Power management system for downhole control system in a well and method of using same

摘要

A downhole power management technique for a downhole well control system maximizes the number of downhole devices which require electrical power. In accordance with this technique, downhole devices which require power and are addressable will be at a low power consumption state (e.g., sleep or dormant mode). When requested by a downhole or surface controller, the downhole device will turn itself on to an active mode and perform its intended function or task (such as transmitting data, acquiring data, actuating a tool or the like). Preferably, only one downhole device is in its active mode at any one time. As a result of this power management technique, the power requirement downhole will be relatively low and substantially constant regardless of the number of downhole devices requiring power.
