Integrated pumping unit

Abstract

The invention discloses an integrated oil pumping device, which consists of an oil pumping device, a power transmission device and a pit shaft device. The device is characterized in that the circular motion centered with an output shaft is made by a crank and a movable pulley that is on the crank to lead to the reciprocating motion of the flexible-transmission elements in the wellhead, thereby the regionality can be realized. The oil pumping machine can drive a plurality of oil wells within the distance of 50-100 meters to pump oil, leading to the multifunction of one machine and regional oil production, and has the advantages of improving the system efficiency, simplifying and compacting the structure, reducing the weight and volume of the oil pumping machine, saving the energy and consumption and requiring little invested installment.

Description

Technical field: [0001] The invention relates to an oil mining machine, in particular to an integrated crank pumping unit. Background technique: [0002] The international energy supply situation is becoming increasingly tense, and China's crude oil imports are increasing year by year; national economic development has higher requirements for energy and energy consumption. In the new century, the world advocates entering a harmonious society and developing safe, energy-saving, and green production processes. With the development of oil fields and the continuous development of technology, there are various types of mechanical oil recovery equipment ranging from beam pumping units to beamless pumping units to meet the needs of different production periods. At present, 75% of the pumping units used for artificial lifting are mainly beam pumping units, which can be divided into conventional beam pumping units and front-mounted pumping units according to the structure of the four...

Problems solved by technology

[0003] Aiming at the problems of poor motion performance of existing pumping units, low utilization rate of single-unit and single-well equipment, inability to balance each other, large load fluctuations, etc., the present invention provides an integrated pumping center system for residential areas. The pumping unit uses light flexible ropes as the main line. Instead of the original rigid energy transfer structure, one pumping unit drives multiple wells within 50-100m around to pump oil at the same time through the pulley block, realizing one machine with multiple functions and regional oil production; there is no special balance block, which reduces the weight of the pumping unit , can automatically balance each other through the load change of each oil well; reliable own power, pump operation, testing and other functions; integrated, well, mechanical balance, reasonable, the system is more compact, and the volume is reduced several times; it can be used Realize continuous oil pumping
