An injection distribution device, comprising:
- a first baffle having a plurality of first openings;
- and
- a second baffle having a plurality of second openings, wherein at least a portion of the second baffle overlap with the first baffle, and the plurality of second openings are arranged so that flow resistance of through the second baffle varies along a length of the second baffle.
An injection assembly, comprising:
- a base pipe including an inject port;
- a screen member surrounding the base pipe;
- and
- an injection distribution device disposed between the base pipe and the screen member, wherein the injection distribution device comprises:
- a first baffle having a plurality of first openings formed therethrough;
- and
- a second baffle having a plurality of second openings formed therethrough, wherein at least a portion of the first baffle overlaps with the second baffle
A method for supplying a fluid into a formation zone, comprising:
- injecting the fluid from an interior of a base pipe to an exterior of the base pipe through an inject port formed through the base pipe;
- directing the flow of fluid from the port along a baffle portion disposed around the base pipe, wherein the baffle portion includes a plurality of openings configured to vary the flow resistance through the baffle portion along a length of the baffle portion;
- allowing the fluid to selectively flow through the plurality of openings in the baffle portion;
- and
- flowing the fluid from the baffle through a screen mechanism to the formation zone.
