Said structure join water flooding well pipe external flux ultrasonic doppler measurements instrument, work process can be:
Measuring instrument is transferred between two injection allocation layers, during transferring, at all parts of measuring instrument
In off working state, actuating sleeve is positioned at the bottom of drive rod, upper support shell fragment and lower support shell fragment and is in vertically
State, ultrasonic probe and supporter are under the supporting role of upper support shell fragment and lower support shell fragment, with upper support
Shell fragment and lower support shell fragment are on identical vertical plane, and due to upper support shell fragment and lower support shell fragment respectively
It is connected with fixed mechanism and drive mechanism, so, upper support shell fragment and lower support shell fragment are positioned at probe storehouse,
And then, ultrasonic probe, supporter, upper support shell fragment and lower support shell fragment are respectively positioned in probe storehouse；
After the test point between two injection allocation layers transferred to by measuring instrument, drive mechanism is started working, and actuating sleeve exists
Under dynamic action, stop sliding, in the mistake of actuating sleeve upward sliding along drive rod upward sliding to limited block
Cheng Zhong, can support shell fragment under upwardly extruding, make lower support shell fragment that the bending towards tube inner wall to occur,
Supporter is driven to move to tube inner wall；Meanwhile, the promotion squeezing action of the actuating sleeve that lower support shell fragment is subject to,

Ripple is formed at contaminant surface to be launched, and the frequency of echo offsets compared with the frequency of transmitted wave, and side-play amount is with miscellaneous
The speed of matter is relevant, and impurity is synchronized with water, measures frequency offset and can record water velocity, due to oil pipe
And the sectional area between sleeve pipe is fixed, and then discharge can be recorded.
Let c be sound wave spread speed in water, f0Being acoustic emission frequency, Δ f is reflection sound wave and transmitting sound
The difference on the frequency of ripple, θ is acoustic emission angle, then according to Doppler effect, rate of flow of fluid is:
If S1 is casing inner diameter sectional area, S2 is oil pipe external diameter sectional area, then fluid flow is:
Q=v (S1-S2)
Use the measuring instrument that the present embodiment provides, not only achieve employing Ultrasound Doppler Method and measure injection allocation well
The purpose of the discharge between oil pipe and sleeve pipe, make Ultrasound Doppler Method measure injection allocation well oil pipe and sleeve pipe it
Between discharge enter from theoretical research stage and put into practice measuring phases, make the injection profile of injection allocation well measure
Process had both avoided environmental pollution, reduced again cost, and the measurement of said structure that the present embodiment provides
In instrument, telescopic upper support shell fragment, supporter, ultrasonic probe and lower support shell fragment, both can ensure that measurement
Instrument can transfer the test point to oil pipe smoothly, will not due between injection allocation layer narrow space by shadow
Ring, can ensure that again the receiving plane of ultrasonic probe and the surface of emission can be close on tube inner wall, make via sending out
The ultrasound wave penetrating surface launching can pass through tubing wall smoothly, enters between oil pipe 12 and sleeve pipe 13 from oil pipe,
