The relevance of the use of surfactant solutions in oil production is considered. It is indicated that physicochemical methods of influence on productive strata with the use of surfactants are used to increase oil production from subsoil. To evaluate the effectiveness of the use of surfactants measure the surface tension at the boundary of the solution of surfactant - gas and the interfacial tension at the boundary of the solution of surfactant - oil. An analysis of existing methods for measuring surface tension. Based on the analysis, it is shown that there is a significant variety of methods for determining the surface tension of liquids, which can be grouped as follows: methods for determining the surface tension of liquids, based on the study of the profiles of the menisci of the fluid of a fixed shape; methods of two menisci; methods of extreme values of parameters; methods that use menisci on the verge of stability; special dynamic methods; methods that use the field of rotation. It is stated that all methods of measuring surface tension are indirect. The informative parameters which control or measure for definition of a surface tension by the considered methods are listed. The methods that have become widespread are indicated: the Wilhelm plate method; methods of lying, hanging and rotating drop; the method of the pressed bubble, the method of counting drops, the method of separation of the ring, the method of measuring the maximum pressure in the gas bubble. The principle of construction of devices that implement methods of measuring surface tension is considered, the peculiarities of their functioning are indicated. The comparative analysis of methods and devices for measurement of surface and interfacial tension of liquids is carried out. Based on this analysis, a choice of methods for measuring the interfacial tension of surfactant solutions was made: methods of lying or hanging drops, drop volume and rotating drop.
