摘要: In a liquid well pumping system which is provided with a downtime between pumpoff cycles, the method of determining the maximum downtime includes running a plurality of tests to determine the relationship between runtime and downtime and determining when the relationship becomes non-linear for at least two consecutive tests. The downtime is selected adjacent the last linear relationship between runtime and downtime for providing a downtime which allows adequate fluid buildup in the well, but not so long a period as to loose well production.

摘要: A method of calibrating a well pumpoff controller by calibrating the controller for determining the average load during a pumping stroke, measuring the actual load and averaging the measured maximum and minimum load during each operational stroke, comparing the average measured load with the calibrated average load and providing an offset to the load measurement to correct the measured load towards the calibrated load.
