DYNAMOMETER TEST
The Well Analyzer is used with dynamometer load
cells to gather dynamometer data which is processed and analyzed to determine the
loading
and performance of the surface unit, rod string, and the downhole
pump.
Two dynamometer load cells are
available. The polished rod transducer is attached to the polished rod below the carrier
bar. Generally, the pumping unit can be operating during the installation of the polished
rod transducer. The horseshoe transducer is a very accurate load cell for performing a
more complete dynamometer analysis including precise measurement of valve loads and
mechanical torque analysis.
The accelerometer built into both dynamometers
provides a compact, convenient and inexpensive technique to determine polished rod
position and surface dynagraph by plotting load versus position. A
downhole pump dynagraph is calculated for determination of pump performance. Traveling and
standing valve tests can be performed. The horseshoe transducer can be used to obtain a
mechanical torque analysis on the gearbox. A permissible load diagram is displayed.
Motor current is acquired and displayed for determination of motor loading and gearbox
balancing. An optional motor power sensor is available.
