There are problems that some shortcomings such as intrinsic eccentric wear part between oil pipe.The intensification hung with the rising of oil-field aqueous, pump and spy
Different track well increases, and this problem becomes increasingly severe.Secondly, excessive transmission link, overcome sucker rod weight in itself
And elastic deformation will consume a part of power, ultimately result in the reduction of oil pumper sucker rod pumping system efficiency, maintenance workload and increase, increase
Crude oil production cost is added.
Oil immersion line motor Rodless oil extraction integrated apparatus of the present invention are that permanent-magnetism linear motor is placed in into underground, are led to
Cross the mechanical energy that magnetic pumping converts electrical energy into electric mover, the barrier film assembly on the mover connection motor top of motor, it is not necessary to
The transmission device of any intermediate conversion mechanism, so that directly driving barrier film assembly realizes that crude oil is lifted.Adopted with oil pumper sucker rod pump
Oil system is compared, and due to not needing sucker rod, eliminates loss of plunger stroke, improves pumping efficiency of oil pump and running efficiency of system, drop
Low energy consumption, also fundamentally solves the problems, such as the rod and tube partial-wear of directional well generally existing, reduce later stage operation expense and
Labour intensity;System above ground portion only has switch board, and well head floor space is few.
