The vibration spring is conical, the upper part is small, the lower part is large, and the bottom end of the vibration spring is fixed on the lower joint.
And the upper end of the outer pipe is provided with a liquid inlet hole.
The utility model discloses an application method: 1. The device is directly connected to the lower part of an oil well pump, so that an oil inlet hole is immersed in well fluid, and reasonable submergence is kept; 2. according to the underground sand-containing condition, connecting a proper sand setting pipe, wherein the longest sand setting pipe is not more than 200 m; 3. a release may be attached to the lower portion of the liner to release the separated sand downhole and to allow the sand to be deposited at a height for pumping or flushing to the surface.
When the sucker rod pump performs upstroke suction, the traveling valve is closed, the fixed valve is opened, well liquid flows into the pipe from the upper part of the outer cylinder through the liquid inlet hole, flows into the working cavity of the lower conical sand prevention filter screen through a channel between the upper end of the conical sand prevention filter screen and the inner cavity of the outer pipe, and enters the inner pipe through the filtering of the conical sand prevention filter screen, sand grains with the grain size larger than 180 meshes are blocked by the conical sand prevention filter screen to the outside through the conical sand prevention filter screen, the upper end surface of the conical sand prevention filter screen and the inner cavity of the outer pipe are provided with throttling surfaces, liquid flowing in from the liquid inlet hole during upstroke suction of the sucker rod pump generates throttling between the upper end surface of the conical sand prevention filter screen and the throttling surfaces of the inner cavity of the outer pipe, the flowing liquid applies downward thrust to the upper end surface of the conical sand prevention filter screen to push the conical sand prevention filter pipe and the.
When the rod pump moves downwards, the moving valve is opened, the fixed valve is closed, no well liquid flows into the pipe from the liquid inlet hole at the upper part of the outer pipe, no external force acts on the upper end surface of the conical sand prevention filter screen, the elastic deformation generated by the compression of the conical vibration spring during the upper stroke of the rod pump is recovered, the upward elastic force accumulated by the conical vibration spring is released, and the inner pipe and the conical sand prevention filter screen are enabled to integrally generate upward displacement.
Because the corrugated pipe is soft and has contractibility, the requirement that the inner pipe and the conical sand control filter screen integrally move up and down in the pumping process of the sucker-rod pump is met.
The centralizing vibration spring keeps the inner pipe and the conical sand control filter screen to integrally move up and down without deviating from the central line, and the corrugated pipe is not deviated from the inner pipe and the conical sand control filter screen and is not abraded with the inner pipe. And simultaneously, the inner pipe and the conical sand control filter screen generate vibration.
The filtered well liquid continues to the upper intake pump barrel, and the conical vibration spring is compressed and automatically reset when the sucker rod pump pumps the upper stroke and the lower stroke, so that the inner pipe and the conical sand control filter screen generate vertical displacement and vibration, sand grains outside the conical sand control filter screen are shaken off, and the filtering function of the filter screen is ensured.
