摘要
A control and monitoring system for chemical system for chemical treatment of an oilfield well is presented. In accordance with the present invention, a chemical injection monitoring and control system includes the placement of one or more sensors downhole in a producing zone for measuring the chemical properties of the produced fluid as well as for measuring other downhold parameters of interest. These sensors are preferably fiber optic based and provide a high temperature, reliable, and relatively inexpensive indicator of the desired chemical parameter. Surface and/or downhold controllers receive input from the several downhole sensors; and in response thereto, control the injection of chemicals into a wellbore and/or surface treatment system. By the sensors communicating with both the surface and/or downhole controllers, the effectiveness of the downhole or surface treatment system is monitored in real-time and based on the sensed information, the controllers will initiate some change in the manner, amount, or type of the chemical being injected.
