Abstract
A synergism oil-pumping device consists of a valve sleeve, a seal polished rod, a screwed valve sleeve, a pressure relief valve seat, a valve seat joint, an oil well pump working barrel and an oil well pump piston assembly. The oil well pump piston assembly is located in the oil well pump working barrel. The pressure relief valve seat is installed above the lower thread of the valve sleeve; wherein the lower thread of the valve sleeve is connected with the upper thread of the valve seat joint and the lower part of the valve seat joint is connected with the upper part of the oil well pump working barrel. The screwed valve sleeve is arranged outside of the seal polished rod and is located on the pressure relief valve seat. The lower part of the seal polished rod is connected with the oil well pump piston assembly. When pumping, fluid column pressure acts on the screwed valve sleeve and is transferred to the pressure relief valve seat. Thus, the device results in reducing of the load on the seal polished rod and achieving the purposes of reducing the load of oil pumping, reducing energy consumption, prolonging the service life of oil pumping tools, having long production period of the oil well and enhancing economic efficiency of the oil well.
Description
One, technical field
The utility model relates to a kind of device of oil field oil recovery usefulness, particularly a kind of synergy oil rig.
Two, background technology
In oil field pumping well, along with continuous exploitation, energy drain, liquid level descends, in order to keep production, having only increases the pump degree of depth down, causes pump efficiency to descend, and the oil pumping load increases, energy consumption increases, the pumping tool lost of life, and the oil well production cycle is short, the maintenance cost height.
Three, summary of the invention
The purpose of this utility model is a kind of synergy oil rig of design, reduces the pressure on oil well pump top, reduces the oil pumping load, reduces energy consumption.
The purpose of this utility model is achieved in that and comprises oil well pump seating nipple, oil well pump piston assembly, the oil well pump piston assembly is in the oil well pump seating nipple, also form by valve pocket, sealing polished rod, spiral valve pocket, Pressure relief valve seat, valve base joint, Pressure relief valve seat is installed on the valve pocket lower thread, the valve pocket lower thread is threaded with valve base joint top, the valve base joint bottom is connected with oil well pump seating nipple top, the screw valve cover is sleeved on outside the sealing polished rod, the screw valve cover is located on the Pressure relief valve seat, and sealing polished rod bottom is connected with the oil well pump piston assembly.
The beneficial effects of the utility model are: can reduce the pressure on oil well pump top, reduce the oil pumping load, reduce energy consumption, prolong the application life of pumping tool, the oil well production cycle is long, improves the economic benefit of pumpingh well.
Four, description of drawings
Accompanying drawing is an assembling drawing of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, to embodiment of the present utility model by valve pocket 1, sealing polished rod 2, spiral valve pocket 3, Pressure relief valve seat 4, valve base joint 5, oil well pump seating nipple 6, oil well pump piston assembly 7 is formed, oil well pump piston assembly 7 is in the oil well pump seating nipple 6, Pressure relief valve seat 4 is installed on valve pocket 1 lower thread, valve pocket 1 lower thread is threaded with valve base joint 5 tops, valve base joint 5 bottoms are connected with oil well pump seating nipple 6 tops, spiral valve pocket 3 is sleeved on outside the sealing polished rod 2, spiral valve pocket 3 is located on the Pressure relief valve seat 4, and sealing polished rod 2 bottoms are connected with oil well pump piston assembly 7.Spiral valve pocket 3 external surfaces have helical duct.
During work, sealing polished rod 2 is up, and it is up to drive oil well pump piston assembly 7, and the space between oil well pump piston assembly 7 and the spiral valve pocket 3 reduces, and the spiral valve pocket is backed down, and the well liquid of extraction enters on the pump oil pipe by extraction through the helical duct of spiral valve pocket 3 external surfaces.Sealing polished rod 2 is descending, oil well pump piston assembly 7 is also descending, and the space between oil well pump piston assembly 7 and the spiral valve pocket 3 increases, and pressure descends immediately, blow off valve news speed in the oil well pump piston assembly 7 is opened, and the well liquid of oil well pump piston assembly 7 bottoms just can not drained on the pump by compression.
During oil pumping, head of liquid acts on the spiral valve pocket 3, and is transferred on the Pressure relief valve seat 4, thereby the load on the sealing polished rod 2 is reduced, reach and reduce the oil pumping load, reduce energy consumption, prolong the application life of pumping tool, the oil well production cycle is long, improves the purpose of the economic benefit of pumpingh well.
The utility model is except that having above characteristics, and also having the associated gas that prevents in the well liquid influences the oil well pump pump efficiency, prevents the characteristics of holddown after sand sinks down on the pump on the pump, also can increase the pump degree of depth down.
