Abstract
Examples of the present disclosure relate to 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.
Claims20
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;
- a pressure adjustable member being configured to compress and elongate to apply a force against the sliding seal in a direction towards a proximal end of the tool, the pressure adjustable member being positioned between the sliding seal and a distal end of the tool, wherein the pressure 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 pressure adjustable member compresses;
- a chamber positioned between the sliding seal and the proximal end of the tool, wherein the chamber changes in size responsive to the pressure adjustable member compressing or elongating.

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 pressure adjustable member responsive to increasing the fluid flow rate;
- elongating the pressure adjustable member responsive to decreasing the fluid flow rate;
- applying a force via the pressure adjustable member in a direction towards a proximal end of the tool, the pressure 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 pressure adjustable member compressing or elongating.
