Description
Technical field
This utility model relates to a kind of sand-proof pipe, particularly to a kind of sintered meshwork precision sand-screen.
Background technology
Current each elephant is wide variety of is screen mesh type sand-screen, the filter course of screen mesh type sand-screen is made up of the most independent layer 2-3 drainage screen and flow-guiding screen, drainage screen and flow-guiding screen are overlapped mutually, and filter course is followed successively by drainage screen-flow-guiding screen-drainage screen-flow-guiding screen from outside to inside.Its defect existed is: if after 1 reservoir sand enters outermost layer drainage screen and intercepted by second layer drainage screen, reservoir sand will remain in the flow-guiding screen grid between two-layer drainage screen, constantly will result in blocking after accumulation.Even if backwash also is difficult to go out reservoir sand；2, separate due to each layer, becoming, filter course thickness is excessive, thus causes screen casing maximum outside diameter relatively large, is unfavorable for going into the well or easily blocking；3, independent filter course screen cloth bearing capacity is poor, easily causes screen cloth tear when High Pressure Difference, gas injection or backwash；4, establishment type filter course screen cloth is easily causing organizine or latitude skew when high pressure washes away, forms bigger mesh, screen casing filtration inefficiencies.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, a kind of sintered meshwork precision sand-screen is provided, there is back-washable property, multi-layer sintering net is after High Temperature High Pressure sinters, thickness is substantially reduced, make screen casing entire outer diameter less than screen mesh type sand screen, be conducive to going into the well, reduce accident rate.
Its technical scheme is: include filter element, perforated base pipe, first weld seam, second weld seam, 3rd weld seam, 4th weld seam, filter element includes sintered meshwork filter course, outer jointing jacket, interior end ring, outer end ring, it is provided with interior end ring in the bottom of sintered meshwork filter course, it is provided with outer end ring in the bottom of interior end ring, the first weld seam it is provided with between sintered meshwork filter course and interior end ring, sintered meshwork filter course is welded together by the first weld seam with interior end ring, it is provided with outer jointing jacket in the outside of sintered meshwork filter course, the second weld seam it is provided with between outer jointing jacket and interior end ring, outer jointing jacket is welded together by the second weld seam with interior end ring, the 3rd weld seam it is provided with between interior end ring and outer end ring, interior end ring is welded together by the 3rd weld seam with outer end ring.
Above-mentioned filter element is sleeved on perforated base pipe, and filter element is welded on perforated base pipe by the 4th weld seam, and described sintered meshwork filter course is made up of the mesh grid of different meshes, and screen diameter becomes big, described outer jointing jacket successively and is provided with hole.
The beneficial effects of the utility model are: this utility model has back-washable property, owing to the screen diameter of sintered meshwork filter course becomes big successively, as long as so the reservoir sand through sintered meshwork filter course will all be carried away by the flow, do not result in deposition and hinder backwash, the advantage that this utility model has continued screen mesh type sand-screen, compensate for again the deficiency of screen mesh type sand-screen simultaneously, perforated protective jacket can effectively reduce screen casing complement outside diameter, multi-layer sintering net is after High Temperature High Pressure sinters, thickness is substantially reduced, make screen casing entire outer diameter less than screen mesh type sand screen, be conducive to going into the well, reduce accident rate, thus reduce lock of tool drilling of going into the well, this utility model can extend the use cycle of screen casing effectively, increase economic efficiency；Of a relatively high area of passage, can effective guarantee production capacity.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model；
In upper figure: sintered meshwork filter course 1, outer jointing jacket 2, perforated base pipe 3, interior end ring 4, outer end ring the 5, first weld seam the 6, second weld seam the 7, the 3rd weld seam the 8, the 4th weld seam 9.
Detailed description of the invention
In conjunction with accompanying drawing 1, the utility model will be further described:
This utility model includes filter element, perforated base pipe 3, first weld seam 6, second weld seam 7, 3rd weld seam 8, 4th weld seam 9, filter element includes sintered meshwork filter course 1, outer jointing jacket 2, interior end ring 4, outer end ring 5, interior end ring 4 it is provided with in the bottom of sintered meshwork filter course 1, it is provided with outer end ring 5 in the bottom of interior end ring 4, the first weld seam 6 it is provided with between sintered meshwork filter course 1 and interior end ring 4, sintered meshwork filter course 1 is welded together by the first weld seam 6 with interior end ring 4, it is provided with outer jointing jacket 2 in the outside of sintered meshwork filter course 1, the second weld seam 7 it is provided with between outer jointing jacket 2 and interior end ring 4, outer jointing jacket 2 is welded together by the second weld seam 7 with interior end ring 4, it is provided with the 3rd weld seam 8 between interior end ring 4 and outer end ring 5, interior end ring 4 is welded together by the 3rd weld seam 8 with outer end ring 5.
