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 downhole tool for sealing a well includes a push ring, a first slip ring located adjacent to the push ring, a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts, and a sealing element located adjacent to the first wedge and configured to seal the well. An upstream end of the first slip ring and a downstream end of the push ring form a wavy interface when in contact. The wavy interface locks the first slip ring relative to the push ring to prevent a rotation of the first slip ring relative to the push ring.

摘要： A centralizing device is configured to centralize/decentralize an associated tool in a well. The centralizing device includes a body that extends along a longitudinal axis X, the body having a bore that extends from one end to another end of the body; a first piston shaped as a cylinder and provided around a central portion of the body; a second piston shaped as a cylinder and provided around the central portion of the body; a bridge provided around the central portion of the body, between the first and second pistons; and a pair of arms, each arm being attached with one end to a corresponding one of the first and second pistons and with another end to each other. The second piston, the bridge, and the central portion of the body define a sealed chamber, which is sealed from the ambient.

摘要： An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate may include a base with first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. The endplate may include a carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

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 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 perforating gun for making perforations in a well, the perforating gun including a carrier extending along a longitudinal axis X and having a bore; a tube extending along the longitudinal axis X and having a radius smaller than a radius of the carrier so that the tube slides inside the bore of the carrier; a shaped charge placed inside the tube and configured to make a hole through the carrier; and a scallop formed in a body of the carrier, corresponding to a location of the shaped charge along the longitudinal axis X. The scallop has a side surface that makes an angle α with the longitudinal axis X, and the angle α is different from 90 degrees.
