Abstract

The invention belongs to the field of oil drilling and production, and relates to an intelligent stroke frequency control device and method of an electric submersible pump oil pumping system. The device comprises a pressure and temperature sensor, an intelligent stroke frequency controller and a frequency converter which are sequentially connected, wherein the pressure and temperature sensor is located at a suction inlet of an electric submersible pump and used for collecting downhole pressure and temperature information; the frequency converter is connected with a pumping unit and used for adjusting the frequency of a motor of the pumping unit; and the intelligent stroke frequency controller comprises a pressure and temperature information collection unit, a man-machine operating interface, an actual working fluid level calculating unit, a stroke frequency adjusting unit and a frequency converter output control unit. The overall local control scheme of data collection, processing and control is provided, pumping unit control assistance by a remote computer is not needed, empty pumping of the pumping unit is effectively avoided, and the oil recovery efficiency of an oil field is improved.

Description

Technical field [0001] The invention belongs to the field of oil drilling and production, and relates to an intelligent stroke control device and a control method of an electric submersible pump oil pumping system. Background technique [0002] The electric submersible plunger pump pumping system is one of the artificial lift pumping systems. During the reciprocating pumping process of the pumping unit, if the pump body is exposed to the oil (that is, the pumping unit is empty), Working for a long time will result in increased equipment wear and waste, and even damage to the pumping equipment. [0003] When the mechanical structure of the pumping unit has been determined, the factors affecting the oil recovery efficiency of the system include the oil supply capacity and stroke frequency. In general, the higher the stroke, the lower the oil level. Therefore, in order to avoid the occurrence of the phenomenon of empty pumping of the pumping unit and to ensure the oil recovery effic...
