It aimed to dynamic change of oilfield productivity, maked sure that the progressing cavity pump is working in a highly efficient region. It combined variable frequency conversion technology and dynamic liquid level height control technology, the closed-loop control of oil production system with progressing cavity pump is made up of rotation-speed and torsion sensor, stepless motor, frequency converter, PLC and progressing cavity pump. The result show that the system can control the pump submergence depth by adjusting the rotation-speed and torsion of polish rod, and make sure the pump working in a highly efficient region finally. This system also can increase recovery efficiency and pump service life.
