Description

Technical Field

[0001] This invention relates to the field of cathodic protection design technology for oil and gas station areas, and in particular to a regional cathodic protection design method and system based on typical operating conditions of the station. Background Technology

[0002] Regional cathodic protection technology refers to cathodic protection implemented for buried metal pipelines, tanks, and equipment within sites (mining areas), stations (transportation), and storage facilities (oil depots, gas storage facilities). Currently, the design of regional cathodic protection follows SY / T 6964-2011 "Technical Specification for Cathodic Protection of Oil and Gas Stations" or GB / T35508-2017 "Regional Cathodic Protection within Stations." This involves first estimating the protection current density of the protected object, then calculating the area of ​​the pipeline facilities to be protected, obtaining the required current demand, and further proposing a design scheme.

[0003] Production practice shows that stations designed using this method often suffer from inadequate protection in areas with dense pipeline networks and dense grounding points. According to preliminary statistics on the effectiveness evaluation of regional cathodic protection in over 60 in-service stations, nearly 80% of the stations exhibited inadequate protection. Substandard regional cathodic protection increases the corrosion risk of buried pipeline facilities. Analysis indicates that the main reasons for substandard regional cathodic protection include: complex buried metal structures in the stations, a large grounding system leading to significant current loss, severe interference and shielding issues between pipelines and between pipelines and the grounding grid, significant regional limitations on auxiliary anode bed construction, numerous system loops, and difficulties in commissioning and testing. Therefore, this traditional design method cannot guarantee full coverage of regional cathodic protection effectiveness for oil and gas stations, such as oil and gas transportation stations.

Based on the optimized anode bed parameters and distribution location corresponding to the typical cathodic protection conditions of each station area, the regional cathodic protection design scheme for each typical cathodic protection condition of each station area is determined. Based on the regional cathodic protection design scheme for each typical working condition of the station area, the regional cathodic protection design scheme for the target oil and gas station is obtained.

[0005] The beneficial effects of the regional cathodic protection design method based on typical operating conditions of a station provided by this invention are as follows: Through numerical simulation technology and field power supply test studies under typical operating conditions, a design scheme for cathodic protection under typical regional conditions is derived. This scheme can be extended to other stations with similar operating conditions. The regional cathodic protection design scheme for the entire station can be obtained by combining typical operating conditions, thereby improving the effectiveness of the design, enhancing the cathodic protection level of the station, and reducing the corrosion risk of buried pipeline facilities.

[0006] 2) Secondly, the present invention also provides a regional cathodic protection design system based on typical operating conditions of a station, the specific technical solution of which is as follows: It includes a typical working condition determination module, an optimization module, a determination module, and a scheme determination module; The typical operating condition determination module is used to determine the typical operating conditions of cathodic protection in various station areas of oil and gas stations.

Determine the typical operating conditions of cathodic protection in various areas of oil and gas stations, specifically: Through the evaluation and analysis of the effectiveness of cathodic protection in more than 60 oil and gas station areas, typical operating conditions of buried pipelines inside oil and gas stations were obtained, including three types of typical cathodic protection operating conditions in station areas: typical cathodic protection operating conditions in station areas with isolated pipelines, typical cathodic protection operating conditions in station areas with dense pipelines, and typical cathodic protection operating conditions in station areas with pipelines near grounding electrodes.

[0013] S2.

S3.

S4. Based on the regional cathodic protection design scheme for each typical working condition of the station area, the regional cathodic protection design scheme for the target oil and gas station is obtained.

[0014] Optionally, in the above technical solutions, the process of optimizing the anode ground bed parameters and distribution location corresponding to any typical cathodic protection working condition in a station area includes: S20. Conduct a power supply test for any typical cathodic protection operating condition in any station area, specifically: For any typical operating condition of cathodic protection in a station area, select the actual typical operating environment of the station and carry out on-site power supply test to clarify the electric field distribution and current attenuation law.

Optimize the anode ground bed parameters and distribution location based on the polarization boundary conditions.

[0016] Optionally, in the above technical solution, S20 specifically includes: S200. Perform three-dimensional modeling of the geometric distribution and soil resistivity information of buried components in any typical cathodic protection working condition of a station area.

[0017] In another embodiment, such as Figure 2 As shown, it includes: S101. Determine typical operating conditions for cathodic protection in various station areas: Through the evaluation and analysis of the effectiveness of cathodic protection in more than 60 oil and gas station areas, typical operating conditions of buried pipelines inside oil and gas stations were obtained, including three types of typical cathodic protection operating conditions in station areas: typical cathodic protection operating conditions in station areas with isolated pipelines, typical cathodic protection operating conditions in station areas with dense pipelines, and typical cathodic protection operating conditions in station areas with pipelines near grounding electrodes.

[0018] S102. Conduct on-site power supply tests to clarify the power supply test results for three typical operating conditions of cathodic protection in the station area, specifically: Based on the three typical operating conditions of cathodic protection in the proposed station area, the environment of the actual station area cathodic protection typical operating conditions was selected, and on-site power supply tests were carried out to obtain the power supply test results of the three typical operating conditions of cathodic protection in the station area. The power supply test results include the electric field distribution law and the current decay law.

[0019] S103. Three-dimensional modeling and anode bed optimization for typical cathodic protection conditions in the station area: Three-dimensional models were developed for three typical cathodic protection conditions in three station areas. Polarization boundary conditions were obtained through inversion calculations based on the results of power supply tests. Anode ground bed parameters and distribution locations were optimized through numerical simulation calculations.

[0020] S104. Determine the anode ground bed design principles for typical cathodic protection conditions in each station area: Based on on-site power supply tests and numerical simulation calculations, the design principles for the regional cathodic protection anode ground bed parameters and distribution locations for typical operating conditions of cathodic protection in each station area were determined.

[0021] S105. Determine the cathodic protection design scheme for the entire station area: The regional cathodic protection design scheme for the entire target oil and gas station is obtained by combining multiple cathodic protection schemes for typical operating conditions. The target oil and gas station refers to the oil and gas station for which the regional cathodic protection design scheme needs to be determined.

[0022] S106. Real-world case verification: The regional cathodic protection design method based on typical operating conditions of oil and gas stations according to the present invention was applied to the regional cathodic protection renovation project of newly built oil and gas stations or existing oil and gas stations to verify the effectiveness of the present invention, and the model was corrected based on the actual verification results.

[0023] S107. Determine the precise design principles for typical operating conditions of cathodic protection in the station area: Based on the verification and correction results of test cases, a precise design principle for regional cathodic protection based on typical operating conditions of stations was formed, and its application was promoted to the regional cathodic protection design of newly built and existing stations.

[0024] The typical cathodic protection condition for station areas in isolated pipeline zones refers to a relatively isolated situation where there are few other structures surrounding the buried pipeline in certain areas of the station. Under this condition, interference and shielding effects are minimal, and there is sufficient construction space. The following section uses the typical cathodic protection condition of an isolated pipeline zone as an example to illustrate a regional cathodic protection design method based on this invention. Figure 3 As shown, it includes: S1001, On-site power supply test: The power supply test involves using a temporary cathodic protection system (temporary power supply and anode ground bed) to conduct an electric polarization test on the object to be protected. Based on this, the protection current requirements of different areas are obtained, and the difficulty of protection in different areas is compared. The power supply test results for a certain oil and gas station are shown in Table 1.

[0025] Table 1: S1002, 3D Modeling: For any typical cathodic protection working condition in a station area, a three-dimensional model is created based on the geometric distribution of buried components and soil resistivity information. The resulting three-dimensional geometric model is as follows: Figure 4 As shown. The upper left region of the model is an isolated pipe area. The established geometric model was meshed using the commercial boundary element software BEASY, and the mesh is shown below. Figure 5 As shown, a mathematical model of regional cathodic protection for a given station is constructed based on the electric field distribution of the cathodic protection system. The established mathematical model of regional cathodic protection for a given station can be solved using the BEASY boundary element method (BEM) program, based on the defined boundary element mesh.

[0026] S1003, Inversion Calculation of Cathodic Polarization Boundary Conditions: In the mathematical model of regional cathodic protection potential distribution, the polarization characteristics of buried pipelines serve as a crucial polarization boundary condition, directly impacting the accuracy of numerical calculation results. Therefore, the accuracy of polarization characteristic measurement is paramount. The polarization characteristics of buried pipelines are a comprehensive reflection of the polarization behavior of pipeline steel in the soil and the condition of the anti-corrosion coating on the pipeline's outer surface. For buried pipelines that have been in service for many years, it is difficult to directly measure and obtain accurate polarization characteristics. We utilize the results of field power supply tests to inversely calculate the polarization boundary conditions of buried pipelines in different regions.

[0027] Based on the existing operating parameters of the cathodic protection system, field power supply test data, and test point potential information, the polarization characteristics of the pipeline with the anti-corrosion layer are adjusted by continuously changing the resistivity and damage rate of the anti-corrosion layer. The field power supply test potential data is used as a comparison condition to finally obtain the polarization boundary conditions of the pipeline with the anti-corrosion layer. If the error between the inverted pipe-to-ground potential and the power supply test data is approximately less than 10%, it indicates that it can reflect the actual polarization condition. The polarization characteristic curve obtained from the inversion is shown below. Figure 6 As shown.

[0028] S1004, Optimization of the anode bed: In isolated pipeline areas, the pipelines are relatively independent, and there are no other metal structures around them, allowing for some construction space. For example... Figure 7 As shown, when there is one auxiliary anode, its length is 2 meters, the output current is 1~2A, and the closest distance between the anode and the adjacent pipe is 3 meters, the cathodic protection range of the pipe closest to the single anode is about 10 meters, and the cathodic protection range of the second pipe is about 6 meters; as the distance between the anode and the adjacent pipe increases, such as Figure 8 As shown, when the distance is increased to 5 meters, the cathodic protection range of the pipe closest to a single anode increases to approximately 16 meters, while the cathodic protection range of the second pipe is approximately 10 meters; (e.g., ...) Figure 9 As shown, when the distance between the anode and the pipe is 8 meters, the cathodic protection range of the pipe near the single anode increases to about 22 meters, and the cathodic protection range of the second pipe is about 18 meters, but the output current of the single anode here is 4.7A. From the above cathodic protection effect of the single anode, as the distance between the anode and the pipe gradually increases, the cathodic protection range also gradually increases, but the output current of the anode also gradually increases.

[0029] An anode bed is set up in this area, and the anodes are distributed as follows: Figure 10 As shown, three sets of anode ground beds were set up in area 1 and two sets of anode ground beds were set up in area 2. The anode spacing of each ground bed was about 14 meters, and the anode ground bed was about 8 meters away from the pipeline. Each anode ground bed consisted of three anodes. The calculated potential distribution effect of all buried pipelines in the station is as follows. Figure 11 As shown.

[0030] After shallow-buried horizontal distributed anode ground beds were set up in areas 1 and 2 respectively, the buried pipelines in these areas received ideal cathodic protection.

[0031] S1005. Determine the design principles for cathodic protection in typical operating conditions: In some areas of the station, the buried pipelines are relatively isolated with few other structures around them, providing ample space for construction. As the distance between the auxiliary anode bed and the pipeline gradually increases, the cathodic protection range also gradually increases, but the anode output current also gradually increases. When using an auxiliary anode bed, with the anode distance from the pipeline being 5-8m, the protection range of a single anode group is approximately 16-22m.

[0032] S1006. Real-world case verification: Three power supply tests were conducted on an isolated pipeline area at a certain station. Ten MIMO anode tubes were used in the anode ground bed, 5 meters away from the pipeline, with output currents of 1.5A, 2A, and 2.5A respectively. This area has multiple grounding points, which shield the pipeline, limiting the protection distance to only 7-10 meters. As the output current increased, the protection potential at the same test location shifted negatively, increasing the effective protection distance of the pipeline.

[0033] S1007. Determine the precise design principles for typical operating conditions of cathodic protection in the station area: For isolated pipeline areas in the station, it is recommended to use shallow buried distributed auxiliary anode ground beds, with the distance between the anode and the pipeline being 5~8m, and the protection range of a single anode group being approximately 16~22m.
