The research of gas blisters concentration influence on natural separation factor value
In presented article the proof of gas blisters concentration (or volume gas content) also is the factor essentially influencing on natural gas separation process, especially at reversive liquid current, is visually shown. In article the numerical experiment technology spent with use of diphasic mathematical model of package ANSYS CFX, for an estimation of gas blisters concentration influence in separation zone on a longitudinal pressure gradient, is described. Dependences considering influence of volume gas content on pressure gradient value in well punching zone and of hydrodynamic resistance factor are offered. In conclusion of article the analysis of operational well parametres influence (of liquid phase production rate, of through passage section ring channel area, of fluid water cut and of fluid gas factor) on natural separation factor value is resulted. By given analysis results the conclusion has been made, that fluid water cut increase positively promotes natural gas separation process in reversive liquid stream.
