Abstract
The utility model discloses an oil well ground sand filter. The oil well ground sand filter is a sand filter for pipeline crude oil transportation, and can be used for reducing the leakage accident probability of crude oil in the crude oil transportation pipeline, so that the service life of the pipeline is prolonged. For the appearance of the oil well ground sand filter, the upper part of the oil well ground sand filter is ellipsoidal, the middle part of the oil well ground sand filter is cylindrical, the lower part of the oil well ground sand filter is conical, and crude oil tangentially enters a body (1) from an inlet (2); and due to the centrifuge principle, oil-gas-water output by an oil well is discharged from an outlet (3) through an upper channel, filtered sand is accumulated at the bottom of the body, a sand discharging port (4) is opened periodically to discharge the sand.
Description
One, technical field
The utility model relates to the filter sand equipment of oil well oil transportation pipeline, specifically a kind of oil well ground sand filter.
Two, background technology
The crude oil of underground extraction will be transported to oil gathering station by oil pipeline, in the Crude Oil Transportation process, because contain sand grains in the crude oil, sand grains sinks to duct bottom at Action of Gravity Field, crude oil drives these sand grains motions when flowing in pipeline, duct bottom forms sand cutting, cause easily oil pipeline frequently to bore a hole, cause crude oil leakage, pollute on the one hand environment, bring loss to national wealth on the other hand, the serious oil pipeline that causes is scrapped.
Three, summary of the invention
According to above-mentioned problems of the prior art, the utility model provides a kind of oil well ground sand filter, and it can overcome above-mentioned problems of the prior art effectively.
A kind of oil well ground sand filter that is installed on the oil pipeline described in the utility model comprises by top it being that the ellipsoid centre is that the cylinder bottom is body and import, outlet and the sand removing hole that cone forms.
Wherein, the import of described oil well ground sand filter is installed in the side and body is tangent.
The utility model has the following advantages:
1, the starting point of pipeline just can effectively be filtered the sand grains in the crude oil, has avoided the damage of sand grains to oil pipeline, has prolonged the life-span that pipeline uses, and has reduced the generation of oil spill disaster.
2, reduced the environmental pollution that causes owing to crude oil leakage, and the crude oil loss.
Four, description of drawings
Accompanying drawing is structural representation of the present utility model
Five, the specific embodiment
Consult accompanying drawing, a kind of oil well ground sand filter, comprise the oil gas water inlet 2 of installing in body 1 and side thereof, the oil gas water out 3 that install at the top, the sand grains that filters out in the crude oil is regularly discharged from the sand removing hole 4 of bottom, this oil well ground sand filter is installed on the petroleum pipeline of well mouth of oil well, filters the sand grains in the crude oil.
Claims (2)
1. oil well ground sand filter that is installed on the oil pipeline is characterized in that: be to be that the cylinder bottom is the body (1), the import (2) that form of cone, exports (3), sand removing hole (4) in the middle of the ellipsoid by top.
2. oil well ground sand filter according to claim 1, it is characterized in that: described import (2) is installed in the side and body (1) is tangent.
