2105 taper angle 120o, the conical surface angle 100o of sonic guide body 2103, REFRACTIVE LIQUID 2104 is water.
1, working principle
When device works, supersonic Doppler probe 21 oliquely downward emits ultrasonic wave, and receives back wave, circular hair
The middle part that piezoelectric patches 2101 is located at sound wave emitter 2105 is penetrated, annular reception piezoelectric patches 2102 is located at sound wave emitter 2105
Outside, sound deflection liquid 2104 is filled between sonic guide body 2103 and sound wave emitter 2105, sealing " O " ring is for preventing
REFRACTIVE LIQUID 2104 leaks out.
After the sound wave that transmission piezoelectric piece 2101 generates reaches the surface of emission 2131 of sound wave emitter 5, due to REFRACTIVE LIQUID 2104
With the difference of 2105 acoustic resistance of sound wave emitter, sound wave is reflected in the surface of emission 2131, and the sound wave along Propagation is made to be folded to diameter
To after the sound wave reflected reaches the receiving plane 2132 of sonic guide body 2103, sound wave direction is almost hung down with receiving plane 2132
Directly, sound wave direction does not change, and continues to propagate, and is finally issued by device outer wall 2133, into the space of oil well casing 4.Sound
When wave encounters the oil vacuole or bubble that flow up in water in casing space, Doppler effect occurs, sound wave reflects outside return device
Wall 2133 reaches the reception piezoelectric patches 2102 of annular along the path of transmitted wave, obtains the electric signal comprising fluid flow information.
2, measuring principle
Production pay produces oil, gas and water three-phase simultaneously, and due to the difference of specific gravity of oil, gas and water three-phase, background fills in casing
Full water, oil that production pay flows into casing, gas two-phase are flowed up in the form of foam, since density of gas phase is much smaller than oily phase
Density, bubble phase are greater than slippage velocity of the oil vacuole relative to water for the slippage velocity of water.Measuring device occupy oil well when work
Casing center, as shown in Figure 1, ultrasonic probe oliquely downward issues ultrasonic wave, sound wave encounter the oil vacuole flowed up in water or
When bubble, reflection is generated, back wave is received by probe.
The ultrasonic wave that supersonic Doppler probe issues can indicate are as follows:
u0=A0sin(2πf0t)
Wherein, A0For wave amplitude, f0For frequency.
It can be indicated by the back wave that movement oil vacuole and bubble are reflected back probe are as follows:
U=A1sin(2πf1t)+······+Aisin(2πfit)
Wherein, u is the sound wave summation of different amplitudes and frequency.
The difference of i-th of reflection wave frequency and emitted frequency may be expressed as:
Wherein, θ is transmitted wave and axial angle；viIt is the speed for moving foam, c is the spread speed of sound wave in water.
The movement velocity of foam is foam relative to the sum of the slippage velocity of water phase and water phase speed:
vi=vs+vw
Wherein, viFor movement velocity, vsSlippage velocity for foam relative to water phase, vwFor water phase speed.
Wherein, slippage velocity v of the bubble phase for water phasegwsBe greater than slippage velocity v of the oil vacuole relative to water phaseows:
vgws> vows
Therefore in back wave, gas phase is mutually exported after Electric signal processing in different frequency bands as a low-frequency electrical with oil
Pressure, may be expressed as:
V=A'1sin(2πf1't)+······+A'isin(2πfi't)
Wherein:
A'1For wave amplitude 1, f1' it is Frequency and Amplitude 1, A'iFor shear wave amplitude i, fi' it is Frequency and Amplitude i.
fi'=fi-f0
This low-frequency voltage signal is subjected to frequency spectrum division, oily phase and gas phase can be respectively obtained:
Oily phase:
Vo=Ao1sin(2πfo1t)+······+Aoisin(2πfoit)
Gas phase:
Vg=Ag1sin(2πfg1t)+······+Agisin(2πfgit)
Wherein oily phase amplitude AoCorresponding oil phase holdup Yo, gas phase amplitude AgCorresponding gas phase holdup Yg；
And water phase holdup YwIt may be expressed as:
Yw=1-Yo-Yg
Aqueous phase flow rate vwIt may be expressed as:
vw=vg-vgws
Then oily, gas and water flow respectively indicates are as follows:
Qo=Yo×vo
Qg=Yg×vg
Qw=(1-Yo-Yg)×(vg-vgws)
Due to Doppler effect, when ultrasonic wave encounters the oil vacuole and bubble of movement, the frequency of back wave can shift, bubble
Body speed is faster, and frequency shift (FS) is bigger, while foam quantity is more, and sound wave reflection amplitudes are bigger, therefore the amplitude pair of back wave
The holdup of phase is answered, the frequency of back wave corresponds to the speed of phase, has the holdup of phase and speed that the flow of phase can be obtained.Because of gas
Phase velocity is greater than oil phase velocity, and gas phase reflection wave frequency is greater than oily phase reflection wave frequency, thus mutually distinguishes gas phase with oil, together
Water phase in one system can finally obtain oil, gas and water three-phase respectively flow by the gain of parameter of gas phase and water phase.
Data acquisition can be completed at 2 minutes or so using each test point of production profile logging instrument of the present apparatus, and
Instrument string speed of going into the well is fast, improves the agility of measurement operation, while the device will not miscarry to underground pressure and fluid situation
Raw to influence, test result ensures instrument not by greasy dirt etc. closer to true production status, the integrated structure structure of device
Factor interference, it is ensured that measurement accuracy, the especially device construct less, are easy to maintain, and not easily damaged, overall cost is lower.
Above specific embodiment has carried out further the purpose of this utility model, technical scheme and beneficial effects
It is described in detail, it should be understood that the above is only the specific embodiments of the utility model, is not used to limit originally practical
Novel protection scope, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done,
