Description

Gathering and transportation pipeline corrosion and leakage test system

Technical Field

The present application relates to the field of pipeline corrosion and leakage detection, and in particular to a gathering and transportation pipeline corrosion and leakage test system.

Background technique

Pipeline transportation is an efficient and convenient way to transport oil and gas. Due to factors such as pipeline corrosion, natural environment, and human damage, pipeline leakage occurs from time to time. Pipelines are subject to different degrees of erosion corrosion or electrochemical corrosion due to different materials, locations, types of transported media, and transport conditions (temperature, pressure, etc.), which can lead to pipeline leakage accidents. Pipeline leakage will not only cause serious economic losses and pollute the ecological environment, but also have negative social impacts. Real-time monitoring of pipeline leakage and timely and accurate positioning of pipeline leakage points when pipeline leakage is found are crucial to maintaining pipeline safety and minimizing the risk of loss caused by leakage during oil and gas transportation.

The relevant pipeline leakage monitoring and positioning technologies mainly include manual inspection, pressure difference method, etc. In the actual application process, due to the pipeline not being fully loaded or the pressure imbalance at the pipeline head and end stations, the single pipeline leakage monitoring and positioning technology may have problems such as noise interference, low monitoring sensitivity, and large errors, resulting in inaccurate monitoring and high false alarm rate. At present, there is a lack of effective pipeline leakage monitoring and positioning technology that integrates multiple detection technologies, as well as pipeline corrosion evaluation methods for different pipeline materials, parameters, different conveying medium components, temperatures, pressures and other working conditions. That is, in the relevant technologies, manual methods are generally used to evaluate the degree of pipeline corrosion, leak monitoring and positioning, which have the problems of single technology, time-consuming and labor-intensive, and large errors.

To address the above-mentioned problems, no effective solution has been proposed yet.

In some optional embodiments of the present application, the corrosion simulation pipeline 20 and the leakage simulation pipeline 30 are connected in parallel to the circulation pipeline 100 through a three-way valve 70, wherein the leakage simulation pipeline 30 is provided with at least one set of solenoid valves 300 and leakage holes 302 corresponding to the solenoid valves 300.

For example, when the opening of the leakage hole 302 is adjusted to a larger value, the leakage duration can be set to a longer time, so as to simulate a situation where the leakage is relatively large.

It should be noted that the leakage hole 302 can be a leakage hole with adjustable gap shape and size. The leakage hole 302 is used to receive the control signal of the data processing system 50 through the communication module 40, and adjust the gap shape and/or size of the leakage hole through the processor corresponding to the leakage hole 302, so as to simulate different leakage conditions, wherein the gap shape is a shape simulated according to the shape of the gap when the leakage actually occurs. It should be noted that the gap shape includes but is not limited to: triangle, circle, rectangle, trapezoid and various irregular images, so as to simulate the gap shape when the pipeline leaks in various different situations.

In some optional embodiments of the present application, the leakage simulation pipeline 30 is provided with a plurality of leakage pipe pressure sensors 304 , and the leakage pipe pressure sensors 304 are used to detect the pressure of the leakage simulation pipeline 30 .

In some optional embodiments of the present application, the data processing system 50 is used to receive corresponding collection signals from the inlet and outlet ends of the circulation pipeline 100 respectively; and compare the sizes of the collection signals at the inlet and outlet ends, and determine the leakage status of the leakage simulation pipeline according to the comparison results.

In some embodiments of the present application, the data processing system 50 is used to receive the infrasonic signal in the collected signal. After receiving the infrasonic signal, the data processing system 50 determines that the flow signal size corresponding to the inlet end is greater than the flow signal size corresponding to the outlet end, and the negative pressure wave signals at the inlet end and the outlet end are both reduced, then it is determined that the leakage simulation pipeline is leaking; the data processing system 50 is used to receive the infrasonic signal in the collected signal. After receiving the infrasonic signal, the data processing system determines that the flow signal size corresponding to the inlet end and the flow signal size corresponding to the outlet end have not changed, and the negative pressure wave signals at the inlet end and the outlet end have not changed or the change trends are the same, then it is determined that the leakage simulation pipeline is not leaking.

In some optional embodiments of the present application, the data processing system 50 is also used to receive the infrasonic signal in the collected signal, and determine the corrosion location of the corrosion simulation pipeline 20 according to the echo signal of the infrasonic signal.

In some optional embodiments of the present application, the data processing system 50 is further used to determine the first position where the leakage occurs in the leakage simulation pipeline 30 according to the time difference of the infrasound wave signal and/or the negative pressure wave signal in the collected signal from the inlet end to the outlet end and the transmission speed of the infrasound wave and/or the negative pressure wave signal in the leakage simulation pipeline 30. For example, according to the infrasound wave signal generated at the leakage point in the pipeline propagating along the pipeline to the inlet end and the outlet end at a constant speed, the position of the leakage point from the inlet end can be located according to the propagation time difference, for example, by the formula: l ₁ =1/2×[L+Δt×v];

Wherein, _l1 is the distance from the leakage point to the inlet end, L is the total length of the pipeline, v is the propagation velocity of infrasound, and Δt= _t1 - _t2 is the time difference between the inlet end and the outlet end sonic sensor receiving the data signal.

In some optional embodiments of the present application, the data processing system 50 is also used to compare the first position with the second position, and adjust the monitoring accuracy of the data processing system 50 according to the comparison result, wherein the second position is the position where the leakage actually occurs in the leakage simulation pipeline 30. For example, the data processing system 50 analyzes the collected signals and shows that the leakage occurs at the leakage hole A (at the first position), but in fact the leakage occurs at the leakage hole B (at the second position). The data processing system can adjust its own processing algorithm according to the position difference between the leakage hole A and the leakage hole B to further improve the monitoring accuracy.

Specifically, the above judgment process can be implemented by the following method:

Step 1: Use water as the medium to conduct pipeline corrosion and leakage monitoring experiments. First, ensure that the entire experimental platform is intact, open the three-way valve and the three-way valve until the leakage simulation pipeline is unobstructed and sealed, start the central control computer (i.e., data processing system), and open the control software for online monitoring and data collection, analysis, and identification.

Step 2: After an appropriate amount of water is stored in the tank, turn on the circulation pump, set the centrifugal water pump to a certain speed value (frequency value), keep the water flow in the corresponding pipeline constant, turn on the tank heater, set the temperature value, and fill the experimental platform pipeline with circulating water.

Step 3: The liquid flow meter, two detectors, pressure sensor and temperature sensor at the inlet end of the circulation pipeline and the flow meter, two detectors, pressure sensor and temperature sensor at the outlet end of the pipeline respectively record the infrasonic wave signal, negative pressure wave signal, flow data and temperature data at the inlet and outlet ends of the pipeline under this normal state, and the data signal is transmitted to the central control computer through the signal acquisition transmitter.

Step 4: Analyze the collected data signals, specifically: control the start and stop of the furnace heater by comparing and analyzing the temperature values at the inlet and outlet of the pipeline; compare and analyze the flow meters at the inlet and outlet and the flow meter data and detector information within the data signal acquisition accuracy error range. When the central control computer displays an infrasonic signal, and the volume flow at the outlet of the pipeline is less than the volume flow at the inlet, and the negative pressure wave signals at the inlet and outlet decrease, it can be determined that the pipeline has a leak; when the central control computer displays an infrasonic signal, and the volume flow and negative pressure wave signals at the inlet and outlet remain unchanged or increase or decrease at the same time, it is determined that the pipeline is normal.

The central control computer opens the electromagnetic ball valve of the standard leakage hole of the pipeline, simulates the pipeline leakage, selects a leakage hole of a certain size, and the leakage lasts for 10 minutes. The software reads the signals and data of the liquid flow meter, detector, pressure sensor and temperature sensor at the inlet end of the line and the flow meter, detector, pressure sensor and temperature sensor at the outlet end of the pipeline during this period. The sensor measures the time for the signal to be transmitted to the inlet and outlet ends of the pipeline, the signal transmission speed in the pipeline, and the spectral signal is analyzed. The position of the pipeline leakage point is calculated by the infrasound or negative pressure wave time difference positioning method.

Taking the infrasound monitoring method as an example, the pipeline leakage point is located. Specifically, the infrasound signal generated at the leakage point in the pipeline propagates along the pipeline to the inlet and outlet ends at a constant speed. The position of the leakage point from the inlet end can be located according to the propagation time difference.

Formula 1: l ₁ = 1/2 × [L + Δt × v]

Wherein, _l1 is the distance from the leakage point to the inlet end, L is the total length of the pipeline, v is the propagation velocity of infrasound, and Δt= _t1 - _t2 is the time difference between the inlet end and the outlet end sonic sensor receiving the data signal.

Taking the negative pressure wave monitoring method as an example, the pipeline leakage point is located. Specifically, the negative pressure wave generated at the leakage point in the pipeline propagates to the inlet and outlet ends with the leakage point as the center. By measuring the time difference between the negative pressure wave reaching the detector at the pipeline inlet and outlet and the propagation speed of the negative pressure wave in the pipeline, the position of the pipeline leakage point can be calculated.

Formula 2: L ₁ = 1/2 × [L + ΔT × V]

Wherein, _L1 is the distance from the leakage point to the inlet end, L is the total length of the pipeline, V is the propagation speed of the negative pressure wave in the pipeline medium, and ΔT= _T1 - _T2 is the time difference between the inlet end detector (121) and the outlet end detector (132) receiving the data signal.

The measured data of the leakage point location and the actual real data are compared to further calculate the monitoring accuracy of the experimental platform.

A standard leakage hole of a certain size is selected, and the central control computer opens the pipeline electromagnetic ball valve. The leakage lasts for 5 minutes, simulating leakage at different positions of the pipeline. The above process is repeated for detection.

After the simulated leakage experiment is completed, the air inlet pipe valve can be opened to carry out gas-liquid mixed medium or air-air purge to drain the water in the pipeline and then conduct corrosion and leakage monitoring experiments of air medium, change the medium temperature in the circulation pipeline, change the standard leakage hole shape, opening, leakage duration and leakage point position to simulate different working conditions, and repeat the experimental steps.

Open the three-way valve and the three-way valve to switch the pipeline to the leakage simulation pipeline, keep the corrosion simulation pipeline unblocked, and use the detector and detector information to monitor the echo signal caused by the structural defects of the corrosion part to conduct corrosion monitoring. Repeat the above process for detection to simulate different situations.
