Abstract

The invention provides a double-well flexible roller oil pumping unit. The double-well flexible roller oil pumping unit comprises a large base; two guide wheel supporting plates are fixedly installed on the left side and the right side of the large base correspondingly; and flexible polish rod anti-disengaging pressing rods are arranged on one sides of the guide wheel supporting plates, and flexible polish rod guide wheels are arranged on the tops of the guide wheel supporting plates. According to the double-well flexible roller oil pumping unit, the functions of a motor and a speed reducer are integrated through a direct-drive roller, the production cost of the double-well flexible roller oil pumping unit is reduced, and the size of the double-well flexible roller oil pumping unit is reduced; one machine is adopted to drive double wells, the machine and the double wells are mutually balanced, the double-well flexible roller oil pumping unit is reasonable in assembly structure, compact in appearance, capable of being directly installed on a ground foundation, low in height, small in occupied area, flexible in movement, and convenient to install; and meanwhile, compared with a traditional oil pumping unit, the double-well flexible roller oil pumping unit is free of parts such as a support, a walking beam, a cross beam, a connecting rod, a speed reducer cylinder and a horse head, easy and convenient to manufacture and capable of achieving two wells, and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the petroleum field, in particular to a double-well flexible drum pumping unit. Background technique [0002] Pumping unit oil production is the most widely used main production method in the production process of oil wells. At present, although there are many types of pumping unit oil recovery technologies used on site, such as beam type, chain type, sky wheel type, etc., the structures are different, but their common All of them are based on the concept of one pumping unit for one oil well, that is, "one well and one pumping unit". [0003] In recent years, with the development of secondary well technology and the development of oilfields in the middle and late stages, the number of oil wells has increased significantly. Since each oil well needs to install and use a pumping unit, it requires a large amount of investment in infrastructure equipment, Energy consumption, management and maintenance costs and manpower increase t...
