A shut-in valve tool for use in a well has a tool body defining a flow path for the flow of well fluid from outside the tool through the tool body to another part of the well. The tool has an inlet port defined in the tool body through which well fluid must flow to enter the flow path. The tool has a sliding valve member located within the tool body and moveable between a first position in which the inlet port is open, and a second position in which the inlet port is blocked. The tool has a supply of compressed fluid and an actuating mechanism which uses the compressed fluid for driving the sliding valve member from the first position to the second position.

Downhole fast-acting shut-in valve system

A bridge plug tool for use in a well, comprising: a tool body; a mandrel () extending through the tool body; a setting sleeve () positioned on the tool body; a packer module () located below the setting sleeve, the packer module having an expanded position in which its outer surface is expanded radially with respect to the tool body and a contracted position in which its outer surface is substantially the same as that of the tool body; and an anchor module () located below the packer module, the anchoring module comprising anchor elements moveable between an expanded position in which the anchor elements extend radially from the tool body and a contracted position in which the anchor elements are substantially aligned with the surface of the tool body; wherein the mandrel extends through the sleeve, packer module and anchor module; the mandrel and setting sleeve are relatively moveable between an axially extended position and an axially contracted position; and wherein the mandrel and setting sleeve engage the anchor module and packer module such that relative movement of the mandrel and setting sleeve between the axially extended and axially contracted positions correspondingly moves the anchor module and packer module between the respective contracted and expanded positions. The use of the sleeve and mandrel arrangement allows setting and release mechanisms to be protected from the external environment of the tool.
