摘要： In the context of downhole tools, bulkhead igniter assemblies having snap-on insulators are disclosed. In some embodiments the bulkhead igniter assemblies have a bulkhead with a first end formed with at least one ridge or groove, a pressure block, a setting tool, and a snap-on insulator. The snap-on insulator has an annular body having a tubular channel through a center portion. Ridges or groves on the snap-on insulator mate with ridges or grooves on the bulkhead igniter to hold the snap-on insulator in place on the bulkhead igniter by interaction of the ridge or groove of the snap-on insulator with the ridge or groove on the first end of the bulkhead igniter. Other embodiments are disclosed.

摘要： In the context of downhole tools, fixed volume power charge initiator assemblies and bottom hole assemblies utilizing fixed volume power charge initiator assembly are disclosed. The fixed volume power charge initiator assembly has a pressure bulkhead coupled to a cartridge. The cartridge includes an igniter disposed within an interior cavity of the cartridge. When used in a bottom hole assembly the fixed volume power charge initiator assembly is located in a setting tool adjacent to a power charge located within a combustion chamber of the setting tool. The combustion chamber and the cartridge together define a fixed total combustion volume. In some instances, the fixed volume power charge initiator assembly includes a power charge detector switch. Other assemblies are discussed.

摘要： A downhole tool includes a plurality of mechanical components with some that move relative to others. The tool includes an annular charge cannister associated with the plurality of mechanical components that delivers a gas to move mechanical components. The annular charge cannister includes an annular chamber having a back wall, an interior sidewall, an exterior sidewall, and an open side opposite the back wall. The back wall and the interior sidewall and exterior sidewall form an interior space, and a power charge is disposed within the interior space of the annular chamber. An annular lid is sized and configured to mate with the open side of the annular chamber. The charge cannister may include an ignition port formed in the annular lid for receiving an igniter.

摘要： A gas-operated, fixed-volume, downhole setting tool includes a mandrel having an upper portion and a lower portion. The mandrel has a first end on the upper portion and a second end on the lower portion. The mandrel also includes an interior combustion chamber having a first end proximate to the first end of the mandrel and having an interior upper portion. The setting tool further includes a pressure bulkhead with a pressure igniter disposed in the mandrel at the first end of the mandrel in the interior upper portion of the mandrel. The pressure igniter is sealed to at least a first threshold pressure. The pressure bulkhead and pressure igniter form a seal on the first end of the mandrel and thereby define a fixed volume for combustion gases. Other settings tools and assemblies are presented.

摘要： In one instance, a dual-booster power charge is disclosed for use in a downhole setting tool, wherein the dual-booster power charge has at least a first and a second booster charge disposed within a sleeve and embedded in a main power charge. Each booster charge has one end face that is exposed at the end of the dual-booster power charge. Each booster charge may have a first dimension near the end face that is smaller than a second dimension near the end of the booster charge that is not exposed. In some instances, the booster charges have a charge retention portion and a primary body portion, and a cross sectional diameter of the charge retention portion is larger than a cross sectional dimension of the primary body portion. Other dual-booster power charges and booster charges are disclosed.

摘要： A setting tool includes a barrel piston that is configured to couple to a setting sleeve and defines a working surface and a vent port. An upper mandrel is disposed within the barrel piston and defines a power charge chamber that is configured to receive a power charge and includes an upper threaded portion, a lower internal thread, and a plurality of axial discharge ports disposed circumferentially around the lower internal thread. The plurality of axial discharge ports are in fluid communication at one end with the power charge chamber and at the other end with the working surface of the barrel piston. A lower mandrel has an upper end and a lower end, with the upper end in threaded engagement with the lower internal thread of the upper mandrel, and the lower end configured to couple to a frac plug. The power charge chamber includes an upper chamber and a lower chamber, with the lower chamber shaped to open to be in fluid communication with each of the plurality of axial discharge ports. The barrel piston is configured for axial displacement with respect to the upper mandrel to position the vent port in fluid communication with the power charge chamber.

摘要： Igniter assemblies for use with setting tools are disclosed. The igniter assemblies have an electronic heating element disposed adjacent to an energetic material within a setting tool. In some embodiments, the electronic heating element is a resistor or a PCB mounted resistor. Electrical connections are attached to the heating element to provide electrical current to activate the heating element. In some instances, the electrical heating element is disposed onto an insulator cap that is coupled to a pressure block attached to the setting tool, and in some instances the electronic heating element is attached to a non-explosive portion and the energetic material is disposed within an explosive portion. When the non-explosive portion and the explosive portion are assembled, the electronic heating element is adjacent to the energetic material. Other assemblies are described.

摘要： A setting tool for use in wells includes a mandrel formed with an interior combustion chamber. The setting tool further includes a barrel piston sized and configured to extend at least partially over an exterior of the mandrel and a shear device coupled to a portion of the mandrel and coupled to the barrel piston when in an in-line configuration. The mandrel includes an upper portion having a lead portion, an engagement portion, and a wrench-application portion. The wrench-application portion has a longitudinal length in the range of 1.5 to 3.0 to receive a wrench and avoid damage to the shear device. Other tools are disclosed.
