摘　　要：根据油气钻井送钻要求,以电气的控制和执行机构构建电气自动送钻控制系统,给出了系统控制框图;简单介绍了恒钻速、恒钻压以及最近在国外比较流行的恒压差3种送钻方式及控制要求,叙述了组成电气控制系统的关键要素、控制方法及其优缺点,特别指出了在实际运行中,为了降低装置发热和能量损耗,需要进行的控制结构变换。According to the requirements of oil and gas feed drilling control, taking electric control and actuator to build the electric automatic drilling control system, the system control diagrams are put forward. Three feed drilling ways and control requirements of constant drilling speed, constant WOB and constant presure difference which is popular in foreign countries recently are introduced briefly. The key elements, control methods and its advantages and disadvantages of control system are described, and the control structural transformation in order to reduce the heating and energy loss of device and motor in the actual operation is particularly pointed out.
