Abstract

The invention discloses efficient permanent magnet motor direct-drive screw pump oil mining and transporting equipment and belongs to the field of oil mining equipment. The efficient permanent magnet motor direct-drive screw pump oil mining and transporting equipment comprises a screw pump component (9) and is characterized in that a bottom centralizer (1), an efficient permanent magnetic submersible electric unit, a serial bearing pack and a bidirectional thrust universal coupler (6) are sequentially mounted at the lower portion of the screw pump component (9) from bottom to top, an oil delivery pipe (17) is connected to the upper portion of the screw pump component (9), a plurality of valve components are mounted in the oil delivery pipe (17), and the upper end of the oil delivery pipe (17) is connected with surface equipment. By the arrangement, reliability and transmission efficiency of products can be greatly improved, service life of the equipment is prolonged, bearing force is high, and requirements on high delivery lift and large displacement units are met.

Description

technical field [0001] The utility model relates to a high-efficiency permanent magnet motor direct-driven screw pump oil extraction and transportation equipment, which belongs to the field of oil extraction equipment. Background technique [0002] In the rod production system, problems such as sucker rod wear, sucker rod breakage, sucker rod tripping, and oil pipeline wear have always been a major problem that plagues the reliability of oil production systems in oilfields. At the same time, ground-driven oil production equipment has the disadvantages of large footprint, high noise, leakage, and heavy daily maintenance workload. Safety in densely populated areas is also an issue. In order to solve the above problems, submersible screw pump oil recovery technology has gradually emerged worldwide. However, due to the unreasonable design of the bearing system, coupling system and other structural aspects of the electric submersible screw pump in the prior art, the equipment h...
