Abstract
The utility model relates to a sand anchor for filtering net of tubelike stainless steel-plate, which has two layers of structure, namely round hole inner pipe outer sleeve stainless steel plate filter screen or round hole outer pipe internal lining stainless steel plate filter screen. The utility model has advantages that the filter screen hole shape and hole distance are fastened evenly, without deformation after bearing, the sand anchor filters the oil smoothly, effectively remove sand and impurity to protect an oil pump and reduce the sand anchor weight. The service life is more than 6-8 times of traditional sand anchors.
Description
The utility model is the dividing an application of patent application of (number of patent application is 00212029.1, name be called stainless steel board filter screen) that belong to that applying date 2000.05.30 proposes.
The utility model relates to a kind of tubular stainless steel board filter screen sand anchor that is applied on the oil field drilling operation sand anchor.
At present; normally used screen pack on the sand anchor that oil field drilling operation is used; be to work out with metal or nonmetal monofilament; filter mesh deforms under the effect of pressure and loses shape, and mesh is inhomogeneous, poor filtration effect; mesh deforms under the effect of pressure and loses shape; and, comprise that from structure interior pipe, spy purchase multiple filtration and protection ways such as sand material, screen pack, outer tube, thereby increased sand anchor weight.
The purpose of this utility model provides a kind of have fixing uniform hole shape, pitch-row tubular stainless steel board filter screen sand anchor simple in structure.
The utility model is achieved in that
Tubular stainless steel board filter screen sand anchor has double-layer structure, promptly is drilled with the interior pipe overcoat tubular stainless steel board filter screen of circular hole or is drilled with the outer tube liner tubular stainless steel board filter screen of circular hole, and a headband of pipe has screw thread, and the other end is connected to pipe collar.
Above-mentioned tubular stainless steel board filter screen sand anchor, its tubular stainless steel board filter screen are evenly perforates on a corrosion resistant plate, are rolled into drum again, the thickness of corrosion resistant plate is 0.2-0.4mm, hole shape has strip or circle, and the aperture is 0.08-0.4mm, pitch-row 1.0-2.25mm.
Benefit of the present utility model is:
Tubular stainless steel board filter screen sand anchor is perforate uniformly on the corrosion resistant plate basis; so the hole shape of screen pack, pitch-row are fixed evenly; indeformable after the pressure-bearing; keep the shape; sand anchor oil strain smoothness can effectively be removed the sand and the impurity that contain in the oil, plays the effect of protection oil pump; reduced the weight of sand anchor, be traditional sand anchor application life 6-8 doubly more than.
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 stainless steel board filter screen schematic diagram
Fig. 2 tubular stainless steel board filter screen schematic diagram
Fig. 3 tubular stainless steel board filter screen sand anchor schematic diagram
Fig. 1 has represented a kind of stainless steel board filter screen, and corrosion resistant plate 1 thickness is 0.3mm, hole shape circle 2, and aperture 0.2mm, pitch-row 1.5mm, it is evenly fixing to have a hole shape, pitch-row, indeformable under the pressurized, keeps the shape advantages such as good filtration effect.
Fig. 2 has represented a kind of tubular stainless steel board filter screen, and corrosion resistant plate 1 thickness is 0.3mm, hole shape circle 2, and aperture 0.2mm, pitch-row 1.5mm is welded into the pipe that diameter is φ 73mm with spot welder.
Fig. 3 has represented a kind of tubular stainless steel board filter screen sand anchor; double-layer structure is arranged; promptly be drilled with the interior pipe 3 overcoat tubular stainless steel board filter screens 4 of circular hole; changed and adopted establishment net sand anchor to need interior pipe, spy to purchase the multiple filtration and the protection way of sand material, screen pack, outer tube; have in light weight; good filtration effect, advantages such as long service life.
