摘要:
Methods for measuring the leakage rate of a downhole pump using either measured axial load information from the drive rod string or using measured production data. The invention is for methods of applying the leakage rate to a downhole dynamometer card, for a reciprocating rod pump, for determining well production.
摘要:
The present invention provides highly accurate methods for directly calculating pump fillage which avoid the need and expense of a pump dynamometer card and subsequent calculations.
