102505931 A of Chinese patent notification number CN, date of publication are as follows: on June 20th, 2012, it is entitled ' gas-liquid separation and
Oil-water-gas three-phase flow measuring device ' in disclose a kind of gas-liquid separating method, using gas and oil and water density and molecule it is straight
The difference of diameter realizes gas-liquid separation；Density and the small gas of molecular diameter directly flow into the pipe of inlet tube and isolated tube from air inlet duct
In absolutely empty；Density and the big oil of molecular diameter, water liquid are difficult through air inlet duct, but due to the molecular diameter of liquids and gases
All in nanoscale, so-called air inlet duct is the hole (or seam) being machined into, the diameter with molecule far from an order of magnitude,
Therefore this structure is unable to reach effect described in patent.
102767359 A of Chinese patent notification number CN, date of publication are as follows: on November 7th, 2012, entitled ' volume-cumulative formula
Low-yield liquid oil well three-phase flow measuring apparatus ' in disclose a kind of difference by oil gas water in density, realize fluid in afflux
Natural separation in umbrella, due to control gas phase threshold switch pressure difference is smaller and the limitation in space, it is easy to stain by crude oil, husky card with
And the influence of rod-pumped well stroke, lead to switch failure.
102913225 A of Chinese patent notification number CN, date of publication are as follows: on 2 6th, 2013, entitled ' underground multiphase flow
Gas phase separation and measuring device ' disclosed in technology it is similar to 102767359 A of CN, and there are similar technological deficiencies.
103089255 A of Chinese patent application publication No. CN, date of publication are as follows: on May 8th, 2013, entitled ' a kind of complete
Afflux dynamic interface tracing multiphase flow logging instrument ', with the interface level measurement sensor measurement interface of oil and gas and oil-water interfaces to moving down
Dynamic speed calculates the yield of outlet and oil, due to apparatus structure complexity, is limited by space, there is runners, and small, water conservancy diversion joins
The problems such as motivation structure Yi Shaka fails.
For oil well three-phase flow measurement, other than the method used in above-mentioned patent, there are also early stage, the radioactivity of application is low
Energy law, but due to human body there are radiation damage, and it is higher to the stability requirement of air-flow when measurement the problems such as, should
Method has been eliminated in production logging field.
Also, in production profile logging, either two-phase flow measurement or three-phase flow measurement, the measurement of flow are generally adopted
With turbine flowmeter, turbine flowmeter has that Yi Shaka, starting flow be high in use and K value is big etc. by one by material properties affect
Straight insurmountable drawback.
