Abstract
The utility model relates to a pulse vibration source under a pump for a pumping well in an oil field, which comprises a central tube 2, a damping valve 4 connected to the lower surface of the central tube 2, etc. The utility model is characterized in that a damping vibration disk 3 is arranged on the outer wall of the central tube 2. The utility model has the advantages of simple structure, easy fabrication, convenient installation and long service life; when the utility model is used in various pumping wells, the utility model can generate definite pulse vibration without additional power and has the obvious effects of solving blocks and improving pumping efficiency and oil production.
Description
The utility model relates to a kind of oil field downhole tool, especially for the aid of pumpingh well deep well pump.
The pumpingh well that oil field oil recovery is at present produced all kinds of deep well pumps and tubing string that matches and the beam hanger posts of using more, this process structure in oil pumping process owing to be subjected to the variation of head of liquid in the oil pipe, tubing string and beam hanger post can produce the elastic deformation of axial cyclic, not only influence application life, also can cause the pump efficiency of deep well pump to descend; Simultaneously, deep well pump commonly used is not because its design feature generally has functions such as vibration unplugging raising capacity of oilwell.
The purpose of this utility model is can reduce obviously for pumpingh well production provides a kind of that tubing string and beam hanger axis of a cylinder prolong its application life to the amplitude of elastic deformation in the oil pumping process, improves the oil pumping pump efficiency; And the periodicity elastic deformation vibration force that can make tubing string is converted into and can acts on oil reservoir, pulse vibration source under the oil pumping well pump of generation plugging removal and stimulation effect.
The purpose of this utility model realizes by following measure: pulse vibration source under a kind of oil pumping well pump that is used for the oil field, comprise damping valve that central tube and its are connected below etc., the damping that it is characterized in that on the central tube outer wall of elongate tubular, being equipped with the disk shape dish that shakes.
The purpose of this utility model can also realize by following measure: the damping valve of pulse vibration source is oppositely installed for (the deep well pump standing valve is installed and flowed to relatively) under the oil pumping well pump.
The utility model processing and manufacturing simple in structure, easy, simple installation, life-span are long; When in all kinds of pumpingh wells, using, do not need additionaling power just can produce certain impulse oscillation, have the effect of tangible de-plugging, raising pump efficiency and oil production.
Fig. 1 is the structural representation of pulse vibration source under the oil pumping well pump.
The pulse vibration source is to be made of shake dish 3 and damping valve 4 etc. of central tube 2, damping under the oil pumping well pump.Also connect a relative deep well pump standing valve below the damping that a plurality of disk shapes are installed on central tube 2 outer walls of the elongate tubular dish 3 that shakes, central tube 2 and flow to the oppositely damping valve 4 of installation.
Using method of the present utility model and operating principle are: its central tube 2 upper ends are connected also together G.I.H with deep well pump 1 lower end; When in the manufacturing process during vibration of tubing string generating period, its axial vibration power is then by central tube 2, damping dish 3 liquid that pass in the oil well that shake, and remakes to be used for oil reservoir, reaches the purpose of vibration unplugging; Because damping valve 4 is oppositely to install, when the piston stroking upward tubing string generation axial elasticity of deep well pump 1 shrinks, its unlatching can increase the fluid course that enters in the pump, and when the descent of piston tubing string generation axial elasticity of deep well pump 1 extended, it is closed can increase damping action; Dish 3 is less with sleeve pipe 5 gaps because damping is shaken, and can produce very strong damping vibration attenuation function in the tubing string vibration process, thereby reaches the purpose that reduces tubing string and beam hanger post elastic deformation amplitude and improve the oil pumping pump efficiency.
