SURFACE CONTROLLED RESERVOIR ANALYSIS AND MANAGEMENT SYSTEM

摘要

A well control system for providing surface control of downhole production tools (38) in a well. The well control system is capable of detecting well conditions and of generating command signals for operating one or more well tools (38). An electric conductor (46) transmits electric signals, and a hydraulic line (44) containing pressurized hydraulic fluid provides the power necessary to operate downhole tools (38). The invention provides a unique system for providing redundant conductors (46A-46F) and redundant hydraulic lines (44A-44F) to the well tool (38) to continue operation if an electric conductor (46) or hydraulic line (44) becomes disabled. The well control tool (38) also permits the selective operation of multiple production zones (32, 34, 36) in a producing well (14).
