Este m?todo utiliza um ?mbolo mec?nico para auxiliar a subida do ?leo do fundo do po?o at? a superf?cie, atrav?s do fechamento e abertura do po?o com intervalo de tempo distintos. O plunger lift possui algumas etapas que, quando conclu?das, completam um ciclo. Foi desenvolvido um simulador em Java R com o modelo matem?tico implementado no projeto AUTOPOC, desenvolvido no Laborat?rio de Automa??o em Petr?leo, na linguagem C++. Foram implementados dois tipos de controle liga-desliga para este m?todo: controle por temporiza??o e controle por press?o de revestimento. Por fim, resultados s?o obtidos com o simulador, os quais s?o comparados para uma an?lise detalhada e conclus?es acerca do desempenho dos controladores implementados. === 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 Laborat?rio de Automa??o em Petr?leo, 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.
