METHOD FOR INTERPRETING DATA MEASURED IN A HYDROCARBON WELL IN PRODUCTION

摘要

The invention concerns a method for calculating the relative volumetric flow-rates of at least one of the phases of a multiphase effluent flowing in awell, said method comprising a first step of acquiring local volumetricfractions and/or velocities of said phases across a section of the well at acertain depth. The method further comprises: - corrections of said localvolumetric fraction and/or velocity measurements in order to make themconsistent with each other and/or with the effluent flow conditions; -selection of a suitable flow model mathematically representing the effluentflow; - interpolation of said local volumetric fraction measurements and/orsaid local velocity measurements by the selected flow model in order to obtaina volumetric fraction profile and/or a velocity profile for at least one phaseof the effluent across said section of the well at said depth.- calculation ofthe relative volumetric flow-rates of said at least one phase by integrationof said volumetric fraction and/or velocity profiles over said section of thewell at said depth.
