A simple algorithm is presented for the determination of the counterweight adjustment required to modify the peak torque or the power use.The results of accurately monitored field tests for a variety of beam pumps and well depths are presented in detail. The measurements indicate that unit balancing based on instantaneous power, yields results similar to those obtained from torque derived from dynamometer measurements using a horseshoe type load transducer. The ease of installation of the power probes compared to installation of the dynamometer makes this the preferred method for most beam pumping systems powered by electrical motors.IntroductionPumping unit counterbalancing has always been an integral part of those field operations designed to reduce operating costs. Most commonly counterbalance adjustment has been undertaken using an indicating ammeter to monitor the peak values of motor current during the upstroke and downstroke. Adjustment of the counterweights is typically a tedious trial and error procedure that often does not result in an improved mode of operation. Problems arise especially if the unit is significantly out of balance. In certain instances, the peak current indications of a common ammeter can be confusing due to the presence of a large generating current which cannot be distinguished from current peaks corresponding to motor demand.Alternative methods involving calculation of torque curves from dynamometer measurements have become more common with the advent of PC software that performs the torque analysis and gives recommendations regarding changes in counterweight position required to achieve a balanced condition. Nevertheless routine monitoring and adjustment of counterweights is still considered too time consuming and costly.P. 835 Keywords: counterbalance, society of petroleum engineers, adjustment, counterbalance effect, generation credit, efficiency, sensor, correspond, instantaneous power, beam pumping Subjects: Artificial Lift Systems, Beam and related pumping techniques This content is only available via PDF. 1995.
