Abstract
Systems and methods to maintain constant pressure within a chamber within a tool via a sliding seal, wherein the seal moves to increase or decrease the size of the chamber.
Claims16
A fracturing system comprising:
- a first set of nozzles positioned at a first offset within a tool;
- a second set of nozzles positioned at a second offset within the tool;
- a sliding seal positioned within an inner diameter of the tool, the sliding seal being configured to move within a tool;
- an adjustable member being configured to compress and elongate based on variations in pressure to apply a force against the sliding seal in a direction towards a proximal end of the tool, the adjustable member being positioned between the sliding seal and a distal end of the tool, wherein the adjustable member compresses responsive to increasing a fluid flow rate through the inner diameter of the tool, and the sliding seal is configured to move towards the distal end of the tool when the adjustable member compresses;
- and
- a chamber positioned between the sliding seal and the proximal end of the tool, wherein the chamber changes in size responsive to the adjustable member compressing or elongating,
- wherein the adjustable member is configured to elongate responsive to decreasing the fluid flow rate through the inner diameter of the tool, and the chamber decreases in size when the adjustable member compresses, wherein pressure within the chamber remains substantially constant when the fluid flow rate through the inner diameter of the tool changes by automatically changing the size of the chamber.

A method utilizing a fracturing system comprising:
- positioning a sliding sleeve within an inner diameter of a tool, the tool including a first set of nozzles positioned at a first offset within a tool and a second set of nozzles positioned at a second offset within the tool;
- changing a fluid flow rate through the inner diameter of the tool;
- compressing a adjustable member responsive to increasing the fluid flow rate;
- elongating the adjustable member responsive to decreasing the fluid flow rate, wherein the adjustable member is configured to compress or elongate based on pressure;
- applying a force via the adjustable member in a direction towards a proximal end of the tool, the adjustable member being positioned between the sliding seal and a distal end of the tool;
- changing a size of a chamber positioned between the sliding seal and the proximal end of the tool responsive to the adjustable member compressing or elongating;
- decreasing the size of the chamber when the adjustable member compresses;
- maintaining a substantially constant pressure within the chamber when the fluid flow rate through the inner diameter of the tool changes by automatically changing the size of the chamber.
