中曲率水平井入靶设计与控制技术

Design and control of target-entering in drilling medium-curvature horizontal well

入靶精度体现了造斜段的轨迹控制水平,也是水平段钻遇油层的前期保证。通过总结辽河油田近几年完成的数十口水平井的设计与施工情况,对水平井入靶设计和施工中着陆点的控制提出了若干原则和方法,对于不同类型水平井的入靶设计与施工具有指导意义。

The accuracy of target-entering is an indication of trajectory control in build-up section and is a guarantee of drilling into oil reservoir.This paper summarizes tens of horizontal wells drilled in recent years in Liaohe Oilfield,proposes some principles and methods of target-entering design and reservoirlanding point control,and is of significance to drilling of different horizontal wells.
