Specific embodiment
With reference to the attached drawing in the embodiment of the present invention, detailed description of the present invention implementation process.
As shown in Figure 1 be oil pipeline model, material be it is nonmetallic, measurement be largely divided into two processes:
First process, as shown in Fig. 2, to determine that 8 transceivers emit signal amplitude phase process.In oil pipeline 1
The middle transmitter 2 for placing a transmitting wideband pulse signal, it is equal with the geometric center circumference of oil pipeline 1 outside oil pipeline 1
Cloth places 8 transceivers 3 of circle to receive the wideband pulse signal of the sending of the transmitter 2 in oil pipeline 1.
Second process, as shown in figure 3, removing the wideband pulse signal transmitter 2 in oil pipeline 1.
Then emit signal simultaneously by 8 transceivers 3 outside oil pipeline 2, according to time reversal principle, by receiving
Characteristics of signals adjustment oil pipeline 1 outside place 8 transceivers 3 amplitude-phase.
If transmitter 2 is located at r0, transmitting signal is P (ω), and the transceiver of surrounding is located at rk, then transceiver transmitting signal
It is determined by formula (1):
ET(rk, ω) and=P (ω) GF(rk,r0,ω) (1)
Wherein GF(rk,r0, ω) and it is preceding to Green's function.
It places a measuring signal transceiver 4 again outside oil pipeline 2 and specially receives signal.
4 received signal of transceiver being located at r can be obtained to determine for formula (2):
When conveying the oil containing different in moisture, Green's function can change, and change the width that transceiver 4 receives signal
Spend phase.We can obtain this variation with the rule of moisture content by experiment, then calculate moisture content therein.This
In to moisture measurement when due to oil composition and moisture impurity constitute difference and pipeline configuration and size difference,
The amplitude-phase E (r, t) that similar moisture content transceiver 4 measurement when different occasions measure obtains signal can be variant.Therefore
Need to need first to measure measured pipeline configuration before measuring under different occasions, varying environment a series of feelings of known moisture contents
Condition is calibrated, and is obtained corresponding table of the E (r, t) with water content, is then measured work, accurately measured and analyzed.
For example, being measured in land somewhere oil field to moisture in oil pipeline, then first in same structure pipeline
The moisture and oil for conveying identical component, obtain corresponding table of the E (r, t) with water content according to above-mentioned steps, then can be herein
Ground measures, and finds water content data from obtained E (r, t).
If at sea certain drilling platforms measures moisture in oil pipeline, first conveyed in same structure pipeline
The moisture and oil of identical component obtain another corresponding table of the E (r, t) with water content according to above-mentioned steps, then can be
This place measures, and finds water content data from obtained E (r, t).
It is as shown in Figure 4: transmitter 2, transceiver 3, the emission principle process of measuring signal transceiver 4 are as follows: setting amplitude and
Phase and wave memorizer, input microprocessor (MPU), obtain desired signal, then carry out DA conversion, pass through amplifier
(PA) launched with antenna.
It is as shown in Figure 5: transmitter 2, transceiver 3,4 record principle process of measuring signal transceiver are as follows: antenna receives signal
By low noise (LNA) and down coversion is carried out afterwards, then after AD conversion by microprocessor (MPU), output amplitude and phase,
Record amplitude and phase.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art within the technical scope of the present disclosure, the variation or replacement that can be readily occurred in, all
It is covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection scope of claims
Subject to.
