METHOD OF AUTOMATED OIL WELL PUMP CONTROL AND AN AUTOMATED WELL PUMP CONTROL SYSTEM

摘要

A method of automated oil well pump control. A first step involves preventin g flow in a flow line carrying produced fluids from an oil well while continuing to operate a pump pumping produced fluids from the oil well. A second step involves monitoring pressure in the flow line between the pump and the valve over a pre-selected time interval t o establish a pressure profile. A third step involves speeding up the pump and monitoring any change in the pressure profile. When the pressure profile is characterized by a rise i n pressure indicating that the pump speed has not yet exceeded well production, further increasing the speed of the pump. When the pressure profile shows an intermittent rise in pressure indicating that the pump speed is exceeding well production, deceasing the speed of the pump.
