Description

Technical Field

[0001] This invention relates to the field of suspended pipeline technology, and in particular to a risk warning method, device, equipment and medium for suspended oil and gas pipelines. Background Technology

[0002] Oil and gas pipelines are typically buried underground or supported by structures. However, natural or human factors, such as water erosion and geological disasters, can cause the loss of soil support beneath the pipeline, leading to it becoming suspended. This poses a significant structural safety hazard, and the media transported within further amplifies the risk. The suspended section of the pipeline, under its own weight, the weight of the media, and external loads such as water pressure, can cause permanent bending and denting, potentially leading to fracture and fatigue failure. Furthermore, structural damage to the suspended section can result in leakage of the transported media, triggering a chain reaction of hazards. This not only disrupts the pipeline's energy supply but also causes environmental pollution. Moreover, the difficulty of repairs prolongs the pipeline's downtime, increasing losses. Therefore, proactively identifying and assessing the risk status of suspended pipelines, and implementing risk control measures when high risks are identified, allows for effective and precise intervention, preventing losses at minimal cost. Existing technologies typically focus on analyzing internal defects in oil and gas pipelines or using laboratory simulations to model the safety risks of suspended oil and gas pipelines in order to evaluate them. However, these methods usually consider pipeline corrosion and do not take into account the actual analysis of suspended oil and gas pipelines under the main test conditions, making it impossible to provide real-time risk warnings for suspended oil and gas pipelines. Summary of the Invention

[0003] This invention provides a risk warning method, device, equipment, and medium for suspended oil and gas pipelines, in order to solve the technical problem that existing technologies cannot provide real-time risk warnings for suspended oil and gas pipelines.

The maximum combined bending moment is identified based on the first directional load and the second directional load, and the maximum combined bending moment is determined. Risk warning information for the target oil and gas pipeline is determined based on the pipeline parameters and the maximum combined bending moment, and risk alerts are issued based on the risk warning information.

[0005] According to another aspect of the present invention, a risk warning device for suspended oil and gas pipelines is provided, comprising: The risk detection module is used to collect the suspension parameters and pipeline parameters of the target oil and gas pipeline when an overhanging target oil and gas pipeline is detected. The pipeline load analysis module is used to calculate the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters, respectively. The pipeline bending moment analysis module is used to identify the maximum combined bending moment based on the first directional load and the second directional load, and to determine the maximum combined bending moment. The risk warning module is used to determine the risk warning information of the target oil and gas pipeline based on the pipeline parameters and the maximum combined bending moment, and to provide risk alerts based on the risk warning information.

[0006] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising: At least one processor; and A memory communicatively connected to the at least one processor; wherein, The memory stores a computer program that can be executed by the at least one processor, which enables the at least one processor to perform the risk warning method for suspended oil and gas pipelines according to any embodiment of the present invention.

[0008] The technical solution of this invention, when a suspended target oil and gas pipeline is detected, collects the suspension parameters and pipeline parameters of the target oil and gas pipeline. Upon identification of a suspended oil and gas pipeline, relevant parameters of the current oil and gas pipeline are acquired in real time for real-time risk analysis. Based on the suspension parameters and pipeline parameters, a first-direction load in a first direction and a second-direction load in a second direction are calculated for the target oil and gas pipeline. The maximum combined bending moment is identified based on the first-direction load and the second-direction load. By calculating the bending moment of the oil and gas pipeline, the suspension of the pipeline can be effectively identified. The system assesses the impact on suspended oil and gas pipelines, thereby accurately identifying their safety. Based on the pipeline parameters and the maximum combined bending moment, it determines the risk warning information for the target oil and gas pipeline and provides risk alerts. By analyzing the stress state of suspended oil and gas pipelines in real time, it can promptly identify existing risks. Through timely risk warnings and continuous risk monitoring, it can quickly address risks associated with suspended oil and gas pipelines, solving the technical problem of the inability to provide real-time risk warnings for suspended oil and gas pipelines in existing technologies. This effectively ensures the transportation safety and equipment safety of suspended oil and gas pipelines.

Detailed Implementation

[0012] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0013] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0014] Figure 1 This invention provides a flowchart of a risk warning method for suspended oil and gas pipelines. This embodiment is applicable to real-time risk monitoring of oil and gas pipelines suspended due to river erosion. The method can be executed by a risk warning device for suspended oil and gas pipelines, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes: S110. If a suspended target oil and gas pipeline is detected, collect the suspension parameters and pipeline parameters of the target oil and gas pipeline.

[0015] Optionally, the target oil and gas pipeline can be understood as an oil and gas pipeline under real-time monitoring. It should be noted that oil and gas pipelines are usually buried underground or have supporting structures, and in rare cases, they may become suspended in mid-air during normal operation. Typically, natural disasters occur in the area where the pipeline is located, causing underground or supported pipelines to become suspended. For example, the target oil and gas pipeline could be buried at a certain depth at the bottom of a riverbed. Due to the scouring effect of regional floods, the soil above and around the pipeline is washed away and carried away by the water flow, causing the riverbed elevation to drop, resulting in the target oil and gas pipeline being exposed and detached from the soil support, forming a suspended pipeline section in the river flood.

[0016] Optionally, by conducting real-time environmental monitoring of the geographical areas along the oil and gas pipeline, when it is identified that some areas along the pipeline are affected by natural disasters, the corresponding oil and gas pipelines in those areas are designated as target oil and gas pipelines.

[0017] Optionally, after identifying the target oil and gas pipelines, real-time inspection equipment can be connected and deployed to inspect each pipeline to identify and analyze the real-time site environment and determine whether the pipeline is suspended. If the inspection equipment detects that the pipeline is suspended, a risk analysis is required. This inspection equipment could include visual sensors deployed along the pipeline route, drone inspection equipment, etc. For example, a target oil and gas pipeline located at a certain depth at the bottom of a riverbed might be exposed to floodwaters, or the soil settlement on both banks of the river might exceed the pipeline's burial depth, leading to the assessment that the pipeline has lost its soil support and is suspended.

[0018] Optionally, the suspension parameters can be the force characteristics of the target oil and gas pipeline when it is suspended, serving as key indicators to characterize the hydraulic effects and structural stresses on the pipeline. It should be noted that the suspension parameters include water flow density, water flow velocity, hydrodynamic coefficient, and water flow viscosity coefficient.

[0019] Optionally, pipeline parameters can be the pipeline structure and material information of the target oil and gas pipeline, including its structural and operational indicators. It should be noted that pipeline parameters include pipe material density, the density of the medium inside the pipeline, pipe wall thickness, pipe outer diameter, pipe bending section modulus, yield strength, and design safety factor.

[0020] Specifically, when the target oil and gas pipeline is identified as being suspended, data is collected from the target oil and gas pipeline to obtain its suspension parameters and pipeline parameters.

[0021] S120. Calculate the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters, respectively.

[0022] Optionally, the first direction and the second direction can be the direction of the force acting on the target oil and gas pipeline. Taking a target oil and gas pipeline suspended in a flood as an example, in the cross section of the suspended section of the pipeline under the action of flood, the first direction can be the direction of water flow, and the second direction can be perpendicular to the direction of water flow.

[0023] Optionally, the first directional load can be a uniformly distributed load acting on the suspended target oil and gas pipeline segment in the first direction; the second directional load can be a uniformly distributed load acting on the suspended target oil and gas pipeline segment in the second direction. For example, taking a suspended target oil and gas pipeline in a flood as an example, since both ends of the pipeline are buried in relatively hard soil layers on both sides of the river channel, and because the pipeline's stiffness is generally large, the deformation of the pipeline before failure is relatively small. The suspended pipeline is subjected to forces in both horizontal and vertical directions. Under the action of these two forces, the pipeline will undergo combined bending deformation in both horizontal and vertical directions. Assuming that the pipeline only undergoes linear elastic deformation under external forces, the principle of linear elastic superposition can be used to transform the stress situation of the target oil and gas pipeline in the flood into an elastic mechanical problem of a beam with fixed ends under the first and second directional loads.

[0024] Specifically, pipeline parameters are collected, and the suspension parameters of the target oil and gas pipeline are collected in real time. Then, based on the suspension parameters and pipeline parameters, the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline are calculated respectively.

[0025] Optionally, in another optional embodiment of the present invention, the step of calculating the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters includes: calculating the stable drag force and the pulsating drag force of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters; calculating the pipeline self-weight, pulsating lift force and buoyancy of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters; determining the first directional load based on the stable drag force and the pulsating drag force; and determining the second directional load based on the pipeline self-weight, the pulsating lift force and the buoyancy.

[0026] Optionally, the stable drag force and the pulsating drag force can be the forces exerted on the target oil and gas pipeline by the water flow in the first direction during the flood scouring process. The pipeline's self-weight, pulsating uplift force, and buoyancy can be the forces exerted on the target oil and gas pipeline in the second direction during the flood scouring process. Here, the pipeline's self-weight refers to the weight of the pipeline and the medium it transports. For example, the stable drag force is determined by F... D This is represented by the pulsating drag force via F. I The pipeline's self-weight is represented by G, and the pulsating upward force is represented by F. L The buoyancy of the water on the pipe is represented by F. f The stable drag force F is represented. D pulsating drag force F I The pipe's own weight G, and the pulsating upward force F. L The buoyancy F of the water on the pipe f The calculation method is as follows: Where, ρ w ρ is the density of the flood, kg / m³. w =ρ0(1-S v )+ρ s S v ,ρ0、ρ s These are the densities of water and sediment per unit volume of floodwater, respectively, in kg / m³. 3 S v The sand content per unit volume; ρ p ρ i These are the density of the pipe material and the density of the medium inside the pipe, respectively, in kg / m³. 3 δ is the pipe wall thickness, in meters; V is the water flow velocity perpendicular to the pipe axis, in meters per second; t is time, in seconds; C D C L C M The dynamic viscosity coefficient can be obtained from Table 1 based on the Reynolds number Re of the water flow, where Re = VD / η, D is the outer diameter of the pipe (m), and η is the kinematic viscosity coefficient of the water flow, which is taken as 1.0 × 10⁻⁶ at room temperature (0~20℃). -6 m 2 / s; g is the acceleration due to gravity, taken as 9.8 m / s². 2 f0 is the eddy emission frequency of the river, in Hz, and its calculation formula is: Among them, S r is the Strouhal number, which is related to the Reynolds number Re, and is generally taken as 0.2. When 250 ≤ Re ≤ 200000, its calculation formula is: Table 1 shows the relationship between the hydrodynamic coefficient and the Reynolds number Re, as follows: Specifically, the stable drag force and pulsating drag force of the target oil and gas pipeline are calculated based on the suspension parameters and pipeline parameters; the pipeline self-weight, pulsating lift force and buoyancy of the target oil and gas pipeline are calculated based on the suspension parameters and pipeline parameters; the first directional load is determined based on the stable drag force and pulsating drag force; and the second directional load is determined based on the pipeline self-weight, pulsating lift force and buoyancy.

[0027] S130. Identify the maximum combined bending moment based on the first directional load and the second directional load, and determine the maximum combined bending moment.

[0028] Optionally, the maximum combined bending moment can be the maximum combined bending moment generated in the target oil and gas pipeline under the combined action of the first directional load and the second directional load. It should be noted that the target oil and gas pipeline will experience combined bending under the combined action of the first directional load and the second directional load, and this bending determines whether the target oil and gas pipeline will be damaged under the action of flood scouring. This application selects the most dangerous point on the most dangerous section, that is, the maximum bending moment of the pipeline occurs at both ends, that is, the maximum combined bending moment at both ends of the target oil and gas pipeline.

[0029] Specifically, the maximum combined bending moment is identified based on the first directional load and the second directional load, and the maximum combined bending moment is determined.

[0030] S140. Determine the risk warning information of the target oil and gas pipeline based on the pipeline parameters and the maximum combined bending moment, and issue a risk warning based on the risk warning information.

[0031] Optionally, risk warning information can be a message alerting the target oil and gas pipeline to safety risks. It should be noted that risk warning information can be divided into multiple levels to provide multi-level early warning of safety risks to the target oil and gas pipeline. Specifically, it can be divided into mild, moderate, and severe warnings. Each risk warning message displays a title indicating whether it is a mild, moderate, or severe warning through text and / or color. Its content includes the estimated length of the suspended section, environmental risk information, real-time pipeline status, and warning recommendations. For example, a risk warning message could be as follows: Moderate warning, suspended length 25 meters, environmental risk information: continuous flooding, loose riverbed soil, potential for further development of the suspended section, real-time pipeline status: real-time safety factor 2.5, within the normal range, warning recommendation: temporary protective measures are needed, and emergency resources should be prepared.

[0032] Optionally, risk alerts can be used to notify relevant emergency personnel working on the target oil and gas pipeline. Risk alerts can be issued in various ways, such as via SMS warnings to relevant emergency personnel and push notifications through a work app.

[0033] Optionally, after obtaining the maximum combined bending moment, risk analysis can be performed using the maximum combined bending moment and pipeline parameters to obtain risk warning information for the target oil and gas pipeline.

[0034] Specifically, risk warning information for the target oil and gas pipeline is determined based on pipeline parameters and the maximum combined bending moment, and risk alerts are issued based on the risk warning information.

[0035] The technical solution of this invention, when a suspended target oil and gas pipeline is detected, collects the suspension parameters and pipeline parameters of the target oil and gas pipeline. Upon identification of a suspended oil and gas pipeline, relevant parameters of the current oil and gas pipeline are acquired in real time for real-time risk analysis. Based on the suspension parameters and pipeline parameters, a first-direction load in a first direction and a second-direction load in a second direction are calculated for the target oil and gas pipeline. The maximum combined bending moment is identified based on the first-direction load and the second-direction load. By calculating the bending moment of the oil and gas pipeline, the suspension of the pipeline can be effectively identified. The system assesses the impact on suspended oil and gas pipelines, thereby accurately identifying their safety. Based on the pipeline parameters and the maximum combined bending moment, it determines the risk warning information for the target oil and gas pipeline and provides risk alerts. By analyzing the stress state of suspended oil and gas pipelines in real time, it can promptly identify existing risks. Through timely risk warnings and continuous risk monitoring, it can quickly address risks associated with suspended oil and gas pipelines, solving the technical problem of the inability to provide real-time risk warnings for suspended oil and gas pipelines in existing technologies. This effectively ensures the transportation safety and equipment safety of suspended oil and gas pipelines.

[0036] Figure 2 This is a flowchart illustrating another risk warning method for suspended oil and gas pipelines provided by an embodiment of the present invention. The relationship between this embodiment and the above embodiments is that this specifically describes the process of identifying the maximum combined bending moment. For example... Figure 2 As shown, the method includes: S210. If a suspended target oil and gas pipeline is detected, collect the suspension parameters and pipeline parameters of the target oil and gas pipeline.

[0037] S220. Calculate the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters, respectively.

[0038] S230. Determine the first bending moment equation acting alone in the first direction based on the first directional load; determine the second bending moment equation acting alone in the second direction based on the second directional load; identify the maximum combined bending moment based on the first bending moment equation and the second bending moment equation, and determine the maximum combined bending moment.

[0039] Optionally, the bending moment equation can be a mathematical equation describing the distribution of bending moment along the length of the suspended target oil and gas pipeline; the first bending moment equation can be understood as describing the distribution of bending moment when a first directional load acts alone in the first direction; the second bending moment equation can be understood as describing the distribution of bending moment when a second directional load acts alone in the second direction. It should be noted that in this invention, under the sole action of the first directional load, the pipeline will bend in the xoy plane. By considering the suspended target oil and gas pipeline as a beam constrained at both ends, with the fixed-end constraints removed, each end is subjected to two forces and one bending moment, which can be considered a third-order statically indeterminate problem. Under the sole action of the second directional load, the pipeline will also bend in the xoz plane, which can also be considered a third-order statically indeterminate problem.

[0040] Specifically, the first bending moment equation acting alone in the first direction is determined based on the first directional load; the second bending moment equation acting alone in the second direction is determined based on the second directional load; and the maximum combined bending moment is identified based on the first and second bending moment equations to determine the maximum combined bending moment.

[0041] Optionally, in another optional embodiment of the present invention, determining the first bending moment equation acting alone in the first direction based on the first directional load includes: The first and second vertical reactions are determined based on the load in the first direction using equilibrium equations and the principle of symmetry. An equivalent model of the pipe bending moment of the target oil and gas pipeline in the first direction is constructed. The deformation compatibility equation is established and solved based on the load in the first direction and the equivalent model of the pipe bending moment using the superposition principle. The bending moment at the first and second ends of the target oil and gas pipeline is determined. The first bending moment equation is constructed based on the first vertical reaction, the second vertical reaction, the bending moment at the first end, and the bending moment at the second end using the section method.

[0042] Optionally, the first vertical reaction force can be the vertical reaction force at the first end of the target oil and gas pipeline; the second vertical reaction force can be the vertical reaction force at the second end of the target oil and gas pipeline. It should be noted that under the sole action of the first directional load, the pipeline will undergo bending in the xoy plane, which can be considered a third-order statically indeterminate problem. Since the horizontal constraint forces at both ends of the target oil and gas pipeline are extremely small under small deformation conditions, they can generally be ignored. Based on the equilibrium equations and the principle of symmetry, the first and second vertical reaction forces are calculated. For example, the first vertical reaction force is obtained through F... Ay The second vertical reaction force is represented by F. By To represent, and F Ay =F By =q1l / 2, where q1 is the load in the first direction.

[0043] Optionally, the equivalent model for the pipeline bending moment can be an equivalent model of a statically indeterminate beam representing the target oil and gas pipeline suspended in a flood. It should be noted that after obtaining the first and second vertical reactions, since the horizontal constraint forces at both ends of the target oil and gas pipeline are negligible, if the constraints restricting the pipeline rotation at the fixed ends A and B of the target oil and gas pipeline are redundant constraints, and the bending moment M at the first end is used as the basis for calculation... A Second end moment M B Instead of its function, an equivalent model of pipe bending moment is established based on the statically indeterminate beam.

[0044] Optionally, the deformation compatibility condition based on the equivalent model of pipe bending moment is the rotation angle θ at cross sections A and B. A θ B All are 0. Based on the superposition principle, a deformation compatibility equation is established, and the deformation compatibility equation M is solved. A =M B =q1l 2 / 12, meaning that under this bending moment, the upper part of the pipe is under tension. For example, the deformation compatibility equation is: Where EI represents pipe stiffness. Optionally, with point A as the zero point of the x-axis, the bending moment equation at any cross-section of the target oil and gas pipeline, i.e., the first bending moment equation, can be obtained using the section method. For example, the expression for the first bending moment equation is: The first bending moment equation represents a parabolic distribution along the length of the pipe, opening upwards, meaning it reaches a positive maximum value q1l at both ends of the pipe. 2 / 12, under this bending moment, the upper part of the pipe is under tension. At the center of the pipe, the maximum negative value, -q1l, is achieved. 2 / 24, under this bending moment, the lower part of the pipe is under tension. Furthermore, the direction of the tensile stress is along the x-axis.

[0045] Optionally, based on the same calculation process, the pipe will bend in the xoz plane under the second directional load alone. Taking point A as the zero point of the x-axis, the expression for the second bending moment equation under the second directional load q2 alone can be obtained as follows: The second bending moment equation can also be obtained at x=0 and l The maximum positive value q2l is obtained at both ends of the pipe. 2 / 12, under this bending moment, the upper part of the pipe is under tension. At the center of the pipe, the maximum negative value, -q²l, is achieved. 2 / 24, under this bending moment, the lower part of the pipe is under tension. Furthermore, the direction of the tensile stress is along the z-axis.

[0046] Specifically, the first and second vertical reactions are determined based on the load in the first direction using equilibrium equations and the principle of symmetry; an equivalent model of the pipe bending moment of the target oil and gas pipeline in the first direction is constructed; the deformation compatibility equation is established and solved based on the load in the first direction and the equivalent model of the pipe bending moment using the superposition principle, and the bending moments at the first and second ends of the target oil and gas pipeline are determined; and the first bending moment equation is constructed based on the first vertical reaction, the second vertical reaction, the bending moments at the first and second ends using the section method.

[0047] Optionally, in another optional embodiment of the present invention, the step of identifying the maximum combined bending moment based on the first bending moment equation and the second bending moment equation, and determining the maximum combined bending moment, includes: The combined bending moment equation is determined by performing combined bending calculations on the first bending moment equation and the second bending moment equation; based on the combined bending moment equation, the maximum combined bending moment of the target oil and gas pipeline in the suspended state is identified.

[0048] Optionally, the combined bending moment equation can be a equation describing the combined bending moment of the target oil and gas pipeline under the combined action of a first directional load and a second directional load. It should be noted that under the individual action of the first directional load and the second directional load, the pipeline will experience bending in the xoy plane and xoz plane, respectively. According to the combined bending theory of beams, under the combined action of the first directional load and the second directional load, the pipeline will experience combined bending, and its combined bending moment equation is M. 合 The expression is: .

[0049] The most dangerous points on the most dangerous cross section are selected, i.e., the points where the maximum bending moment of the pipe occurs at both ends, namely: q1l 2 / 12 and q2l 2 / 12, which is the maximum combined bending moment (M) at both ends of the target oil and gas pipeline. 合 ) max The expression is: Specifically, the combined bending moment equation is determined by performing combined bending calculations on the first and second bending moment equations; based on the combined bending moment equation, the maximum combined bending moment of the target oil and gas pipeline in the suspended state is identified.

[0050] S240. Determine the risk warning information of the target oil and gas pipeline based on the pipeline parameters and the maximum combined bending moment, and issue a risk warning based on the risk warning information.

[0051] Optionally, in another optional embodiment of the present invention, determining the risk warning information of the target oil and gas pipeline based on the pipeline parameters and the maximum combined bending moment includes: The beam bending stress is solved based on the pipeline outer radius, pipeline wall thickness and the maximum combined bending moment in the pipeline parameters to determine the maximum tensile stress of the target oil and gas pipeline; risk identification is performed based on the yield strength and the maximum tensile stress in the pipeline parameters to determine the real-time safety factor; the risk warning information is determined based on the real-time safety factor and the design safety factor.

[0052] Optionally, the maximum tensile stress can be the maximum value of the tensile stress generated on the cross-section of the pipeline under bending. It should be noted that the maximum tensile stress of the target oil and gas pipeline can be obtained based on the beam bending stress solution method in mechanics of materials. For example, the maximum tensile stress of the target oil and gas pipeline is σ. max The expression is: Where W is the section modulus of the pipe, W=12πR 2 δ; R and δ represent the outer radius of the pipe and the wall thickness of the pipe, respectively.

[0053] Optionally, the real-time safety factor can be understood as an instantaneous, dynamic safety margin calculated based on the instantaneous maximum tensile stress of the current target oil and gas pipeline. It should be noted that the real-time safety factor = yield strength / maximum tensile stress, reflecting the safety margin of the current target oil and gas pipeline.

[0054] Optionally, pipeline safety can be verified based on the design safety factor, yield strength, and maximum tensile stress. Among them, [σ t ]、σ s and n are the allowable tensile stress, yield strength, and design safety factor of the pipeline, respectively.

[0055] Specifically, the beam bending stress is solved based on the pipeline outer radius, pipeline wall thickness and maximum combined bending moment in the pipeline parameters to determine the maximum tensile stress of the target oil and gas pipeline; risk identification is performed based on the yield strength and maximum tensile stress in the pipeline parameters to determine the real-time safety factor; and risk warning information is determined based on the real-time safety factor and the design safety factor.

[0056] The technical solution of this invention performs bending moment analysis on the target oil and gas pipeline to obtain the bending moment equation at any cross-section. Based on the combined bending moment analysis in two different directions, the combined bending moment is obtained. The maximum combined bending moment at the most dangerous point on the most dangerous cross-section is selected to analyze whether the target oil and gas pipeline can withstand flood erosion. Real-time safety analysis is performed and quickly synchronized to the staff, providing relevant risk handling suggestions to quickly handle the risky suspended oil and gas pipelines. This solves the technical problem in the prior art that it is impossible to provide real-time risk warning for suspended oil and gas pipelines, and achieves the beneficial effect of effectively ensuring the transportation safety and equipment safety of suspended oil and gas pipelines.

[0057] Figure 3 This is a schematic diagram of a risk warning device for a suspended oil and gas pipeline provided in an embodiment of the present invention. Figure 3 As shown, the device includes: a risk detection module 310, a pipeline load analysis module 320, a pipeline bending moment analysis module 330, and a risk early warning module 340; wherein, The risk detection module 310 is used to collect the suspension parameters and pipeline parameters of the target oil and gas pipeline when the existence of a suspended target oil and gas pipeline is detected. The pipeline load analysis module 320 is used to calculate the first directional load in the first direction and the second directional load in the second direction of the target oil and gas pipeline based on the suspension parameters and the pipeline parameters, respectively. The pipe bending moment analysis module 330 is used to identify the maximum combined bending moment based on the first directional load and the second directional load, and to determine the maximum combined bending moment. The risk warning module 340 is used to determine the risk warning information of the target oil and gas pipeline based on the pipeline parameters and the maximum combined bending moment, and to provide risk warnings based on the risk warning information.

[0058] The technical solution of this invention, when a suspended target oil and gas pipeline is detected, collects the suspension parameters and pipeline parameters of the target oil and gas pipeline. Upon identification of a suspended oil and gas pipeline, relevant parameters of the current oil and gas pipeline are acquired in real time for real-time risk analysis.
