The relevance of the research follows from the need to assess the dynamic level of liquid in oil producing and water wells with the necessary frequency, which can be provided as one of the functions of an intelligent well. The aim of the research is to search for alternative methods for determining the liquid level in the annulus of wells without involving personnel in the well zone. Objects: oil producing wells equipped with pressure sensors, generators and receivers of acoustic waves and secondary instruments for transmitting information to the workplaces of the personnel of the enterprise. Methods: based on the well-known laws of physical hydrodynamics and methods of mathematical statistics. Results. The soundometric method for determining the dynamic liquid level in the annulus of a well has an error in measurements in existing oil wells due to the inconstancy of the composition of associated petroleum gas in time and in the depth of the tubing at a fixed point in time.
