定向井侧钻技术

Side Tracking Technique in Directional Well

摘要:

结合我国首例定向井双重套管开窗例钻修井实例，详述了定向井侧钻工艺及其应用效果，介绍了提高定向井侧钻效率、降低成本的方法，指出定向井开窗成败主要取决于导斜器的安装方位。

Abstract:

With referemce to the first case of cutting a window in the dual case set in a directinal well for side traking process and its effect in directional wells. Methods of incteasing side tracking efficiency and reducing cost are presented It is concluded that whether side tracking in derectional wels succed or not mainly depends on the orientatio of the deflection wedge.
