Abstract
Method and down-hole tool for use inside a well, the down-hole tool including a housing; an anchoring arm rotatably attached to the housing and configured to move between an open position and a closed position; a spring block configured to have a central part that moves along a longitudinal axis (X) of the housing which results in the movement of the anchoring arm between the open or closed positions; and an actuating mechanism connected to the central part and configured to move the central part along the longitudinal axis. The spring block is detachably attached to the housing.
Claims20
A down-hole tool for use inside a well, the down-hole tool comprising:
- a housing;
- an anchoring arm rotatably attached to the housing and configured to move between an open position and a closed position;
- a spring block configured to have a central part that moves along a longitudinal axis (X) of the housing which results in the movement of the anchoring arm between the open or closed positions;
- and
- an actuating mechanism connected to the central part and configured to move the central part along the longitudinal axis,
- wherein the spring block is detachably attached to the housing.
A down-hole system for measuring a parameter associated with a well, the down-hole system comprising:
- a controller located at the surface of the well;
- at least one down-hole tool;
- and
- a connecting cable connecting the controller to the at least one down-hole tool,
- wherein the first down-hole tool includes,
- a housing,
- an anchoring arm rotatably attached to the housing and configured to move between an open position and a closed position,
- a spring block configured to have a central part that moves along a longitudinal axis (X) of the housing and a movement of the central part results in the movement of the anchoring arm between the open or closed positions, and
- an actuating mechanism connected to the central part and configured to move the central part along the longitudinal axis,
- wherein the spring block is detachably attached to the housing.
A method for changing a biasing force for a down-hole tool for use inside a well, the method comprising:
- removing an anchoring arm that is rotatably attached to a housing of the tool;
- detaching a cap from a central part of a spring block;
- and
- reversing an orientation of the spring block,
- wherein a movement of the central part results in the movement of the anchoring arm between open and closed positions.
