Downhole treatment tool and method

Abstract

A downhole treatment tool including a housing having one or more openings and one or more ports. A sleeve disposed in movable relationship to the housing. The sleeve having one or more apertures that upon movement of the sleeve are selectively positionable among positions of unaligned, aligned with the one or more openings or aligned with the one or more ports. A method for treating a downhole location.

1 . A downhole treatment tool comprising:
 a housing having one or more openings and one or more ports;   a sleeve disposed in movable relationship to the housing, the sleeve having one or more apertures that upon movement of the sleeve are selectively positionable among positions of unaligned, aligned with the one or more openings or aligned with the one or more ports.   
     
     
         2 . The tool as claimed in  claim 1  further comprising a biasing member disposed to oppose alignment of the one or more apertures with the one or more openings or the one or more ports. 
     
     
         3 . The tool as claimed in  claim 2  wherein the biasing member is a spring. 
     
     
         4 . The tool as claimed in  claim 1  wherein the one or more openings are configured to produce a jet of fluid upon the application of a pressurized fluid therethrough. 
     
     
         5 . The tool as claimed in  claim 1  wherein the sleeve is closed at a downstream end thereof. 
     
     
         6 . The tool as claimed in  claim 1  wherein the sleeve is configured to respond to flowing fluid therethrough to move positionally. 
     
     
         7 . The tool as claimed in  claim 6  wherein the sleeve is configured to respond to fluid friction. 
     
     
         8 . The tool as claimed in  claim 6  wherein the sleeve is configured to respond to fluid pressure. 
     
     
         9 . The tool as claimed in  claim 1  configured to be electromechanically or electromagnetically actuated. 
     
     
         10 . The tool as claimed in  claim 1  wherein the sleeve further includes an anchoring arrangement. 
     
     
         11 . The tool as claimed in  claim 10  wherein the anchoring arrangement is mechanical. 
     
     
         12 . The tool as claimed in  claim 11  wherein the anchoring arrangement is a collet. 
     
     
         13 . The tool as claimed in  claim 10  wherein the anchoring arrangement is fluidic. 
     
     
         14 . The tool as claimed in  claim 10  wherein the anchoring arrangement includes a piston movable within a cylinder of the housing, the piston is configured to pass a large volume of fluid in one direction that it can in an opposite direction. 
     
     
         15 . The tool as claimed in  claim 14 , wherein the piston includes a check valve. 
     
     
         16 . The tool as claimed in  claim 10  wherein the housing includes an anchoring complement to the anchoring arrangement. 
     
     
         17 . The tool as claimed in  claim 10  wherein the anchoring arrangement 
     
     
         18 . A downhole system comprising:
 a tubular string;   a treatment tool having a housing having one or more openings and one or more ports;   a sleeve disposed in movable relationship to the housing, the sleeve having one or more apertures that upon movement of the sleeve are selectively positionable among positions of unaligned, aligned with the one or more openings or aligned with the one or more ports.   
     
     
         19 . A method for treating a downhole location comprising:
 applying one or more of a pressure and a flow of a treatment fluid to a treatment tool that includes a housing having one or more openings and one or more ports and a sleeve disposed in movable relationship to the housing, the sleeve having one or more apertures that upon movement of the sleeve are selectively positionable among positions of unaligned, aligned with the one or more openings or aligned with the one or more ports;   aligning the one or more apertures with the one or more openings;   jetting fluid through the one or more openings;   eroding a structure radially outwardly of the housing;   aligning the one or more apertures with the one or more ports;   treating the downhole location.   
     
     
         20 . The method as claimed in  claim 19  wherein the structure is an open borehole. 
     
     
         21 . The method as claimed in  claim 19  wherein the structure is a tubular. 
     
     
         22 . The method as claimed in  claim 19  wherein the treating is fracturing. 
     
     
         23 . A downhole treatment tool comprising:
 a housing having one or more openings and one or more ports;   a flow tube disposed in movable relationship to the housing; and   a valve member actuable by the flow tube.   
     
     
         24 . The downhole tool as claimed in  claim 23  configured to be electromechanically or electromagnetically actuated.
