MULTIPHASE FLOW MEASURING DEVICE, MULTIPHASE FLOW MEASUREMENT METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To grasp the volume flow rate per component of a multiphase flow in real time by a simple configuration.;SOLUTION: Provided is a multiphase flow measuring device characterized by comprising: a measured value acquisition unit for acquiring at least a mass flow measured value and density measured value from a Coriolis flowmeter that measures a measurement object fluid that includes oil and accompanying water from a petroleum production well, and the temperature measured value of a temperature sensor that measures the temperature of the measurement object fluid; and a volume flow rate calculation unit for calculating a gas volume flow rate and a liquid-phase volume flow rate on the basis of the mass flow and density measured values from the measured value acquisition unit, and calculating the volume flow rate of each of the oil and the accompanying water on the basis of the temperature measured value acquired from the measured value acquisition unit.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
