[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Figure 1 is a flow chart of the steps of a pipeline risk assessment method provided by an embodiment of the present invention, such as Figure 1 As shown, the method may include:

[0046] Step 101: Determine a pipeline risk index based on a pipeline construction score, a pipeline management score, a pipeline score, and an environmental score corresponding to a target pipeline.

[0047] In the embodiment of the present invention, as the service life of the pipeline increases, factors such as aging and corrosion of the pipeline material and changes in the external environment may cause the pipeline condition to gradually deteriorate, thereby increasing the risk of accidents. As an important means of preventing accidents, risk assessment of pipelines can timely discover and eliminate potential safety hazards and ensure the property safety and environmental safety of users.

[0048] For the pre-laid target pipeline, the integrity of the pipeline can be evaluated from different dimensions, thereby realizing the assessment of the risk of the target pipeline. Based on the entire life cycle of the pipeline, including the entire process from pipeline design, construction (including material procurement, construction, etc.), operation, maintenance, supervision, to final abandonment, demolition or renovation, the pipeline data of the target pipeline at different process stages is obtained, and the corresponding scores are calculated based on different pipeline data to obtain scoring data of different dimensions. Specifically, the pipeline management information, construction information, pipeline information, environmental information of the target pipeline and other information can be obtained. In addition, the pipeline management score can be determined based on the pipeline management information, the pipeline construction score can be determined based on the construction information, the pipeline management score can be determined based on the pipeline information, and the environmental score can be determined based on the environmental information.

[0049] Among them, pipeline management information may include daily management information, pipeline inspection information, daily maintenance information and perimeter protection information. Specifically, daily management information may include the completeness of operating procedures for the target pipeline, emergency plans and drills, personnel training, personnel position management, maintenance plan execution, data and information management, etc. Pipeline inspection information may include historical inspection information for the target pipeline, daily maintenance information may include historical maintenance information for periodic maintenance of the target pipeline, and perimeter protection information may include ground signs set around the target pipeline, public education information for safety education for surrounding personnel, etc. Construction information may include construction status information and completion status information. Construction status information may include pipeline burial depth information and backfill record information. Completion status information may include the activity level above the pipeline (for example, the pipeline is in a location with high traffic flow, the pipeline is in an area with low human flow), pipeline-related occupancy, etc. The pipeline information may include the pipeline quality information, interface quality information, service life information, corrosion protection information and operation safety margin of the target pipeline. The pipeline quality information may include the quality of the pipe material, the interface quality may include the quality of the interface used to connect different pipe sections, the service life information may include the service life of the target pipeline, the corrosion protection information may include the medium corrosivity of the medium in the target pipeline, the internal corrosion protection information of the target pipeline, the soil corrosivity information of the target pipeline, the cathodic protection potential information of the target pipeline, the cathodic protection potential detection of the target pipeline, the constant potentiostat information of the target pipeline, the stray current interference of the target pipeline, the anti-corrosion layer quality information of the target pipeline, the anti-corrosion layer detection information of the target pipeline, etc. The operation safety margin may include the safety margin between the parameters such as the pressure and temperature of the target pipeline and the design value. The environmental information may include the pipeline laying environment of the target pipeline and the status information of the environmental organisms corresponding to the target pipeline (such as the distribution of deep-rooted plants, biological invasion, etc.).

[0050] Correspondingly, the pipeline construction score is determined based on the construction status information and completion status information of the target pipeline; the pipeline management score is determined based on the daily management information, pipeline inspection information, daily maintenance information and surrounding protection information of the target pipeline; the pipeline score is determined based on the pipeline quality information, interface quality information, service life information, corrosion protection information and operation safety margin of the target pipeline; the pipeline environment score is determined based on the pipeline laying environment of the target pipeline and the state information of the environmental organisms corresponding to the target pipeline. Exemplarily, based on the different data items collected, each data item can be quantified based on the preset rules, and the pipeline construction score, pipeline management score, pipeline score and environmental score can be obtained by calculation. For example, for the pipeline environment score, a score can be given according to the comprehensiveness of the pipeline laying environment around the target pipeline. At the same time, based on the distribution of deep-rooted plants around the target pipeline and the biological invasion, the corresponding score is determined, and the two scores are added to obtain the pipeline environment score. Among them, the rules for quantifying different data items can be set according to the actual development situation, and the embodiment of the present invention does not limit this.

[0051] Based on the pipeline construction score, pipeline management score, pipeline score and environmental score corresponding to the target pipeline, the pipeline risk index is determined. Among them, the pipeline construction score, pipeline management score, pipeline score, environmental score and pipeline risk index can be expressed in numbers. For example, the value range of the pipeline construction score, pipeline management score, pipeline score and environmental score can be a number from 0 to 100, and correspondingly, the value range of the pipeline risk index can be a number from 0 to 400. The pipeline risk index is used to characterize the possibility of risk in the target pipeline. Through multiple data of different dimensions, the state of the target pipeline is evaluated from different dimensions, and then the possibility of an accident in the target pipeline is determined. The size of the pipeline risk index can be negatively correlated with the possibility of risk in the target pipeline. For example, the larger the value of the pipeline risk index, the smaller the possibility of risk in the target pipeline; the smaller the value of the pipeline risk index, the greater the possibility of risk in the target pipeline.

[0052] Alternatively, the pipeline risk index can be calculated by the first formula:

[0053] P=P1+P2+P3+P4

[0054] Among them, P is used to characterize the pipeline risk index, P1 is used to characterize the pipeline construction score, P2 is used to represent the pipeline management score, P3 is used to characterize the pipeline score, and P4 is used to characterize the environmental score. It can be understood that the embodiment of the present invention calculates the pipeline risk index based on the scores of four dimensions. When the pipeline risk index is calculated based on the scores of other dimensions, P = P1 + P2 + ... + Pn, where n is the number of scores of different dimensions. The present invention does not limit the selection and number of scoring dimensions.

[0055] In a possible implementation, the calculation dimensions corresponding to the pipeline risk index can also be divided into the following contents:

[0056] Dimension 1: Third-party damage: burial depth, backfill records, ground markings, activity level above the pipeline, occupation conditions, line inspections, public education, economic development level, etc.

[0057] Dimension 2: Inherent factors of the pipeline itself: pipe quality, interface quality, operating safety margin, etc.

[0058] Dimension 3, pipeline corrosion: service life, medium corrosivity, internal corrosion protection, soil corrosivity, cathodic protection potential, cathodic protection potential detection, constant potentiostat, stray current interference, anti-corrosion layer quality, anti-corrosion layer detection, comprehensive inspection, cathodic protection current, etc.

[0059] Dimension 4, other misoperations: the possibility of reaching the maximum allowable working pressure, operating procedures, emergency plans and drills, training, job management, maintenance plan execution, data and information management, etc.

[0060] Dimension 5: Pipeline service environment: pipeline laying environment, deep-rooted plant distribution, biological invasion, etc.

[0061] It can be understood that the above-mentioned dimensional division and the specific content contained in each dimension are only for example, and the specific dimensional division and the specific content contained in each dimension can be set according to actual needs, and the embodiment of the present invention does not limit this.

[0062] Step 102: Determine a risk consequence index based on the medium hazard score, population density score, pipeline interruption impact score, and leakage diffusion impact coefficient corresponding to the target pipeline.

[0063] In an embodiment of the present invention, based on the specific medium corresponding to the medium inside the target pipeline, the medium hazard score corresponding to the medium is determined. For example, the medium inside the pipeline may include methane, ethane and hydrogen sulfide. Accordingly, assuming that the medium hazard is ranked from large to small as hydrogen sulfide, methane and ethane, it can be obtained that the medium hazard score of hydrogen sulfide is greater than the medium hazard score of methane, and the medium hazard score of methane is greater than the medium hazard score of ethane. Based on the population density information around the pipeline, the population density score is determined. For example, when the population density is larger, the population density score can be higher; when the population density is smaller, the population density score is lower. Scoring is performed based on the impact of the interruption of the target pipeline. For example, the pipeline interruption impact score can be determined based on the importance of the target pipeline. Assuming that the target pipeline is a city main pipeline, the pipeline interruption impact score is larger, and when the target pipeline is a branch pipeline, the pipeline interruption impact score is smaller. Based on the pipeline gas leakage value, the leakage diffusion impact coefficient is determined. For example, the pipeline gas leakage value is different according to the medium and operating pressure. Based on the pipeline gas leakage value, the leakage diffusion influence coefficient can be determined by interpolation calculation, for example, the corresponding relationship between different pipeline gas leakage values ​​and leakage diffusion influence coefficients is determined in advance, and after the pipeline gas leakage value is determined, the leakage diffusion influence coefficient is determined based on the corresponding relationship. For example, when the pipeline gas leakage value is 14370, the leakage diffusion influence coefficient is 6; when the pipeline gas leakage value is 13357, the leakage diffusion influence coefficient is 5.5; when the pipeline gas leakage value is 12412, the leakage diffusion influence coefficient is 5.1.

[0064] The pipeline gas leakage value can be calculated based on the following formula:

[0065] S=(d 2 ×p) 1 / 2 ×MW×0.474

[0066] Among them, S is used to indicate the pipeline gas leakage value; d is used to indicate the diameter of the target pipeline, mm; p is used to indicate the operating pressure of the target pipeline, MPa; MW is used to indicate the molecular weight of the medium.

[0067] Based on the medium hazard score, population density score, pipeline interruption impact score, and leakage diffusion impact coefficient corresponding to the target pipeline, the risk consequence index is determined. Among them, the risk consequence index can be used to characterize the degree of adverse impact caused by the risk if the target pipeline has a risk. The risk consequence index is positively correlated with the degree of adverse impact caused by the risk, that is, the larger the risk consequence index, the higher the degree of adverse impact caused by the risk; the smaller the risk consequence index, the lower the degree of adverse impact caused by the risk.

[0068] Optionally, the risk consequence indicator may be calculated based on a second formula, which may be as follows:

[0069] C=C1×(C2+C3)×C4

[0070] Among them, C is used to characterize the pipeline risk consequence index, C1 is used to characterize the medium hazard score, C2 is used to characterize the population density score, C3 is used to characterize the pipeline interruption impact score, and C4 is used to characterize the leakage diffusion impact coefficient.

[0071] Step 103: Determine a target risk value corresponding to the target pipeline based on the pipeline risk indicator and the pipeline risk consequence indicator.

[0072] In an embodiment of the present invention, a target risk value corresponding to a target pipeline is determined based on a pipeline risk index and a pipeline risk consequence index. The target risk value is used to characterize the actual possibility and severity of a safety hazard in the target pipeline. The smaller the target risk value, the higher the actual possibility and severity of a safety hazard in the target pipeline; the larger the target risk value, the lower the actual possibility and severity of a safety hazard in the target pipeline.

[0073] Optionally, step 103 may include the following steps:

[0074] Step 201: Determine a target risk value corresponding to the target pipeline based on a target formula, the pipeline risk index, and the pipeline risk consequence index.

[0075] In the embodiment of the present invention, the pipeline risk index and the pipeline risk consequence index may be calculated based on the target formula to obtain a target risk value corresponding to the target pipeline.

[0076] Exemplarily, the target formula may include:

[0077]

[0078] Among them, the R is used to characterize the target risk value, the P is used to characterize the pipeline risk index, the C is used to characterize the pipeline risk consequence index, the P1 is used to characterize the pipeline construction score, the P2 is used to represent the pipeline management score, the P3 is used to characterize the pipeline score, the P4 is used to characterize the environmental score, the C1 is used to characterize the medium hazard score, the C2 is used to characterize the population density score, the C3 is used to characterize the pipeline interruption impact score, and the C4 is used to characterize the leakage diffusion impact coefficient.

[0079] It is understandable that the calculation method of the target risk value R, the pipeline risk index P and the pipeline risk consequence index C can be set according to actual needs and the actual situation of the target pipeline, and the embodiment of the present invention does not limit this.

[0080] In summary, in the embodiment of the present invention, the pipeline risk index is determined based on the pipeline construction score, pipeline management score, pipeline score and environmental score corresponding to the target pipeline; the risk consequence index is determined based on the medium hazard score, population density score, pipeline interruption impact score and leakage diffusion impact coefficient corresponding to the target pipeline; the target risk value corresponding to the target pipeline is determined based on the pipeline risk index and the pipeline risk consequence index. In this way, the pipeline risk index is determined by the score corresponding to the whole life cycle process of the target pipeline, so that the content represented by the pipeline risk index is richer and more comprehensive, and the comprehensiveness and accuracy of the pipeline risk index are improved to a certain extent. Correspondingly, the risk consequence index is determined based on the medium hazard score, population density score, pipeline interruption impact score and leakage diffusion impact coefficient corresponding to the target pipeline, so that the content represented by the risk consequence index is richer and more comprehensive, and the comprehensiveness and accuracy of the risk consequence index are improved to a certain extent. Further, based on the pipeline risk index and the risk consequence index, the target risk value corresponding to the target pipeline is determined, and the risk assessment of the target pipeline can be performed based on two dimensions, namely, pipeline risk and risk consequence, thereby improving the accuracy of the target risk value, avoiding erroneous risk warnings, improving the safety and reliability of pipeline use, and thus reducing the risk of safety accidents.

[0081] Optionally, the embodiment of the present invention may further include the following steps:

[0082] Step 301: Determine a pipeline treatment plan for the target pipeline based on the target risk value.

[0083] In an embodiment of the present invention, a pipeline treatment plan for the target pipeline is determined based on the target risk value. Since the higher the target risk value, the lower the possibility and severity of the safety hazard in the target pipeline, the target risk value can be divided into a threshold range, and different types of pipeline treatment plans can be set for different ranges. Exemplarily, when the target risk value is greater than a, the pipeline treatment plan can be set as a pipeline daily maintenance plan; when the target risk value is less than a and greater than b, the pipeline treatment plan can be set as a pipeline fault troubleshooting plan; when the target risk value is less than b, the pipeline treatment plan can be set as a pipeline fault determination and disposal plan. Wherein, a is greater than b.

[0084] In actual use, each time relevant pipeline processing solutions are pushed to users, after users process based on the pipeline processing solutions, user feedback information can be obtained and the feedback information can be collected and organized. In this way, after a period of use, a review can be conducted based on the overall feedback from users, and relevant information can be pushed to the administrator, so that the administrator can clearly identify product defects to determine whether the product needs to be adjusted, and relevant information can be pushed at the same time to upgrade the pipeline risk assessment method. Specifically, taking pipeline weld defects as an example: after the pipeline integrity product has been in operation for a period of time, the risk assessment and identification times for pipeline welds can be automatically counted, and corresponding user feedback can be obtained; based on user feedback, it can be clear whether the pipeline weld risk identification is accurate. In the case of inaccurate pipeline weld risk identification, analysis can be conducted based on the industry knowledge base and user feedback, and targeted modification suggestions can be given to users. For example, modification suggestions can be changes in data dimensions or adjustments to evaluation criteria.
