Abstract
A horizontal well relay pump lift device of the utility model mainly solves the problem of close lagging of the ball seat, descent lagging of the sucker rod, and the eccentric wear and air lock of the rod and tube. The utility model is characterized in that the bottom of the oil tube (2) connects with a first level oil-well pump (3) in the inclined well section. The bottom of the plunger in the first level oil-well pump (3) connects via a sucker rod (1) with a secondary level oil-well pump (4) whose bottom is provided with a gas proof anchor (6). The secondary level oil-well pump (4) is an oil-well pump with big grade of slope. The outsides of the sucker rod (1) and the secondary level oil-well pump (4) are both provided with centralizers (5). The horizontal well relay pump lift device can meet the requirement of deep pumping of horizontal well. The ball seat of the oil-well pump closes in time, and the sucker rod descends in time. The phenomena of eccentric wear and air lock of the rod and tube does not occur.
Description
Technical field:
The utility model relates to down-hole crude oil lift device, especially horizontal well booster pump lift device in the oil recovery field, oil field.
Background technique:
In the oil recovery process of oil field, in horizontal well lifting process, the problem that need to solve is how to realize that horizontal well depth takes out, and reduces horizontal well stream and presses, the performance oil well productivity.Present rod pump lifting oil production method, though technology maturation, when conventional oil well pump was worked, the inclination angle of oil well pump can not be greater than 40 °, exist the oil well pump ball seat to close the problem of hysteresis, the descending hysteresis of sucker rod, bar and pipe eccentric wear, gas lock, can't satisfy the requirement that horizontal well depth is taken out.
The model utility content:
Close the problem of hysteresis, the descending hysteresis of sucker rod, bar and pipe eccentric wear, gas lock in order to solve existing oil well pump ball seat, the utility model provides a kind of horizontal well booster pump lift device, this horizontal well booster pump lift device can satisfy the requirement that horizontal well depth is taken out, the oil well pump ball seat is closed in time, sucker rod is descending also timely, bar and pipe do not produce eccentric wear, can not produce the gas lock phenomenon yet.
The technical solution of the utility model is: this horizontal well booster pump lift device comprises sucker rod, oil pipe and I and II oil well pump, oil pipe connects the one-level oil well pump in the lower curved section down, plunger below in the one-level oil well pump connects the secondary oil well pump that anti-gas anchor is equipped with in the below by sucker rod, the secondary oil well pump is big gradient oil well pump, and sucker rod and secondary oil well pump all are equipped with centralizer outward.
The inclination angle of above-mentioned one-level oil well pump is 18 °～22 °; The inclination angle of secondary oil well pump is 48 °～52 °.
The utlity model has following beneficial effect: owing to take the secondary oil well pump of such scheme is big gradient oil well pump, and valve can in time be closed, and has avoided the oil well pump ball seat to close hysteresis; Utilize sucker rod to be rigidly connected between the I and II oil well pump, make the action of I and II oil well pump synchronously, also can not lag behind when sucker rod is descending simultaneously; The anti-gas anchor that be equipped with secondary oil well pump below can prevent effectively that gas from entering in the pump barrel of I and II oil well pump, guarantees I and II oil well pump proper functioning; Sucker rod and secondary oil well pump all are equipped with centralizer outward, have avoided bar, pipe eccentric wear, have also prevented the swing of secondary oil well pump simultaneously.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-sucker rod among the figure, the 2-oil pipe, 3-one-level oil well pump, 4-secondary oil well pump, the 5-centralizer, 6-prevents gas anchor.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, this horizontal well booster pump lift device comprises sucker rod 1, oil pipe 2 and I and II oil well pump (3,4), the one-level oil well pump 3 that oil pipe connects in the lower curved section for 2 times, and the inclination angle of one-level oil well pump 3 is 18 °～22 °.Plunger below in the one-level oil well pump 3 connects the secondary oil well pump 4 that anti-gas anchor 6 is equipped with in the below by sucker rod 1, utilize sucker rod 1 to be rigidly connected between the I and II oil well pump (3,4), make I and II oil well pump (3,4) action can not lag behind when sucker rod 1 is descending simultaneously synchronously yet; Anti-gas anchor 6 can prevent effectively that gas from entering in the pump barrel of I and II oil well pump (3,4), guarantees I and II oil well pump (3,4) proper functioning; Secondary oil well pump 4 is big gradient oil well pump, generally be that the pump of gradient above 40 ° is called big gradient pump, the characteristics of big gradient pump are that the valve of pump is positive closing, and the inclination angle of secondary oil well pump 4 is 48 °～52 °, valve can in time be closed, avoided the oil well pump ball seat to close hysteresis; All be equipped with centralizer 5 outside sucker rod 1 and the secondary oil well pump 4, avoided bar, pipe eccentric wear, also prevented the swing of secondary oil well pump 4 simultaneously.
Claims (3)
1, a kind of horizontal well booster pump lift device, comprise sucker rod (1), oil pipe (2) and I and II oil well pump (3,4), it is characterized in that: oil pipe (2) connects the one-level oil well pump (3) in the lower curved section down, plunger below in the one-level oil well pump (3) connects the secondary oil well pump (4) that anti-gas anchor (6) is equipped with in the below by sucker rod (1), secondary oil well pump (4) is big gradient oil well pump, the outer centralizer (5) that all is equipped with of sucker rod (1) and secondary oil well pump (4).
