Abstract
The utility model relates to an oil extraction sand filtering device used for various geological structures of a thermal extracting well, a high coagulated oil well, a polymer well, a thin oil well, etc. The device is composed of a central tube, a stainless steel plate net and an outer tube; the stainless steel plate net is arranged at the outer part of the central tube, the eyed structure of the stainless steel plate net is discontinuously arranged in a curve shape, and the outer part of the curve-shaped stainless steel plate net is provided with the outer tube; the stainless steel plate net of the stainless steel plate net anti-sand tube has the best effect when the eyed structure thereof is in the swallow wing shape. The utility model has the advantages of high sand filtering precision, extensive anti-sand range, good permeating rate, low oil extracting cost, high oil yield, corrosion prevention, and long service life.
Description
Technical field
The utility model relates to the oil recovery filter sand device of various geologic structures such as being used for thermal production well, high-solidifiability oil well, polymer well, thin oil well.
Background technology
In the prior art, the filter sand device that oil well uses is made up of interior pipe, stainless steel plate mesh, outer tube, and the stainless steel plate mesh of employing is " one " font structure, and the problem of its existence is: the filter sand area is little; Rigidity is big, has grown easy fracture service time.
Summary of the invention
The purpose of this utility model provides the swallow-wing shape stainless steel plate mesh sand control tube that a kind of filter sand area is big, flexibility is good, tar productivity is high.
Swallow-wing shape stainless steel plate mesh sand control tube is characterized in that: this device is made up of central tube, stainless steel plate mesh, outer tube, and stainless steel plate mesh is located at the central tube outside, and its eyed structure is that shaped form is interrupted arrangement, is provided with outer tube in the outside of shaped form stainless steel plate mesh.
The stainless steel plate mesh of stainless steel plate mesh sand control tube recited above, its eyed structure are swallow-wing shape effect structure the best.
The utility model has the advantages that filter sand precision height, the sand control scope is wide, and permeability is good, reduces cost for oil production, improves oil yield, corrosion-resistant, long service life.Because stainless steel plate mesh adopts the shaped form structure, " one " font stainless steel plate mesh filter sand area is big for the filter sand area, and flexible good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the expanded view of swallow-wing shape stainless steel plate mesh.
The specific embodiment
See Fig. 1, swallow-wing shape stainless steel plate mesh sand control tube is made up of central tube 1, stainless steel plate mesh 2, outer tube 3, and stainless steel plate mesh 2 is located at central tube 1 outside, and its mesh 5 structures are that shaped form is interrupted arrangement, are provided with outer tube 3 in the outside of shaped form stainless steel plate mesh 2.
The stainless steel plate mesh of stainless steel plate mesh sand control tube recited above, its mesh 5 structures are swallow-wing shape effect structure the best (Fig. 2).
