TELEMETRY OPERATED SETTING TOOL

摘要

A setting tool for hanging a tubular string includes: a mandrel having an upper portion and a lower portion for extending into the tubular string; a housing connected to the mandrel upper portion; and a bonnet. The bonnet is: for receiving an upper end of the tubular string, disposed along the mandrel, and linked to the housing. The setting tool further includes: an actuator for stroking the bonnet relative to the mandrel and the housing, thereby setting a hanger of the tubular string; an electronics package in communication with the actuator for operating the actuator in response to receiving a command signal; and a latch. The latch is: connected to the mandrel lower portion, operable between an extended position and a retracted position, for being restrained in the retracted position by being disposed in the tubular string, and extendable by being removed from the tubular string.
