Patent

CA 2669739

An actuator device for setting a downhole tool (100) is disclosed. The actuator device includes a gas releasing material (60) that releases a gas when activated by a solvent or other activator. The gas produced due to the contact with the activator is captured within a chamber (14) in the downhole tool. As a result, gas pressure builds up inside the tool to move a piston (12) and cause setting of the downhole tool.

L'invention concerne un dispositif actionneur destiné à actionner un outil de fond (100). Le dispositif actionneur de l'invention comprend une matière à dégagement de gaz (60) dégageant un gaz lorsqu'elle est activée par un solvant ou par un autre activateur. Le gaz produit par la mise en contact de cette matière avec l'activateur est capturé à l'intérieur d'un compartiment (14) de l'outil de fond. Ainsi, la pression augmente à l'intérieur de l'outil et déplace un piston (12) qui actionne l'outil de fond.
