In facial canal road in flow process, the measurement of its flow and phase content belongs to typical multiphase flow metering problem." three in the present invention
Phase " refers to associated gas phase, oil phase, aqueous phase.Due to the complexity of Multiphase Flow, the development of oil gas water multiphase gauge have compared with
Big difficulty, it presently, there are the Development Techniques route of a variety of multi-phase flowmeters.
In two-phase flow measurement technology, partition method is still current most reliable and precision highest technology.Such as Chinese patent
ZL200810112558.3, ZL200710046862.8 etc. are as oil gas water three phase piece-rate system, so using tun
Afterwards in the method using single-phase measurement.Because this method is that oil gas water three phase fluid in heterogeneous fluid is separated into single phase gas
After oil and water, then each phase flow rate of single-phase flow flowmeter measurement is used respectively, thus avoid the factors such as variations in flow patterns and flowing instability
Influence to measurement.But in actual multiphase fluid measurements, many fluids can not accomplish sometimes it is cost-effective be kept completely separate, this
Individual multiphase measurement brings many troubles.Consider problem above, domestic and international researcher also uses the technology of being partially separated, such as
United States Patent (USP) US6128962, using the method that is partially separated, separator size is reduced, but be not to be completely separated into whole three-phase flows
Single-phase flow, it have impact on measuring accuracy.Chinese patent ZL98113068.2 also uses a kind of similar shunting split-phase type measurement side
Method, but when the flow very little of the liquid phase in two phase flow or gas phase (low air void or high-moisture percentage), by shunting, from separation
The gas phase or oil phase flow of device outflow are just smaller, can not represent entirety, cause error in dipping big.United States Patent (USP) US5390547 and
US7311001 individually discloses a kind of multiphase flow measuring device, and a kind of piece-rate system is formed in itself merely with heterogeneous fluid pipeline.
The system abandons traditional separator, but uses external cyclonic separation mode, therefore substantially it and traditional partition method
Not tangible difference.In recent years, as the progress that correlative study works, the new technology of multiphase detection continuously emerge, this makes
The performance for obtaining following multi-phase flowmeter is possible to be greatly improved.Such as carried out using using electricity, magnetic or radioactive mode
Line measures phase density, phase content and the phase velocity method of oil gas water three phase, so as to realize that oil gas water three phase measures, such as
ZL201410468193.3 and 200810150257.X etc., but it is big for this flow of oil well produced liquid and phase content fluctuation range
With the occasion of complex flow, the application of prior art still has very big difficulty.
