摘要
为了对小直径自动导向钻具的研制开发与应用,介绍了一种采用无刷直流电机电控纠偏的控制系统,通过MC33035控制器驱动无刷直流电机与钻井钻具的导向块相连,电机直接控制导向块的伸缩来纠正钻具的垂直位置,分析了纠偏控制的基本工作原理,实现了电控纠偏的故障诊断与重启,保证钻头垂直钻进,电控纠偏在小直径垂直钻进领域有着重要的应用研究价值。
In order to the development and application of the small diameter automatic steering down hole discussed a new method of electronic control corrective control system used by brushless DC motor. Trough controller drive the brushless DC motor connect to guide block of the drilling, and the motor control of the guide block scale to correct drill vertical position. A based working principle of the rectify control are analyzed, realized the fault diagnosis of electronically controlled rectifying and restart to guarantee the drill vertical drilling. Electronically controlled rectifying in small diameter vertical drilling field has important application value.
