Technological operations using aqueous solutions of surface-active substances are mandatory elements of a significant number of well operation and repair technologies. Currently, the results of studies on the use of aqueous solutions of surface-active substances for regulating phase and energy interactions in the processes of drilling wells, discovering productive formations, increasing oil recovery, treating the bottom-hole formation zone of production and injection wells, oil preparation, and the fight against corrosion of underground equipment are known inhibition of organic deposits.

In modern conditions, increasing the effectiveness of the use of aqueous solutions of surfactants to remove organic deposits formed during the operation of wells is becoming relevant.

The paper presents the results of the analysis of the use of aqueous solutions of surfactants in the field facilities of Tatneft Public Joint Stock Company. The conditions of washing are studied from the point of view of the hydrodynamics of the process, in particular, the pressure values at the beginning of washing and at the end of washing. The main factors determining the effectiveness of well flushing have been identified.
