methods and apparatus for determining the operating parameters of a pumping unit for use in wells

摘要

Methods and apparatus for determining the operating parameters of a pumping unit for use in wells are disclosed. An exemplary apparatus includes a housing and a processor positioned in the housing. the processor is to determine a rate at which to operate a motor of a pumping unit to allow a load transmitted on a polished rod of the pumping unit to be within a limit of a reference load or to allow a polished rod speed to be within a limit of a reference speed.
