定向钻孔设计是解决孔斜问题，特别是在地质条件复杂、钻孔较深等情况下，保证钻到预定的位置，满足地质要求的一种方法。58年竹山队斜孔钻进钻孔上漂现象严重（如CK_1孔终孔位置与设计要求就相差60米），经采用了定向钻进后，就基本上能钻到预定地点，满足地质要求。现将其进行定向钻孔设计的步骤和方法介绍如下：一、研究钻孔的弯曲规律性竹山队钻进的岩石是5—6级炭质绢云母片岩，
Directional drilling design is to solve the problem of hole inclination, especially in the case of complex geological conditions, deep drilling and other circumstances, to ensure drilling to a predetermined location, to meet the geological requirements of a method. 58 years Zhushan oblique hole drilling drilling drift phenomenon (such as CK_1 hole end hole location and design requirements of a difference of 60 meters), the use of directional drilling, it can basically drill to a predetermined location to meet the geological requirements . Now its directional drilling design steps and methods are described below: First, the study of drilling regularity of bending The bamboo is drilled into the rock is 5-6 carbonaceous sericite schist,
