Description

Method and device for judging interaction influence of pipeline defects
Technical Field
The invention relates to the technical field of petroleum and natural gas pipelines, in particular to a method and a device for judging interactive influence of pipeline defects.
Background
At present, the inner detection is the most effective method for grasping the safety state of the pipeline, and various defects of the pipeline body, including corrosion defects, pits, weld defects, manufacturing defects and the like, can be found by carrying out the inner detection on the long-distance pipeline.
When the internal detection operation is usually carried out once, the detection party can sequentially adopt two detectors, namely the magnetic flux leakage internal detector and the geometric deformation detector, to detect the metal loss defect and the deformation defect of the pipeline respectively. Since the geometric deformation detection and the magnetic leakage detection are carried out independently, thousands of pieces of concave data and metal loss defect data detected by the two detectors are independent of each other, that is, if one defect on a pipeline has both metal loss and concave, only two independent defects, namely, metal loss and concave, can be detected by the current internal detection technology, and the detected two independent defects are generally evaluated in the form of a single defect and a maintenance decision is made, so that the composite defect is missed in the detection and evaluation process, and the composite defect is processed by adopting common evaluation and maintenance criteria. And the threat of composite defects such as pits on girth welds, corrosion defects containing pits, corrosion-containing weld defects and the like to the safety performance of pipelines far exceeds the common defects.
At present, in research and development of an internal detector, some students at home and abroad make research and attempt of a composite defect detection technology, but under the condition that existing magnetic leakage detection and deformation detection are respectively carried out, no related result is seen for judging whether a composite defect exists in a pipe body.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The invention provides a method for judging the interaction influence of pipeline defects, which can judge the interaction influence of the pipeline defects according to detected various defect data, so that omission of composite defect analysis of the pipeline caused by separation of the various defect data of the pipeline can be avoided. The method for judging the interactive influence of the pipeline defects provided by the invention is explained in detail by a specific embodiment.
An embodiment of the present invention provides a method for judging the interaction effect of a pipe defect, referring to fig. 1, the method includes the following steps:
Step 101, acquiring girth weld data and defect data of a pipeline, wherein the girth weld data comprises girth weld mileage and girth weld numbers, and the defect data comprises mileage L, girth weld numbers, length L, width w, circumferential distribution O and positions of defects, and distance L up from an upstream girth weld and length L 0 of a pipe joint.
In the step, various defects and girth weld detection data of the pipeline are extracted according to the detection result in the pipeline. The girth weld data comprises girth weld mileage and girth weld numbers, and the defect data comprises a mileage L of the defect, a girth weld number of the defect, a length L of the defect, a width w of the defect, circumferential distribution O of the defect, positions of the defect (metal loss, inner/outer), a distance L up from an upstream girth weld and a length L 0 of a pipe joint of the defect.
And 102, judging the interaction influence of the pipeline defect and the girth weld according to the girth weld data and the defect data, and/or judging the interaction influence of the pipeline compound defect according to the girth weld data and the defect data.
In this step, the composite defect of the pipeline is a composite defect formed by any two defects on the pipeline, such as a composite defect of a dent and a metal loss, a composite defect of a dent and a weld defect, a composite defect of a metal loss and a weld defect, and the like.
In this step, two kinds of interactive influence judgment are included:
the first category is that the interaction influence of the pipeline defect and the girth weld is judged, namely whether the pipeline defect is positioned on the girth weld is judged.
The second type is that judging the interaction influence of the compound defect of the pipeline, namely judging whether the pipeline has the compound defect or not.
As can be seen from the above description, the method for judging the interactive influence of the pipeline defect provided in this embodiment firstly obtains girth weld data and defect data of the pipeline, then judges the interactive influence of the pipeline defect and the girth weld according to the girth weld data and the defect data, and/or judges the interactive influence of the pipeline compound defect according to the girth weld data and the defect data. Therefore, the method for judging the interactive influence of the pipeline defects can judge the interactive influence of various defects of the pipeline, so that omission of composite defects of the pipeline when a professional evaluator analyzes the data of different types of defects of the pipeline can be avoided.
In a preferred embodiment, the determination of the first type of interaction (interaction of pipe defects with girth weld) specifically comprises:
S11, obtaining the distance L up between each defect and an upstream girth weld, and calculating the distance between the defect and a downstream girth weld as follows:
Ldown＝L0-l-Lup
wherein L 0、l、Lup units are m;
s12, acquiring the distance L min,Lmin＝min(|Lup|,Ldown between each defect and the nearest girth weld;
S13, judging the distance L min between the defect and the nearest girth weld and the size of a weld affected area a, wherein the size of the weld affected area a is generally 0.2m, if L min is larger than a, the defect does not have interaction effect with the girth weld, and if L min is smaller than or equal to a, the defect has interaction effect with the girth weld or is located on the girth weld.
It should be noted that the defect may be a dent defect or a metal loss defect, and when it is determined that the defect has an interaction with the girth weld or is located on the girth weld, the defect proves to be more serious in terms of security threat to the pipeline, so that a more strict and conservative evaluation criterion is adopted.
In a preferred embodiment, the determination of the second type of interaction effect (pipe composite defect interaction effect) is specifically implemented by the following manner, that is, the step of determining whether the pipe has a composite defect includes:
S21, for any composite defect, acquiring two types of defect data in the composite defect, taking one type of defect with a small number of defects in the two types of defects as a judging standard A, and the other type of defect as B, for example, on a pipeline, the number of pits is generally small, the number of metal losses is large, and for the composite defect judgment of pits and metal losses, each pit is taken as a standard.
S22, determining whether each A-type defect has a defect B or not, wherein the method comprises the following steps:
Taking a first defect A1 of A class, and acquiring mileage L A1, length L A1, width w A1 and circumferential distribution O A1 of A1;
judging whether the area of the defect A1 has B type defects or not, namely, judging whether the length L Bx, the width w Bx, the mileage L Bx and the circumferential distribution O Bx of the B type defects simultaneously meet the following two conditions of a and B:
a. the two defects are crossed in the axial direction, namely:
l Bx-1/2*lBx<LA1+1/2*lA1 and L Bx+1/2*lBx>LA1-1/2*lA1
B. the two defects are crossed in the circumferential direction, namely:
O Bx-360*wBx/πD<OA1+360*wA1/pi D and O Bx+360*wBx/πD>OA1-360*wA1/pi D
If the mileage and circumferential distribution of the defect Bx belongs to the area region of the defect A1, the defect Bx and the defect A1 are compound defects.
Further, the composite defect consisting of the defects Bx and A1 has a mileage of L A1, a circumferential distribution of O A1, and a length L A1Bx and a width w A1Bx according to the following relationship:
lA1Bx＝max(LBx+1/2*lBx,LA1+1/2*lA1)-min(LBx-1/2*lBx,LA1-1/2*lA1)
wA1Bx＝πD/180*{max(OBx+360*wBx/πD,OA1+360*wA1
/πD)-min(OBx-360*wBx/πD,OA1-360*wA1/πD)}
in the above formulas, the units of defect mileage, length and width are all m, and the circumferential distribution unit is converted into min (minutes).
Further, in step S22, when judging whether the area of the defect A1 has the B type defects one by one, firstly sorting the B type defects according to the mileage from small to large, and when judging the mileage L Bx>LA1+1/2*lA1 of the x type defect, indicating that the A1 defect has no combined defect, and directly searching the combined defect of the defect A2 without continuously searching in the B type defect.
As can be seen from the above description, in this embodiment, first, some kind of defects, such as pits, metal loss, weld defects, spiral weld and longitudinal weld defects, are found out in the detection result in the pipeline, then the detection data of the circumferential weld in the detection result in the pipeline are found out, then whether the defects are located on the circumferential weld is judged, and the interactive influence of the compound defects is judged, which mainly includes judging whether the compound defects of two types of defects exist, such as the compound defects of pits and metal loss, the compound defects of pits and weld defects, the compound defects of metal loss and weld defects, and finally the compound defect size is recalculated according to the defect size. Therefore, the method for judging the interactive influence of the pipeline defects can judge the interactive influence of various defects of the pipeline, so that omission of composite defects of the pipeline when a professional evaluator analyzes the composite defects due to independence of different types of defect data of the pipeline can be avoided.
