High rates of oil production require finding ways to improve the efficiency of wells. The analysis shows that in oil and gas condensate fields, marginal and bottom formation waters often break through to the bottom of the well. Wells are gradually flooded, which leads to the formation of oil emulsions. The motion of emulsion unstable systems in the field has a number of important features, the knowledge of which is necessary for the correct solution of the problem of increasing the efficiency of collecting oil, gas and water.
