Abstract

The present invention discloses one kind of linear motor driven pumping unit, which includes linear motor, frame, composite guide wheel, two steel cables, polished rod eye, balancing guide wheel, counter weight, and pedestal. The composite guide wheel and the balancing guide wheel set on the top cross beam of the frame have horizontal rotation shafts, the first steel cable has its first end connected to the second steel cable and fixed to the polished rod eye and the other end fixed to the mover of the linear motor through the composite guide wheel, the second steel cable has its second end fixed to the counter weight through the balancing guide wheel, the frame has its lower end fixed on the pedestal, and the linear motor has stator fixed on the upright of the frame vertically; and the polished rod eye is fixed to the upper end of the sucker rod. The mover of the linear motor reciprocates up and down to complete the oil pumping. The present invention has low power consumption, and changeable stroke and inertial load.

Description

Technical field: [0001] The invention relates to an oil pump driven by a linear motor. Background technique: [0002] At present, the energy consumption of pumping units occupies a considerable proportion in the cost of oil production. Therefore, the energy saving and consumption reduction of the pumping unit oil production system is the focus of energy saving in the oil production process. The composition of the most widely used conventional beam pumping unit oil production system is shown in Figure 1. The oil production system is mainly composed of three parts: the ground part-beam pumping unit, which consists of a motor 11, a reduction box 12 and four Connecting rod mechanism 13 (comprising crank, connecting rod, crossbeam, traveling beam), donkey head and rope hanger etc. are made up; Underground part-oil well pump 17 is suspended in the lower end of oil pipe 15 in casing pipe 16; Connect ground and underground part The middle part, the sucker rod 14, consists of one o...
