DEVICE FOR ANALYSIS AND CONTROL OVER RECIPROCATING PUMP SYSTEM BY DETERMINATION OF PUMP MAP

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to measurement systems for evaluation of reciprocating pump system operation in production of hydrocarbons from vertical well or out of plumb well. This measurement system generates at regular intervals the pump deep map as the function of directly or indirectly measured surface map and function of friction law derived from wave equation describing the linear oscillations in long thin pump rod. Control signal or instruction signal is generated on the basis of pump deep map characteristic for control over pump system. Said system generates also the report on pump and well analysis used for control over pump for determination of its operating conditions.EFFECT: perfected controller to define deep pump map for inclined well according to the surface measurements used to control over pump rod operation.13 cl, 14 dwg
