Methods and means of diagnostics for deep-pump equipment of oil wells
For diagnosing a technical state of deeply-pump equipment for oil wells a position-duration-pulse algorithm to analyse amplication signal is suggested. The algorithm allows to simplify a procedure and to raise the reliabilty of diagnosing. With a wiew to provide the reliabilty of diagnosing the hybrid system containing additional expert estimations is used.
