Method and System for obtaining a model of composition of produced Fluids using a model of composition of Fluid produced by the Information Analysis of Discharge of a repairman

摘要

The Invention relates to a method for production of an Oil Field, which has at least one installation process and at least one Well site functionally connected to the installation processWhere each Well site has a well penetrating a Subterranean Formation for the extraction of Fluid from an underground Reservoir there.The Method comprises the steps of obtaining a sample of Fluid separator Discharge from a Fluid separator separator, where he receives from the underground Reservoir; the realization of gas chromatography on the Fluid Discharge separatorIn order to obtain the gas molar composition; the realization of the characterization on the Oily Fluid separator Discharge, thus obtaining the density and Molecular Weight Oily Oil; Performing a First Simulation, using the molar Density gaseous composition, Ole OsaThe Molecular Weight of Oil and Gas Oil ratio (GOR) Fluid separator Discharge, in order to obtain a composition simulated Fluid Inlet of the separator, where the first simulation is performed using a Simulator; Performing a Second Simulation, using the composic Simulated ion Fluid Inlet of the separatorTo obtain a composition simulated FLUID OUTLET of the separator, where the second simulation is performed using the Simulator to compare the composition of simulated Fluid separator with a departure of the real Composition of Fluid out of the separatorWhere the real Composition of the FLUID OUTLET of the separator is obtained from the sample; and the Presentation of the composition of simulated Fluid Inlet of the separator, where the difference between the actual composition of Fluid out of the separator and the simulated output Fluid composition Separator is lower than a Threshold Value.
