Wherein the plurality of failure risk factors of the girth weld to be detected can be pre-stored. The failure risk factors can be obtained by the constructor looking up the pipeline attribute data, the pipeline installation construction record, the pipeline internal and external detection record, the geological disaster high-risk section record and other data, and then the failure risk factors of the girth joint to be detected are stored. The pipeline property data comprises data such as design pressure of a pipeline, running pressure of the pipeline, wall thickness of the pipeline and the like, the pipeline installation construction records comprise data such as a welding method between the two pipelines, the pipeline internal and external detection records comprise data such as an internal detection result and a ray negative result of the pipeline and the like, and the geological condition data of a region where a girth weld is located is recorded in a geological disaster high-risk section.
In addition, internal defect factors are used to indicate defects that are present inside the girth weld. Internal defect factors include radiographic results and internal inspection results. The load bearing factor refers to a factor influencing the load bearing capacity borne by the circumferential weld. The load bearing factors comprise the ratio of the operating pressure to the design pressure of the circumferential weld, the joint type of the circumferential weld, the stress concentration position of the circumferential weld, the repair port result of the circumferential weld and the like. The welding condition factor is used to indicate the actual welding condition of the girth weld.

The construction management factor is used for indicating the condition that a management party of the circumferential weld manages the circumferential weld. The construction management factors comprise the design conformity degree of two pipelines of the circumferential weld, the conformity degree between the detection time and the construction time of the circumferential weld, the operation level of a manager of the circumferential weld and the like.

The failure consequence coefficient of the area where the girth weld is located can be determined according to the corresponding relation between the area where the girth weld is located and the failure consequence coefficient. For example, table 1 shows a correspondence relationship between a region where a girth weld is located and a failure consequence coefficient, which is provided in the embodiment of the present application. As shown in Table 1, when the girth weld is in the non-high consequence region, the corresponding failure consequence coefficient is 1. When the girth weld is positioned in the fruit zone after the I-level stage, the corresponding failure consequence coefficient is 1.1. When the girth weld is positioned in a fruit area after the II-level fruit area, the corresponding failure consequence coefficient is 1.2. When the girth weld is positioned in a high-III rear fruit area, the corresponding failure consequence coefficient is 1.39.

The area of the circumferential weld can be determined according to chapter 6 of GB32167 oil and gas transmission pipeline integrity management Specification, and description thereof is omitted.
Step 103: and determining the failure risk value of the girth weld according to the multiple failure risk factors and the failure consequence coefficients of the girth weld.
The implementation mode of determining the failure risk value of the girth weld according to the multiple failure risk factors and the failure consequence coefficients of the girth weld can be as follows: and for a first failure risk factor in the failure risk factors, determining the corresponding possibility of the first failure risk factor according to the first failure risk factor, and determining the total failure possibility of the girth weld according to a plurality of possibilities corresponding to the failure risk factors one by one. And determining the failure risk value of the girth weld according to the total failure possibility and the failure consequence coefficient of the girth weld. The corresponding possibility of the first failure risk factor is used for indicating the possibility of the first failure risk factor inducing the girth weld failure, and the first failure risk factor is any one of the failure risk factors.
The first failure risk factors can be of various types, and when the types of the first failure risk factors are different, different implementation manners can be provided for determining the corresponding possibility of the first failure risk factors according to the first failure risk factors. Specifically, the first failure risk factor may be the following 5: internal defect factors, load bearing factors, welding condition factors, construction management factors, and environmental factors.
(1) When the first failure risk factor is an internal defect factor, according to the first failure risk factor, an implementation manner of determining a probability corresponding to the first failure risk factor may be: and determining the corresponding possibility of the internal defect factors according to the ray film result of the girth weld and the internal detection result of the girth weld.
Internal defects refer to bubbles in the girth weld, internal cracks, residues in the weld, and the like. The internal defects of the girth weld can be respectively determined according to the internal detection result of the girth weld and the ray negative result of the girth weld. Therefore, the corresponding possibility of the internal defect factor can be determined according to the ray film result of the girth weld and the internal detection result of the girth weld.
In a possible implementation manner, the determining the corresponding possibility of the internal defect factor according to the radiographic film result of the girth weld and the internal detection result of the girth weld may specifically be: determining a score corresponding to a radiographic film result of the circumferential weld according to the radiographic film result of the circumferential weld, determining a score corresponding to an internal detection result of the circumferential weld according to the internal detection result of the circumferential weld, and determining a probability corresponding to the internal defect factor according to the score corresponding to the radiographic film result of the circumferential weld and the score corresponding to the internal detection result of the circumferential weld.
Generally, when a welded pipe needs to be inspected after the pipe welding construction is finished, the girth weld is irradiated with X-rays, and after the girth weld is irradiated with the X-rays, a radiograph after the X-rays are irradiated is obtained. When the internal defects of the girth weld are different, the ray negative results are also different, and when the ray negative results are different, the corresponding scores of the ray negative results are also different. Therefore, in the embodiment of the present application, an implementation manner of determining the score corresponding to the negative result of the circumferential weld according to the negative result of the circumferential weld may be: and determining the score corresponding to the ray film result of the girth weld according to the corresponding relation between the ray film result of the girth weld and the score of the ray film result of the girth weld.
For example, table 2 shows the correspondence between the radiographic results of the girth welds and the scores of the radiographic results of the girth welds provided in the embodiments of the present application. Generally, when a girth weld is irradiated with X-rays, the internal defects of the girth weld are different, the radiograph results are also different, and the radiograph results can be expressed by radiograph grades. As shown in Table 2, when the radiograph is the I-stage radiograph, the radiograph result corresponds to a score of 0. When the radiograph is a level II radiograph, the radiograph result corresponds to a score of 30. When the radiograph is grade III, the radiograph result corresponds to a score of 75. When the radiograph is an IV grade radiograph, the score corresponding to the radiograph result is 100. When there is no radiograph result, the corresponding score for the radiograph result is 50. Wherein a higher grade for the radiograph indicates a more severe internal defect of the girth weld.

Figure BDA0002349543700000101
In addition, during the operation of the pipeline, the circumferential weld sometimes needs to be internally detected to determine the internal defects of the circumferential weld. When the internal detection is carried out on the circumferential weld, the internal detector is used for detecting the internal defects of the circumferential weld. The internal defect degrees of the circumferential weld are different, and the corresponding scores of the internal detection results are also different. Therefore, in the embodiment of the present application, an implementation manner of determining a score corresponding to a corresponding inner detection result according to the inner detection result of the girth weld may be: and determining the score corresponding to the internal detection result of the girth weld according to the corresponding relation between the internal defect result of the girth weld and the score of the internal detection result.
For example, table 3 shows the correspondence between the internal defect result of the girth weld and the score of the internal detection result provided in the embodiment of the present application. As shown in table 3, when the internal detection identifies that the girth weld is not defective, the score corresponding to the internal detection result is 0. When the internal detection identifies the slight defect of the girth weld, the corresponding score of the internal detection result is 15. When the internal detection identifies the medium defects of the girth weld, the corresponding score of the internal detection result is 30. When the severe defects of the girth weld are identified by internal detection, the corresponding score of the internal detection result is 50.
TABLE 3
Internal test results Score corresponding to internal detection result
Internal detection and identification of defect-free girth weld 0
Internal detection and identification of slight defects of circumferential weld 15
Internal detection and identification of medium defects of circumferential weld 30
Internal detection and identification of severe defects of circumferential weld 50
In addition, according to the score corresponding to the radiographic film result of the circumferential weld and the score corresponding to the internal detection result of the circumferential weld, the implementation manner of determining the probability corresponding to the internal defect factor may be: and adding the score corresponding to the ray film result of the girth weld and the score corresponding to the internal detection result of the girth weld, and taking the obtained result as the probability corresponding to the internal defect factor. Optionally, the score corresponding to the radiographic result of the girth weld may be multiplied by the score corresponding to the internal detection result of the girth weld, and the obtained result may be used as the probability corresponding to the internal defect factor. Of course, there may be other implementation manners for determining the probability corresponding to the internal defect factor according to the score corresponding to the radiographic film result of the circumferential weld and the score corresponding to the internal detection result of the circumferential weld, and the embodiment of the present application is not limited herein.
(2) When the first failure risk factor is a load bearing factor, according to the first failure risk factor, an implementation manner of determining a probability corresponding to the first failure risk factor may be: and acquiring the ratio of the operating pressure to the design pressure of the circumferential weld, the joint type of the circumferential weld, the stress concentration position of the circumferential weld and the repair opening result of the circumferential weld.

It should be noted that in all the tables above, the score set for each failure risk factor represents the likelihood that the factor may cause failure of the girth weld. A greater score for a factor indicates a greater likelihood that the factor may cause the girth weld to fail.
In addition, in a possible implementation manner, the determining the total failure probability of the girth weld according to a plurality of probabilities corresponding to a plurality of failure risk factors one to one may specifically be: and adding a plurality of probability degrees corresponding to the failure risk factors one by one, and taking the obtained result as the total failure probability degree of the girth weld.
For example, among the failure risk factors of the girth weld, the internal defect factor corresponds to a probability of 60, the load factor corresponds to a probability of 70, the welding condition factor corresponds to a probability of 78, the construction management factor corresponds to a probability of 70, and the environmental factor corresponds to a probability of 0. Adding the likelihood 60 corresponding to the internal defect factor, the likelihood 70 corresponding to the load bearing factor, the likelihood 78 corresponding to the welding condition factor, the likelihood 70 corresponding to the construction management factor and the likelihood 0 corresponding to the environmental factor to obtain a result 278 as a total failure likelihood of the girth weld.
Optionally, determining the total failure probability of the girth weld according to a plurality of probabilities corresponding to the plurality of failure risk factors one-to-one may further include: and each failure risk factor in the failure risk factors corresponds to a weight value one by one, the probability corresponding to each failure risk factor is multiplied by the corresponding weight value, then the values obtained after the probability corresponding to each failure risk factor is multiplied by the weight value are added, and the obtained result is used as the total failure probability of the girth weld.
For example, the internal defect factor of the failure risk factors of the girth weld corresponds to a probability of 60, and the internal defect factor corresponds to a weight value of 15%. The load factor corresponds to a probability of 70, and the load factor corresponds to a weight of 20%. The welding condition factor corresponds to a probability of 78, and the welding condition factor corresponds to a weight of 15%. The construction management factor corresponds to a probability of 70, and the weight value of the construction management factor is 20%. The probability corresponding to the environmental factor is 0, and the weight value corresponding to the environmental factor is 30%. The likelihood 60 corresponding to the internal defect factor is multiplied by the weight value 15% corresponding to the internal defect factor, resulting in 9. The probability 70 corresponding to the load factor is multiplied by the weight value 20% corresponding to the load factor, and the result is 14. The probability 78 corresponding to the welding condition factor is multiplied by the weight value 15% corresponding to the welding condition factor, and the result is 11.7. The result of multiplying the probability 70 corresponding to the construction management factor by the weight value 20% corresponding to the construction management factor is 14. The probability 0 corresponding to the environmental factor is multiplied by the weight value 30% corresponding to the environmental factor, and the result is 0. Adding a result 9 obtained by multiplying the possibility degree corresponding to the internal defect factor by the weight value corresponding to the internal defect factor, a result 14 obtained by multiplying the possibility degree corresponding to the load bearing factor by the weight value corresponding to the load bearing factor, a result 11.7 obtained by multiplying the possibility degree corresponding to the welding condition by the weight value corresponding to the welding condition, a result 14 obtained by multiplying the possibility degree corresponding to the construction management factor by the weight value corresponding to the construction management factor, and a result 0 obtained by multiplying the weight value corresponding to the environmental factor by the weight value corresponding to the environmental factor to obtain a result 48.7 serving as the total failure possibility degree of the girth weld.
In addition, in a possible implementation manner, determining the failure risk value of the girth weld according to the total failure probability and the failure consequence coefficient of the girth weld may specifically be: and multiplying the total failure possibility degree of the girth welding seam by the failure consequence coefficient, and taking the obtained result as the risk value of the girth welding seam.
For example, the total failure probability of the girth weld is 278, the failure consequence coefficient is 1, and the total failure probability 278 of the girth weld is multiplied by the failure consequence coefficient 1, and the obtained result 278 is used as the risk value of the girth weld.
In addition, in practice, the girth welds to be detected may be girth welds with a large failure risk, and for the girth welds, the failure risk values of the girth welds can be directly set to fixed values. The girth weld with a high failure risk refers to any one of three conditions that the girth weld is a suspected black girth weld, the grade of a ray negative of the girth weld is greater than a reference grade, and the area where the girth weld is located is a natural disaster geological area.
Therefore, in the embodiment of the application, before the failure consequence coefficient of the area where the girth weld is located is obtained, whether the girth weld is a suspected black girth weld, whether the ray negative of the girth weld is greater than the reference grade, and whether the geological condition of the area where the girth weld is located is a natural disaster geological area can be determined according to a plurality of failure risk factors of the girth weld. And if the girth weld is a suspected black girth weld, the grade of the ray negative of the girth weld is greater than the reference grade, and the area where the girth weld is located is any one of the three conditions of a natural disaster geological area, directly determining the risk value of the girth weld as a fixed value. If the girth weld is not the suspected black girth weld, the grade of the ray negative of the girth weld is less than the reference grade, and the area where the girth weld is located is not the natural disaster geological area, at the moment, the step of obtaining the failure consequence coefficient of the area where the girth weld is located needs to be executed. The fixed value may be 380, 390, 400, etc., and the embodiment of the present application is not limited herein. The girth weld with the suspected black opening refers to the girth weld with the detection record but no construction record.
Wherein the reference grade of the negative of the girth weld may be grade iii. Of course, other levels are also possible, and the embodiments of the present application are not limited herein. The fact that the area where the girth weld is located is not the natural disaster area means that the area where the girth weld is located cannot have natural disasters, and protective measures meeting requirements are provided. The area where the girth weld is located is a natural disaster area, which means that the area where the girth weld is located can have natural disasters and has no protective measures meeting the requirements. The natural disasters refer to serious geological disasters such as landslides, unstable slopes and unstable slopes.
In addition, in practice, in order to facilitate the constructors to evaluate the risk of the circumferential weld in a targeted manner and make reasonable treatment measures, the corresponding treatment measures can be determined according to the risk value of the circumferential weld. The implementation mode of determining the corresponding treatment measures according to the risk value of the girth weld can be as follows: after failure risk values of the plurality of girth welds are determined, the risk level of each girth weld in the plurality of girth welds is determined according to the corresponding relation between the risk value interval and the risk level. And searching a girth weld with the risk grade larger than or equal to the reference risk grade from the plurality of girth welds. And determining the core failure risk factors according to the found multiple failure risk factors of each circumferential weld in the circumferential welds. And determining a maintenance strategy aiming at the areas where the plurality of girth welds are located according to the core failure risk factors.
The implementation manner of determining the risk level of each circumferential weld of the plurality of circumferential welds according to the corresponding relationship between the risk value interval and the risk level may be: and determining a risk value interval where the risk value of any girth weld is located, and searching the risk grade corresponding to the risk value interval in the corresponding relation between the risk value interval and the risk grade.
For example, table 13 is a corresponding relationship between a risk value interval and a risk level provided in the embodiment of the present application. As shown in Table 13, when the risk value interval is 0-80, the corresponding risk level is class I. And when the risk value interval is 81-160, the corresponding risk grade is II grade. When the risk value interval is 161-240, the corresponding risk grade is grade III. When the risk value interval is 241-320, the corresponding risk grade is IV grade. When the risk value interval is 321-400, the corresponding risk grade is V grade. Wherein a higher risk rating indicates a greater likelihood of failure of the girth weld.

Interval of risk value Risk rating
0~80 Class I
81~160 Stage II
161~240 Class III
241~320 IV stage
321~400 Class V
In addition, the search for a girth weld with a risk level greater than or equal to the reference risk level from among the plurality of girth welds may be implemented by: and determining a risk value interval of the girth weld in the corresponding relation between the risk value interval and the risk grade according to the risk value of each girth weld in the plurality of girth welds, and determining the risk grade of the girth weld according to the determined risk value interval. And selecting the girth welds with the risk grade larger than or equal to the reference risk grade from the risk grade corresponding to each girth weld.
In addition, according to the found multiple failure risk factors of each girth weld in the girth weld, the implementation mode for determining the core failure risk factors can be as follows: determining the corresponding possibility of the multiple failure risk factors of each girth weld, and taking the failure risk factor corresponding to the maximum possibility as the core failure risk factor.
For example, the plurality of failure risk factors of the girth weld include internal defect factors, load bearing factors, welding condition factors, construction management factors, and environmental factors. The internal defect factor corresponds to a probability of 105. The load factor corresponds to a probability of 50. The welding condition factor corresponds to a probability of 108.
