Resumen: The downhole pump of artificial lift method sucker rod pumping is a component that
has the highest number of failures when working with heavy oils, due to this fact, this
work employs a numerical analysis of the fluid inside this equipment. The analysis
focused primarily understanding the behavior of the standing valve, one of the most
important components of the pump, and its influence on the flow inside the pump. The
analysis parameters are fill rate of the shirt, Pressure Drop, difficulties in closing and
predict the occurrence of pump off. The study uses a typical pump system geometry,
which was built using Inventor ® 3D CAD the real 3D geometric conditions. The Ansys
Fluent version 14.5 software was used to solve the coupled equation system of fluid
flow and motion of the standing valve, considered rigid. The final computational model
allowed to judge if the type of bottom pump chosen is adequate and predict the
occurrence of pump off, in order to achieve a longer service life of the downhole pump
and evaluate the best performance upon various operating conditions. As a final
product, was obtained a tool for the analysis of standing valves pumps background in
order to avoid premature failure.
