Resumo
A estimulação ultrassônica é uma técnica recém descoberta e revolucionária. Tem como propósito estimular os poços petrolíferos para fomentar a extração de petróleo. O objetivo deste trabalho é estudar o detalhamento técnico de bancadas experimentais já utilizadas para analisar a eficiência e a eficácia de extração de petróleo através de propagação de ondas ultrassônicas. No trabalho o enfoque foi em dois experimentos, são eles o experimento de gota pendente e o experimento de embebição espontânea, onde foram estudados e analisados o comportamento dos fluídos com e sem a presença da estimulação ultrassônica. Esta estimulação é capaz de alterar as propriedades dos fluídos como aumento da temperatura, diminuição da viscosidade e diminuição da tensão interfacial e superficial, além de alterar também as propriedades da rocha que contém o petróleo como permeabilidade, tamanho do grão, geometria do poro, molhabilidade, heterogeneidade e condições de contorno. Através destas alterações provocadas pela técnica de estimulação acústica, é possível ter um aumento significativo na recuperação de petróleo.
The ultrasonic wave stimulation is a newly discovered and revolutionary technique. The purpose of it is to stimulate oil wells to enhance oil extraction. The objective of this work is to study the technical details of experimental benches already used to analyze the efficiency and effectiveness of oil extraction through the propagation of ultrasonic waves. The focus of this work was on two experiments, which was the drop experiment and the spontaneous imbibition experiment. The experiments explored the behavior of fluids with and without the presence of ultrasonic stimulation was studied and analyzed. This technique is able to change the properties of the fluids, such as increasing the temperature, decreasing the viscosity and decreasing the interfacial and surface tension, besides also changing the properties of the rock that contains the oil, such as permeability, grain size, pore geometry, wettability, heterogeneity and boundary conditions. With these property changes, it is possible to have a significant increase in oil recovery.
