The composite drum type pulsatively reducing energy saving pumping unit includes a pulsative reducer connected to a motor, a work barrel and a balancing barrel connected to the output shaft of the pulsative reducer, an support arm corresponding to the work barrel, a pulley connected to the front end of the support arm, a flexible driving part wound on the work barrel and connected to oil extracting pump in well, and an steel cable wound on the balancing barrel and connected to the balancing box. The present invention is superior to available walking beam pumping unit, and has the features of high effective load factor, low power consumption, small size, less dead weight and low cost.
Description
Technical field: [0001] The invention relates to a lifting device used in the field of oil field mechanical oil recovery, in particular to a composite drum type pulsating deceleration energy-saving pumping unit. Background technique: [0002] Under the condition of market economy, the development of oil fields must focus on economic benefits, vigorously develop energy-saving pumping units, reduce energy consumption, and reduce oil production costs. In the cost of oil production, the electricity cost of the pumping unit accounts for about 30%. If the pumping unit system efficiency and power saving rate increase by 1%, it will bring considerable economic benefits. Therefore, it is of great significance to develop high-efficiency and energy-saving pumping units. With the development of oilfields and the continuous development of technology, there are various types of mechanical oil production equipment ranging from beam pumping units to electric submersible pumps and screw pump...
