Resumen
A pilot system was built at the Laboratório de Avaliação de Medição em Petróleo
(LAMP) to evaluate estimation methods of flow distribution in multizone injection wells
by heat transmission models. In this work an automation system was developed with
a sensor structure, actuators and a monitoring software, to control the variables needed
to the process simulation of water injection in the plant built. The follow equipement
were used: flow, level and temperature sensors, and actuators like valves and pumps, all
connected to a programmable logic controller by WEG
R , model: TPW03 60HT-A, that
is able to concentrate the data and communicate with a monitoring system implemented
in Elipse
R SCADA software. This structure acquired data to evaluate the flow estimation
method from temperature measurements throughout the simulated injection tubing.
The flow sensors allowed the comparison of the measured and estimated values with the
mathematical model. Adjustments were made in the original designed structure and the
experiments were repeated in order to reduce the measurement uncertainty obtained in
previous tests.
