Article presents an overview of studies of the gas bubbles interaction processes in the composition of water-gas mixtures. Data are given on theories that indirectly indicate the nature of the phenomenon of coalescence, or its suppression. It has been established that there are rational ranges of parameter values at which coalescence suppression is observed, however, when some critical values of these parameters are exceeded, the coalescence suppression regime breaks down. The experimental studies of the gas flow rate effect, passed in the bubbles flow form through a column with liquid, at various pressures and salinity of the liquid showed that an increase in the maximum gas flow rate with suppressed coalescence is observed in a certain range of salinity (with increasing pressure). However, further with an increase in salinity, the maximum the gas flow rate remains constant, after which the regime breaks. The addition of foaming surfactants increases the maximum gas flow rate. At the same time, a study of multistage centrifugal pump characteristics showed that the addition of surfactants improves the performance of the pump up to a certain concentration, with an increase in this concentration, the performance improves slightly. A further direction of studying the technology of creating stable water-gas mixtures is also formulated.
