摘　　要：方位漂移是影响定向井准确中靶的主要因素之一。根据定向井施工中“井斜角较大时 ,方位漂移量相对较小”的规律 ,提出了“通过缩短较小井斜角斜井段长来减少施工过程中的方位漂移量”的方法 ,并介绍了实现该方法的 2种途径。In the drilling of the directional well,azimuth drift is a key factor of effecting the drilling rate.When the deviation angle is more higher,azimuth drift is smaller.According to the rule,if the length of deviated section is shortened, in which the deviation angle is smaller,azimuth drift in the directional well is decreased.The paper introduces two ways to accomplish the method.
