Specific embodiment
As shown in Figure 1, the present invention provide a kind of deepwater field production of hydrocarbons leakage point location and alarm experimental system and
Method.The experimental system include experimental tank 12, gas source power station 11, gate valve 14, needle-valve 15, underwater sonar monitoring unit,
Control device 13.Illustratively, 3 cun of gate valves and 1/2 cun of needle-valve can be used.
Wherein, gate valve 14 is placed in the water in experimental tank 12, and for simulating subsea production system, (such as deepwater field is raw
Produce key equipment)；Gas source power station 11 is connected to the input terminal of gate valve 14 with hose 19, to it inside be filled with the gas of relevant pressure
Body, for simulating the case where subsea production system produces oil gas；The output end of the gate valve 14 connects needle-valve 15 by hose 19,
When manipulation needle-valve 15 unclamps a little, oil and gas leakage can be simulated.When the gas that pipeline is filled with reaches certain pressure, at needle-valve 15
Leaked gas generates bubble in water, and the voice signal of sending can be connect by being placed on the hydrophone 16 in pond nearby
It receives, and after successively by sonar noise meter 17, the processing of noise amplifier 18, is transmitted to control device 13 to the wave of voice signal
Shape, frequency spectrum, parameter etc. carry out subsequent analysis, and by supporting the interface of the operating platform of human-computer interaction to carry out result presentation.
If voice signal that underwater sonar monitoring unit measures and its analysis as a result, be with relevant device in this experimental system
If the actual arrangement done of simulation production of hydrocarbons and operation are consistent, illustrate the underwater sonar monitoring unit and control device 13
Function is complete.It, can also be further in reality using the underwater sonar monitoring unit and control device 13 Jing Guo functional verification
It tests under environment or site environment, test subsea production system is with the presence or absence of leakage and to leakage point location.Equipment described above
Actual arrangement and operational circumstances, the distance between the leakage point e.g. simulated and hydrophone 16, whether gas source power station 11
It is supplied to gate valve 14, operation etc. is opened or closed to needle-valve 15.
By analyzing the power spectrum of voice signal, it can determine whether that subsea production system or its simulation system have No leakage and determine
The position of position leakage.It is the power spectrum signal acquired in a particular embodiment shown in Fig. 2.By the waveform and frequency of checking signal
Spectrum, it can be seen that the main energetic of voice signal all concentrates in 2.5-3.2kHz frequency band when leakage, analyzes in this frequency range
Signal, so that it may meet the requirement of positioning leak position.
The present invention carries out multi collect and carries out time delay to estimate after detecting with the presence of leakage to voice signal when leaking
Meter, may further determine that leak source position.Figure it is seen that power spectrum is relatively flat (from amplitude, all when No leakage
In 60dB hereinafter, can be ignored), when there is leakage to occur, spectral line has significant change, and energy all concentrates on 2.5-
Between 5kHz, preferably between 2.5-3.2kHz.At this moment the cutoff frequency that digital filter can be set, by denoising
It show that time delay value is 2.687ms with the voice signal that general cross correlation is analyzed when leaking after reason, thus calculates leak source distance
Hydrophone 1.492m approaches at a distance from the leak point of hydrophone and needle-valve simulation when with actual arrangement, repeats above procedure
10min, spectral line when measuring all leakages are almost the same.
The present embodiment has been surveyed ten times under the same conditions, obtains ten groups of data, as shown in the table:
Table leak point positioning tests delay value
The average value 2.745ms of delay value is taken, calculates leak source apart from sonar 1.521m, mistake very identical with actual conditions
Poor ≈ 1.18% illustrates that general cross correlation is that effectively, system positioning leakage point through the invention is successful.
Fig. 3~Fig. 6 is the alert interface schematic diagram of operating platform in the embodiment of the present invention.The early warning time started of this example
For 14:14:20, the starting time or resetting time of corresponding control device；In 14:17:30, the amplitude of signal is -48.53dB,
Frequency is that 2543.69Hz enters in the range of 2.5-3.2kHz (Fig. 3), in the first time period thus started, constantly
Collected sound signal is 2 points 10 seconds (Fig. 4) between 14:17:30 to 14:19:40, the tool of the first time period in this example
Body numerical value can be set on control device by staff.In second time period, to what is acquired in above-mentioned first time period
Whether the frequency of voice signal is judged within the above range, if frequency is substantially within the scope of this, judgement is let out
Leakage, and carry out police instruction；Second time period in this example refers to from 14:19:40 to 14:23:15 in 14:23:15 triggering alarm
Show signal (in Fig. 5 alarm lamp change colour), the alert reaction time of the second time period correspondence system be 3 points 35 seconds.Fig. 6's
In example, the frequency of signal is 13028.41Hz, exceeds above range, thus without alarm.
It is discussed in detail although the contents of the present invention have passed through above preferred embodiment, but it should be appreciated that above-mentioned
Description is not considered as limitation of the present invention.After those skilled in the art have read above content, for of the invention
A variety of modifications and substitutions all will be apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
