Abstract
The utility model discloses a rotational-flow high-efficient sand setting device, which is formed by an upper connector, a core pipe with a hole, a sand setting pipe and a rotational flow body. The core pipe with the hole is connected onto the lower portion of the upper connector, and the sand setting pipe is connected onto the lower portion of the upper connector and sleeved outside the core pipe with the hole. The rotational flow body is connected onto the lower portion of the sand setting pipe, a liquid suction port is sleeved inside the rotational flow body, a liquid inlet is arranged on the lateral portion of the rotational flow body, the liquid inlet and the axial direction form an included angle ranging from 5 degrees to 40 degrees, and the liquid inlet is tangent with an inner round face of the rotational flow body. A sand guiding inclined face is arranged on the inner wall of the bottom of the sand setting pipe. Under the double-acting of rotational flow sand removing and gravity sand setting of well liquid, sand removing efficiency is greatly improved, most sand is removed, and very little fine powder sand is pumped onto the ground, thereby greatly reducing the effects of the sand to service life of an oil pump and a pump valve.
Description
Technical field
The utility model relates to a kind of oil field oil recovery kit, the efficient sand-settling device of particularly a kind of eddy flow.
Background technology
At present, oil well is used for the sand anchor of sand setting, its pod apertures with axially meet at right angles and not tangent with the rotary fluid inner headed face, the liquid in rotation speed that causes flowing into is low, the sand in the liquid is not easy to be sunken to the dead band.
Summary of the invention
The purpose of the utility model provides the efficient sand-settling device of a kind of eddy flow, and the efficient sand-settling device of this eddy flow utilizes eddy flow centrifugal force desanding mode to combine with the gravitational settling mode, and desanding effect is even more ideal.
The utility model is made up of top connection, core pipe with holes, sand sediment pipe, rotary fluid, and core pipe with holes is connected in the top connection bottom, and sand sediment pipe is connected in the top connection bottom and is set in core pipe with holes outside; Rotary fluid is connected the sand sediment pipe bottom and liquid sucting port is sleeved on inside, and the rotary fluid sidepiece offers inlet opening, inlet opening with axially become 5-40 degree angle and tangent with the rotary fluid inner headed face, the bottom interior wall of sand sediment pipe has the sand of leading inclined-plane.
Described inlet opening is two groups, and every group has three inlet openings.
The course of work of the utility model and principle:
The side direction of well liquid from rotary fluid tiltedly descended the process of inlet opening entering; Side direction tiltedly down and with the effect of the tangent inlet opening of rotary fluid endoporus under; The flow that formation is rotated at a high speed along the rotary fluid inner surface; Granular sand and impurity sink along rotary fluid inner surface rotation under action of centrifugal force, and purer well liquid is placed in the middle and be sucked on the liquid sucting port and be advanced in the sand sediment pipe.When oil pump plunger piston finishes a upstroke; The well liquid that is sucked by liquid sucting port does not get into core pipe with holes, and in oil pump plunger piston down stroke process, the well liquid that does not get into core pipe with holes carries out gravitational settling one time in this time; Under the effect of leading the sand inclined-plane; Sink in the dead band below the liquid sucting port, when oil pump plunger piston is pumped once more, sand and the impurity that gets into the dead band will no longer be taken out and sunk in the tail pipe that sediment by rotational flow device bottom connected.
The beneficial effect of the utility model is: well liquid is under the double acting of eddy flow desanding and gravitational sand settling; Improved desanding efficiency greatly; Overwhelming majority sands are removed, few parts of fine flour sand is sucked into ground, have reduced the influence of sand to the life-span of oil well pump and pump valve greatly; Well liquid is produced after desanding, reduces the wearing and tearing of oil well pump and pump valve, reduces the probability that pump is blocked by sand, improves pump efficiency, prolongs oil well repair free period.

The specific embodiment
See also illustrated in figures 1 and 2ly, present embodiment is made up of top connection 1, core pipe with holes 2, sand sediment pipe 3, rotary fluid 4, and core pipe 2 with holes is connected in top connection 1 bottom, and sand sediment pipe 3 is connected in top connection 1 bottom and is set in core pipe with holes 2 outsides; Rotary fluid 4 is connected sand sediment pipe 3 bottoms and liquid sucting port 32 is sleeved on inside, and rotary fluid 4 sidepieces offer inlet opening 41, inlet opening 41 with axially become 5-40 degree angle and tangent with rotary fluid 4 inner headed faces, the bottom interior wall of sand sediment pipe 3 has the sand of leading inclined-plane 31.
Described inlet opening 41 is two groups, and every group has three inlet openings 41.
The course of work of present embodiment and principle:
The side direction of well liquid from rotary fluid 4 tiltedly descended the inlet opening 41 entering processes; Side direction tiltedly down and with the effect of the tangent inlet opening 41 of rotary fluid 4 endoporus under; The flow that formation is rotated at a high speed along rotary fluid 4 inner surfaces; Granular sand and impurity sink along rotary fluid 4 inner surfaces rotations under action of centrifugal force, and purer well liquid is placed in the middle and be sucked on the liquid sucting port 32 and be advanced in the sand sediment pipe 3.When oil pump plunger piston finishes a upstroke; The well liquid that is sucked by liquid sucting port 32 does not get into core pipe 2 with holes, and in oil pump plunger piston down stroke process, the well liquid that does not get into core pipe 2 with holes carries out gravitational settling one time in this time; Under the effect of leading sand inclined-plane 31; Sink in the dead band of liquid sucting port below 32, when oil pump plunger piston is pumped once more, sand and the impurity that gets into the dead band will no longer be taken out and sunk in the tail pipe that sediment by rotational flow device bottom connected.
