Identification of the Parameters of a Discrete Gas-Lift Process

A time-averaged mathematical model of a discrete gas-lift process is considered. At the first iteration, an analytical expression for the gas-liquid mixture (GLM) at the end of the lift is constructed using a small parameter (the small parameter is taken as the reciprocal of the well depth) and it i...

Summary:A time-averaged mathematical model of a discrete gas-lift process is considered. At the first iteration, an analytical expression for the gas-liquid mixture (GLM) at the end of the lift is constructed using a small parameter (the small parameter is taken as the reciprocal of the well depth) and it is assumed that the hydraulic resistance coefficient has different values in two different parts of the lift. To find the specified coefficient, the least squares method is used. Experimental data are introduced and the objective function, which characterizes the closeness of the physical variables obtained from the model and from these data, is minimized. The final result is presented in the given example and it coincides with the corresponding values found by other methods.
