The present application describes a velocity chamber to regulate a velocity of fluid between an outer diameter of a piston, and an insert to limit, reduce, etc. erosion against the tool and casing.
1. A tool for fracturing, comprising:
a tool inner diameter extending across a hollow chamber within the tool,
a piston with having an outer diameter, the piston being configured to move within the tool inner diameter;
a chamber formed between the tool inner diameter and the outer diameter based on the position of the piston within the tool inner diameter, the chamber having a variable cross-sectional area between the tool inner diameter and the outer diameter of the piston, the chamber being configured to control a velocity and fluid flow rate of fluid flowing between the tool inner diameter and the outer diameter of the piston based on the variable cross-sectional area between the tool inner diameter and the outer diameter of the piston.
2. The tool of claim 1 , wherein the piston includes a first tapered sidewall configured to increase the variable cross-sectional area between the outer diameter of the piston and the tool inner diameter, and a second tapered sidewall configured to decrease the variable cross-sectional area between the outer diameter and the tool inner diameter, wherein the outer diameter of the piston is a variable distance.
3. The tool of claim 1 , further comprising:
ports extending from the tool inner diameter to a tool outer diameter, wherein the second tapered sidewall is configured to control a direction of fluid flow from the chamber into the ports.
4. The tool of claim 1 , wherein in a first mode a first end of the piston is positioned adjacent to the tool inner diameter.
5. The tool of claim 4 , wherein in a second mode the first end of the piston is positioned away from the tool inner diameter.
6. The tool of claim 5 , wherein in the second mode the chamber includes an inlet zone, and expansion zone, and an outlet zone, the tool inner diameter having a first diameter in the inlet zone, a second inner diameter in the expansion zone, and a third inner diameter in the outlet zone.
7. The tool of claim 6 , wherein when fluid flows into the inlet zone the fluid has a first flow rate and when fluid flows through the outlet zone the fluid has a second flow rate, the second flow rate being slower than the first flow rate.
8. The tool of claim 6 , wherein a first cross sectional area of the inlet zone is smaller than a second cross sectional area of the expansion zone.
9. The tool of claim 5 , wherein the piston is configured to move between the first mode and the second mode based on a fluid flow rate through the tool inner diameter.
10. The tool of claim 1 , wherein a second end of the piston is positioned adjacent to the tool inner diameter.
11. A method for using a tool for fracturing, comprising:
moving a piston with having an outer diameter within a tool inner diameter, the tool inner diameter extending across a hollow chamber within the tool;
forming a chamber between the tool inner diameter and the outer diameter based on the position of the piston within the tool inner diameter, the chamber having a variable cross-sectional area between the tool inner diameter and the other diameter of the piston;
controlling, via the chamber, velocity and a fluid flow rate of fluid flowing between the tool inner diameter and the outer diameter based on the variable cross-sectional area between the tool inner diameter and the outer diameter of the piston.
12. The method of claim 11 , further comprising:
increasing the variable cross-sectional area between the outer diameter and the tool inner diameter via a first tapered sidewall;
decreasing the variable cross-sectional area between the outer diameter of the piston and the tool inner diameter via a second tapered sidewall, wherein the outer diameter of the piston is a variable distance.
13. The method of claim 11 , further comprising:
forming ports that extend from the tool inner diameter to a tool outer diameter, wherein the second tapered sidewall is configured to control a direction of fluid flow from the chamber into the ports.
14. The method of claim 11 , further comprising:
positioning, in a first mode, a first end of the piston adjacent to the tool inner diameter.
15. The method of claim 14 , further comprising:
positioning, in a second mode, the first end of the piston away from the tool inner diameter.
16. The method of claim 15 , wherein in the second mode the chamber includes an inlet zone, and expansion zone, and an outlet zone, the tool inner diameter having a first diameter in the inlet zone, a second inner diameter in the expansion zone, and a third inner diameter in the outlet zone.
17. The method of claim 16 , wherein when fluid flows into the inlet zone the fluid has a first flow rate and when fluid flows through the outlet zone the fluid has a second flow rate, the second flow rate being slower than the first flow rate.
18. The method of claim 16 , wherein a first cross sectional area of the inlet zone is smaller than a second cross sectional area of the expansion zone.
19. The method of claim 15 , further comprising:
moving the piston between the first mode and the second mode based on a fluid flow rate through the tool inner diameter.
20. The method of claim 11 , wherein a second end of the piston is positioned adjacent to the tool inner diameter.
