摘　　要：单弯导向钻具组合在钻井过程中要承受一个周期性的弯扭载荷,因此,其传动轴、联接扣易发生疲劳破坏、而马达的寿命较低,这在一定程度上限制了该钻具组合的推广应用。在分析产生上述问题的基础上,采取轴体防断措施,并对马达进行了改进,大幅度提高了动力钻具的使用寿命及安全系数。It is easy for single bend tools to take place drive shaft and connecting thread failures due to periodic bend loads during drilling. The failures reduce motor life and limit its popularization to certain degree. Based on the analysis of failures, measures were taken to protect shaft body from break , prolong motor life and improve safety factors.
