DEVELOPMENT OF A MULTIPHASE FLOW MIXER DEVICE FOR PETROLEUM INDUSTRY
Artigo Completo :
The use of secondary recovery methods for oil wells has become a common practice in the petroleum industry in order to increase production and ensure oil flow to the surface. However, the technological challenges faced, especially offshore, hamper oil rising and open up a range of opportunities for the development of new technologies and enhancement of existing ones. One of the main methods used in artificial lift is the Electrical Submersible Pump (ESP), which has presented problems in gassy well due to electric current fluctuations and gas lock occurrence in the system. The present work proposes the development of a device capable of reducing the negative impact of the large amount of gas mixed with oil in ESP systems by homogenizing the phases upstream the pump. Additionally, the equipment also seems promising in multiphase flow measurement thanks to its ability of reducing the influence of flow regimes along the measurement. CFD multiphase flow simulation was accomplished in commercial software to evaluate its performance in mixtures with high concentration of gas. The simulations results suggest a significant reduction of the gas fraction downstream the equipment to less than 20% for more than 70% of gas at the entry.
