Abstract

A perforating gun brake includes a tubular housing, an annular piston and a mandrel. A first end of the piston is telescopically received in an interior bore at a second end of the tubular housing. The mandrel extends through an interior bore of the piston into the interior bore of the tubular housing. An hydraulic fluid chamber is formed in the interior bore of the tubular housing. A spring biases the piston toward a first end of the mandrel. The movement of the piston along the mandrel is resisted by hydraulic fluid in the hydraulic fluid chamber. An explosive charge is positioned on a first sealing assembly for the hydraulic chamber. Several gripping members are pivotally mounted to an exterior surface of the piston. The gripping members are movable between a retracted position and a deployed position. The gripping members are moved to the deployed position by a deploying collar that is released in response to pressure exerted upon detonation of the perforating gun. The deploying collar holds the gripping members in the deployed position until the first sealing assembly is removed by detonation of the charge, thereby allowing hydraulic fluid to escape from the hydraulic chamber.
As the hydraulic chamber is emptied of hydraulic fluid the piston moves along the mandrel. The movement of the piston along the mandrel moves the gripping members away from the deploying collar allowing the gripping members to return to the retracted position.
