摘要
为解决深水钻井面临的复杂井控问题,根据海底泥浆举升钻井系统的基本结构及工作原理,建立一个由变频器、电机、举升泵、泥浆循环管路组成的控制对象模型,结合控制对象为大惯性、非线性系统的特点,采用一种基于自适应模糊PID调节器的压力、转速双闭环控制策略,利用Matlab/Simulink软件构建系统仿真模型,分析结果表明,基于自适应模糊PID控制的压力、转速双闭环控制策略能够在海底泥浆举升钻井系统中取得很好的控制效果,使系统及时应对多种随机干扰。研究结果可为海底泥浆举升钻井控制提供参考。
To solve the complicated well control problems encountered in deepwater drilling, based on the analysis of the basic structure, working principle and operation condition of the subsea mud lift drilling system, we built a control object model composed of frequency converter, motor, lift pump and mud circulation pipeline. Considering that the control object is a large inertia and nonlinear system, a dual closed loop control strategy of pressure and speed based on adaptive fuzzy PID regulator was adopted. With the help of Fuzzy toolbox provided by Matlab/Simulink, a simulation model of subsea mud lift drilling system was built. The results show that the dual closed loop control strategy of pressure and speed based on adaptive fuzzy PID regulator can achieve better control effect, and enable the system to deal with multiple random disturbances in time. The results can provide some reference for control of subsea mud lift drilling.
