Abstract
The present invention relates to an improved method and system for perforating, slotting, and cutting steel and subterranean rock; and also for fracturing a subterranean formation to stimulate the production of desired fluids therefrom. The invention involves a fluid jetting device with a sleeve composed of a hard material. The sleeve includes at least one hole and a fluid flowing through the jetting device is emitted through the hole in the sleeve.
Claims19
A jetting tool comprising:
- a sleeve for bearing and delivering a high-pressure fluid comprising a plurality of substantially cylindrical sleeve parts that interface at least longitudinally to form a sleeve wall, wherein at least one of the sleeve parts has a first hole extending radially therethrough;
- a first holder that is substantially cylindrical and that longitudinally interfaces a first sleeve part of the plurality of sleeve parts;
- a second holder that is substantially cylindrical and that comprises a first part that longitudinally interfaces a second sleeve part of the plurality of sleeve parts and a second part having a hole extending radially therethrough;
- wherein the first hole of the at least one sleeve part and the hole of the second holder are substantially aligned;
- wherein the sleeve comprises a material with a hardness greater than 75 Rockwell A;
- wherein a fluid flowing in the sleeve exits through the first hole and the hole of the second holder;
- and
- wherein each of the first holder, the second holder, and the sleeve comprise an inner substantially cylindrical surface that is radially disposed about a common axis and that is configured to directly bear high-pressure fluid.

A fluid jetting device comprising:
- a cylindrical body for bearing and delivering a high-pressure fluid, wherein the cylindrical body forms a cylindrical body wall having a first orifice extending radially therethrough, wherein the cylindrical body has a hardness greater than 75 Rockwell A;
- a first holder that is substantially cylindrical and that longitudinally interfaces a first end of the cylindrical body;
- a second holder that is substantially cylindrical, wherein the second holder comprises a first part that longitudinally interfaces a second end of the cylindrical body and a second part;
- an orifice extending radially through one of the holders;
- wherein the first orifice and the orifice of the holders may be substantially aligned;
- wherein a fluid flowing through the cylindrical body exits through the first orifice and the orifice of the holders;
- and
- wherein each of the first holder, the second holder, and the cylindrical body comprise an inner substantially cylindrical surface that is radially disposed about a common axis and that is configured to directly bear high-pressure fluid.
