APPARATUS FOR ANALYSIS AND CONTROL OF A RECIPROCATING PUMP SYSTEM BY DETERMINATION OF A PUMP CARD

摘要

An instrumentation system for assessing operation of are-ciprocating pump system which produces hydrocarbons from anon- vertical or a vertical wellbore. The instrumentation system periodicallypro-duces a downhole pump card as a function of a directly or indirectlymea-sured surface card and a friction law function from a wave equation whichdescribes the linear vibrations in a long slender rod. A control signal orcommand signal is generated based on characteristics of the downholepump card for controlling the pumping system. It also generates a pumpand well analysis report that is useful for a pump operation anddetermina-tion of its condition.
