FIELD: oil and gas industry.
SUBSTANCE: system includes flow rate meters arranged on the well products' pipes as well as the wells' flow direction selection unit. According to the invention, system includes first-group flow rate meters in number equal to the number of controllable wells which are located on outlet piping of the wells' products, and have the possibility to constantly make measurements of these wells. At least one second-group flow rate meter is provided, and it has the possibility to make the well productivity cyclic measurements during the period determined in advance, until any first-group flow rate meter fixes changes in well productivity, which are bigger than previously given limit. There is wells' flow direction selection unit, to inputs of which wells' products pipelines are connected. The first output of selection unit is connected to main pipeline. The second output is connected to input of second-group flow rate meter the output of which is connected to main pipeline. In this case the system includes additional control device which is connected with flow rate meters' outputs and flow direction selection unit, and is provided with the possibility of measurement data acquisition with first-group flow rate meters, measurement data storage, measurement data acquisition and storage with second-group flow rate meters, and flow direction selection unit control when recording, by means of any first-group flow rate meter, wells' products crossing the given limit.
EFFECT: increasing the reliability and informativity of system measurements resulted from response speed increase to the change in the well's operating parameters.
