Abstract

"SISTEMA DE INJEçãO QUìMICA E MONITORAçãO EM LAçO FECHADO PARA OPERAçõES EM CAMPOS DE PETRóLEO". Disponibiliza-se um sistema que monitora, na área de locação de poços, a injeção de aditivos em líquidos de formação recuperados através dos furos do poço e controla o suprimento de tais aditivos a partir de locações remotas. Uma bomba supre o aditivo selecionado a partir de uma fonte na área de locação de poços para dentro do furo do poço, via linha de suprimento apropriada. Um fluxímetro na linha de suprimento mede a taxa de fluxo do aditivo através da linha de suprimento e gera sinais representativos desta taxa de fluxo. Um controlador na área de locação de poços determina a taxa de fluxo a partir dos sinais do fluxímetro e, em resposta aos mesmos, comanda a bomba no sentido de controlar a taxa de fluxo do aditivo para o poço. O controlador da área de locação de poços faz interface com um enlace de comunicação em dois sentidos, e transmite sinais e dados representativos da taxa de fluxo, bem como outros parâmetros para um segundo controlador remoto. O controlador remoto transmite sinais de comando para o controlador na área de locação de poços, cujos sinais são representativos de qualquer mudança desejada na taxa de fluxo. O controlador na área de locação de poços é baseado em microprocessador e pode ser programado na referida área de locação de poços, ou pelo controlador remoto, para regular a taxa de fluxo. O sistema da presente invenção pode ser configurado para múltiplos poços, situação em que cada poço tem um controlador de área de locação de poços em separado, ou um controlador de área de locação de poços em comum.
