Abstract
The utility model discloses a rod type oil well pump for oil production of oil fields. The rod type oil well pump comprises a pump cylinder, a solid plunger, an outer pipe, an oil outlet valve, an oil inlet valve, a sealing fixation device and a sand setting tap. The outer pipe and the sand setting tap are put into a well along with an oil pipe on the pump, then the pump cylinder, the solid plunger, the oil outlet valve, the oil inlet valve and the sealing fixation device are put into the outer pipe along with a sucker rod, and the sealing fixation device is pressed into an upper hole of the sand setting tap under the action of the weight of the sucker rod, and then the oil well pump can work. The plunger is solid, and crude oil does not flow in the plunger, so that a flow channel is changed; the oil outlet valve is not arranged on the plunger, so that the diameter of a valve ball of the oil outlet valve is not limited by the diameter of the pump, the diameter of the valve ball can be increased, and the mass of the valve ball is increased; therefore, the valve ball works flexibly and the rod type oil well pump works reliably; and a sand setting channel is formed, so a pump core cannot be buried by sand, and the pump inspection can also be successfully performed when the rod type oil well pump is used on a sand well.
Description
Technical field
The utility model is a kind of oil well pump of oil field oil recovery usefulness, is a kind of rod-type pumping unit.
Background technique
The pump barrel of rod-type pumping unit and oiling valve can be lowered to or be proposed by sucker rod, and therefore, the well of following rod-type pumping unit only needs to propose the purpose that whole sucker rods just can be realized the inspection pump when operation inspection pump; Need not propose oil pipe, the work operations amount is few, and the darker oil well of following pump more can embody its superiority, but the darker oil well of pump generally all is the very low oil well of oil output down; Under oil well pump also less, in existing rod-type pumping unit, all be that outlet valve is installed on plunger; Fluid passes through from plunger, when the oil well pump diameter hour, receive size restrictions; Valve ball, runner are less, and valve ball can be malfunctioning, causes air pump inoperative.When sand production, sand holddown tube can appear, sucker rod and pump core inspection pump can't be proposed.
Summary of the invention
The purpose of the utility model is a kind of rod-type pumping unit of design, makes its valve ball diameter not receive the oil well pump diameter restrictions through changing runner, can increase the valve ball diameter; Improve the reliability of rod-type pumping unit; Be provided with the sand setting passage, sand can not bury the pump core, on sand output well, uses can propose to examine pump smoothly yet.
The purpose of the utility model is achieved in that and comprises by pump barrel, solid plunger, outer tube, outlet valve, oiling valve, sealed fixing device, sand setting tap; The outer tube bottom connects with sand setting tap major thread; Pump barrel, solid plunger, outlet valve, oiling valve, sealed fixing device connect successively from top to bottom and are in the outer tube, and sealed fixing device is installed in the sand setting tap upper hole.Solid plunger cooperates with pump barrel and seals.Outer tube top connects oil pipe on the pump, and solid plunger upper part connects sucker rod.
The beneficial effect of the utility model is: plunger is solid, and crude oil does not flow in plunger, has changed runner; Uneasiness takes on fuel tap on the plunger, makes its valve ball diameter not receive the pump diameter restrictions, can increase the valve ball diameter; The valve ball quality increases, thereby valve ball work is flexible, the rod-type pumping unit reliable operation; Because be provided with the sand setting passage, sand can not bury the pump core, on sand output well, uses can propose to examine pump smoothly yet.
Description of drawings
Fig. 1 is the utility model embodiment erection drawing.
Embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
Can know that by figure the embodiment of the utility model comprises pump barrel 1, solid plunger 2, outer tube 3, outlet valve 4, oiling valve 5, sealed fixing device 6, sand setting tap 7.Outer tube 3 bottoms connect with sand setting tap 7 major threads; Pump barrel 1, solid plunger 2, outlet valve 4, oiling valve 5, sealed fixing device 6 connect successively from top to bottom and are in the outer tube 3; Sealed fixing device 6 is installed in sand setting tap 7 upper holes, and solid plunger 2 cooperates with pump barrel 1 and seals.Outer tube 3 tops connect oil pipe on the pump, and solid plunger 2 tops connect sucker rod.
Outer tube 3, sand setting tap 7 are earlier with oil pipe G.I.H on the pump; Pump barrel 1, solid plunger 2, outlet valve 4, oiling valve 5, sealed fixing device 6 are lowered in the outer tube 3 with sucker rod again; Under the rod weight effect; Sealed fixing device 6 is pressed in sand setting tap 6 upper holes, and oil well pump just can be worked.Sucker rod drives solid plunger 2 when up; The cavity volume of solid plunger 2 bottoms increases; Pressure in it descends, and oiling valve 5 is opened, and crude oil gets in the cavity of solid plunger 2 bottoms through the lateral access 8 of sand setting tap 7, oiling valve 5 and outlet valve 4 in the well.Sucker rod drives solid plunger 2 when descending; The cavity volume of solid plunger 2 bottoms reduces; Pressure in it rises; Oiling valve 5 cuts out, and the crude oil in the cavity is upwards opened the annular space that outlet valve 4 is expelled to outlet valve 4 and outer tube 3 from the central passage 9 of outlet valve 5 downwards again through the lateral access 8 of outlet valve 4, is discharged to ground then.Sand on the pump in the liquid separate after the annular space of pump barrel 1 and outer tube 3 through sand setting tap 7 to being lowered into tail pipe under the pump, thereby wall is exempted from the sand card, sand buries solid plunger 2.
