FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to well pumps, in particular, to a method and apparatus for determining production of downhole pumps. Method includes measuring an amount of liquid produced from a well by a pumping unit during a predetermined time period. For this, first areas of first pump cards are determined during the predetermined time period. First areas are summed. Leakage proportionality constant of a downhole pump of the pumping unit is determined based on the amount of liquid produced and the summed first areas. Second areas of the second pump cards are determined while continuously operating the pumping unit over a second predetermined time period. Net fluid produced during the second predetermined time period is determined based on the leakage proportionality constant and the second areas.
EFFECT: improved accuracy in determining production of said pumps.
