Power sensor implementation of the Well Analyzer for the balancing of air balance rod pumping units

Abstract

It was developed a software that allows to achieve a balancing properly balanced air units in the rod pumping used in ECOPETROL, by implementing the power sensor Well Analyzer team. This sensor is a useful tool which allows an accurate measurement and more reliable than the currently tool used and it allows us to make current analysis of the motor in order to determine the range in which it must have the cylinder pressure to balance the unit. It took several field tests where current measurements were made by varying the cylinder pressure to achieve an approximation among proportion and specifically the relationship between cylinder pressure and the flow of the power unit in the rod pumping, which facilitates us the balancing process. Software was developed in Visual Studio and it was programmed in C# language. It was built owing to main libraries that allow for generating and finding mathematical functions required in the outcomes; we were able to create a user-friendly functional software, which has sequence for a proper balancing step integrating several methods that allow to have a better criterion at balancing the units. Finally, it carries out proofs and validations to observe the efficiency of the software.
