Abstract

A shape memory material is used for a power spring in a subsurface safety valve. The spring is sized for the force it will deliver when it goes past its transition temperature and reverts to an original shape. The force released by having the spring pass its transition temperature holds the valve closed against hydrostatic pressure. Since the force exerted by the spring does not increase as the valve opens less force is required to hold the valve in the open position, thus lowering opening pressure. The trigger to cross the transition temperature comes from the expected temperature of well fluids at the mounting position of the subsurface safety valve. Other downhole applications are anticipated.

Claims

AMENDED CLAIMS received by the International Bureau on 13 February 2009 (13.02.2009).
1. A downhole tool operable from a well surface, comprising: a body comprising a hydraulic actuation system therein operably connected to at least one control line connection ; a movable member in a passage through said body selectively operated between a first and a second position by said actuation system and a biasing member acting on said movable member to change the movable member position in the event of removal or loss of hydraulic pressure to said actuation system, the output force of said biasing member is increased, beyond an initial value upon assembly into said body, by exposure to well fluids.
2. The tool of claim 1, wherein: said exposure is to the temperature of well fluids.
3. The tool of claim 2, wherein: said biasing member comprises at least one spring.
4. The tool of claim 3, wherein: said at least one spring is made from a shape memory alloy.
5. The tool of claim 4, wherein: said movable member comprises a flow tube in a subsurface safety valve.
6. The tool of claim 4, further comprising: a torsion spring on a pivot of a flapper in a subsurface safety valve and said torsion spring is made from a shape memory alloy.
7. The tool of claim 4, further comprising: an equalizer valve spring in a flapper in a subsurface safety valve and said equalizer spring is made from a shape memory alloy.
8. The tool of claim 7 , further comprising: a torsion spring on a pivot of a flapper in a subsurface safety valve and said torsion spring is made from a shape memory alloy.
9. Canceled
10. The tool of claim 4, wherein: said shape memory material is raised above its transition temperature only by the normal temperature of well fluid.
AMENDED SHEET (ARTICLE 19)
9
11. The tool of claim 4, wherein: said at least one spring comprises a plurality of springs with at least one spring not being made from a shape memory alloy.
12. The tool of claim 4, wherein: said spring provides a near linear force along the movement range of said movable member.
13. The tool of claim 12, wherein: said movable member comprises a flow tube in a subsurface safety valve.
