-up rate caused by the different shortest straight line distance under certain angle between multilateral well main borehole and branch borehole.Based on the build-up rate of building motor assemblies,the paper presents empirical parameters about the length of curved section and the value of the angle,which have the guidance for optimizing the design parameters of multilateral well trajectory. |

| Keywords: | multilateral well well trajectory angle between two straight lines optimizing |
