초록 ▼

Perforating assemblies and perforating safety systems capable of being disposed in a wellbore for hydrocarbon fluid production are described. The perforating assemblies can include an isolation device that is capable of preventing a denotation train when the assemblies are in a first orientation and allowing a denotation train when the perforating assemblies are in a second orientation. The isolation device can be automatically reoriented or reconfigured upon a change in the orientation of the perforating assembly.

대표청구항 ▼

1. A perforating assembly capable of being disposed in a bore of a subterranean formation, the perforating assembly comprising: an isolation device that is configured to provide a solid obstruction between the entirety of a first detonation train component and a second detonation train component in a first position, wherein the solid obstruction is configured to prevent a detonation train when the perforating assembly is in a first orientation and is movable to a second position for allowing the first component to directly contact the second component for causing the detonation train when the perforating assembly is in a second orientation,wherein the isolation device comprises a substantially spherical structure. 2. The perforating assembly of claim 1, wherein the isolation device comprises the substantially spherical structure and the substantially spherical structure is configured to cooperate with a sealing device to prevent the detonation train when the perforating assembly is in the first orientation. 3. The perforating assembly of claim 2, wherein the sealing device comprises at least one of an O-ring, a gasket, or a material made from silicone. 4. The perforating assembly of claim 1, wherein the isolation device comprises the substantially spherical structure and the substantially spherical structure is configured to be in the second position when the perforating assembly is in the second orientation. 5. The perforating assembly of claim 1, wherein the isolation device is configured to be in the first orientation or the second orientation depending on gravity. 6. A perforating safety system for use in a subterranean well, the perforating safety system comprising: a perforating assembly including a perforating gun, a firing head, and an isolation device, wherein the isolation device is configured to (i) provide a solid obstruction at a first position between the perforating gun and the entirety of the firing head, wherein the solid obstruction is configured to selectively prevent transfer of detonation from the firing head to the perforating gun and (ii) be positioned in a configuration to move the solid obstruction to a second position for allowing the transfer of the detonation,wherein the configuration of the isolation device is gravity-dependent. 7. The perforating safety system of claim 6, wherein the isolation device is configured to allow the transfer of the detonation when the perforating assembly is oriented in a substantially horizontal orientation. 8. The perforating safety system of claim 6, wherein the isolation device comprises a substantially spherical structure.
