Description

Technical Field

[0001] The present application relates to the technical field of gas transmission pipelines, and in particular to a distributed pipeline design method, equipment, storage medium and program product. Background Art

[0002] In the existing pipeline design technology, the designed transmission capacity of the pipeline is mainly based on the "Gas Transmission Pipeline Design Specification" which stipulates that "the designed transmission capacity of the gas transmission pipeline shall be determined according to the annual or daily maximum gas transmission volume specified in the letter of entrustment or contract." With the gradual formation of the "one network across the country" of natural gas, a distribution pipeline has emerged. The distribution pipeline can receive upstream resources and transfer (in or out) resources to other pipelines connected to the distribution pipeline.

[0003] Since the distribution pipeline is connected with multiple pipelines and intersects with each other to form a pipeline network, the existing technology cannot determine the design transmission capacity of the distribution pipeline when designing the distribution pipeline, which leads to the problem of pipeline scale being too large or too small when designing the distribution pipeline. However, the distribution pipeline that is too large has high construction cost, long cycle, and low pipeline efficiency; the distribution pipeline that is too small cannot guarantee the normal transfer of resources, affecting the safe transportation and flexible allocation of resources.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0043] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0044] In the existing pipeline design technology, the designed transmission capacity of the pipeline is mainly based on the "Gas Transmission Pipeline Design Specifications" which stipulates that "the designed transmission capacity of the gas transmission pipeline shall be determined according to the annual or daily maximum gas transmission volume specified in the letter of entrustment or contract." With the gradual formation of the "one network across the country" of natural gas, a distribution pipeline has emerged. The distribution pipeline can receive upstream resources and transfer resources to other pipelines connected to the distribution pipeline to transport resources to other regions.

[0045] Since the collecting and distributing pipeline is connected with multiple pipelines and intersects with each other to form a pipeline network, when designing the collecting and distributing pipeline, the existing technology cannot determine the designed transportation capacity of the collecting and distributing pipeline.

[0046] In response to the above problems, the present application provides a method for designing a distributed pipeline, including: segmenting the distributed pipeline to obtain all the pipeline sections of the distributed pipeline in the design area, and determining the output resource amount of each pipeline section node based on the external input resource amount, local uploaded resource amount, local consumed resource amount, and resource amount transferred to the interconnected pipeline of each pipeline section, thereby improving the accuracy of the overall design delivery amount. Based on the output resource amount of each pipeline section node, the overall design delivery amount of the distributed pipeline is determined, so that the distributed pipeline can be fully utilized, the utilization efficiency of the distributed pipeline is improved, and the pipeline design is performed based on the overall design delivery amount of the distributed pipeline, thereby improving the resource collection and evacuation capacity of the distributed pipeline, and improving the resource guarantee and allocation capacity of the area where the distributed pipeline is located.

[0047] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0048] The distributed pipeline design method provided in this application can be applied to electronic equipment.

[0049] Exemplarily, the electronic device may be a server, such as a server cluster consisting of multiple servers, or a single server, or a computer, or a processor or processing chip in a server or computer.

[0050] Exemplarily, the electronic device may be a terminal, such as a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop computer, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), etc.

[0051] See also Figure 1 , is a flow chart of a distributed pipeline design method provided in an embodiment of the present application, such as Figure 1 As shown, the distributed pipeline design method provided in the present application specifically includes the following steps S201 to S205:

[0052] S201, segment the distribution type pipeline to obtain all the pipeline sections of the distribution type pipeline in the design area.

[0053] In some embodiments, the centralized and distributed pipeline generally refers to a centralized pipeline network in a water supply, gas supply, or other fluid delivery system to achieve effective connection and resource transmission of multiple dispersed points. This system is generally composed of a trunk pipeline (manifold) and multiple interconnecting pipelines (distributed pipes), which can evenly transport resources in a certain area.

[0054] Exemplarily, the interconnecting pipelines are other pipelines having connection points with the collecting and distributing pipelines.

[0055] like Figure 2 As shown, pipelines A, B, C, D, E, F, G, and H are built pipelines, and pipelines a, b, and c are built pipelines (market-type pipelines, used to download resource volume). In order to better achieve resource balance, it is planned to build a new distribution pipeline to connect pipelines A, B, C, D, E, and H through connection points to gather and evacuate resources. Among them, the routes of pipelines C and D are the same; pipelines F and G are the same.

[0056] Exemplarily, the distribution-collection pipeline may be divided into at least one pipeline section based on key nodes such as the starting and ending points, resource uploading points, and resource transfer points.

[0057] Exemplarily, the pipe segment is a pipe connecting two adjacent key nodes after being divided based on the key nodes.

[0058] Exemplarily, the pipeline segment nodes are nodes such as resource upload points and resource transfer points that the pipeline segment passes through.

[0059] S202. For all pipe sections of the distribution type pipeline within the design area, determine the external input resource volume, local upload resource volume, local consumption resource volume and resource volume transferred to the interconnecting pipeline of each pipe section.

[0060] Exemplarily, the external input resource volume is the resource volume that each pipe section needs to receive from other pipelines.

[0061] In some embodiments, the external input resource amount includes the external input resource amount of the first cycle and the external input resource amount of the second cycle.

[0062] Exemplarily, the cycle duration of the first cycle is greater than the cycle duration of the second cycle.

[0063] For example, the first period may be in years, and the second period may be in days.

[0064] In some embodiments, the amount of external input resources is determined based on the connection relationship between each pipe segment and the existing pipeline and the resource transportation direction of the existing pipeline in the pipeline network.

[0065] For example, the transport resource direction of the built pipeline is determined based on professional analysis tools, wherein the professional analysis tools may be pipeline flow direction simulation software, fluid dynamics analysis software, and the like.

[0066] Exemplarily, the pipeline network is drawn based on basic information of all existing pipelines and basic information of newly constructed pipelines in the design area.

[0067] Among them, the basic information of the built pipeline includes: the length of the built pipeline, transmission capacity and transmission direction.

[0068] Among them, the basic information of the newly built pipeline includes: the total length of the pipeline, the connection points between the newly built pipeline and the existing pipeline, and the length of the pipe section between the connection points.

[0069] It should be noted that based on the fact that the load rate of existing pipelines in the pipeline network is not lower than the preset load threshold, the connection points between the newly built pipelines and the existing pipelines are allocated to maximize the utilization of the pipelines in the pipeline network and achieve a balance between supply and demand of resources in a certain area.

[0070] In some embodiments, the local uploaded resource volume is the self-produced resource in the design area where each pipe section is located or the resource volume that the storage facility needs to upload to the corresponding pipe section. For example, the local uploaded resource volume can be local self-produced gas, imported LNG resources, gas storage resources, etc. It is understandable that the local self-produced gas usually gives priority to meeting local consumption needs, and the excess resource volume can be uploaded to the pipeline for transmission to distant places in the region or other regions.

[0071] It should be noted that the local uploaded resource volume refers to the remaining resource volume uploaded to the pipeline section after the self-produced resource volume in the design area where the pipeline section is located meets the local consumption resources.

[0072] Exemplarily, the local upload resource amount includes the local upload resource amount of the first period and the local upload resource amount of the second period.

[0073] In some embodiments, the amount of locally consumed resources is the amount of resources that each pipe segment needs to provide to the area where the pipe segment is located, for example, the amount of resources required for production and life of various types of users in the design area.

[0074] It should be noted that the local consumption resource volume refers to the amount of resources that need to be downloaded from the pipe section because the self-produced resources in the design area where the pipe section is located cannot meet the local consumption.

[0075] Exemplarily, the locally consumed resource amount includes the locally consumed resource amount in a first period and the locally consumed resource amount in a second period.

[0076] In some embodiments, the local uploaded resource amount and the local consumed resource amount of each pipe segment are determined based on the change trend of the local historical uploaded resource amount and the local historical consumed resource amount of the design area where the pipe segment is located.

[0077] Exemplarily, the changing trend can be determined based on the following methods: obtaining the local historical uploaded resource quantities and the local historical consumed resource quantities of the pipe section design area; drawing a line graph based on the local historical uploaded resource quantities and the local historical consumed resource quantities; and obtaining the changing trend of the local historical uploaded resource quantities and the local historical consumed resource quantities of the pipe section design area by analyzing the line graph.

[0078] In some embodiments, the amount of resources transferred to the interconnected pipeline is the amount of resources that each pipe segment needs to transfer to the interconnected pipeline, for example, multiple intersecting trunk pipelines in a pipeline network.

[0079] Exemplarily, the amount of resources transferred to the Unicom pipeline includes the amount of resources transferred to the Unicom pipeline in a first cycle and the amount of resources transferred to the Unicom pipeline in a second cycle.

[0080] In some embodiments, the following situations may exist between the external input resource volume, local upload resource volume, local consumption resource volume, and resource volume transferred to the interconnection pipeline of the centralized and distributed pipeline:

[0081] Case 1: A balance is reached between the total amount of external input resources and local uploaded resources in the centralized and distributed pipeline and the amount of local consumed resources, that is, the sum of the external input resources and the local uploaded resources is equal to the local consumption, achieving a balance between resource supply and demand within a certain range.

[0082] It should be noted that local upload resources are preferentially provided to areas that are closer, and if there are any remaining resources, they can be provided to areas that are farther away.

[0083] Case 2: When the total amount of external input resources and local uploaded resources from the distribution pipeline cannot meet the local consumption, that is, the sum of external input resources and local uploaded resources is less than local consumption, the shortfall resources can be transferred to this area through the distribution pipeline connected to the pipeline network in the design area to achieve a balance of resources within a certain range, or by increasing the upload of local LNG resources to achieve a balance of resources within a certain range.

[0084] Case 3: The total amount of external input resources and local uploaded resources of the distribution pipeline is too much. While meeting the local consumption of resources, there are still surplus resources, that is, the sum of the input resources and the local uploaded resources is greater than the local consumption of resources. It is necessary to transfer the excess resources to other areas through the distribution pipeline connected to the pipeline network in the design area, or to achieve resource balance within a certain range by reducing the upload of local LNG resources.

[0085] S203, based on the external input resource volume of each pipe section, the local uploaded resource volume, the local consumed resource volume and the resource volume transferred to the interconnected pipeline, determine the output resource volume of each pipe section node.

[0086] It can be understood that in order to ensure the transmission balance between the distribution pipeline sections, the node output resource volume is equal to the difference between the sum of the external input resource volume and the local uploaded resource volume and the sum of the local consumed resource volume and the resource volume transferred to the interconnected pipeline.

[0087] In some embodiments, the node output resource quantity of the pipe segment satisfies the following formula (1):

[0088] The output resource volume of each pipeline node in the preset period = the external input resource volume in the preset period + the local uploaded resource volume in the preset period - the local consumed resource volume in the preset period - the resource volume transferred to the interconnected pipeline in the preset period Formula (1)

[0089] The preset period is the first period or the second period.

[0090] In some embodiments, when the first period is a year, the external input resource amount of the first period may be the external annual input resource amount; the local uploaded resource amount of the first period may be the local annual uploaded resource amount; the local consumed resource amount of the first period may be the local annual consumed resource amount; the resource amount transferred to the connecting pipeline in the first period may be the annual transferred resource amount to the connecting pipeline; the segment node output resource amount of the first period may be the segment node annual output resource amount.

[0091] In some embodiments, when the second period is daily, the external input resource amount of the second period may be the external daily input resource amount; the local upload resource amount of the second period may be the local daily upload resource amount; the local consumption resource amount of the second period may be the local daily consumption resource amount; the resource amount transferred to the connecting pipeline in the second period may be the daily transfer to the connecting pipeline; the segment node output resource amount of the second period may be the segment node daily output resource amount.

[0092] Exemplarily, the local daily resource consumption is the local high monthly average daily resource consumption.

[0093] Exemplarily, the local daily upload resource amount is the local high monthly average daily upload resource amount.

[0094] Exemplarily, the daily amount of resources transferred to the Unicom pipeline is the higher monthly average daily amount of resources transferred to the Unicom pipeline.

[0095] Exemplarily, the external daily input resource volume is the external high monthly average daily input resource volume. For example, assuming that the month with the highest monthly average input resource volume of a section of pipeline is November, and the monthly average input resource volume in November is 2.1 billion cubic meters, the daily input resource volume is 0.7 billion cubic meters.

[0096] In some embodiments, the resource output of each pipeline segment node is the resource output of the nodes before and after the pipeline segment, for example, the starting point of the first pipeline segment and the node connected to the second pipeline segment.

[0097] Exemplarily, the node output resource amount of each pipe section selects the node output resource amount with the larger node output resource amount as the node output resource amount of the pipe section.

[0098] Exemplarily, the node output resource amount includes the node output resource amount of the first cycle and the node output resource amount of the second cycle.

[0099] Exemplarily, the node output resource amount in the first period may be the node annual output resource amount.

[0100] Exemplarily, the node output resource amount in the second period may be the node daily output resource amount.

[0101] S204: Determine the overall design transport capacity of the distribution pipeline based on the output resource quantity of each pipeline segment node.

[0102] In some embodiments, the overall designed transport capacity of the distribution pipeline includes the overall designed annual transport capacity and the overall designed daily transport capacity.

[0103] Exemplarily, the overall designed annual transmission capacity is the maximum amount of resources that can be transmitted annually by the distribution pipeline.

[0104] Exemplarily, the overall designed daily throughput is the maximum value of the daily transmission resources of the distribution pipeline.

[0105] One possible implementation method is to determine the overall designed annual transmission capacity of the distribution pipeline based on the output resource volume of each pipeline segment node, the length of each pipeline segment and the total length of the distribution pipeline. The specific steps refer to the following step S2041 and will not be repeated here.

[0106] Another possible implementation method is to determine the daily output resource volume of the pipeline segment node with the largest average daily output resource volume in the highest month for all pipeline segments of the distribution pipeline in the design area as the overall design daily output volume of the distribution pipeline. For specific steps, refer to the following step S2042 and will not be repeated here.

[0107] S205. Design the pipeline based on the overall design delivery capacity of the distribution pipeline.

[0108] It should be noted that the design of pipelines based on the overall design delivery capacity of the distribution pipeline is first to comprehensively analyze the amount of resources that need to be evacuated by the distribution pipeline, including external input resources and local uploaded resources; then, based on the distribution of other pipelines in the area where the distribution pipeline passes, reasonably determine the amount of local resource consumption; finally, based on the load conditions of other pipelines connected to the distribution pipeline, reasonably allocate the amount of resources transferred to the connected pipeline, so as to achieve the purpose of resource evacuation. Since the flow direction and flow rate between the sections of the distribution pipeline will change with time and the external input resources and local uploaded resources, the node output resource volume of each section of the distribution pipeline in the first and second cycles during the operation period is analyzed, and the design delivery volume of the entire distribution pipeline is comprehensively determined based on the output resource volume of each section node, such as Figure 3 As shown, this is a pipeline network planning diagram provided by the present application. By connecting with an existing pipeline (such as a resource-based pipeline), the distribution pipeline can transport the resources of the existing pipeline (such as a resource-based pipeline) to the design area. By connecting with other cross-regional pipelines in the design area, the excess resources can be transferred to other areas. It should be noted that the local LNG resource uploading pipeline is a resource-based pipeline.

[0109] It should be noted that the pipeline design is based on the overall design annual transmission capacity and the overall design daily transmission capacity of the distribution type pipeline, and the diameter of the distribution type pipeline is reasonably determined. For example, the larger the overall design annual transmission capacity, the larger the diameter of the distribution type pipeline, the larger the overall design daily transmission capacity, and the stronger the resource evacuation capacity of the distribution type pipeline. There is no conversion relationship between the design annual transmission capacity and the design daily transmission capacity of the distribution type pipeline.

[0110] It can be understood that the distributed pipeline design method provided in the embodiment of the present application determines the output resource amount of each pipe section node based on the external input resource amount, local uploaded resource amount, local consumed resource amount, and resource amount transferred to the connected pipeline of each pipe section, thereby improving the accuracy of the overall design delivery amount, and determining the overall design delivery amount of the pipeline based on the output resource amount of each pipe section node, so that the distributed pipeline can be fully utilized, thereby improving the utilization efficiency of the distributed pipeline; the overall design delivery amount determines the design scale of the distributed pipeline, characterizes the resource collection and evacuation capacity of the distributed pipeline, and improves the resource guarantee and allocation capacity of the area where the distributed pipeline is located.

[0111] In some embodiments, when the first cycle is one year, in order to ensure the transmission balance between the distribution pipeline sections, the node output resource volume is equal to the sum of the external input resource volume and the local uploaded resource volume and the difference between the local consumed resource volume and the resource volume transferred to the interconnected pipeline.

[0112] Exemplarily, the node output resource quantity of the pipe section satisfies the following formula (2):

[0113] The output resource volume of each pipeline node in the preset period = the external input resource volume in the preset period + the local uploaded resource volume in the preset period - the local consumed resource volume in the preset period - the resource volume transferred to the interconnected pipeline in the preset period Formula (2)

[0114] Exemplarily, the design area of ​​the distribution pipeline and the connection status with the resource pipeline in the design area are determined; based on the resource delivery direction and delivery volume of the connected pipeline, the external annual input resource volume and the local annual uploaded resource volume of the distribution pipeline in each year are determined.

[0115] For example, based on the statistical data of local historical annual resource consumption, the local annual resource consumption of each pipe section of the distribution pipeline in the future years is predicted.

[0116] Exemplarily, the design area of ​​the distribution pipeline and the connectivity with other distribution pipelines in the design area are determined; based on the transportation direction and resource volume of other distribution pipelines, and taking into account load balancing to meet hydraulic matching (i.e., load balance and stable pressure of each pipeline), the annual resource transfer volume to other distribution pipelines is determined.

[0117] In some embodiments, when the second cycle is daily, in order to meet the transmission balance of resources, the output resource volume of each section node of the distributed pipeline is equal to the difference between the sum of the external input resource volume and the local uploaded resource volume and the local consumed resource volume and the resource volume transferred to the interconnected pipeline.

[0118] For example, in some embodiments, the daily output resource volume of each pipeline node may satisfy the following formula (3):

[0119] Node daily output resource volume = external daily input resource volume + local daily upload resource volume - local daily consumption resource volume - daily transfer volume to the interconnected pipeline Formula (3)

[0120] Exemplarily, the design area of ​​the distribution pipeline and the connection status with the resource pipeline in the design area are determined; based on the resource delivery direction and delivery volume of the connected pipeline, the external input resource volume and local uploaded resource volume of the distribution pipeline on the highest monthly average day of each year are determined.

[0121] For example, based on the statistical data of the local historical high monthly average daily resource consumption, the local high monthly average daily resource consumption of each section of the distribution pipeline in the future years is predicted.

[0122] Exemplarily, determine the design area of ​​the distribution pipeline and the connectivity with other distribution pipelines in the design area; based on the delivery direction and delivery volume of other distribution pipelines, and taking into account load balancing and hydraulic matching, determine the high monthly average daily resource transfer volume to other distribution pipelines in each year.

[0123] In some embodiments, when the first period is a year, the node output resource volume of each pipeline section includes the annual output resource volume; and the overall design transmission volume of the distribution pipeline includes the design annual transmission volume.

[0124] Exemplarily, the above step S204 can be specifically implemented as the following step S2041.

[0125] S2041. Determine the overall design annual transmission capacity of the distribution pipeline based on the annual output resource volume of each pipeline segment node, the length of each pipeline segment and the total length of the distribution pipeline.

[0126] For example, the overall design annual capacity of the distribution pipeline satisfies the following formula (4):

[0127]

[0128] Among them, Q y It represents the overall designed annual capacity of the distribution pipeline, Q i represents the annual output resource of the i-th pipeline node, L i It represents the length of the i-th pipe section, and L represents the total length of the distribution pipeline.

[0129] For example, see Figure 4 , assuming that the distribution pipeline runs from resource point 1 to resource point 2, passing through 4 download points and 2 transfer points. The section from resource point 1 to transfer point 1 is called section 1, the section from transfer point 1 to transfer point 2 is called section 2, and the section from transfer point 2 to resource point 2 is called section 3. Among them, the length of section 1 is 200 kilometers, the length of section 2 is 400 kilometers, and the length of section 3 is 700 kilometers. The average annual input resource volume of section 1 is 26 billion cubic meters, the average annual input resource volume of section 2 is 20 billion cubic meters, and the average annual input resource volume of section 3 is 22 billion cubic meters / year.

[0130] For example, based on the above formula (4), the overall design annual transmission capacity of the distribution pipeline is determined to be 22 billion cubic meters.

[0131] In some embodiments, the output resource volume of each pipeline segment node includes the high monthly average daily output resource volume; and the overall designed transport volume of the distribution pipeline includes the designed daily transport volume.

[0132] Exemplarily, the above step S204 can be specifically implemented as the following step S2042.

[0133] S2042. For all pipeline sections of the distribution type pipeline within the design area, the maximum average monthly daily output resource volume of each pipeline section node shall be determined as the overall design daily output volume of the distribution type pipeline.

[0134] For example, assuming that the high monthly average daily output resource volume of pipe section 1 is 70 million cubic meters, the high monthly average daily output resource volume of pipe section 2 is 60 million cubic meters, and the high monthly average daily output resource volume of pipe section 3 is 80 million cubic meters, the output resource volume of the pipe section node with the largest high monthly average daily output resource volume is used as the overall design daily output volume of the distribution type pipeline. Based on this, the overall design daily output volume of the distribution type pipeline is 80 million cubic meters / day.

[0135] It can be understood that the embodiment of the present application provides a distributed pipeline design method. Through the distributed pipeline design method provided by the present application, the establishment of a pipeline network within a certain range is accelerated, the external input resource volume, local uploaded resource volume, local consumed resource volume and the transfer volume to the interconnecting pipeline of each pipe section in the distributed pipeline design area are comprehensively analyzed, and the overall design scale of the distributed pipeline is comprehensively determined, which makes up for the gap that the design output of the distributed pipeline cannot be determined.

[0136] like Figure 5 As shown, it is another distributed pipeline planning diagram provided by this application.

[0137] In some embodiments, the distribution pipeline receives input resources from the existing pipelines (western and northern pipelines) from Z1, and receives local uploaded resources (i.e. local LNG resource uploading) from point Z2. The distribution pipeline has 5 connection points with other pipelines (L1, L2, L3, L4, L5), and there are 5 regional resource consumption points (i.e. local resource consumption, including: S1, S2, S3, S4, S5).

[0138] Exemplarily, the length of the above-mentioned distribution pipeline is 700 kilometers, among which Z1 to L1 is regarded as segment a, and the length of segment a is 260 kilometers; L1 to L2 is regarded as segment b, and the length of segment b is 40 kilometers; L2 to L3 is regarded as segment c, and the length of segment c is 230 kilometers; L3 to L4 is regarded as segment d, and the length of segment d is 70 kilometers; L4 to L5 is regarded as segment e, and the length of segment e is 50 kilometers; L5 to Z2 is regarded as segment f, and the length of segment f is 50 kilometers.

[0139] Exemplarily, the annual output resource volume of each pipeline section node is determined based on the annual external input resource volume of each pipeline section, the annual local uploaded resource volume, the annual local consumed resource volume, and the annual resource volume transferred to the interconnected pipeline.

[0140] For example, as shown in Table 1, in a certain year (usually the year with the largest annual output analyzed year by year), the maximum annual output resource volume of the node of section a is 18.5 billion cubic meters, that of section b is 17.5 billion cubic meters, and so on. The maximum annual output resource volume of the node of section f is 5 billion cubic meters.

[0141] Table 1 Maximum annual output resources of each pipeline node

[0142] Pipe segment Annual output of resources (billion cubic meters / year) Pipe segment a 185 Pipe segment b 175 Pipe segment c 140 Pipe segment d 85 Pipe segment 35 Pipe segment f 50

[0143] For example, based on formula (4), the overall design annual transmission capacity of the distribution pipeline is determined to be 14 billion cubic meters per year.

[0144] Exemplarily, the high monthly average daily output resource volume of each pipeline section node is determined based on the high monthly average daily external input resource volume of each pipeline section, the high monthly average daily local upload resource volume, the high monthly average daily local consumption resource volume, and the high monthly average daily transfer resource volume to the interconnecting pipeline.

[0145] For example, as shown in Table 2, in a certain year (usually the year with the largest average monthly daily output in the year-by-year analysis), the average monthly daily output resource volume of the node of pipeline section a is 49 million cubic meters / day, the average monthly daily output resource volume of the node of pipeline section b is 43 million cubic meters / day, and so on. The average monthly daily output resource volume of the node of pipeline section f is 12 million cubic meters / day.

[0146] Table 2 Maximum monthly average daily output resource of each pipeline node

[0147]

[0148]

[0149] Exemplarily, the maximum average monthly daily output resource volume of each pipeline section node is determined as the overall design daily output volume of the distribution type pipeline. Based on this, the overall design daily output volume of the distribution type pipeline is 49 million cubic meters per day.

[0150] Exemplarily, the distribution pipeline design is performed based on the overall designed annual throughput and the overall designed daily throughput.
