Abstract
The utility model provides a separating sieve tube which is characterized in that the separating sieve tube is mainly composed of a basic tube (1), an inner supporting shunting layer (2), micropore net cloth (3), an outer supporting shunting layer (4), a protective sleeve (5) and spacing supporting rings (6), wherein, the tube wall of the basic tube (1) is provided with flow holes (7), and the external side of the basic tube (1) from inside to outside is respectively provided with the inner supporting shunting layer (2), the micropore net cloth (3), the outer supporting shunting layer (4) and the protective sleeve (5); more than two spacing supporting rings (6) are welded in an annular space position between the protective sleeve (5) and the basic tube (1). Axial distances between every two adjacent spacing supporting rings (6) are almost the same. The protective sleeve (5) is also provided with flow holes (8) at positions almost corresponding to the positions of the flow holes (7) on the basic tube (1).
Description
The utility model relates to a kind of oil-sand or gas-sand separation device that oil field development is produced that be used for.
Employed separator has wrapping wire sieve, ceramic screen casing, metal wool screen casing etc. in producing at present, but these products aspects such as its sand controlling result, intensity are not ideal enough in actual applications, bring certain influence to the production in oil field.
The purpose of this utility model provides a kind of sand controlling result and the comparatively ideal Separating sieve tube of strength ratio.
To achieve these goals; technical solution of the present utility model is such: Separating sieve tube is mainly by parent tube; the interior shunting layer that supports; the micropore screen cloth; the outer shunting layer that supports; protective sleeve; spacing support ring constitutes; leave opening on the tube wall of parent tube; in being respectively equipped with from inside to outside, the parent tube outside supports shunting layer; the micropore screen cloth; the outer shunting layer that supports; protective sleeve; spacing support ring has more than two and is welded on annular space position between protective sleeve and the parent tube; the axial distance of adjacent two spacing support rings is roughly the same; also be provided with opening on the protective sleeve, the position of the opening on its position and the parent tube is corresponding substantially.
Because in the above-mentioned technical solution; in being provided with from inside to outside, the basic unit outside supports shunting layer; the micropore screen cloth; the outer shunting layer that supports; protective sleeve; spacing support ring then plays the effect that is connected and fixed each deck; in each deck; the micropore screen cloth plays the effect that separates sand block; the opening of parent tube and protective sleeve provides conductive channel; inside and outside support shunting layer then plays and makes fluid can shunt diffusion fully by before and after the network of micropores layer of cloth; thereby further increase the network of micropores cloth area that actual participation separates sand block, Separating sieve tube provided by the utility model in sum has compact conformation; good separating effect; the characteristics that intensity is higher.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the structural representation of the Separating sieve tube that provides of the present utility model.
Fig. 2 is the local structure for amplifying schematic diagram of Fig. 1.
Wherein: 1, parent tube; 2, interior support shunting layer; 3, micropore screen cloth; 4, support shunting layer outward; 5, protective sleeve; 6, spacing support ring; 7, opening; 8, opening.
As shown in the figure; Separating sieve tube is mainly by parent tube 1; the interior shunting layer 2 that supports; micropore screen cloth 3; the outer shunting layer 4 that supports; protective sleeve 5; spacing support ring 6 constitutes; leave opening 7 on the tube wall of parent tube 1; in being respectively equipped with from inside to outside, parent tube 1 outside supports shunting layer 2; micropore screen cloth 3; the outer shunting layer 4 that supports; protective sleeve 5; spacing support ring 6 have three and be welded on protective sleeve 5 and parent tube 1 between the annular space position; the axial distance of adjacent two spacing support rings 6 is identical; also be provided with opening 8 on the protective sleeve 5, the position of the opening 7 on its position and the parent tube 1 is corresponding substantially.In above-mentioned each layer, interior support shunting layer 2 supports shunting net for one deck, and micropore screen cloth 3 is the metal micro-holes screen cloth, supports the support shunting muscle of shunting layer 4 for spring-like outward.
When fluid is shunted; fluid passes micropore screen cloth 3 support shunting layer 4 and shunting diffusion earlier outside the opening 8 of protective sleeve 5 enters after; fluid sand grains in the process of passing micropore screen cloth 3 is blocked in micropore cloth 3 outsides, and fluid enters parent tube 1 endoporus through the opening 7 of interior support shunting layer 2 and parent tube 1 again.
Claims (3)
1; a kind of Separating sieve tube; it is characterized in that: Separating sieve tube is mainly by parent tube (1); the interior shunting layer (2) that supports; micropore screen cloth (3); the outer shunting layer (4) that supports; protective sleeve (5); spacing support ring (6) constitutes; leave opening (7) on the tube wall of parent tube (1); in being respectively equipped with from inside to outside, parent tube (1) outside supports shunting layer (2); micropore screen cloth (3); the outer shunting layer (4) that supports; protective sleeve (5); spacing support ring (6) have more than two and be welded on protective sleeve (5) and parent tube (1) between the annular space position; the axial distance of adjacent two spacing support rings (6) is roughly the same; also be provided with opening (8) on the protective sleeve (5), the position of the opening (7) on its position and the parent tube (1) is corresponding substantially.
2, Separating sieve tube according to claim 1 is characterized in that: interior support shunting layer (2) is for supporting shunting net, and micropore screen cloth (3) is the metal micro-holes screen cloth, supports shunting layer (4) outward for supporting the shunting muscle.
3, Separating sieve tube according to claim 1 and 2 is characterized in that: spacing support ring (6) has three, and the axial distance of adjacent two spacing support rings (6) equates.
