Abstract
The utility model discloses a kind of down-hole associated gas atmospheric buffer device, comprise swirl vane axle, swirl vane axle is provided with some swirl vanes, swirl vane is semi-circular shape, diameter of a circle is 2-3m, and swirl vane axle outer setting has sleeve, and swirl vane is fixed on swirl vane axle in a welding manner, swirl vane is sequentially arranged on swirl vane axle with the helical form at 60 °, interval, and the distance between adjacent two swirl vanes is 15-20cm.This device does not rely on any power, swirl vane is only relied on to change the direction of gas-liquid flow motion, increase the frictional resistance between gas-liquid flow and sleeve, effectively increase the pressure loss that gas-liquid flow arrives pump barrel, thus reach reduction gas to the object of the impact of standing valve.In addition, the direction that effectively can change gas-liquid flow motion when meeting with gas-liquid flow and impacting arranged evenly of swirl vane, reduces the speed of gas-liquid flow motion, and protection standing valve base, prevents base from stinging and leak.
Description
Technical field
The utility model belongs to oil field equipment technology technical field, is specifically related to a kind of down-hole associated gas atmospheric buffer device.
Background technology
Associated gas be under earth's surface in pore formation based on the hydrocarbon gas of low molecule saturated hydrocarbons and a small amount of non-hydrocarbon gases composition flammable mixture, it is the gaseous form of oil, associated gas great majority are based on first hydrocarbon, include ethane, propane etc., also include the gaseous states such as a small amount of ammonia, sulfur dioxide, hydrogen sulfide.At present, there is a large amount of associated gases in some oil wells, and cause downhole gas pressure large, larger gas-liquid pressure can impact oil well pump standing valve, the standing valve when travelling valve is descending cannot be closed, directly cause oil well not go up liquid.
Utility model content
The purpose of this utility model is to provide a kind of down-hole associated gas atmospheric buffer device, reduces the impact of down-hole associated gas to standing valve, solves the inc problem of standing valve.
The technical scheme that the utility model adopts is: a kind of down-hole associated gas atmospheric buffer device, comprises swirl vane axle, swirl vane axle is provided with some swirl vanes.
Feature of the present utility model is also:
Swirl vane is semi-circular shape, and diameter of a circle is 2-3m.
Swirl vane axle outer setting has sleeve.
Swirl vane is fixed on swirl vane axle in a welding manner.
Swirl vane is sequentially arranged on swirl vane axle with the helical form at 60 °, interval.
Distance between adjacent two swirl vanes is 15-20cm.
The beneficial effects of the utility model are: a kind of down-hole associated gas atmospheric buffer device, do not rely on any power, swirl vane is only relied on to change the direction of gas-liquid flow motion, increase the frictional resistance between gas-liquid flow and sleeve, effective increase gas-liquid flow arrives the pressure loss of pump barrel, thus reaches reduction gas to the object of the impact of standing valve.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of down-hole of the utility model associated gas atmospheric buffer device.
In figure, 1. sleeve, 2. swirl vane axle, 3. swirl vane.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of down-hole associated gas atmospheric buffer device as shown in Figure 1, comprise swirl vane axle 2, swirl vane axle 2 is provided with some swirl vanes 3, swirl vane 2 is semi-circular shape, diameter of a circle is 2-3m, and swirl vane axle 2 outer setting has sleeve 1, and swirl vane 3 is fixed on swirl vane axle 2 in a welding manner, swirl vane 3 is sequentially arranged on swirl vane axle 2 with the helical form at 60 °, interval, and the distance between adjacent two swirl vanes 3 is 15-20cm.
During use, what swirl vane axle 2 utilized is waste and old sucker rod, and swirl vane 3 is welded on sucker rod, and what swirl vane 3 utilized is waste and old iron plate, and whole device is arranged on oil-well pump bottom, and the density of swirl vane 3 can regulate according to gas pressure size.
A kind of down-hole of the utility model associated gas atmospheric buffer device, do not rely on any power, swirl vane is only relied on to change the direction of gas-liquid flow motion, increase the frictional resistance between gas-liquid flow and sleeve, effective increase gas-liquid flow arrives the pressure loss of pump barrel, thus reaches reduction gas to the object of the impact of standing valve.In addition, the direction that effectively can change gas-liquid flow motion when meeting with gas-liquid flow and impacting arranged evenly of swirl vane, reduces the speed of gas-liquid flow motion, and protection standing valve base, prevents base from stinging and leak.
