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 sheave wheel includes a housing; a wheel attached to the housing and configured to rotate relative to the housing; a depth and tension measurement system attached to the housing and configured to measure a parameter associated with the wheel; and a local control system attached to the housing and configured to exchange information associated with the measured parameter in a wireless manner with a ground control system.

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, a voltage measuring unit configured to locally measure a voltage (V) at the switch assembly after receiving the fire command to activate the detonator, 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 and after measuring the voltage (V), based on whether or not the measured voltage (V) at the switch assembly is larger than a threshold value.

摘要： A downhole system includes a controller located at the surface, a gun string located in a wellbore, the gun string including plural gun assemblies, a thru-line connecting the controller to the gun string, and a detonator block attached to a given gun assembly. The detonator block includes an addressable switch assembly. The gun assembly includes an end plate mechanism that electrically connects to the detonator block. The detonator block has at least one spring-loaded contact connected to the thru-line and the end plate mechanism includes a round electrical contact made as a printed circuit board, and the spring-loaded contact touches the printed circuit board.
