Estudo e Implementação de Técnicas e Controle Aplicado ao Método de Elevação de Bombeio por Cavidades Progressivas

Abstract

In the oil industry, the search for efficiency and better performance of its applications is continuous. In Brazil, the use of Progressive Cavity Pumping (PCP) started in 1982 in the Fazenda Belém field, located in Ceará, and has been constantly evolving over the years. Then, the monitoring of producer wells, equipped by the PCP system, are performed through Sonolog records, being the sensor responsible for recording the fluid level. However, sensor installation and maintenance costs increase the total cost of the pumping system and sensor replacement or repair may require that pump operations be suspended. The fluid level contained in the ring represents an important variable to control, because according to Peterson (2014) from this parameter can protect the pump from damage, optimize pump operation, increase pump efficiency and/or increase production. Therefore, this study proposes a new control strategy, in which a control tool was developed to control the fluid level in the annulus so that with this application, it aims to alleviate the needs of using recording equipment control the fluid level to avoid pump data and improvements in production and operation.
