Embodiment
A kind of positive displacement multi-phase flowmeter, including measurement cylinder 1, upper and lower displacement sensors A 2, B3, three-way diverter valve A4,
The He of piston 6 is provided with B5, piston 6, plug in sensor 7, pressure sensor 8, control cabinet 9, reversing arrangement 10, measurement cylinder 1
Plug in sensor 7, measurement cylinder 1 is provided with upper inlet C, lower inlet D, upper outlet E, lower outlet F, and inlet A passes through threeway
Reversal valve A4 connection upper inlet C and lower inlet D, liquid outlet B pass through three-way diverter valve B5 connection upper outlet E and lower outlet F, threeway
Reversal valve A4, B5 connect reversing arrangement 10, and measurement cylinder 1 outside upper and lower ends are provided with upper and lower displacement sensors A 2, B3, measuring cylinder
The middle part of body 1 is provided with pressure sensor 8, upper and lower displacement sensors A 2, B3, plug in sensor 7, the connection control of pressure sensor 8
Case 9, three-way diverter valve A4, B5 connection control cabinet 9.Measurement cylinder 1 provides measuring container, the switching of the moment of reversing arrangement 10 for metering
The flow direction of multiphase medium.Upper and lower displacement sensors A 2, B3, plug in sensor 7, pressure sensor 8, real-time output medium
Run location, quantity.Intelligent control box 9, gathers sensor output data in real time, carries out computing, and pass through communication module, nothing
The local expansion equipment of line transmission connection, to many mouthfuls of oil well output Systems.The air-liquid height of fluid media (medium) is passed by plug-in type
What sensor 7 was obtained, fluid media (medium) air-liquid volume is counted by intelligent control box 9
Measuring principle explanation：
The present invention is once measured by the volume to each jig frequency air-liquid, calculates cumulative automatically by control cabinet 9
Complete.
Air-liquid mixture from oil well out enters cylinder 1 through connecting tube from inlet A by upper inlet C, promotes piston
6, which go downwards to medium in the bottom of cylinder 1, cylinder 1, exports F under cylinder and returns to oil field oil transportation to three-way diverter valve B5 by connecting tube
In main pipeline, gas liquid level h1, h2 is perceived by plug in sensor 7 into the gas-liquid in cylinder 1 and transferred data to
Control cabinet 9, volume is calculated by control cabinet 9, and completion is once measured；Instantly displacement transducer B3 detects piston 6 and goes downwards to cylinder
The bottom of body 1, outputs signal to control cabinet 9, and control cabinet 9 sends instruction, and three-way diverter valve A4, B5 commutate simultaneously, and medium (mix by gas-liquid
Compound) enter from inlet A, entered by connecting pipe by the bottom lower inlet D of cylinder 1 and promote piston 6 up, it is former in cylinder 1
Some media, from the upper outlet E of cylinder 1 returns to oil field oil transportation main pipeline by connecting tube to three-way diverter valve B5, complete second
The metering of jig frequency.And so on, acquired data are added up automatically in control cabinet, produced in real time so as to obtain every mouthful of well
Air-liquid amount, it is therefore an objective to provide foundation for oil field energy saving control, meter production.
Reversing arrangement 10 provides compressed air for three-way diverter valve A4, B5 and commutated as safe power.
As shown in Fig. 2 measuring h1 values by plug in sensor 7, and correspondence moment pressure p is measured by pressure sensor
Value, you can obtain bulking value.
V1=h1SP
V2=h2S
In formula, V1 is gas volume, and V2 is liquid volume, and h1 is gas height in cylinder, and h2 is liquid height in cylinder,
S is cylinder floor space, and P is pressure.
