FIELD: oil-and-gas production.
SUBSTANCE: invention related to oil-and-gas production and meant multiphase fluid for oil and gas composition analysis. Method executed in on - line regime. From the sources flow transported as a mixed flow via single pipeline. In and after the pipeline execute composition measurements, at least on of the mixed flow phases. It is analysed with device, which uses mixed flow fluid probes, the measurement results sent to computing device, which calculates flow form every source with help of separation algorithm that uses measured mixed flow, analysed composition of at least one phase, associated with every source.
EFFECT: distribution of backward flow to well or reservoir reliability increase in oil and/or gas production systems.
