Previous issue date: 2017-07-10 === Este trabalho aborda o m?todo de eleva??o artificial chamado plunger lift, que ? utilizado
em po?os com baixa press?o de reservat?rio. 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.
