| 摘要 |
An automated control system for an oil well pump, comprising a pump speed sensor, a pump torque sensor, a gas pressure sensor, sensors adapted to collectively determine proportions of water and oil in liquid production flow, and a control processor adapted to receive inputs from the pump speed sensor, the pump torque sensor, the gas pressure sensor and the relative proportions of water and oil in liquid production flow. The control processor is programmed to alter pump speed to maximize the relative proportion of oil to water.
