Closed-Loop Feedback Simulation to Process of Ram Blowout Preventer Shut-in Locking

近年井控培训多以教师讲解为主,虚拟仿真使学员难以理解实际操作。钻井井控实物仿真培训系统的应用,可有效解决井控培训中场景不易复现、培训成本高等问题。针对井控实物仿真培训系统中关井时闸板防喷器锁紧操作的仿真化,在闸板防喷器中加装步进电机驱动器和步进电机,利用步进电机速度及转矩控制实现闸板防喷器锁紧装置的锁紧操作,提出基于闸板防喷器锁紧过程步进电机的闭环回馈控制系统。为验证方法可行性,利用井控设备进行仿真计算,实验结果证明其可靠性及实用性。

Well control training was explained mainly by teacher in recent years. Virtual simulation made it difficult for students to understand the actual operation. Application of drilling well control simulation training system solved effectively the problem of the scene seldom repetition and high cost of well control training. For the simulation of the process of ram blowout preventer shut-in locking in the well controlled physical simulation training system, the stepping motor driver and the stepping motor were installed in ram blowout preventer, and locking operation of the lock device was realized by using speed and torque of the stepping motor for the ram blowout preventer. The closed-loop feedback control system of the stepping motor based on the lock of the ram blowout preventer was proposed. To verify the feasibility of the method, the well control equipment was taken as the background of simulation calculation. Experimental results show the technique reliability and practicability.
