RESUMO:
The Sucker-Rod Pump (SRP) system is the most used artificial lift method in oil
wells in Brazil and in the world. This method stands out for its simplicity, low
cost in investments and maintenance, can be operated in a large range of flowrates
and possibility to operate with fluids of different compositions and viscosities.
However, the Sucker-Rod Pumping Units, as well as all mechanical equipment, require
periodic maintenance, whether corrective or preventive. Two important procedures
commonly made at the SRP Units are the adjustment for counterbalancing the pumping
unit and the adjustment of the polished rod stroke length. Performing these
procedures require stopping the production of the well and are made manually by a
team that is moved to the place where the pumping unit is located. In this context,
Petrobras in partnership with UFRN and other companies developed a new type of
pumping unit, called Smart Sucker-Rod Pump (SSRP), which is capable to
counterbalancing the unit and adjust the polished rod stroke length without the need
of a team to move to the field. Thus, benefiting from the advantages of the SSRP,
this work proposes to develop a strategy to automatically control the Smart
Sucker-Rod Pump. The development of this strategy aims to ensure that the equipment
both operates under proper conditions and within its safety limits (previously set
by the operator), as well as to optimize the well production. In order to validate
the control strategy developed for the SSRP, laboratory simulations were performed
using virtual wells. It was observed that the developing strategy reached the
proposed goals for which it was developed, that is, keep the parameters of the SSRP
within the limits set by the operator and optimize the production flowrate.
