Simulador computacional do método de elevação artificial Plunger Lift e implementação de controladores para estudo comparativo

Abstract

This work aboard the artificial lift method named plunger lift, that is used in wells with low reservoir pressure. This method uses a mechanical plunger to help the oil lift from the bottom of the well to the surface through the well, closing and opening with different time interval. The plunger lift has some stages that, when concluded, complete a cycle. It was developed a simulator in Java R with mathematical model implemented in the AUTOPOC, project developed at Laboratório de Automação em Petróleo, in C++ language. It were implemented two types of on-off controls for this method: time control and control by casing pressure. Finally, results are obtained with the simulator, what are compared for detailed analysis and take conclusions about the performance of the implemented controllers.
