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 a reciprocating pump system which produces hydrocarbons from a non- vertical or a vertical wellbore. The instrumentation system periodically produces a downhole pump card as a function of a directly or indirectly measured surface card and a friction law function from a wave equation which describes the linear vibrations in a long slender rod. A control signal or command signal is generated based on characteristics of the downhole pump card for controlling the pumping system. It also generates a pump and well analysis report that is useful for a pump operation and determination of its condition.
