Abstract
The utility model provides an oil-well pump of steam injection with eccentric-valve style, comprising an on-pump coupling, a plunger coupling, an inner rod of a plunger, a plunger, an oil-outlet valve, a valve body, a valve ball and a valve base. A plunger barrel is assembled with a valve sleeve. The utility model is characterized in that the valve employs eccentric construction, a sliding sleeve is installed inside the valve body, a rotating rod is provided on the lateral side of the valve sleeve, and the lower portion of the rotating rod is connected with a leverage which is engaged with the valve ball arranged inside the valve body. The valve ball sitting on the valve base can open the valve ball to inject steam to the oil layer without additional apparatus in the need of injecting steam to the oil layer, thereby lowering the labor strength of the workers, saving operation time, improving economy efficiency and also avoiding environmental pollution caused by frequent operation.
Description
The utility model belongs to a kind of petroleum production machinery, specifically is that a kind of centralized procurement oil and notes vapour are the eccentric valve type notes vapour oil well pump of one.
When oil recovery industry in oil field is coagulated the problem of the mobile difference of oil reservoir at solution viscous crude and height, generally all use special device, take to inject the method for high-temperature vapor with the oil reservoir heating to oil reservoir, improve the temperature of oil reservoir, reduce its viscosity, make it to flow easily, be convenient to extraction from oil well, this technology construction operation step is many, the cost of production height.
The purpose of this utility model is that a kind of eccentric valve type that can be suitable for injection steam in oil well again of can pumping when normal oil recovery of design is annotated the vapour oil well pump to solve the problem to the oil reservoir heating.
The purpose of this utility model is to realize like this, it is made up of bar, pump barrel, plunger, outlet valve, valve body, valve ball, valve seat in box cupling, plunger box cupling, the plunger on the pump, pump barrel and valve pocket assembling, its feature is that valve body adopts the eccentric structure, and flip sleeve is installed in valve body, and valve bonnet is installed in the sliding sleeve lower end, drive link is equipped with in the valve bonnet side, connect leverage under the drive link, the valve ball in leverage and the valve body cooperates, and valve ball is sitting on the valve seat.
Concrete structure of the present utility model has, and leverage is made up of lever, bearing pin, spring, and porose corresponding with bearing pin on the lever, an end of lever is equipped with spring, and bearing pin is fixed on the valve body.
The utility model is owing to adopt eccentric at valve body, one leverage is installed in valve body, make its at needs when oil well injects steam, can open valve ball and inject steam to oil reservoir, need not other equipment, reduce working strength of workers, save the activity duration, increase economic efficiency, but also the environmental pollution that can avoid frequent operation to cause.
Below in conjunction with accompanying drawing a specific embodiment of the present utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure: the utility model is by box cupling on the pump 1, plunger box cupling 4, bar 7, pump barrel 3, plunger 6, outlet valve 9, valve body 10, valve ball 15 valve seats 16 are formed in the plunger, sucker rod 2 takes on and is installed in the pump barrel 3 after fuel tap 9 assembles with plunger 6, pump barrel 3 and valve body 10 assemblings, be characterized in that valve body adopts the eccentric structure, flip sleeve 11 is installed in valve body, valve bonnet 13 is installed in sliding sleeve 11 lower ends, drive link 12 is equipped with in valve bonnet 13 sides, drive link connects leverage 12 times, valve ball 15 in leverage and the valve body cooperates, and valve ball 15 is sitting on the valve seat 16.
Leverage is made up of lever 14, bearing pin, spring 17, and porose corresponding with bearing pin on the lever 14, an end of lever 14 is equipped with spring 17, and bearing pin is fixed on the valve body.
When the utility model normally recovers the oil, its function is identical with normal oil extraction pump, when needs when oil well is annotated vapour, sucker rod and plunger are descending, outlet valve is in opening state, the descending continuation of sucker rod and plunger is descending, be pressed onto flip sleeve 11, when plunger is pressed onto flip sleeve 11, press drive link, the lever rotation of its leverage is levered up valve ball, make its valve ball 15 lift off a seat 16, standing valve and outlet valve all are in opening state like this, have guaranteed that oil well pump communicates up and down, just can inject steam heating in oil well.Notes vapour finishes, and upwards mentions sucker rod, because the effect of spring, with lever, drive link, flip sleeve jack-up, the valve ball return recovers normal oil recovery state.
