摘要： A wireline release tool for downhole intervention, the tool including a housing having an electrical input and an electrical output; a pass-through switch located inside the housing and electrically connected between the electrical input and the electrical output; and a current limiter device located inside the housing and electrically connected between the electrical input and the electrical output. The pass-through switch is connected in parallel to the current limiter device, between the electrical input and the electrical output.

摘要： A switch assembly, which is part of a chain of switch assemblies. The switch assembly includes a micro-controller PB that has no address, a thru-line switch, and a detonator switch. The micro-controller PB is configured to directly communicate with an upstream or downstream switch assembly through a pulsing scheme, and the micro-controller PB receives no command from a surface controller.

摘要： A method for controlling a target switch assembly in a chain of switch assemblies includes distributing the chain of switch assemblies in a wellbore; placing a controller at a head of the wellbore; making a first decision, at the controller, to actuate a corresponding detonator of the target switch assembly; transmitting, from the controller to the target switch assembly, a fire command to activate the corresponding detonator; and making a second decision, locally, at the target switch assembly, to activate the detonator, after the fire command from the controller is received.

摘要： A switch assembly, which is part of a chain of switch assemblies, includes a communication unit (CU) configured to receive, from an external controller, a fire command to activate a detonator and a computing core (CC) configured to locally make a decision whether or not to activate the detonator, after receiving the fire command to activate the detonator.

摘要： A convertible and addressable switch assembly includes an interface (I/O) configured to connect to a controller along a telemetry system; and a processor connected to the interface (I/O). The processor is configured to receive a command from the controller, along the telemetry system, to change a first value of a mode status variable to a desired second value, wherein the first value is associated with a first operating mode of the switch assembly and the second value is associated with a second operating mode, which is different from the first operating mode; change the first value to the second value within the switch assembly; and store in a non-volatile memory, at the switch assembly, the second value of the mode status variable.

摘要： A method for firing a detonator in a chain of switch assemblies includes a step of lowering the chain of switch assemblies into a wellbore; a step of powering-up a switch assembly of the chain of switch assemblies; a step of independently entering through a set of states during which the switch assembly interacts with a downstream switch assembly and determines a status of one or more elements associated with the switch assembly; and a step of firing a detonator electrically connected to the switch assembly or entering a sleeping state.
