在介绍滑动导向钻具组合复合钻井导向力计算方法的基础上 ,主要探讨了复合钻井方式下 ,滑动式导向钻具组合的导向能力预测方法。结果表明 ,滑动式导向钻具组合复合钻井时的导向能力可以用平衡侧向力法进行预测 Based on the introduction of the calculation method of the sliding guide-hole assembly composite drilling guidance force, this paper mainly discusses the prediction of the guidance ability of the sliding-type guide-hole drilling assembly under the complex drilling method. The results show that the guidance ability of the sliding-type composite drill can be predicted by the balanced lateral force method
