Abstract
An inflatable down hole bag for insertion in a bore hole, comprising a sealed inflatable body for holding an inflation fluid; a first substance within the sealed inflatable body; a second substance separated from the first substance within the sealed inflatable body; and a release for allowing the second substance to contact the first substance; wherein release of the second substance causes an inflation fluid producing reaction within the sealed inflatable body, thereby inflating the inflatable body, the sealed inflatable body being vacuum sealed so as to hold in place one or both of the first and second substances prior to the release of the second substance.
Claims21
An inflatable down hole bag for insertion in a bore hole, comprising:
- a sealed inflatable body for holding an inflation fluid;
- a solid state of matter first substance within the sealed inflatable body;
- a liquid state of matter second substance separated from the first substance within a container, which is within the sealed inflatable body;
- and
- a release for allowing the second substance to exit the container to contact the first substance;
- wherein release of the second substance causes an inflation fluid producing reaction within the sealed inflatable body, thereby inflating the inflatable body, the sealed inflatable body being vacuum sealed so as to hold in place the first substance and container holding the second substance prior to the release of the second substance, wherein the vacuum sealed inflatable body defines a first chamber holding the first substance in place and a second chamber holding the container in place, wherein the release acts as a closure providing the separation of the second substance from the first substance when the closure is closed, and the release provides a fluid connection between an inside of the container and the first chamber, so that the second substance is released to contact the first substance, when the closure is opened.
A method of inflating a down hole bag, comprising:
- providing an inflatable bag having a sealed inflatable body for holding an inflation fluid, the body comprising a solid first substance and a liquid second substance in a container, the first and second substance being separated by a release, wherein the sealed inflatable body is vacuum sealed holding the first substance in place and container holding the second substances in place;
- activating the release allowing the second substance to come into contact with the first substance causing an inflation fluid producing reaction within the inflatable body, thereby inflating the inflatable body.
A method of forming an inflatable down hole bag, comprising:
- placing a first solid substance and a container holding a liquid second substance within a sealable inflatable body;
- and
- vacuum sealing the inflatable body retaining the first substance and the container in place relative to each other within the inflatable body,
- wherein the first substance and container are placed in a manner in which the first and second substances are separated until released.
