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

Zhijie Ren

Abstract

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.
