Description

Technical Field

[0001] The present invention relates to the technical field of submarine oil transportation, and in particular to a pipeline leakage intelligent reorganization and recovery method and device based on a pipeline network topology structure. Background Art

[0002] In recent years, with the continuous development of my country's economy, the exploration task of oil and gas resources has become increasingly heavy. While major domestic oil fields are stepping up the deployment of manpower and material resources to carry out refined management of old oil fields, they are also constantly expanding oil and gas exploration areas. As my country's offshore oil and gas development efforts increase, the pace of submarine pipeline construction is also accelerating. Since the construction of the first submarine oil pipeline in Chengbei Oilfield in Bohai Sea in 1985, my country has laid more than 250 submarine pipelines with a total length of more than 5,000 kilometers. These submarine pipelines undertake the important task of transporting offshore oil and gas fields.

[0003] However, the harsh marine environment, aging pipelines, and third-party factors, such as ship anchoring operations, fishing boats trawling, and ship collisions, can easily cause damage to submarine pipelines or even leaks. At present, most submarine pipelines in my country need to stop the transportation of oil and gas during maintenance. Although the technology for non-stop maintenance is constantly developing, there are many limitations and the process is complicated. In addition, due to the harsh submarine maintenance environment, it takes a long time from the occurrence of pipeline leakage to the completion of maintenance. During this period, the crude oil leaked from the pipeline will seriously pollute the marine environment, and the suspension of oil field production will also cause huge economic losses.

[0004] Therefore, how to reduce the harm of oil pipeline leakage without affecting the normal production of oil fields is an urgent problem to be solved. Summary of the invention

[0005] In view of this, it is necessary to provide a pipeline leakage intelligent reorganization and recovery method and device based on the pipeline network topology structure to solve the technical problem that the existing technology cannot take into account both the normal production of the oil field and the reduction of the hazards of oil pipeline leakage.

[0019] If neither the single-pipeline candidate recovery solution nor the multi-pipeline candidate recovery solution is generated, a redundant pipeline is added to generate a no-pipeline candidate recovery solution.

[0022] In some possible implementations, the adding of redundant pipelines includes:

[0023] At least one redundant pipeline is added which can carry a flow rate greater than the flow rate of the leaking pipeline during normal operation and pass the flow pressure test.

[0048] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0049] It should be understood that the schematic drawings are not drawn to scale. The flow chart used in the present invention shows the operations implemented according to some embodiments of the present invention. It should be understood that the operations of the flow chart can be implemented out of order, and the steps without logical context can be reversed or implemented simultaneously. In addition, those skilled in the art can add one or more other operations to the flow chart under the guidance of the content of the present invention, and can also remove one or more operations from the flow chart.

[0050] Some of the block diagrams shown in the accompanying drawings are functional entities that do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor systems and / or microcontroller systems.

[0051] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] Before describing the embodiments, the following definitions are given for the relevant terms:

[0053] Negative pressure wave: When a leak is found in a pipeline, the local liquid reduction caused by the loss of fluid material at the leak site causes an instantaneous pressure drop and velocity difference. This instantaneous pressure drop acts on the fluid medium and acts as a decompression wave source, propagating to the upstream and downstream of the leak point through the pipeline and the fluid medium. When the pressure before the leak is used as the reference standard, the decompression wave generated during the leak is called a negative pressure wave, and this method is called the negative pressure wave detection method.

[0054] Flow balance: The flow balance principle means that according to the oil and gas storage and transportation theory, the sum of the input volume of the closed pipeline is equal to the sum of the output volume of the pipeline. In fact, the instantaneous flow of imports and exports is generally unbalanced. Under normal circumstances, the amplitude of the output difference is relatively stable. By using the method of real-time monitoring of the output difference, if the stable state of the output difference is destroyed, such as the amplitude of the output difference increases significantly, it can be determined that there is an abnormality in the pipeline; the output difference curve during the period of leakage can also be integrated by computer to accurately calculate the leakage amount.

[0055] Based on the description of the above technical terms, in the prior art, the location of the leaking pipeline is determined by combining the monitoring methods of negative pressure waves and flow balance. In the process of repairing the leaking pipeline, it is often necessary to stop the transportation of oil and gas, and because of the harsh seabed maintenance environment, the existing non-stop transportation maintenance technology takes a long time from the occurrence of pipeline leakage to the completion of maintenance, and the process is complicated. During this period, the crude oil leaked from the pipeline will seriously pollute the marine environment, and the suspension of oil field production will also cause huge economic losses. Therefore, the present invention aims to propose a pipeline leakage intelligent reorganization and recovery method based on the pipeline network topology structure, and according to the actual situation of the leaking pipeline, a reasonable recovery plan is given quickly and efficiently without affecting the normal production of the oil field.

[0056] The specific embodiments are described in detail below:

[0057] The embodiments of the present invention provide a pipeline leakage intelligent reorganization and recovery method, device and electronic equipment based on the pipeline network topology structure, which are described below respectively.

[0058] Figure 1 A schematic flow chart of an embodiment of a pipeline leakage intelligent reorganization and recovery method based on a pipeline network topology structure provided by the present invention is shown in FIG. Figure 1 As shown, the pipeline leakage intelligent reorganization and recovery method based on the pipeline network topology structure includes:

[0059] S101, constructing a pipe network topology structure, obtaining location information and flow information of all pipes in the pipe network topology structure, connection information between pipes, and valve information of pipe layout;

[0060] S102, obtaining leaking pipeline information;

[0061] S103, generating a preliminary recovery plan based on the leaking pipeline information, the location information and flow information of all pipelines, the connection information between pipelines, and the valve information arranged in the pipelines;

[0062] S104: Determine a final recovery plan according to the recovery cost and recovery efficiency of the preliminary recovery plan.

[0063] Compared with the prior art, the pipeline leakage intelligent reconstruction and recovery method based on the pipeline network topology structure provided by the embodiment of the present invention abstracts the pipeline network into a topology structure, determines a recovery plan based on the pipeline network topology structure according to the leaking pipeline information and the surrounding pipeline information, and selects a suitable recovery plan according to the actual situation, so as to achieve the purpose of taking into account the normal production of the oil field and reducing the harm of oil pipeline leakage.

[0064] In some embodiments of the present invention, the pipe network topology generally includes the name or number of each pipe in the pipe network, the relative position of each pipe, the connection method of each pipe, the flow direction of the fluid in each pipe, the maximum flow and current flow information of each pipe, the valve position information of each pipe, etc.

[0065] In some embodiments of the present invention, the obtaining of leaking pipeline information includes:

[0066] The position of the leaking pipeline, the position of the valve connected to the leaking pipeline, the connection relationship between the leaking pipeline and surrounding pipelines, and the flow rate of the leaking pipeline when it is working normally are obtained.

[0067] According to the position of the leakage pipeline, the position of the valve connected to the leakage pipeline, and the connection relationship between the leakage pipeline and the surrounding pipelines, a target surrounding pipeline having a transfer path with the leakage pipeline is determined in the surrounding pipelines.

[0068] In a specific embodiment of the present invention, the Nanbao 35-2 oil field pipeline is used as a model to generate a simplified pipeline diagram, such as Figure 2 As shown, Figure 2 The simplified pipeline diagram of the Nanbao 35-2 oilfield pipeline embodiment provided by the present invention can realize real-time detection of the transmission pipeline through the set flow meter and pressure transmitter. When a leak occurs, the location and information of the leaking pipeline can be quickly determined through the CEP and WHPB operating platforms, and corresponding measures can be taken.

[0069] In some embodiments of the present invention, Figure 3 As shown, Figure 3 For the present invention Figure 1 The flowchart of step S103 of an embodiment includes:

[0070] S301, obtaining the flow rate of the leaking pipeline when it is working normally and the target surrounding pipeline information that has a transfer path with the leaking pipeline;

[0071] S302, selecting one by one the surrounding pipelines that have a transfer path with the leaking pipeline and satisfy the requirement that the remaining carrying flow is greater than the flow of the leaking pipeline when it is working normally, and performing flow pressure verification on each of them. If the verification passes, generating a single pipeline candidate recovery plan;

[0072] S303, combining any two or more pipelines from the surrounding pipelines that have a transfer path with the leaking pipeline, selecting pipeline combinations that satisfy the requirement that the sum of the remaining carrying flow is greater than the flow of the leaking pipeline when it is working normally, and performing flow pressure verification respectively. If the verification passes, generating a multi-pipeline candidate recovery plan;

[0073] S304: If neither the single-pipeline candidate recovery solution nor the multi-pipeline candidate recovery solution is generated, a redundant pipeline is added to generate a no-pipeline candidate recovery solution.

[0074] In some embodiments of the present invention, based on the leaking pipeline information, the location information and flow information of all pipelines, the connection information between pipelines and the valve information of pipeline layout, the pipeline reorganization after leakage is achieved by adjusting the valve to close or open the leaking pipeline and / or the pipelines around the leaking pipeline.

[0075] In some embodiments of the present invention, the adding of redundant pipelines includes:

[0076] At least one redundant pipeline is added which can carry a flow rate greater than the flow rate of the leaking pipeline during normal operation and pass the flow pressure test.

[0077] It should be noted that: in case of leakage in long-distance submarine transmission pipelines, a smaller diameter pipeline is installed along the submarine pipeline, and connected to the transmission pipeline through a valve every kilometer. When a leak occurs at a certain point, the leak point is bypassed through the auxiliary pipe. At the same time, the upper station changes the transmission medium to water, and the submarine pipeline leak point is quickly repaired through underwater robots and other repair methods.

[0078] In order to more intuitively demonstrate the pipeline leakage intelligent reorganization and recovery method based on the pipeline network topology structure provided by the present invention, the method provided by the present invention is described below in conjunction with specific embodiments. Figure 4 , Figure 4 The topological structure diagram of the embodiment of the Nanbao 35-2 oil field pipeline provided by the present invention, according to the topological model of the pipeline, it is concluded that when a leak occurs in the pipeline at ① to ⑧, the recovery scheme is as follows:

[0079] When a leak occurs in the pipeline at ①, there is no recovery plan;

[0080] When a leak occurs in the pipeline at ②, there is no recovery plan;

[0081] When a leak occurs in the pipeline at ③, close valve No. 3 first, then open valve No. 4;

[0082] When a leak occurs in the pipeline at ④, close valve No. 9 first, then open valve No. 19;

[0083] When a leak occurs in the pipeline at ⑤, there is no recovery plan;

[0084] When leakage occurs in the pipeline at ⑥, close valves 16 and 18;

[0085] When leakage occurs in the pipeline at ⑦, close valves 7 and 18;

[0086] When a leak occurs in the pipeline at ⑧, there is no recovery plan.

[0087] When there are few candidate solutions available, some pipelines leak and there are no candidate solutions to choose from, so the impact of pipeline leakage cannot be eliminated in time. Therefore, it is necessary to add redundant pipelines to some pipelines in the oil field, and then regenerate the recovery plan according to the above strategy. It is found that when ①, ②, ⑤, and ⑧ leak, there is no recovery plan to choose from. At this time, it is necessary to add redundant pipelines. Please refer to Figure 5 , Figure 5 This is a topological structure diagram of an embodiment of the Nanbao 35-2 oil field pipeline provided by the present invention after adding redundant pipelines. According to the topological model of the pipeline after adding redundant pipelines, it is concluded that after leakage occurs at points ① to ⑧, the recovery plan is as follows:

[0088] When leakage occurs in the pipeline at ①, open valves 21 and 22;

[0089] When leakage occurs in the pipeline at ②, open valve No. 23 and close valve No. 1;

[0090] When a leak occurs in the pipeline at ③, first close valve No. 3, open valve No. 4, then open valve No. 23, and adjust valves No. 1 and No. 5;

[0091] When leakage occurs in the pipeline at ④, first close valves 9 and 18, then close valves 9 and 26, and adjust valve 25;

[0092] When leakage occurs in the pipeline at ⑤, first close valve No. 14, open valve No. 26, then close valve No. 14, and adjust valves No. 25, No. 9, and No. 11;

[0093] When leakage occurs in the pipeline at ⑥, close valves 16 and 18;

[0094] When leakage occurs in the pipeline at ⑦, close valves 7 and 18;

[0095] When leakage occurs in pipeline ⑧, open valves 28 and 29.

[0096] The embodiment of the present invention determines a recovery plan based on the leaking pipeline information and the surrounding pipeline information, realizes pipeline reorganization by adjusting valves, and selects and generates multiple recovery plans according to actual conditions. When the staff or the monitoring system observes a pipeline leak, a suitable recovery plan can be selected from the generated recovery plans.

[0097] In some embodiments of the present invention, determining the final recovery plan according to the recovery cost and recovery efficiency of the recovery plan includes:

[0098] The restoration costs include: the cost of repairing leaking pipelines and / or the cost of adding redundant pipelines;

[0099] The recovery efficiency includes: the time to repair the leaking pipeline and / or the time to add a redundant pipeline;

[0100] The final recovery plan is determined according to the recovery effect index P, and the calculation formula of the recovery effect index P is as follows:

[0101]

[0102] Among them, β and γ represent weight coefficients, M1 and M2 represent the cost level of repairing leaking pipelines and the cost level of adding redundant pipelines, respectively, T1 and T2 represent the time of repairing leaking pipelines and the time of adding redundant pipelines, respectively, and the larger the value of the restoration effect index P, the better the restoration effect;

[0103] By comparing the recovery effect indicators of different recovery plans, the final recovery plan is determined to achieve the recovery of the leaking pipeline.

[0104] In a specific implementation of the present invention, the sum of the weight coefficients β and γ is 1, and the values ​​thereof can be adjusted according to the actual situation, M1 and M2 respectively represent the cost level of repairing the leaking pipeline and the cost level of adding redundant pipelines, and the value range of M1 and M2 is 1 to 10, representing 10 levels of repair costs from low to high, respectively, T1 and T2 respectively represent the time to repair the leaking pipeline and the time to add redundant pipelines, and the value range of T1 and T2 is 1 to 10, representing 10 levels of repair time from short to long. And the repairing of the leaking pipeline and the adding of redundant pipelines can be carried out simultaneously or successively.

[0105] The embodiment of the present invention assigns corresponding weights to the restoration cost and the restoration efficiency, so that in the actual process of repairing a leaking pipeline, the weight coefficient can be adjusted according to the actual situation (such as the degree of pipeline damage, the urgency of the repair time, and the impact of pipeline adjustment, etc.), and the restoration plan that best suits the current situation is selected to reduce the economic losses and environmental pollution caused by pipeline leakage.
