Annotation:
The study of gas-stabilizing devices operation (gas separators, dispersants, multi-phase axial pumps) is quite an urgent issue. To date, this type of equipment is widely used as a part of electric blade pump installations. The use of dispersing devices is caused by certain operating conditions, in which there is no possibility of the gas phase separation into the space between the tubing column and the production column. For example, such a need arises in the presence of a downhole sealing device (packer) or in flooded wells. For a more detailed study of gas-stabilizing devices, it is necessary to understand at what values of the free gas content at the inlet this device is capable of creating a positive pressure drop. Such studies can be carried out both with the help of numerical experiments and with the help of a full-scale experiment. This article presents the results of numerical and physical experiments of a conventional 5 size dispersant. The dispersant layout is manufactured with the help of additive technologies. According to the results of the study, graphical dependences are built: pressure, pressure drop from the supply of the dispersant. The results of numerical and bench tests have shown good convergence, thus indicating the fact that numerical experiments allow the creation of dispersants new designs and modifications of the existing ones.
