Problems solved by technology

[0002] At present, there are many oil production machines in various oil fields, one of which is a conventional beam pumping unit with double wells. Because the actual well spacing on site has certain differences, it is necessary to align the two oil wells on site; when the two oil wells are close, the crank The oil well workover range at the nearer end is limited, and the beam is too long when the two oil wells are far away, which requires a special structure for the pumping unit

Embodiment Construction

[0012] Now in conjunction with accompanying drawing and specific embodiment the present invention is further described as follows:

[0013] As can be seen from the accompanying drawings, the rotary base (1) of the present invention is achieved through the following technical proposals. There are four sets of rollers (2) on both sides of the double well pumping unit base (1). When the rotary pumping unit First fix the center of rotation, loosen the fixing bolts of the base (1), support the rollers (2), the four sets of rollers (2) roll on the ring track on the cement foundation to rotate the double well pumping unit 180 degrees, turn the The two ends of the double well pumping unit are interchangeable.

[0014] As can be seen from the accompanying drawings, the support arm (4) with the runner (5) of the present invention is realized through the following technical proposals, on the double well pumping unit base (1) near the crank (3) side A support arm (4) has a runner (5) on ...

Abstract

The invention belongs to the field of twin-well oil pumping machine in the oil extraction machinery, and in particular relates to a rotary base arm crank bidirectional balancing twin-well pumping machine. The main technical proposal is as follows: a rotary base is provided so as to make the twin-well oil pumping machine rotate 180 degrees, thereby enabling two ends of the twin-well pumping machine to interchange, and making a well far away from a crank carry out workover operation and a well near the crank continue to work. An arm with a rotating wheel is arranged on one end of the oil pumping machine close to the crank. When the two wells are far away from each other, the arm can be extended to make the suspension point of the pumping machine aligned with the wells so as to adjust the distance of the suspension point of the pumping machine. During the workover, the arm is taken back, and the well on the other side continues to work.

Description

technical field [0001] The invention belongs to the field of pumping units in oil production machinery, and in particular relates to a two-way balanced double-well pumping unit with a rotating base support arm crank. Background technique [0002] At present, there are many oil production machines in various oil fields, one of which is a conventional beam pumping unit with double wells. Because the actual well spacing on site has certain differences, it is necessary to align the two oil wells on site; when the two oil wells are close, the crank The oil well workover range at the nearer end is limited, and the beam is too long when the two oil wells are far away, which requires a special structure for the pumping unit. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of the existing double-well pumping unit technology, to meet the different well spacings of conventional beam-type double-well pumping units, to provide a rotat...
