Abstract
A stainless steel plate net type high permeability sand filter tube mainly solves the problem that the prior stainless steel plate net type anti-sand pipes are poor in permeability and easy to be blocked up, which is characterized in that a support tendon (2) is fixed between the adjacent meshes of a sieve tube (3) and then not covered by a stainless steel plate net (4). The utility model is characterized in good permeability, difficulty to be blocked up and long life-span.
Description
Technical field:
The utility model relates to the used downhole tool class in oil recovery field, oil field, especially the high infiltration of stainless steel plate mesh formula sand screen.
Background technology:
In the oil recovery process of oil field, in order to prevent that silt from entering in the flow string, usually with under the anti-sandpipe of stainless steel plate mesh formula in oil reservoir, the anti-sandpipe of stainless steel plate mesh formula is made up of the pillar of screen casing, stainless steel plate mesh and band bar hole, during oil well pump work, stainless steel plate mesh tightly is attached on the screen casing under suction function, and making between stainless steel plate mesh and the screen casing does not have hole, cause screen casing to stop up easily, thereby influenced the permeability of oil.
The utility model content:
In order to overcome anti-poor, the susceptible to plugging deficiency of sandpipe permeance property of existing stainless steel plate mesh formula, the utility model provides a kind of stainless steel plate mesh formula height infiltration sand screen, and the high infiltration of this stainless steel plate mesh formula sand screen has the advantages that permeance property is good, be difficult for obstruction and long service life.
The technical solution of the utility model is: the high infiltration of this stainless steel plate mesh formula sand screen comprises pipe collar, screen casing, stainless steel plate mesh and pillar, is being covered mutually by stainless steel plate mesh behind the fixed support muscle between the screen casing adjoining cells.
The utlity model has following beneficial effect: owing to covered mutually by stainless steel plate mesh behind the fixed support muscle between the screen casing adjoining cells, make between screen casing and the stainless steel plate mesh and form cavity, increased the utilization rate and the rigidity of stainless steel plate mesh, permeance property is good, difficult to be stopped up and long service life.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is A-A sectional drawings of the present utility model.
1-pipe collar among the figure, 2-brace rod, 3-screen casing, 4-stainless steel plate mesh, 5-pillar.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., the high infiltration of this stainless steel plate mesh formula sand screen comprises pipe collar 1, screen casing 3, stainless steel plate mesh 4 and pillar 5, be welded with brace rod 2 on the screen casing 3 between mesh, stainless steel plate mesh 4 covers on the top of brace rod 2 mutually, make between screen casing 3 and the stainless steel plate mesh 4 and form cavity, thereby increased the utilization rate and the rigidity of stainless steel plate mesh 4, be difficult for making screen casing 3 to stop up, improved the permeability of oil and the application life of stainless steel plate mesh 4.
During actual the use, stainless steel plate mesh 4 and pillar 5 usefulness pipe collars 1 are stuck on the screen casing 3 that has brace rod 2, one terminates on the flow string, and the other end inserts in the oil reservoir.
Claims (1)
1, the high infiltration of a kind of stainless steel plate mesh formula sand screen comprises pipe collar (1), screen casing (3), stainless steel plate mesh (4) and pillar (5), it is characterized in that: fixed support muscle (2) back is covered mutually by stainless steel plate mesh (4) between screen casing (3) adjoining cells.
