Abstract

The present inventions relate to the petroleum extraction industry, more specifically to the determination of phase flow rates in multiphase fluids in industrial pipes and in the transport of petroleum products along main pipelines. The inventions facilitate more accurate measurement of the overall flow rate of non-stationary multiphase streams and the flow rates of individual phases while improving reliability and operational safety. The method proposed involves the creation of a thermal pulse, recording of the said pulse's amplitude-time characteristics and processing of the results obtained. To that end, preliminary assessement of the type of fluid under investigation is undertaken on the basis of its electrical conductivity; creation of the thermal pulse depends on the type of fluid, the amplitude-time characteristics are determined at at least two points separated by a fixed interval, while the dielectric permittivity of the fluid under investigation is also determined. The proposed device comprises a pulse heat source mounted inside a thermally insulated pipe (2) and temperature sensors (8, 9, 10) arranged above and below the heat source. A dielectric permittivity gauge (11) and a pressure gauge (3) are mounted between the upper temperature gauges. Information on the physical parameters of the multiphase fluid are fed by the central processor module (19) to a central computer which applies a specific program to determine the electrical characteristics of the multiphase fluid. The heat source for heating the dielectric liquid is in the form of a helix whose temperature is kept at a level below the spontaneous combustion temperature of hydrocarbon gases.

Description

The device is suitable for use in many applications and is equipped with a liquid outlet and is suitable for its use.

Area of technology

The invention is unavailable, but it is thought to be simpler, and more than that, there are a few differences in the process of consumption of a large amount of industrial fluid.

Pre-privatization level

The method of sharing the caddy phase has been known.

This means that there is only one separation of the number of points, the error is: phase in progress, the loss of service is possible due to: loss of operation :: Is the method also known to have changed? multi-purpose liquid flow, based on a change in the general process flow, the use of a gamma-detectors
