Description
Technical field
The utility model belongs to fluid separate measurement technical field, and in particular to detaches meter in real time to a kind of oil gas water three phase
Measure device.
Background technology
Crude oil is typical multiphase flow, including oil, gas and water three-phase material, oil phase refers to the petroleum hydrocarbon phase in produced liquid in oil well,
Gas phase refers to natural gas, lighter hydrocarbons, non-light hydrocarbon gas, and water phase refers to then mineralized water, while also a small amount of solid phase (sand, cured, hydration
Object).There is only a variety of flow patterns in flow process for oil gas water multiphase, and complicated component is changeable, and flow monitoring is difficult.So
And in order to reasonably carry out oil field development, it is necessary to grasp the yield of single port oil well, including the oil production of every mouthful of oil well, water yield
And gas production.Currently, in order to obtain these multidate informations, the way in most oil field is to use satellite-type measuring station mode, is passed through
Manifold switches, every mouthful of oil well of tours of inspection, is separated into oil phase, water phase and gas phase through metering separator, then use each single-phase measurement
Instrument or device obtain the respective content of three components, then remix and are transported to pumping plant and carry out production processing.Used in this method
Metering separator equipment volume is huge, is unable to on-line measurement, to constrain production efficiency significantly.In the 1980s, west
The requirement of the large-scale three separate type metering systems of exploitation multi-phase flowmeter substitution is mainly proposed by company, and is cooperated with each university
The development and exploitation of multi-phase flowmeter are carried out, China also expands the research work of this respect the 1990s.
The online real time measure of three, oil gas water is one of global problem, and especially in laboratory scientific research flow, high temperature is high
The experimental situation of pressure is extremely easy so that emulsion occurs for grease, and emulsification refers to that a kind of liquid is equably divided with atomic droplet
It is dispersed in another immiscible liquid, so that two kinds of liquid that originally cannot be admixed together is mixed together, formed not
Easily layering, more stable mixture.Once emulsion occurs, it will bring great difficulty to water-oil separating.
The method used at present suitable for the oil-gas-water three-phase separation of laboratory scientific research flow has image method, density contrast
Hair, electric-resistivity method, weight method and pressure differential method etc..Image method will be unable to accurate judgement oil-water interfaces and nothing when grease emulsifies
Method works；Density difference is easy to influence grease density when there is gas, so as to cause error；On the one hand electric-resistivity method is easy electrolysis
It generates gas and electrode is caused to judge that failure, another aspect electrode are easy to be covered by greasy dirt and caused to fail；Weight method be easy by
The influence of temperature and it is inaccurate；Pressure differential method refer to control gas/oil and oil/water interface in real time by differential pressure pickup, thus its
Not by emulsify, high temperature, gas are influenced, can efficiently solve more than problem.

Measure the suction control Δ of device 302 P1-2(t)≈ΔP1-2(t=0), the water of suction is the water into device, to realize
To the real-time separate measurement of water；
(3) it when the fluid that fluid inlet 105 enters is only gas, due to the density very little of gas, is pressed caused by gas
Difference variation is 0, and gas automatically flows into gas flowmeter 400, to realize the real-time separate measurement to gas；
(4) when the fluid that fluid inlet 105 enters is oil gas water, height of the pasta in volume weight tube 100 increases, the water surface
Height in volume weight tube 100 also increases, and is equivalent to while occurring (1), (2) and (3) three kinds of situations, both P1(t) > P1(t=
0), Δ P1-2(t)≠ΔP1-2(t=0), metering device 301, second is extracted by gas flowmeter 400, first at this time and extracts meter
It measures device 302 and controls P1(t)≈P1(t=0), Δ P1-2(t)≈ΔP1-2(t=0), the grease amount of extraction is into device
Grease amount, the flow for flowing into gas flowmeter 400 are the tolerance into device, to realize that the real-time separation to oil gas water is counted
Amount.
