Specific embodiment
As shown in Figure 1, the present invention provides a kind of deepwater field production of hydrocarbons leakage false alarm experimental system and method.Institute
Stating experimental system includes experimental tank 12, gas source power station 11, the first gate valve 14, the second gate valve, needle-valve 15, the monitoring of underwater sonar
Unit, control device 13.Illustratively, two 3 cun of gate valves and 1/2 cun of needle-valve can be used.
Wherein, two gate valve disposed adjacents (as integrated or binding together), are collectively disposed in the water in experimental tank 12;
First gate valve 14 is for simulating subsea production system (such as deepwater field production key equipment), and gas source power station 11 is with hose 19
Be connected to the input terminal of the first gate valve 14, to it inside be filled with the gas of relevant pressure, for simulating subsea production system production oil
The case where gas;The output end of first gate valve 14 connects needle-valve 15 by hose 19 can be with when manipulation needle-valve 15 unclamps a little
Simulate oil and gas leakage.When the gas that pipeline is filled with reaches certain pressure, leaked gas generates bubble in water at needle-valve 15.
Second gate valve non-aerating can not also configure needle-valve, be opened and closed repeatedly by operating it come simulation background noise.By being placed on pond
The interior hydrophone 16 not far from one another with two gate valves receives voice signal, and successively by sonar noise meter 17, noise amplifier 18
After processing, it is transmitted to control device 13 and subsequent analysis is carried out to waveform, frequency spectrum, parameter of voice signal etc., and pass through support
The interface of the operating platform of human-computer interaction carries 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 the first gate valve 14, operation is opened or closed to needle-valve 15, operation etc. is opened or closed to the second gate valve.
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, and judge whether there is ambient noise.It is the power spectrum signal acquired in a particular embodiment shown in Fig. 2.
By the waveform and frequency spectrum of checking signal, it can be seen that power spectrum is relatively flat when No leakage, and spectral line has when having leakage to occur
Significant change (at arrow 200), have powerful connections noise when spectral line there will be apparent another variations (at arrow 200).Wherein, have
The main energetic of voice signal all concentrates in 2.5-3.2kHz frequency band when leakage, analyzes the signal in this frequency range, so that it may
Meet the requirement of positioning leak position.The main energetic of ambient noise then concentrates in 10.5-14.5kHz frequency band.
It therefore, can be respectively when the second gate valve generates or does not generate the ambient noise of simulation, by underwater in experiment
Sonar monitoring unit collected sound signal is simultaneously analyzed by control device.When second gate valve generates ambient noise, if
Voice signal corresponding frequency spectrum when control device 13 still can correspondingly analyze gas leakage, and by itself and ambient noise pair
The frequency spectrum answered successfully distinguishes, then it is assumed that system meets related request, will not false alarm.
Fig. 3~Fig. 6 is the alert interface schematic diagram of operating platform in the embodiment of the present invention.In this example, hydrophone and needle
The distance between the leakage point of valve simulation is 1.5m, test pressure 2000psi.The early warning time started is 14:14:20, corresponding control
The starting time of device processed or resetting time;In 14:17:30 the amplitude of signal be -48.53dB, frequency be 2543.69Hz into
Enter (Fig. 3) in the range of 2.5-3.2kHz, in the first time period thus started, constantly collected sound signal, this example
In be 2 points 10 seconds (Fig. 4) between 14:17:30 to 14:19:40, the specific value of the first time period can be by the people that works
Member sets on control device.In second time period, to the frequency of the voice signal acquired in above-mentioned first time period whether
Judged within the above range, if frequency is substantially within the scope of this, judgement has leakage, and carries out police instruction;
Second time period in this example triggers alarm indication signal from 14:19:40 to 14:23:15, in 14:23:15, and (alarm refers in Fig. 5
Show that lamp changes colour), alert reaction time of the second time period correspondence system be 3 points 35 seconds.In the example of Fig. 6, the frequency of signal
For 13028.41Hz, fall into the corresponding frequency band 10.5-14.5kHz of ambient noise, 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.
