Abstract
This utility model relates to a tubing deep well oil-well pump booster utilized in the oil pumping production in oil field, comprising an upper adapter 1, an upper mandrel 2, an upper plunger 3, a connection coupling 4, a crossover sub 5, an upper grinding ball 6, an upper tee 7, an upper tee support ring 8, a ball shield 9, a lower plunger 10, a lower grinding ball 11, a lower tee 12, a lower tee support ring 13, a lower mandrel 14, an energy-storage spring 15 and a lower adaptor 16. The structure and assembling relation is that the upper and lower ends of the upper mandrel 2 are connected with the upper adapter 1 and the connection coupling 4 via screw thread, the upper and lower ends of the lower mandrel 14 are respectively connected with the connection coupling 4 and the upper adaptor 16, the upper plunger 3 is arranged in the upper mandrel 2 and the coupling 4, the lower end of the upper plunger 3 is connected with the crossover sub 5 which is provided with the upper grinding ball 6, the upper tee 7, the upper tee support ring 8 and the ball shield 9,the ball shield 9 is connected with the lower plunger 10 via screw thread, the lower plunger 10 is provided with the lower grinding ball 11, the lower tee 12 and the lower tee support ring 13, and the energy-storage spring 15 is arranged within the lower mandrel 14. This device is simple in structure, reliable in working and utilizing this device can improve crude oil pump-in pressure, efficiency of pump and crude oil output.
Description
Technical field:
The utility model relates to a kind of downhole hardware that oil field pumping well is produced that is used for, and belongs to mechanical oil recovery down-hole instrument class.
Background technique:
Tubing pump be the on-the-spot pumping well in oil field traditionally and one of main oil well pump that adopts at present because the advantage of this kind oil well pump self, can satisfy the needs of most of oil well ordinary production.Yet the oil well too low for some formation pressures, that the pit shaft producing fluid level is darker causes pump efficiency not high because of the pump barrel filling index is low, makes oil well output and ordinary production be affected.
Summary of the invention:
The utility model purpose is to provide a kind of can improve the tubular type deep-well oil pump pressurized machine that crude oil advances pumping pressure, pump barrel filling index and oil pumping pump efficiency.
The utility model purpose is to realize like this.This kind pressurized machine is made up of upper and lower joint, upper and lower working barrel, upper and lower plunger, connection box cupling, crossover sub, upper and lower valve ball, upper and lower ball seat, upper and lower ball seat support ring, the cover of blocking, energy storage spring, last working barrel upper and lower end respectively with screw thread and upper connection be connected box cupling and be connected, following working barrel upper and lower end respectively be connected box cupling and be connected with lower contact; Be provided with upper plug in the last working barrel, the plunger lower end is connected to crossover sub, be provided with valve, upper ball base, upper ball base support ring and the cover of blocking in the crossover sub, the cover of blocking is connected with lower plunger with screw thread, be provided with down valve ball, lower ball base and lower ball base support ring in the lower plunger, be provided with energy storage spring in the following working barrel.During underground work, this device is hinged with on tubing string below the tubing pump down to the downhole designs degree of depth.After pumping unit starts, drive upper plug during the oil pump plunger piston down stroke and lower plunger moves down, and the compressed energy-storage spring, the mechanical energy that plunger is done when descending is converted into the elastic potential energy of pressurized machine; When plunger was up, energy storage spring released energy, and the plunger suction force is increased, and advanced pumping pressure and pump barrel filling index thereby improve crude oil, reached the purpose that improves tubing pump pump efficiency and crude output by the short stream effect of supercharging.
The utility model is rational in infrastructure, and reliable operation is utilized it can improve crude oil and advanced pumping pressure and pump barrel filling index, improves pump efficiency and crude output, is suitable for and applies.
