Simulating downhole flow through a perforation
A perforation test target is provided. The perforation test target includes a metal plate and a core sample adhered to the metal plate at one end. The perforation test target further including a first sleeve adhered to the core sample, where a flow impedance of each of a plurality of portions of the first sleeve is based on a predetermined impedance map.
1. A perforation test target, comprising:
a metal plate;
a core sample adhered to the metal plate at one end; and
a first sleeve adhered to the core sample, wherein the first sleeve is configured to transform a constant surface fluid pressure incident on an outside of the first sleeve to a non-constant fluid pressure distribution on a surface of the core sample when fluid is flowing.
2. The perforation test target of claim 1 , further comprising a cap portion engaging an end of the core sample opposite the metal plate, wherein a flow impedance of the cap portion varies from a center of the cap portion to an edge of the cap portion.
3. The perforation test target of claim 1 , wherein an impedance of the first sleeve varies only in the axial direction.
4. The perforation test target of claim 1 , wherein the first sleeve comprises a sheet rolled about the core sample.
5. The perforation test target of claim 4 , wherein a ratio of a major radius of the core sample to a minor radius of the core sample is between about 1.1 and about 2.
6. The perforation test target of claim 4 , wherein a flow impedance of the first sleeve varies only in an axial direction.
