摘要： An apparatus for deploying and activating a downhole tool activated by an explosive charge such as a drill pipe cutter or hole puncher. The apparatus includes a sealing member with an external wedge-shaped profile that forms a metal-to-metal partial seal with a profile at the top end of a pipe joint in a drill pipe string. The apparatus includes an impact force absorbing device that maintains a firing rod in a non-actuated position during impact of the apparatus. The apparatus includes a differential pressure piston that actuates at a pre-determined well bore pressure to release the firing rod to activate the downhole tool.

摘要： In the representative embodiments of the several methods and apparatus of the invention, a barrier formed of a low-temperature fusible metal alloy having a selected melting point greater than the anticipated well bore temperatures is arranged between a receptor explosive and a typical electrically-initiated detonator enclosed in a housing for blocking the transmission of detonation forces from the detonator to the receptor explosive until the barrier has been heated by an electrical heater adjacent to the barrier. By selecting a fusible metal alloy which has a melting point higher than the known temperatures of the well bore fluids, when the tool is exposed to those elevated temperatures, the barrier will be predictably maintained in its solid state to continue blocking the detonation path of the donor explosive if the heater fails thereby allowing the well tool carrying the explosives to be safely recovered from the well bore.

摘要： In the representative embodiments of the several methods and apparatus of the invention disclosed herein, a movable detonating member is arranged to be selectively impelled against an impact-responsive detonator on a well bore perforator having one or more explosive devices. The movable detonating member is initially restrained from moving in relation of the tool body by a heat-responsive material which, in one embodiment, is operative to release the detonating member when an electrical heater on the tool is initiated from the surface for melting the bonding material or, in another embodiment, releases the detonating member when the material melted by elevated well bore temperatures. Other safety measures disclosed herein include temperature-sensitive barriers which, in one embodiment, prevents the movement of the detonating member against the explosive detonator until the material in the barrier is changed by elevated well bore temperatures as well as a second embodiment that precludes the transmission of detonating forces from the detonator and other explosives in the train of explosives on the bore perforator.

摘要： In the representative embodiments of the several methods and apparatus of the invention, a barrier formed of a low-temperature fusible metal alloy having a selected melting point is arranged between the donor and receptor explosives in an otherwise-typical detonator for reliably blocking the transmission of detonation forces from the donor explosive to the receptor explosive until the detonator has been subjected to well bore temperatures which are greater than the melting point of the fusible alloy. By selecting a fusible metal alloy which has a melting point less than the known temperatures of the well bore fluids, when the tool is exposed to those elevated temperatures, the barrier will be predictably transformed to its liquid state thereby allowing the liquid alloy to flow to a non-blocking position away from the detonation path of the donor explosive. In an alternative manner of carrying out the new and improved methods and apparatus of the invention, means are provided to return the fluent fusible metal alloy to its initial detonation-blocking position between the explosives so that the fusible metal alloy will again provide an effective barrier for reliably preventing the detonation of the receptor explosive as the well tool is subsequently recovered from the well bore.

摘要： A downhole plug and a method of releasing a portion of the plug. The plug has a run-in configuration, a deployed configuration, and a released configuration. The plug includes a mandrel, a bull nose, and a cone and an expandable slip. The expandable slip has an external gripping surface. The plug includes an inner and outer sleeve, where the outer sleeve is concentric around the inner sleeve and the inner sleeve is concentric with the mandrel. The inner sleeve is slidable about but releasingly coupled to the mandrel. The inner sleeve is slidable about the outer sleeve but releasingly coupled to the outer sleeve in both the run-in configuration and in the deployed configuration. The inner sleeve is coupled with the mandrel in the run-in configuration and in the deployed configuration, but uncoupled and slidable about the mandrel in the released configuration.
