INTEGRATED DOWNHOLE SYSTEM WITH PLURAL TELEMETRY SUBSYSTEMS

摘要

A downhole system has a plurality of telemetry systems and a control system configured to obtain information from one or more sensors and transmit that information on one or more of the plurality of telemetry systems. The configuration of a controller may be changed so as to change which information is transmitted on a given telemetry system and how the information is to be transmitted on the given telemetry system.

1. A downhole system comprising:
a plurality of telemetry subsystems, a control system comprising a plurality of telemetry controllers, each telemetry controller associated and in communication with at least one telemetry subsystem of the plurality of telemetry subsystems, a bus, each telemetry controller of the plurality of telemetry controllers being in communication with each other telemetry controller of the plurality of telemetry controllers via the bus, and one or more sensors in communication with the plurality of telemetry controllers, wherein: a first telemetry controller of the plurality of telemetry controllers is associated with a first telemetry subsystem of the plurality of telemetry subsystems and is operable to obtain first sensor information from a first set of the one or more sensors and to transmit the first sensor information on the first telemetry subsystem; and a second telemetry controller of the plurality of telemetry controllers is associated with a second telemetry subsystem of the plurality of telemetry subsystems and is operable independently of the first telemetry controller to obtain second sensor information from a second set of the one or more sensors and to transmit the second sensor information on the second telemetry subsystem.
