INTERMEDIATE DISCONNECTION TOOL TO BE PLACED IN A SHUTTLE LOWERED INTO A WELL FOR EXPLOITING A FLUID, AND RELATED SHUTTLE AND METHOD

摘要

The invention relates to a tool including a top portion (64) and a bottom portion (62) which are movably mounted relative to each other between a connected position and a totally disconnected position. The tool includes an immobilization member (140) that is releasable from the top portion (64) relative to the bottom portion (62), a member (142) for releasing the immobilization member (140), and a mechanism (144) for moving the release member (142) housed in the tool (54). The moving mechanism (144) includes an actuator (184) and a means for receiving a control signal. The moving mechanism (144) includes a member (180) for resiliently urging the release member (142) into the release position thereof and also includes a member (182) for retaining the release member (142) in an activation position contacting the urging member. The actuator (184) is suitable for releasing the retaining member (182) after receiving the control signal.
