Systems and Methods for Real-Time Monitoring of Downhole Pump Conditions

摘要

Systems and methods for improved monitoring of downhole pump conditions may provide real-time monitoring, high accuracy, and low noise when monitoring downhole pump conditions. Systems for monitoring pump conditions may be coupled to any suitable sucker rod pump, and may gather desired data from the pump. The desired data may be gathered at several points-in-time during a pump stroke to provide real-time monitoring. A wave equation corresponding to the behavior of the downhole pump may be solved when the desired data is received to provide real-time monitor. In some embodiments, the wave equation may be solved by separating it into static and dynamic solutions. In some embodiments, the dynamic solution of the wave equation may be solved utilizing an integral-based method.
