The underground direct-current electromagnetic pump double-cylinder oil production device comprises an oil storage pipe body, wherein the oil storage pipe body is connected with a left mounting pipe body and a right mounting pipe body; a left electromagnetic coil is arranged at the bottom of the left mounting pipe body, a left static magnet is arranged at the center of the left electromagnetic coil; a left movable assembly is arranged over the left static magnet and comprises a left movable magnet and a left plunger structure; a right electromagnetic coil is arranged at the bottom of the right mounting pipe body; a right static magnet is arranged at the center of the right electromagnetic coil; a right movable assembly is arranged over the right static magnet and comprises a right movable magnet and a right plunger structure; and an opening is formed between the left mounting pipe body and the right mounting pipe body and communicates with a lower left compression cavity and a lower right compression cavity. The device has the advantages of long-distance direct-current power supply transmission, energy conservation, loss reduction and improvement of crude oil recovery efficiency.

Description

technical field [0001] The invention relates to the technical field of underground oil production equipment, in particular to an underground DC electromagnetic pump double-cylinder oil production device. Background technique [0002] Oil extraction refers to the act of digging and extracting oil in places where oil is stored. Most of the current oil production methods are large-scale pumping units erected on the ground, which are connected to oil layer pumps several kilometers deep underground through long and heavy sucker rods. Since the pumping units are installed on the ground, they are large in size and occupy a lot of land. In addition, the sucker rod connected to the deep reservoir pump thousands of meters underground has long-term friction or even collision with the tubing wall during operation. Ten tons, low mechanical efficiency, high loss, requires a large drive motor and power supply, each well must set up high-voltage power lines, transformers and other faciliti...

Problems solved by technology

Most of the current oil production methods are large-scale pumping units erected on the ground, which are connected to oil layer pumps several kilometers deep underground through long and heavy sucker rods. Since the pumping units are installed on the ground, they are large in size and occupy a lot of land. In addition, the sucker rod connected to the deep reservoir pump thousands of meters underground has long-term friction or even collision with the tubing wall during operation. 10 tons, low mechanical efficiency, high loss, large drive motor and power supply are required, and high-voltage power lines must be erected for each well, and facilities such as transformers must be installed

With the development and progress of society, the country has higher and higher requirements for environmental protection. This oil extraction method highlights many disadvantages. First, the structure of large pumping units is complex and heavy, and there are many unsafe factors during operation. Accidents such as machine injuries occurred, followed by factors such as a large amount of friction loss between the sucker rod and the oil pipe wall, the polished rod and the packing, the beam, the gearbox, and the imbalance of the counterweight during the operation of the pumping unit. The mechanical efficiency is extremely low, which leads to waste of driving energy, resulting in a low oil recovery rate, which cannot meet the needs. Finally, there is a lot of noise pollution during the operation process, accompanied by the leakage of flammable, explosive and other harmful gases. It is a serious challenge to the development of civilization in today's society
