Abstract
The utility model discloses a short pump-barrel long-piston tube type oil pump which unloads oil automatically and is less than or equal to Phi57mm. The utility model comprises an upper joint 1, a long piston 2, a sealing pump barrel 3, a diameter-expanding pump barrel , a moving walk valve 7,and a fixed valve 8, wherein a moving valve 7 is respectively arranged fixedly at upper and lower ends of the long piston 2, a sealing pump barrel 3 is connected fixedly with the upper joint 1, the lower end of the sealing pump barrel 3 is connected fixedly with the diameter-expanding pump barrel 6, the lower end of the diameter-expanding pump barrel 6 is connected fixedly with the fixed valve 8, the wall of the sealing pump barrel 3 is provided with an oil leakage opening 4. The oil pump can play the role of pumping oil dueing normal production and also play the role of oil discharge when performing construction of well string. The utility model has the advantages of protecting environment, improving well field operation condition, reducing emission and increasing efficiency.
Description
Technical field:
The utility model instrument relates to a kind of employed downhole tool when recovering the oil for the oil field development pumping well.
Background technique:
For realizing cleaning operation, reduce ground pollution in oilfield downhole operation construction, improve the job execution environment, especially nearly 2 years countries and enterprise are to the great attention of environmental protection, and normally the use oil drainer solves foregoing problems on down-hole string.But present employed oil drainer is in use unreliable, exist do not open, the problem of draining etc. in the production process, and more complicated is gone up in operation.
The model utility content:
In order to solve existing technical problem in the background technique, the utility model instrument provides a kind of easy and simple to handle, practical tubing pump of draining automatically.
For solving the problems of the technologies described above, the short pump barrel long-plunger tubing pump of draining automatically of the present utility model, its specification is smaller or equal to 57mm, comprise upper connection, long-plunger, sealing pump barrel, hole enlargement pump barrel, travelling valve, standing valve, long-plunger a travelling valve respectively arranged up and down, the sealing pump barrel is fixedlyed connected with upper connection, seals the fixedly connected hole enlargement pump barrel in lower end of pump barrel, fixedlying connected with standing valve in the lower end of hole enlargement pump barrel, is provided with drain tap on the wall of sealing pump barrel.
The working principle of this model utility is: this patent is cancelled the oil drainer on original tubing string, the oil drainer function is transferred on the short pump barrel long-plunger oil well pump, promptly on the sealing pump barrel, open the draining hole, utilize long-plunger and sealing pump barrel can realize clearance seal, thereby when guaranteeing the oil well pump proper functioning, the draining hole does not influence the sealing of oil well pump.During job execution, trip out rod string and plunger, expose the draining hole, pump barrel plays the effect of oil drainer, and this is a kind of 100% reliable " oil drainer ".
The utility model instrument has following beneficial effect:
1, oil well pump and oil drainer combine, and play the oil pumping effect during oil well pump ordinary production, play the draining effect when job execution plays former well casing post, have the protection environment, improve the wellsite operation condition, reduce discharging synergistic effect; Compare 100% safe and reliablely with oil drainer, do not have hidden danger of quality;
2, novel structure; Simple to operate, there is not additional move;
3, the long-plunger short pump barrel has the effect of prevention plunger sand card.
4, long-plunger is proposed pump barrel, can realize the direct flushing wax removal, have the wax removal of raising effect, reduce the effect of oil layer pollution.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-upper connection, the 2-long-plunger, 3-seals pump barrel, the 4-drain tap, 5-becomes head, 6-hole enlargement pump barrel, 7-travelling valve, 8-standing valve
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the short pump barrel long-plunger tubing pump of draining automatically of the present utility model comprises upper connection (1), long-plunger (2), sealing pump barrel (3), hole enlargement pump barrel (6), travelling valve (7), standing valve (8), long-plunger (2) a travelling valve (7) respectively arranged up and down, sealing pump barrel (3) is fixedlyed connected with joint (1), the fixedly connected hole enlargement pump barrel in lower end (6) of sealing pump barrel (3), can connect by becoming head (5), fixedlying connected with standing valve (8) in the lower end of hole enlargement pump barrel (6), is provided with drain tap (4) on the wall of sealing pump barrel (3).
The short pump barrel long-plunger tubing pump of the application's draining automatically is when work, long-plunger (2) work in sealing pump barrel (3) all the time, and seal the draining hole (4) on the pump barrel all the time, long-plunger (2) is in clearance seal with sealing pump barrel (3), guarantees the oil well pump proper functioning; When the operation construction tripped out the long-plunger roofbolt, the draining effect was just played in the draining hole (4) on the pump barrel.
Claims (2)
1. short pump barrel long-plunger tubing pump of draining automatically, its specification is smaller or equal to 57mm, comprise upper connection (1), long-plunger (2), sealing pump barrel (3), hole enlargement pump barrel (6), travelling valve (7), standing valve (8), long-plunger (2) a travelling valve (7) respectively arranged up and down, sealing pump barrel (3) is fixedlyed connected with upper connection (1), the fixedly connected hole enlargement pump barrel in lower end (6) of sealing pump barrel (3), fixedlying connected with standing valve (8) in the lower end of hole enlargement pump barrel (6), it is characterized in that: be provided with drain tap (4) on the wall of sealing pump barrel (3).
2. according to the short pump barrel long-plunger tubing pump of the described draining automatically of claim 1, it is characterized in that: described sealing pump barrel (3) is connected by becoming head (5) with hole enlargement pump barrel (6).
