Problems solved by technology

Although the beam pumping unit has a long history of use, it has been a difficult problem in the oil production industry for many years due to its high energy consumption. The CYJ5-2712 beam pumping unit used for oil wells with a depth of 1400 meters is an example. For example, the suspension point load at the head of the donkey is 5800 kg (including the weight of the sucker rod of 2800 kg and the weight of the liquid column on the plunger pump of 3000 kg), and the power of the motor is as high as 17KW

Abstract

The invention provides a level type oil pumping unit which is controlled by a counter weight machine and comprises a bracket, a walking beam, a mule head, a polished rod eye, a drilling template packing box and an oil outlet three-way. The level type oil pumping unit is characterized in that the right end of the walking beam is provided with a counter weight and a pulley block which is connected with the counter weight and consists of a movable pulley, a fixed pulley and an angle pulley; and the pulley block is connected with a winch through a steel wire rope. The oil pumping unit with the structure has simple structure and low cost and is very energy-saving.

Description

technical field [0001] The invention relates to oil exploitation equipment, in particular to a heavy hammer mechanically controlled lever type oil pumping unit. Background technique [0002] The pumping unit is powered by an electric motor, which converts the motor's rotational motion into a vertical reciprocating motion, and then transmits the reciprocating motion to the downhole plunger oil pump through the sucker rod, so as to achieve the purpose of pumping underground crude oil. [0003] At present, beam pumping units are widely used in oilfields at home and abroad. Composition, the rotary motion of the motor is converted into the reciprocating motion of the sucker rod through the crank-link mechanism to achieve the purpose of pumping oil. Although the beam pumping unit has a long history of use, it has been a difficult problem in the oil production industry for many years due to its high energy consumption. The CYJ5-2712 beam pumping unit used for oil wells with a dept...
