DOWNHOLE STEAM GENERATOR CONTROL SYSTEM

摘要

A control system for controlling the operation of a Downhole Steam Generator (DHSG) system includes a cascade control strategy for control of individual final control elements in communication with a local well master controller. The final control elements may control fuel, oxidant, feedwater, and/or carbon dioxide flow to the downhole steam generator. The local well master controller may monitor and adjust the flows to the DHSG to control the operating performance of the DHSG.

1. A control system, comprising:
a local well master controller; a downhole steam generator incorporating a plurality of sensors for measuring operational characteristics of the downhole steam generator and communicating the measured operational characteristics to the local well master controller; and a plurality of flow control loops for controlling fluid flow to the downhole steam generator, wherein the local well master controller is configured to adjust individual flow control setpoints to set various fluid flows to the downhole steam generator to obtain a predetermined injection rate and steam quality.
