METHOD FOR ESTIMATING THERMODYNAMIC EQUILIBRIUM OF A GAS-LIQUID MIXTURE DURING FILTRATION EXPERIMENTS

摘要

A gas phase and a liquid phase with a specified volumetric ratio of phases in a flow and with specified flow rates are injected into a multiphase separator. During the injection gas and liquid phase volumes in the separator are determined and accumulation rates of each phase in the separator are calculated. A thermodynamic equilibrium is estimated based on a discrepancy between the phase injection rates and the calculated phase accumulation rates.

1. A method for estimating thermodynamic equilibrium of a gas-liquid mixture during a filtration experiment, comprising:
injecting at least once a gas phase and a liquid phase with a specified volumetric ratio of phases in a flow and specified flow rates into a multiphase separator, determining gas and liquid phase volumes in the separator during the injection, calculating an accumulation rate of each phase in the separator, and calculating a discrepancy between phase injection rates and the calculated phase accumulation rates, based on which the thermodynamic equilibrium is estimated.
