摘　　要：侧钻作为一种钻井方法,在钻井过程中经常使用,但往往因为钻具组合不科学、不合理,钻时控制不到位,不注意侧钻细节,使侧钻变得复杂艰难,甚至反复几次侧钻都不成功。针对以上问题进行深入分析及探讨,通过科学合理的钻具组合及对钻时的精准控制、细节的准确把握,使侧钻循序渐进,提高侧钻效率。As a drilling method, sidetracking was often used in the drilling process. However, sidetracking became complex and difficult, even several sidetracking were not successful, because the drilling tool combination was unscientific and unreasonable, drilling control was not in place, and the sidetracking details were not paid attention to. The above problems were analyzed and discussed in depth. Through scientific and reasonable drilling tool combination, accurate control of drilling process and accurate grasp of the details, the sidetracking was gradually improved and the sidetracking efficiency was improved.
