Description
Technical field
Device is determined the present invention relates to multiphase flow, is that a kind of multiphase flow phase fraction determines device list source dual intensity specifically
Gamma and x-ray source storehouse.
Background technology
Since 1990's, more and more not divergence type multi-phase flowmeter to start progressively to substitute tradition huge
Separator, not its conventional basic fundamental route of divergence type multi-phase flowmeter be exactly measure total flow (or flow velocity) and it is each it is single-phase (it is oily,
Gas and water) phase fraction.Common phase fraction measurement method has gamma ray method, ultrasonic method, electric capacity conductance method, microwave method, differential pressure close
Spend the means such as meter method.
Compared with other measuring methods, multiple level gamma ray absorption technique has original advantage.Multiple level gamma ray
Absorption process is a kind of contactless multiphase flow measurement technology, and heterogeneous fluid can be measured simultaneously using the ray of two energy levels
Moisture content and void fraction, without the method for other auxiliary.Because the absorption of gamma ray occurs on an atomic scale
Interaction, therefore, measurement are not influenceed by flow pattern fluidised form and emulsification of crude oil etc..And Non-radioactive methods are generally used for moisture content
Measurement, if to obtain void fraction, it is necessary to obtain (as close in obtained fluid-mixing using gamma density meter by other means
Degree, recycle specific density method obtain void fraction), and measurement process suffer from the continuous phase transformation of profit, temperature change and
The influence of high gassiness operating mode.Therefore, gamma ray absorption technique be that a kind of measurement range is wide, adaptability for working condition is good, measurement accuracy is high,
