Abstract
A sub connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well. The sub includes a housing that prevents a well fluid from entering inside the housing; a plug that covers a hole made in a wall of the housing; and an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub.
Claims23
A sub that connects a gun string to a hydraulically activated setting tool for setting an auxiliary tool in a well, the sub comprising:
- a housing that prevents a well fluid from entering inside the housing;
- a plug that covers a hole made in a wall of the housing;
- and
- an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between an outside and the inside of the sub,
- wherein the housing has a first end configured to be attached to the gun string, which has plural shaped charges, and a second end configured to be attached to the hydraulically activated setting tool.
A gun assembly for use in a well, the gun assembly comprising:
- a gun string having plural shaped charges;
- a sub connected with one end to the gun string;
- and
- a hydraulically activated setting tool for setting an auxiliary tool in the well, the hydraulically activated setting tool being attached to a second end of the sub,
- wherein the sub includes,
- a housing that prevents a well fluid from the well from entering inside the housing,
- a plug that covers a hole made in a wall of the housing, and
- an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between the well and the inside of the sub.
A tool for use in a well, the tool comprising:
- a sub configured to be connected with one end to a gun string;
- and
- a hydraulically activated setting tool for setting an auxiliary tool in the well, the hydraulically activated setting tool being attached to a second end of the sub,
- wherein the sub includes,
- a housing that prevents a well fluid from the well from entering inside the housing,
- a plug that covers a hole made in a wall of the housing, and
- an explosive mechanism located inside the housing and configured to break the plug to open the hole to achieve fluid communication between the well and the inside of the sub.
