Diffuser assembly
View Patent ↗A diffuser assembly is provided, comprising a diffuser adapted to reside within a conduit, having an upper member mountable within the conduit and having a fluid inlet port, and a lower section having a diffuser screen; a plurality of stationary diffusing members below the fluid inlet port, wherein the diffusing members are radially oriented relative to a central axis of the diffuser; and (c) a centralizing member above the diffuser screen having a diameter greater than the diffuser screen. The diffuser screen is a cylinder having a plurality of diffuser slots formed therein and a bottom cap having a fluid port; and each of the plurality of diffusing members extends substantially parallel to the central axis.
1. A diffuser assembly, comprising:
(a) a diffuser adapted to reside within a conduit, having an upper mounting member mountable within the conduit and having a fluid inlet port, and a lower section having a diffuser screen;
(b) a plurality of stationary diffusing members below the fluid inlet port, wherein the diffusing members are radially oriented relative to a central axis of the diffuser; and
(c) a plurality of centralizing members above the diffuser screen having a diameter greater than the diffuser screen; and
wherein the diffuser screen is a cylinder having a plurality of diffuser slots formed therein and a bottom cap having a fluid port; and
wherein each of the plurality of diffusing members extends substantially parallel to the central axis and includes a diffusing edge.
2. The diffuser assembly of claim 1 , wherein a first set of diffusing members is mounted at a first selected height along the central axis of the diffuser screen, and wherein a second set of diffusing members is mounted at a second selected height along the central axis of the diffuser screen.
3. The diffuser assembly of claim 1 , wherein the diffusing members are mounted to the diffuser screen such that the diffusing edges are internal to the diffuser screen.
4. The diffuser assembly of claim 3 , wherein the plurality of centralizing members are adjacent to the diffuser screen.
5. The diffuser assembly of claim 4 , wherein each of the plurality of centralizing members extends between the mounting member and the bottom cap.
6. The diffuser assembly of claim 3 , further including a bottom diffusing device extending from the bottom cap internal to the diffuser screen, wherein the diffusing device includes a plurality of radially disposed diffusing edges.
7. The diffuser assembly of claim 1 , wherein the diffusing members are mounted to the diffuser screen such that the diffusing edges are external to the diffuser screen.
8. The diffuser assembly of claim 7 , further including a lower diffuser element below the diffuser screen, wherein the lower diffuser element is constructed from a slotted cylinder.
9. The diffuser assembly of claim 7 , further including a lower diffuser element below the diffuser screen, wherein the lower diffuser element is constructed from vertical rods.
10. The diffuser assembly of claim 7 , further including a diversion member disposed between the fluid inlet port of the mounting member and the diffuser screen.
11. The diffuser assembly of claim 1 , wherein the diffuser assembly is positioned within a downhole carrier sub inside a well bore.
