Abstract
The utility model relates to an oil well pump for construction and operation in an oil field, in particular to a long plunger type anti-sand oil well pump. The technical proposal is as follows: the oil well pump comprises a long plunger, a short pump cylinder, a flow channel body, a lower joint, an oil inlet valve, an oil outlet valve, a release packer and a sand filtration tube; the upper end of the long plunger is provided with an upper oil outlet valve and the lower end thereof is provided with a lower oil outlet valve; the upper end of a lengthened inner cylinder is provided with the short pump cylinder and the lower end thereof is provided with the oil inlet valve; the lower end of the long plunger is positioned inside the lengthened inner cylinder; the oil inlet valve is communicated with the flow channel body; the lower end of the pump cylinder is provided with the lower joint that is communicated with a sand setting tube; and an anti-sand pump is arranged in the sand setting tube which is communicated with the sand filtration tube through the release packer. The utility model has the following effects of being capable of effectively preventing sand grains from entering a sealing clearance between the pump cylinder and the plunger, thus being characterized by the prevention from being blocked, buried and abraded by sand, resistance to corrosion, long service life and the like, and being capable of greatly prolonging exemption period of the oil well.
Description
One, technical field:
The utility model relates to the oil well pump of a kind of oil field construction operation, specifically is a kind of long-plunger formula sand-proof oil-well pump.
Two, background technique:
At present, the oil-containing geologic structure in the many oil fields of China is more loose, and it is more to contain sand in the well liquid, adopts the conventional pumps oil pumping that sand card, sand milling and corrosion often take place, and makes the oil well pump premature failure, causes oil well to stop production, and operation is frequent, and the cost of production of crude oil improves.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, provides a kind of principle simple, the long-plunger formula sand-proof oil-well pump that sand controlling result is good.
Its technological scheme is: the utility model comprises long-plunger, short pump barrel, runner body, lower contact, oiling valve, outlet valve, back-off packer and sand screen, the long-plunger upper end is provided with outlet valve, the long-plunger lower end is provided with down outlet valve, lengthening inner core upper end is provided with short pump barrel, lengthening inner core lower end is provided with oiling valve, the lower end of long-plunger is positioned at lengthening inner core inside, oiling valve is communicated with the runner body, the pump barrel lower end is provided with lower contact, lower contact is communicated with sand sediment pipe, sand sediment pipe inside is provided with sand-control pump, and sand sediment pipe is communicated with sand screen by back-off packer.
Long-plunger formula sand-proof oil-well pump adopts sand setting, side direction oil-feed structure under long-plunger, short pump barrel and the pump.The working principle of its sand control card is exactly the acting in conjunction by sand screen and sand sediment pipe, and the prevention sand grains enters the seal clearance between plunger and the pump barrel, thereby has stopped the sand card, has alleviated the wearing and tearing of pump barrel and plunger, and it is destroyed that surface strengthen layer is difficult for.When bumping off a well, the sand grains of sinking sinks to tail pipe under the pump along the sand setting annular space, can not resemble to build up on pump the conventional pumps, has avoided sand to bury sucker rod.
Effect of the present utility model is: can prevent effectively that sand grains from entering the seal clearance between pump barrel and the plunger, characteristics such as therefore have that sand control card, sand control bury, anti-sand milling, corrosion protection, life-span are long can prolong oil well repair free period widely.
Four, description of drawings:
Accompanying drawing is a structure sectional view of the present utility model.
Five, embodiment:
With reference to accompanying drawing, the utility model comprises long-plunger 8, short pump barrel 2, runner body 6, lower contact 7, oiling valve 5, last outlet valve 1, following outlet valve 4, back-off packer 9 and sand screen 10, long-plunger 8 upper ends are provided with outlet valve 1, long-plunger 8 lower ends are provided with down outlet valve 4, lengthening inner core 3 upper ends are provided with short pump barrel 2, lengthening inner core 3 lower ends are provided with oiling valve 5, the lower end of long-plunger 8 is positioned at lengthening inner core 3 inside, oiling valve 5 is communicated with runner body 6, pump barrel 12 lower ends are provided with lower contact 7, lower contact 7 is communicated with sand sediment pipe 13, and sand sediment pipe 13 inside are provided with sand-control pump 11, and sand sediment pipe 13 is communicated with sand screen 10 by back-off packer 9.
