Description
Technical field: this utility model relates to oil-well pump sand-proof technology, especially a kind of with oil well pump suction filter screen vibrations
Sand preventing tool.
Background technology: at present, the filter screen sand preventing tool used on oil well, absorption is not had certainly at the fine silt of drainage screen
Clean ability, through absorption for a long time, on fine silt absorption filter screen slowly, forms sand cake, progressively blocks feed pathway, make to lead to
Road diminishes, eventually cause oil inlet passage large area be adsorbed fine silt formed sand cake block, the mistake of little area oil inlet passage
Filter screen is badly damaged under oil well pump swabbing action, loses the filtration of filter screen, and fine silt is entered by the drainage screen damaged
Enter oil pump sleeve, cause holddown, cause operation just can resume production, shorten the effect of sand control.
Summary of the invention: the purpose of this utility model is to provide the one with sand control effect with oil well pump suction filter screen vibrations
Sand preventing tool.It solve a difficult problem for current technology, the purpose of this utility model be achieved in that it be by top connection,
Outer tube, inner tube, spring fastening, filter screen, spring carrier arm, spring, filter screen band, lower contact are formed by connecting, in the upper end of outer tube even
Then top connection, is connected to lower contact in the lower end of outer tube；Inner tube is had in the centre of outer tube；Upper and lower two spring fastenings are solid respectively
Periphery due to inner tube；Being respectively arranged with spring carrier arm on upper and lower two spring fastenings, the two ends of spring are hung in two ends
Spring carrier arm on；Filter screen is positioned at outer spring end, and filter screen is fixed at the both sides filter screen band of spring carrier arm.
Described outer tube, its upper and lower side is respectively arranged with inlet opening.
Described inner tube, its upper and lower side is respectively arranged with inlet opening；The liquid outlet of inner tube communicates with the inlet opening of oil well pump.
Described spring fastening, its top is evenly equipped with lead channel, screwed hole, circumferential groove, and fixes filter screen on circumferential groove
Tubular two ends.
Described filter screen, it is cylindric, and its two ends are fixed on the circumferential groove of spring fastening；The aperture of filter screen is 150-
200 mesh.
Described spring, it is stretching spring, can be deformed with the pressure of filter screen.
Application process of the present utility model is: this device in the position of sucker rod pumping tubing string, tubing string group from bottom to top
It is combined into: plug (release)+tail pipe+this device+connect pump pipe nipple+oil well pump+flow string；Liquid is from outer tube inlet opening enters
Tube cavity, through filter screen filtration, particle diameter is blocked in outside drainage screen more than the sand grains of filter screen filter opening, and the liquid of filtration is through inner tube
Inlet opening enters the inner chamber of inner tube, and inner tube is connected with the feed pathway of oil well pump by top connection, is made by the suction of oil well pump
With, filtered liquid is given rise to ground；When flowing through sand control filter screen during oil well pump suction, owing to filter screen is the closeest, fluid is to filter
Net surface produces pressure, and filter screen is due to for flexible article, thus spring is produced pressure, and spring bending is attached to outer wall of inner tube,
When oil well pump stops suction, time the most descending, spring relies on elastic return in situ；So that spring produces vibrations, camber of spring is multiple
Position makes filter screen deform outwardly, thus forms a kind of slight vibrations, makes the fine silt of filtration not be attracted on drainage screen, at weight
It is deposited in tail pipe by sand setting passage under power effect.
Meaning of the present utility model is: one there is provided a kind of filter net device with vibration function and method, so that
Feed pathway is not easily blocked, and oil well pump is difficult to holddown；Two are the reduction of the maintenance oil pumping pump time, improve work efficiency；Three
It is reduction of maintenance cost.
Accompanying drawing illustrates: Fig. 1 is a kind of structural representation of sand preventing tool with oil well pump suction filter screen vibrations, in figure 1, on
Joint 2, outer tube 3, inner tube 4, spring fastening 5, filter screen 6, spring carrier arm 7, spring 8, filter screen band 9, lower contact
Detailed description of the invention: embodiment 1, this utility model are by top connection 1, outer tube 2, inner tube 3, spring fastening 4, filter screen
5, spring carrier arm 6, spring 7, filter screen band 8, lower contact 9 are formed by connecting, and are connected to top connection 1 in the upper end of outer tube 2, at outer tube
The lower end of 2 is connected to lower contact 9；Inner tube 3 is had in the centre of outer tube 2；Upper and lower two spring fastenings 4 are individually fixed in inner tube 3
Periphery；Being respectively arranged with spring carrier arm 6 on upper and lower two spring fastenings 4, the two ends of spring 7 are hung in the spring at two ends and hang
On hook 6；Filter screen 5 is positioned at spring 7 outer end, and filter screen 5 is fixed with filter screen band 8 in the both sides of spring carrier arm 6.
Embodiment 2, described outer tube 2, its upper and lower side is respectively arranged with inlet opening.
Embodiment 3, described inner tube 3, its upper and lower side is respectively arranged with inlet opening；The liquid outlet of inner tube 3 and oil well pump
Inlet opening communicates.
Embodiment 4, described spring fastening 4, its top is evenly equipped with lead channel, screwed hole, circumferential groove, and on circumferential groove
It is fixed with the two ends of filter screen 5.
