摘要
本文介绍了使用54型弯外壳在钻探施工定向孔纠斜的效果,结合实践经验用此还可纠顶角和方位角.
This paper expounds the results achieved by using the φ-54mm bent outer casing type whipstock to rectify the deviation of a directional hole. Inclination and direction of bore holes are corrected in the light of experience drawn from productive practice.
