[0002] In recent years, my country's oil pipeline construction has developed by leaps and bounds and has become an important strategic energy infrastructure, making great contributions to the national economy and social development. However, since oil pipelines are often deployed in various complex environments and are affected by various adverse factors, the risk of pipeline leakage is also increased. Once an oil leakage pollution accident occurs, the impact is huge.

[0003] Pipelines crossing rivers are more prone to oil leakage accidents due to natural disasters (earthquakes, landslides, mudslides, etc.), pipeline corrosion, pipeline welding defects, pipe quality defects, third-party damage, etc. If a leak occurs, it will cause the following impacts:

[0004] (1) Pipeline shutdown affects downstream users, causing economic losses to enterprises and adverse social impacts;

[0005] (2) Affecting the production and life of villagers in nearby villages and towns;

[0006] (3) Oil products flowing into the river will cause serious pollution to the vegetation and soil in the riverside area;

[0007] (4) If effective oil spill interception is not carried out in a timely manner after oil flows out of international rivers, the oil spill will flow into neighboring countries with the water, causing not only huge environmental pollution but also adverse international impacts.

[0037] 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 only 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.

[0038] In order to solve the deficiencies of the prior art, the present invention discloses a pipeline leakage optimization processing method based on risk constraints. Figure 1 FIG. 1 is a flow chart of a pipeline leakage optimization processing method based on risk constraints of the present invention, such as Figure 1 As shown, the method comprises the following steps:

[0039] Step S101, determining a pipeline leakage point; the pipeline crosses a river and the leakage point is located at the crossing point;

[0040] Step S102, determining the location for processing the leakage point;

[0041] Step S103: Emergency response personnel deploy oil interception facilities at the location.

[0042] In step S101 of the present invention, the pipeline is also called an oil pipeline, and the oil products it transports include but are not limited to: crude oil and refined oil. The leakage of the pipeline may be caused by one or more factors such as natural disasters (earthquakes, landslides, mudslides, etc.), pipeline corrosion, pipeline welding defects, pipe quality defects and third-party damage. The types of leakage are not limited to: sand holes, small holes, ruptures and fractures.

[0043] Furthermore, the specific location where the leakage occurs in the oil pipeline can be determined by using pipeline leakage detection and positioning technology. For example, available pipeline leakage detection and positioning technologies include but are not limited to one or more of the following technologies: distributed optical fiber detection, magnetic flux leakage detection, model detection, negative pressure wave detection, sound wave detection, correlation analysis detection, empirical mode decomposition detection, neural network detection and support vector machine detection.

[0044] In step S102 of the present invention, the leakage occurs at the crossing of the river in the oil pipeline, and the leaked oil moves downstream along with the water in the river. The treatment of the leakage point refers to recovering and / or removing the oil leaked into the river. Therefore, in this article, the location for treating the leakage point is located downstream of the oil leakage point.

[0045] Furthermore, for risk constraints, it is necessary to select an appropriate location to treat the leak. On the one hand, the treatment location should be as close as possible to the oil leak point to minimize the pollution and damage of the oil to the environment through which it flows. On the other hand, the selection of the treatment location needs to be able to achieve effective recovery and / or removal of the oil.

[0046] Preferably, the time it takes for the oil leak point to reach the treatment location is equal to or greater than the time it takes for emergency personnel to deploy oil interception facilities at the treatment location, so that the deployment of oil interception facilities is completed at the same time or before the oil reaches the treatment location to effectively intercept the leaked oil.

[0047] Furthermore, the time it takes for the oil leakage point to reach the treatment location usually depends on the river conditions, including river water flow, flow velocity, water level during flood and dry seasons, river width, slope ratio, terrain conditions, etc., as well as the properties of the transported oil, including density, delivery pressure, actual delivery volume, etc.

[0048] In step S103 of the present invention, the time when the emergency treatment personnel place the oil interception facility at the processing location may specifically include the time when the emergency treatment personnel arrive at the processing location, the transportation time of the oil interception facility and / or the time when the oil interception facility is placed at the processing location. In some embodiments, the oil interception facility may be stored at the processing location. In this case, the time when the emergency treatment personnel place the oil interception facility at the processing location may be the sum of the time when the emergency treatment personnel arrive at the processing location and the time when the oil interception facility is placed at the processing location.

[0049] In the optimization method of the present invention, the selection of the treatment location plays an important role. The selection of the treatment location needs to meet the deployment conditions of the oil interception facilities. The oil interception facilities may include oil booms, oil skimmers, oil absorption felts, oil absorption cotton, oil gelling agents, and oil dispersants.

[0050] Furthermore, the deployment of oil containment facilities including oil booms needs to consider the influence of water flow velocity. When the flow velocity in the direction perpendicular to the oil boom exceeds a certain value, the spilled oil will escape from the bottom of the boom, rendering the boom ineffective. Therefore, when deploying oil booms in rivers or coastal waters, the booms need to be deployed at a certain angle to the water flow to ensure that the speed does not exceed the critical speed. At the same time, the angle of the booms needs to be adjusted in time according to the flow direction to reduce the relative speed between the booms and the spilled oil. The spilled oil can also be directed to waters with lower flow velocities for recovery. The vector relationship between the angle between the oil boom and the water flow can determine the angle between the oil boom and the water flow, and the calculation formula is as follows:

[0051] sinα=V lim / V 水 ; (1)

[0052] In formula (1), α is the angle between the oil boom and the water flow; V lim V is the limiting flow velocity perpendicular to the oil boom; 水 is the actual water flow velocity.

[0053] According to the above formula, the minimum angle between the oil boom and the water flow is 15°, so the formula can be used to derive the limiting flow velocity V at which the oil boom can function. lim is 1.2m / s, that is, only at the highest flow velocity V 水 Oil spill containment operations can only be carried out in river sections where the speed does not exceed 1.2m / s.

[0054] Furthermore, the deployment of oil containment facilities including oil booms also needs to take into account the river's geographical conditions. Specifically, the deployment site of the oil booms is required to be close to the shore and easy to reach, and the upstream area adjacent to the oil booms is undisturbed calm waters to ensure that the oil spill has a chance to be separated and float to the surface. In other words, the water flow in the area upstream of the treatment location is gentler than the water flow at the treatment location. For example, the flow rate of the water flow in the area upstream of the treatment location is less than the flow rate of the water flow at the treatment location. Usually, these calm waters are generally located on the inside of the river bend or in places with vegetation or protruding rocks. These places often have wider rivers and gentler water flows, and are the best places for oil spill diversion and recovery.

[0055] Furthermore, the deployment of oil containment facilities including oil booms also needs to consider the influence of water depth. In other words, the deployment of oil booms should consider whether the tidal range and water depth of the water area can meet the draft requirements of the oil booms. Suitably, the water depth of the area where the oil booms are deployed can be at least 3 times the draft of the oil booms. Otherwise, if the water depth is not enough, even if the oil booms are deployed, the containment function of the oil booms will be lost.

[0056] Preferably, the boom can be fixed by using fence posts and anchors to maintain the containment shape of the boom. For narrower rivers, the boom can be fixed on the shore with fence posts. Depending on the required fixing force, one fence post or multiple fence posts can be used. Alternatively, the boom can be fixed with anchors. When using anchors, the bottom structure (sand, stone or rock), flow direction, flow velocity and water depth should be mastered to ensure the size, effectiveness and safety of the anchor. For example, the anchoring site of the boom should be selected in a river section with relatively gentle water flow, where the water flow velocity cannot exceed the limit flow velocity, and it is necessary to consider setting the anchor in a place with gentle water flow. If the flow direction of the water area where the boom is deployed is unidirectional, the anchor must be placed on the side of the boom facing the flow direction. If the flow direction changes, such as in the intertidal zone, anchors must be set on both sides of the boom. Most booms have anchor seats or boom connectors for connecting anchors.

[0057] Furthermore, the number and size of anchors used depends on factors such as the force acting on the boom, water flow, waves, flow direction, boom length, ship size, etc. The formula for the water flow force on a floating boom in the water is as follows:

[0058] F=C d ρAV 2 / 2g; (2)

[0059] In formula (2): F is the force of water flow; C d is the boom control shape coefficient (value is 2); ρ is the density of water (value is 1000kg / m 3 ); A is the projection area of ​​the total area under the water surface of the oil boom in the direction perpendicular to the flow velocity; V is the average flow velocity on the river surface, m / s; g is the acceleration of gravity (the value is 9.8m / s 2 ).

[0060] Furthermore, when selecting an anchor, the load on the boom should be calculated according to formula (2), and then an anchor that can provide sufficient mooring force should be selected. In order to avoid excessive mooring force requirements for the anchor when using a single anchor, multiple anchors are generally used. Under normal circumstances, one or two anchors are dropped for every 40 to 80 m of a floating boom (height of about 1.2 m). For an inflatable boom (height of 2 m), 2 to 4 anchors can be dropped for every 100 m. According to the requirements of the JT / T "Oil Boom" standard for anchors for oil booms, when using manual placement and recovery anchors, the weight of a single anchor should not exceed 150 kg. The types of anchors can be high-grip anchors, fishing gear anchors or dovetail anchors, naval anchors, Danforth anchors, four-claw anchors, and single-arm anchors. Anchors with lifting devices weighing 20 to 100 kg are usually used.

[0061] Furthermore, the calculation formula of the anchor's mooring force is as follows:

[0062] P=Waλa; (3)

[0063] In formula (3), P is the mooring force of the anchor, N; Wa is the weight of the anchor in water, kg, which is 0.867 times the weight of the anchor in the air; λa is the holding coefficient of the anchor, and its value is selected as shown in Table 1 below:

[0064] Table 1

[0065] Bottom Slime Hard mud Sand and mud sand Gravel Small stones λa 10 9 8 7 6 5

[0066] The grip of the anchor is affected by the current and its own weight, as well as other factors, mainly the angle between the anchor rod and the seabed. The most suitable angle is 0°. If the anchor rod is lifted by more than 10%, the grip of the anchor is significantly reduced. Connecting the anchor rod with the anchor chain can reduce the movement of the anchor rod. Similarly, using the anchor ball can prevent the anchor rod from being lifted. The anchor ball can form a certain angle between the oil boom and the anchor rope, which can reduce the impact of the movement of the oil boom system on the anchor system.

[0067] To prevent the anchor from being lifted by waves, the length of the rope connecting the anchor and the mooring ball should be at least 3 times the water depth. The length of the anchor rope under different sea conditions. In normal sea conditions, the length of the anchor rope is 5 times the water depth: in calm waters, the length of the anchor rope is 3 times the water depth; in severe sea conditions, the length of the anchor rope is 7 times the water depth.

[0068] The size of the anchor ball is determined by the weight of the anchor, and the volume of the anchor ball is usually 60 to 250L. From a safety perspective, in order to prevent the long time of anchor recovery from affecting the rapid movement of the oil boom, a quick release device such as a shackle is usually used between the anchor ball and the oil boom. In addition, the selection of the processing location also needs to consider factors such as whether the access road is unobstructed and whether there are external resources around that can be relied on.

[0069] In addition, for the sake of risk constraints, it is always hoped that the time for emergency response personnel to deploy oil containment facilities can be reduced as much as possible. To this end, the oil containment facilities can be properly stored. For example, the oil boom can be placed in a zigzag order. Suitably, the oil boom tow head and towing rope can be connected to one end of the oil boom for direct deployment. According to different water flow speeds and navigation requirements, there are other placement shapes, such as "V" shape, "eight" shape, ladder shape, etc., among which the "Z" shape is suitable for calm water surface and no navigation.

[0070] The following specific examples are provided to further illustrate the present invention, but they should not be construed as limiting the present invention to the details described in the examples.

[0071] Embodiment 1:

[0072] In Example 1 of the present invention, an optimization treatment analysis of oil leakage is performed on an oil pipeline in a river crossing area in my country. The river crossing area belongs to the river alluvial plain landform, with small terrain undulations, flat terrain, and the surface vegetation is mainly crops. The crossing section adopts a large excavation crossing method, with a horizontal length of 687m and a general horizontal length of 183m, a total of 879m. The regional level is level two, the design pressure of the natural gas pipeline at the crossing is 10MPa, and D1016×18.4, X80 straight seam submerged arc welded steel pipe is used. The design pressure of the crude oil pipeline is 10MPa, and the crossing section adopts D813×14.7, X70 straight seam submerged arc welded steel pipe. There is a monitoring valve chamber upstream of the pipeline at the crossing, and another one-way valve chamber downstream. The pipeline between the two valve chambers is 2650m long.

[0073] Specifically, embodiment 1 of the present invention provides an optimization processing method for pipeline leakage based on risk constraints, wherein the pipeline crosses a river and the leakage is located at the crossing point, including: determining a location for processing the leakage, and deploying oil containment facilities including oil booms at the location.

[0074] The leakage point was detected by negative pressure wave detection technology; and based on comprehensive consideration of factors such as water flow rate, river geographical conditions, and water depth, two suitable treatment locations located 2.6km and 42km downstream of the crossing were selected.

[0075] (1) The effectiveness judgment of the processing position of 2.6 km is shown in Table 2:

[0076] Table 2

[0077]

[0078] It can be seen from Table 2 that for the treatment location of 2.6 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is less than the time it takes for the emergency treatment personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material transportation time + material deployment time), so the leaked oil cannot be effectively intercepted.

[0079] (2) The validity judgment of the processing position of 42 km is shown in Table 3:

[0080] Table 3

[0081]

[0082] It can be seen from Table 3 that for the treatment location of 42 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is greater than the time it takes for the emergency treatment personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material transportation time + material deployment time), so the leaked oil can be effectively intercepted.

[0083] Example 2

[0084] In Example 2 of the present invention, an optimization treatment analysis of oil leakage is conducted for an oil pipeline in a river crossing area in my country. According to the topography and engineering geological conditions of the cross-section of the river, a cable suspension crossing scheme is adopted, the main span of the cable suspension is 320m, the design pressure of the natural gas pipeline at the crossing is 10MPa, and D1016×22.9, X80 straight seam submerged arc welded steel pipe is adopted; the design pressure of the oil pipeline is 15MPa, and the crossing section adopts D813×28.6, X70 straight seam submerged arc welded steel pipe. There is a monitoring valve chamber and another one-way valve chamber across the two banks, and the two valve chambers are 2.663km apart.

[0085] Specifically, embodiment 2 of the present invention provides an optimization processing method for pipeline leakage based on risk constraints, wherein the pipeline crosses a river and the leakage is located at the crossing point, comprising: determining a location for processing the leakage, and deploying oil containment facilities including oil booms at the location.

[0086] The leakage point was detected by negative pressure wave detection technology; and based on comprehensive consideration of factors such as water flow rate, river geographical conditions, and water depth, four suitable treatment locations were selected at 56km, 68km, 90km, and 149km downstream of the crossing.

[0087] (1) The validity judgment of the processing position of 56 km is shown in Table 4:

[0088] Table 4

[0089]

[0090] It can be seen from Table 4 that for the treatment location of 56 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is greater than the time it takes for the emergency personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material deployment time), so the leaked oil can be effectively intercepted.

[0091] (2) The validity judgment of the processing position of 68 km is shown in Table 5:

[0092] Table 5

[0093]

[0094] It can be seen from Table 5 that for the treatment location of 68 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is greater than the time it takes for the emergency treatment personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material deployment time), so the leaked oil can be effectively intercepted.

[0095] (3) The validity judgment of the processing position of 90 km is shown in Table 6:

[0096] Table 6

[0097]

[0098] It can be seen from Table 6 that for the treatment location of 90 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is greater than the time it takes for the emergency treatment personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material transportation time + material deployment time), so the leaked oil can be effectively intercepted.

[0099] (4) The validity judgment of the processing position of 149 km is shown in Table 7:

[0100] Table 7

[0101]

[0102] It can be seen from Table 7 that for the treatment location of 149 km, whether in the non-flood season or the flood season, the time it takes for the leaked oil to reach the treatment location is greater than the time it takes for the emergency treatment personnel to deploy the oil interception facilities at the treatment location (emergency personnel arrival time + material transportation time + material deployment time), so the leaked oil can be effectively intercepted.
