Detailed Description
The present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
It should be understood that the existing steel pipelines for transporting gas and liquid such as oil, natural gas, etc. are usually buried underground, so that the corresponding corrosion prevention measures are required for the equipment to prevent the corrosion of the pipelines. The existing pipeline corrosion is mainly realized by means of arranging an anticorrosive coating, protecting a cathode and the like. The principle of cathodic protection is that a potentiostat or a sacrificial anode is used for providing protection current, a protected steel pipe is used as a cathode, and electron migration is inhibited to prevent metal oxidation. Based on this, the pipeline protection potential is an important data index for evaluating pipeline protection. However, in the related art, the detected value of the pipeline protection potential usually includes the IR drop of the soil, so in order to know whether the pipeline protection potential meets the standard, the IR drop of the environment where the pipeline is located needs to be obtained, but the IR drops of the soil under different environmental conditions are not consistent. Therefore, how to detect and obtain accurate protection potential of the pipeline so as to effectively ensure that the pipeline is in a protection state becomes a technical problem which needs to be solved urgently.
The technical solution of the present invention is further described in detail with reference to the drawings and specific embodiments.
An embodiment of the present invention provides a method for detecting a protection potential of a pipeline, which is executed by a computer device, and fig. 1 is a schematic flow chart of the method for detecting a protection potential of a pipeline according to an embodiment of the present invention, as shown in fig. 1, where the method includes the following steps:
step 101: acquiring the power-off potential of the pipeline;
step 102: determining environmental parameters of the pipeline according to the power-off potential;
step 103: determining the soil IR drop of the environment where the pipeline is located according to the environmental parameters of the pipeline;
step 104: and detecting the protection potential of the pipeline according to the soil IR drop and the power-off potential.
It should be noted that the above method is executed by a computer device, and the computer device is electrically connected with a related sensor for detecting the protection potential of the pipeline, a multimeter or the like. And data calculation processing is carried out based on detection data detected by a related sensor or a multimeter for detecting the protection potential of the pipeline, so that the protection potential of the pipeline is obtained. The computer device can be a mobile phone, a tablet computer, a host computer or any device with data communication and data processing functions.
The pipeline may be a natural gas pipeline or an oil pipeline. Of course, any pipeline buried in the soil for transporting resources may be used, and is not limited herein.
Here, the step 101, namely the acquiring of the power-off potential of the pipeline, includes: and measuring to obtain the power-off potential of the pipeline when the cathode protection current of the pipeline is disconnected for a time less than a preset time. Thereby reducing excessive depolarization on the measurement coupon. It should be noted that the preset time period may be a time period taken for excessive depolarization, and may be 24 hours, for example.
In order to better understand the embodiments of the present invention, specific technical terms involved in the embodiments are explained below.
Natural potential: placing a metal in an electrolyte, such as soil, metal, electrolyte, creates an electric double layer at the interface, with a natural potential between the electric double layers.
It will be appreciated that the measured potential of the pipe prior to cathodic protection being applied is the natural potential. Before measuring the protected pipe, it should first be confirmed that the pipe is in a state where no cathodic protection measures have been applied, and if the pipe to be measured has been applied with a certain amount of cathodic protection measures, it should be selected to be performed after 24 hours of complete power-off. The measurement wiring should then be made according to the cathodic protection design, with the voltmeter ground connected to the reference electrode and the voltmeter anode connected to the protected pipe.
Energization potential: and when the cathodic protection power supply is started, the ground potential of the pipeline is measured by using the reference electrode and a multimeter.
And (3) cathode polarization: when the cathodic protection power supply is activated, current suddenly flows into the pipeline, double layers on the interface of metal and electrolyte are charged, the voltage rises, and the change of the voltage is defined as cathode polarization. Thus, the tubing will typically require cathodic protection.
IR drop: when a cathodic protection current flows through the soil, the resistance of the soil creates a voltage drop, referred to as an IR drop.
Power-off potential: whether cathodic protection meets the specification requirements is judged according to the polarization potential. To obtain the polarization potential of the tube, the cathodic protection current was momentarily interrupted, at which time the potential reading contained no IR drop. The structure-to-electrolyte potential measured at the instant of such outage is referred to as the instantaneous outage potential, which is equal in value to the polarization potential of the pipeline.
Reference electrode: in order to ensure the stability of potential data and important stars, the multimeter is in contact with the electrolyte through a reference electrode during potential measurement. The reference electrode commonly used in soil is a saturated copper sulfate reference electrode.
Referring to fig. 2, fig. 2 is a schematic view of a scene of a method for detecting a protection potential of a pipeline according to an embodiment of the present invention, as shown in fig. 2, V1 is a natural potential of the pipeline, V2 is a cathode polarization of the pipeline, V1+ V2 is a polarization potential of the pipeline, which is equal to a power-off potential of the pipeline, and V1+ V2+ IR is a power-on potential of the pipeline.
It should be noted that the energization potential refers to a measured potential of the pipeline when the cathodic protection system is in operation, that is, a protection potential of the pipeline shown in this embodiment.
Here, the environmental parameters include, but are not limited to, soil condition of soil in the buried pipe, buried depth of the test piece, weather information; wherein, the weather information can be understood as different soil humidity and temperature caused by different weather. In some embodiments, the environmental parameter of the pipeline may be measured from soil collected while the pipeline is buried. However, due to the variable factors of the natural environment, if the soil IR drop is determined according to the environmental parameters obtained by the previous sudden measurement, it is obvious that the obtained IR drop is inaccurate, which also results in the inaccuracy of the protection potential of the pipeline obtained based on the IR drop, and finally results in the pipeline not being cathodically protected, which is not beneficial to the maintenance of the pipeline.
Based on this, experiments prove that the power-off potential and the environmental parameters have a corresponding relation.
Specifically, please refer to table 1, where table 1 is a table showing the influence of soil conditions, burial depth (burying depth) and weather factors on the power-off potential of the test pile, where the test pile is a position where a test piece is inserted, and the test piece is used for simulating a natural gas pipeline in operation.
TABLE 1
As can be seen from Table 1, the power-off potential of the test piece detected in rainy days is more negative than that detected in sunny days under the same soil texture condition; under the same weather condition, the test piece power-off potential detected in the farmland area is more negative than the test piece power-off potential detected in the dry land.
Please refer to table 2, table 2 is a table showing the influence of the soil condition, the burial depth (burying depth) and the burial depth on the power-off potential in the weather factors of the test pile.
| Test pile | Condition of soil texture | Depth of burial | Power-off potential value in rainy day | Depth of burial | Power-off potential value in rainy day |
| FYFC004 | Farmland | 0.8m | -1.121 | 0.4m | -1.085 |
| FYFC006 | Farmland | 0.8m | -1.108 | 0.4m | -1.076 |
| FYFC002 | Dry land | 0.8m | -1.059 | 0.4m | -1.030 |
| FYFC016 | Dry land | 0.8m | -1.022 | 0.4m | -1.004 |
TABLE 2
As can be seen from Table 2, under the same soil texture condition, the outage potential value at the section with the test piece embedding depth of 0.8m is more negative than that at the section with the embedding depth of 0.4 m; the power failure potential value of the farmland area is still more negative than that of the dry land.
Please refer to table 3, table 3 is a table showing the influence of the drawing conditions on the power failure potential in the soil condition, the burial depth (burying depth) and the weather factors of the test pile.
| Test pile | Condition of soil texture | Power-off potential value in sunny days | Depth of burial | Power-off potential value in sunny days |
| FYFC004 | Farmland | -1.115 | 0.4m | -1.075 |
| FYFC006 | Farmland | -1.089 | 0.4m | -1.048 |
| FYFC002 | Dry land | -1.026 | 0.4m | -0.995 |
| FYFC016 | Dry land | -1.008 | 0.4m | -0.978 |
TABLE 3
As can be seen from Table 3, under the same conditions, the power-off potential at the section with the embedded depth of 0.8m of the test piece is more negative than the power-off potential at the section with the embedded depth of 0.4 m; the outage potential of the farmland area is still more negative than that of the dry land.
Thus, research finds that the numerical value of the outage potential has a certain corresponding relation with the IR drop of the soil.
Based on this, in some embodiments, the method comprises:

the step 102 of determining the environmental parameter of the pipeline according to the power-off potential includes:
and determining the environmental parameter corresponding to the power-off potential according to the corresponding relation between the power-off potential and the power-off potential.
In some embodiments, the computer device may obtain an experimental power-off potential and experimental environment parameters obtained by an experiment through the input control; the establishing of the corresponding relationship between the power-off potential and the environmental parameter may include: and establishing a corresponding relation between the power-off potential and the environmental parameters according to the experimental power-off potential and the experimental environmental parameters.
The experimental power-off potential can be the power-off potential obtained in the experimental process; the experimental environment parameters can be the environment parameters set in the experimental process.
Thus, real-time environmental parameters can be obtained according to the detected power-off potential.
In addition, because the soil IR drop that the different environments of pipeline correspond is different, in some embodiments, can acquire the soil IR drop of corresponding environment from the high in the clouds through the environment that the pipeline is located.
It should be noted that the protection potential of the pipeline is in the range of-0.85 Vcse to-1.20 Vcse. In some embodiments, determining whether the protection potential is within a national standard range according to the detected protection potential of the pipeline; if the current time is not within the national standard range, a maintenance prompt is sent.
In the embodiment, the environmental parameters of the pipeline are determined by acquiring the power-off potential of the pipeline and according to the power-off potential; then determining the soil IR drop of the environment where the pipeline is located according to the environmental parameters of the pipeline; and finally, detecting the protection potential of the pipeline according to the soil IR drop and the power-off potential, thereby obtaining the protection potential with higher accuracy, further timely determining whether the protection potential of the pipeline is in a standard range, providing favorable guarantee for the cathodic protection of the pipeline, and further being favorable for the maintenance of the pipeline.
It should be noted that, the water content and the compactness of the soil are different in the soils with different soil qualities, and the IR drop of the soil is also different. In order to obtain an accurate IR drop value, in dry land and where the soil is dry, the measurement may be carried out by pouring a large amount of water or by pouring a salt solution to fill the soil.
Based on this, in some embodiments, the method further comprises:
determining weather information of a preset time period, wherein the preset time period at least comprises the time period of the day;
sending an irrigation prompt in response to the weather information indicating that the soil is dry;
