【摘要】 针对钻机工作过程中钻压的时变和非线性的基本特性,提出一种基于模糊控制技术的钻机自动送钻技术。根据模糊控制理论和钻井现场司钻的操作经验,建立相应的模糊控制规则,同时结合送钻电机矢量控制技术,设计了恒钻压送钻系统模糊控制器。仿真实验表明控制效果良好,系统的响应速度提高,对实际的设计与应用具有一定的指导意义。更多还原

【Abstract】 According to the basic characteristics such as nonlinear and time-varying of the drilling pressure in the drilling process,a kind of electronic rig WOB automatic drilling technology is presented based on fuzzy control.The relative fuzzy control rules is established on the basis of fuzzy control theory and on-site driller’s experiences.As well as the constant WOB automatic drilling system fuzzy controller is designed using vector control technology of bit-feed asynchronous motor.The simulation results show the well control effectness,and reponse speed of the system is also increased which give some guidance to the actual design and application.更多还原
