Abstract

Embodiments disclosed herein relate to a fluid distribution apparatus. The fluid distribution apparatus has a housing including an inlet configured to receive a drilling material, a first outlet configured to direct a first portion of the drilling material onto a first separatory surface, and a second outlet configured to direct a second portion of the drilling material onto a second separatory surface. The fluid distribution apparatus further includes a screen disposed within the housing and configured to separate solids from the second portion of the drilling material directed through the second outlet onto the second separatory surface.

First claim

What is claimed:

1. A fluid distribution apparatus comprising:
a housing comprising:
a first outer wall;
a second outer wall;
an inlet formed in the first outer wall of the housing;
a first outlet formed in the second outer wall,
a second outlet formed in the second outer wall; and
a screen having a plurality of perforations therethrough, the screen substantially vertically within the housing, and extending from a first corner of the housing at an angle between 30 and 60 degrees with respect to the first outer wall such that at least a portion of the screen is disposed between the inlet and the second outlet.

2. The fluid distribution apparatus of claim 1 , wherein the housing further comprises:
a third outlet formed in the second outer wall; and
a second screen disposed substantially vertically within the housing such that at least a portion of the screen is disposed between the inlet and the third outlet.

3. The fluid distribution apparatus of claim 1 , wherein the screen is disposed at an angle of about 45 degrees with respect to the first outer wall.

4. The fluid distribution apparatus of claim 1 , wherein the screen is coupled to the housing.

5. The fluid distribution apparatus of claim 1 , wherein the housing comprises a track disposed on a bottom surface of the housing and is configured to receive the screen within the track.

6. The fluid distribution apparatus of claim 1 , wherein the screen comprises at least one selected from a group consisting of a metal, a composite, a mesh, and a cloth.

7. The fluid distribution apparatus of claim 1 , wherein the fluid distribution apparatus is configured to couple to a vibratory separator.

8. The fluid distribution apparatus of claim 1 , wherein the housing further comprises a stepped bottom surface.

9. The fluid distribution apparatus of claim 1 , wherein at least a portion of the screen extends from a bottom surface of a housing to a height approximately equal to a height of the housing.

10. The fluid distribution apparatus of claim 1 , wherein the second outer wall is a bottom surface of the housing.

11. A method comprising:
receiving a drilling material through an inlet in a first wall of a housing;
directing a first portion of the drilling material through a first outlet in a second wall of the housing and onto a first separatory surface;
separating solids from a second portion of the drilling material by passing the drilling material through a substantially vertical screen disposed within the housing, thereby separating the second portion of the drilling material into solids and a filtered second portion;
directing the filtered second portion from the substantially vertical screen to a second outlet formed in the second wall, through the second outlet, and onto a second separatory surface.

12. The method of claim 11 , further comprising:
separating solids from a third portion of the drilling material by passing the drilling material through a second substantially vertical screen disposed within the housing, thereby separating the third portion of the drilling material into the solids and a filtered third portion of the drilling material; and
directing the filtered third portion from the second substantially vertical screen to a third outlet formed in the second wall, through the third outlet, and onto at least one of the second separatory surface or a third separatory surface.

13. The method of claim 12 , wherein the filtered third portion is directed to the third separatory surface, further comprising separating solids from the filtered second portion with the second separatory surface in parallel with separating solids from the filtered third portion with the third separatory surface.

14. The method of claim 11 , further comprising:
coupling the housing to a feed end of a shaker.

15. A fluid distribution system comprising:
a shaker configured to separate solids from a drilling fluid, wherein the shaker comprises a first deck and a second deck;
at least one motor coupled to the shaker, wherein the motor is configured to provide vibratory motion to the shaker; and
a fluid distribution apparatus coupled to a feed end of the shaker, wherein the fluid distribution apparatus comprises:
a housing having:
an inlet formed in a first outer wall:
a first outlet formed in a second outer wall to direct the drilling fluid to the first deck;
a second outlet formed in the second outer wall to direct the drilling fluid to the second deck; and
a screen disposed substantially vertically between the first outer wall and the second outer wall such that at least a portion of the screen is disposed between the inlet and the second outlet.

16. The fluid distribution system of claim 15 , wherein the shaker comprises a third deck, wherein the fluid distribution apparatus further comprises:
a third outlet formed in the second outer wall to direct drilling fluid to the third deck;
a second screen disposed substantially vertically between the first outer wall and the second outer wall such that at least a portion of the screen is disposed between the inlet and the third outlet.

17. The fluid distribution system of claim 16 , wherein the first deck of the shaker comprises a scalping deck, wherein the second deck of the shaker comprises a first primary deck, and wherein the third deck of the shaker comprises a second primary deck.

18. The fluid distribution system of claim 15 , wherein the drilling material comprises a gumbo, and wherein the fluid distribution apparatus is configured to couple to a gumbo separator.
