Downhole tool actuation having a seat with a fluid by-pass
First Claim
Patent Images
1. A downhole tool comprising:
- a tubular body having a bore formed therein and at least one fluid passage in a wall of the tubular body, the bore defining a fluid path;
a reciprocating sleeve configured to translate from a first location to a second location within the bore, the reciprocating sleeve having at least one guide protrusion; and
a guided sleeve located within the bore, the guided sleeve being axially constrained, the guided sleeve having at least one guide recess and at least one port, the guide recess configured to receive the at least one guide protrusion and the guided sleeve being substantially coaxial with the reciprocating sleeve, wherein the at least one guide recess is configured to cause the guided sleeve to rotate in a first direction in response to the reciprocating sleeve being translated from the first location to the second location and cause the sleeve to rotate in the first direction in response to the reciprocating sleeve being translated from the second location to the first location, wherein the rotation of the guided sleeve causes the at least one port to align with the at least one fluid passage.

Abstract
A downhole tool actuation system has a fluid path defined by a bore formed within a tubular body of a tool. A reciprocating sleeve is located within the bore and the sleeve has a segmented seat with a fluid by-pass. At least one seat segment is positioned by an outer diameter of the sleeve to complete the seat, and a relief is formed in a wall adjacent the outer diameter of the sleeve. When the seat is occupied by an obstruction, only a portion of the fluid path is obstructed and fluid impinging the obstruction causes the sleeve to move in the direction of flow until the at least one segment is relieved by the relief thereby releasing the obstruction.
