[0048] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0049] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0050] Figure 1 FIG. 1 is a crude oil scheduling process flow chart of a refinery enterprise according to an exemplary embodiment. Figure 1 As shown in the figure, a certain oil refinery purchases crude oil and transports it to a certain wharf via tanker; after the tanker safely berths at the port, the crude oil is unloaded into multiple suitable wharf tanks; the crude oil in the wharf tank has two transportation routes: one transportation route is that the crude oil enters the transfer tank through a shorter oil pipeline (i.e., non-long-distance pipeline), and the other transportation route is that the crude oil enters the plant tank through a longer oil pipeline (i.e., long-distance pipeline); the crude oil in the transfer tank can also enter the plant tank through the long-distance pipeline; finally, the crude oil in the plant tank enters the distillation unit for processing. The non-long-distance pipeline connecting the wharf tank and the transfer tank is usually short (e.g., 11 km), and the transportation delay effect of the non-long-distance pipeline can be ignored, but the long-distance pipeline supplying the plant tank is usually long (e.g., 163 km) and has a large volume (e.g., 46,000 m 3 ), it takes a long time (for example, more than 20 hours) for crude oil to leave the long-distance pipeline after entering the long-distance pipeline. Therefore, the crude oil transportation problem of the oil refinery is a complex problem involving long-distance pipeline transportation.

[0051] In view of this, the present disclosure provides a method, device, medium and electronic equipment for transporting crude oil in a long-distance pipeline.

[0052] Figure 2 FIG. 1 is a flow chart showing a long-distance pipeline crude oil transportation according to an exemplary embodiment. Figure 2 As shown, the long-distance pipeline crude oil transportation method may include the following S201 and S202.

[0053] In S201, the pipeline section information of the initial oil storage in the long-distance pipeline, the oil receiving operation parameters of the long-distance pipeline, and the destination of the incoming oil are obtained.

[0054] In the present disclosure, the long-distance pipelines involved in the current crude oil scheduling project may be one or more, and the present disclosure does not make any specific limitation.

[0055] Before the current crude oil scheduling project starts, it is assumed that all long-distance pipelines have full oil reserves, and the initial pipeline oil reserves are the oil reserves in the long-distance pipelines at the start of scheduling. Among them, the same type of crude oil with continuous distribution and the same destination in the initial pipeline oil reserves is divided into a pipeline segment (i.e., crude oil segment). In this way, the initial pipeline oil reserves are divided into one or more pipeline segments, wherein the pipeline segment information includes the initial volume, initial oil type, and oil destination (i.e., downstream equipment) of each pipeline segment contained in the initial pipeline oil reserves, such as Figure 1 As shown, the downstream equipment of the long-distance pipeline may include plant tanks and distillation units.

[0056] As shown in Table 1 below, the initial pipeline oil storage includes three pipeline segments, among which CT09, CT08 and CT02 are all plant tanks.

[0057] Table 1 Pipeline segment information of initial oil storage

[0058]

[0059] When formulating a long-distance pipeline oil collection plan, oil refineries have basically determined the destination of the incoming oil (i.e., the destination of the incoming oil is known). The long-distance pipeline oil collection plan (known quantity) refers to the operation plan for the crude oil to enter the long-distance pipeline, which may include the operation time (including the first start time and the first end time), crude oil delivery volume, the first delivery rate, the type of oil delivered, etc.

[0060] For ease of understanding, the oil collection process of a long-distance pipeline receiving the same type of oil at the same rate and planned to go to the same single downstream equipment is recorded as one oil collection operation. According to the definition of the oil collection operation, the oil collection scheme of the long-distance pipeline can be divided into multiple oil collection operations, and the first start time, first end time, oil collection volume (i.e., delivery volume), first delivery rate, and delivered oil type of each oil collection operation can be obtained, that is, the oil collection operation parameters of the long-distance pipeline are obtained. That is, the oil collection operation parameters include the first start time, first end time, oil collection volume, first delivery rate, and delivered oil type of each oil collection operation.

[0061] As shown in Table 2 below, the long-distance pipeline includes 16 oil collection operations, among which CT01 to CT09 are all plant tanks, and the first start time and the first end time are both relative times starting from the scheduling start time.

[0062] Table 2 Oil receiving operation parameters and destination of incoming oil in long-distance pipelines

[0063]

[0064] return Figure 2 In S202, the oil delivery operation parameters of the long-distance pipeline are determined according to the pipeline segment information, the oil receiving operation parameters and the destination of the incoming oil.

[0065] In the present disclosure, the oil delivery operation parameters may include the second start time, the second end time, the oil delivery volume, the second delivery rate, the oil delivery destination and the oil type of each outgoing oil leaving the long-distance pipeline, wherein the outgoing oil is the pipeline section with initial storage oil or the incoming oil leaving the long-distance pipeline.

[0066] For example, according to the pipeline segment information of the initial oil storage shown in Table 1 above, and the oil receiving operation parameters and the destination of the incoming oil of the long-distance pipeline shown in Table 2 above, the oil delivery operation parameters of the long-distance pipeline shown in Table 3 below can be obtained. Among them, the second start time and the second end time are relative times starting from the scheduling start time.

[0067] Table 3 Oil delivery operation parameters of long-distance pipeline

[0068]

[0069] In the above technical scheme, the pipeline section information of the initial oil storage in the long-distance pipeline, the oil collection operation parameters of the long-distance pipeline and the destination of the incoming oil are first obtained; then, the oil delivery operation parameters of the long-distance pipeline are determined according to the pipeline section information, the oil collection operation parameters and the destination of the incoming oil. In this way, as long as the oil collection plan of the long-distance pipeline is given and the destinations of the crude oil in the initial pipeline and the incoming oil are allocated, the oil delivery plan of the long-distance pipeline can be automatically compiled. Therefore, the crude oil transportation plan of the long-distance pipeline can be quickly and automatically compiled without manual intervention, which not only reduces the scheduling threshold, but also reduces the work intensity of personnel and improves the productivity of the enterprise, which is of great significance for achieving stable production and economic production. In addition, the rationality of the long-distance pipeline oil collection plan and the destination of the crude oil in the pipeline can be verified according to the oil delivery operation parameters of the long-distance pipeline. In addition, the present disclosure can solve the problem of crude oil transportation in long-distance pipelines and realize efficient transportation of crude oil in long-distance pipelines. Crude oil is usually corrosive and will corrode the pipeline if it stays in the long-distance pipeline for a long time. Therefore, the present disclosure can solve the technical problem of inhibiting corrosion of long-distance pipelines.

[0070] The following is a detailed description of the specific implementation method of determining the oil delivery operation parameters of the long-distance pipeline according to the pipeline segment information, the oil receiving operation parameters and the destination of the incoming oil in the above S102. Figure 3 It is realized by S301~S313 shown in:

[0071] In S301, let i=1, o=1, no o =1.

[0072] In this disclosure, i represents the i-th oil collection operation of the long-distance pipeline, o represents the o-th section of the long-distance pipeline oil, and no o Indicates the oil outlet of section o oAmong them, because the long-distance pipeline may stop transmission, change speed, etc., each section of the outgoing oil may leave the long-distance pipeline multiple times, with multiple departure start times and end times, that is, multiple second start times and second end times. For this reason, the variable no is set o To indicate the different start and end times of the oth section of the outgoing oil.

[0073] In addition, each oil receiving operation of the long-distance pipeline is numbered starting from 1 according to the order in which the operations are executed; the outgoing oil is arranged according to the order in which it enters the long-distance pipeline, that is, the outgoing oil is numbered starting from 1 according to the order in which the outgoing oil enters the long-distance pipeline.

[0074] In S302, the first start time of the i-th oil collection operation is determined as the no. o The second starting time of the first delivery is to determine the first delivery rate of the i-th oil collection operation as the no. o The second delivery rate of the secondary delivery.

[0075] Right now,

[0076] Among them, tsin i is the first start time of the i-th oil recovery operation, The oil outlet of section o is o The second start time of the second delivery, fin i is the first delivery rate of the i-th oil recovery operation, The oil outlet of section o is o The second delivery rate of the secondary delivery.

[0077] In S303, it is determined whether the remaining outgoing oil volume of the o-th section outgoing oil is greater than the remaining incoming oil volume of the i-th section incoming oil corresponding to the i-th oil collection operation.

[0078] In the present disclosure, the remaining outlet oil volume of the oth section outlet oil vsout o The initial value is vout o , that is, vsout o =vout o , vout o is the oil collection volume or initial volume of the oth section of the outgoing oil. When the oth section of the outgoing oil is a pipeline segment, vsout o The initial value of vsout is the initial volume of the outgoing oil of the oth section. When the outgoing oil of the oth section is the incoming oil leaving the long-distance pipeline, vsout o The initial value of is the oil collection volume of the oth section of the outlet oil.

[0079] The i-th oil collection operation corresponds to the i-th section of the long-distance pipeline incoming oil, where the remaining incoming oil volume of the i-th section of the incoming oil vsin i is the volume of the i-th section of the oil that will enter the long-distance pipeline, vsin i The initial value of is the oil recovery volume vin of the i-th oil recovery operation i , that is, vsin i =vin i .

[0080] Due to the "first in, first out" (i.e. "plug flow") movement characteristics of the long-distance pipeline, the long-distance pipeline will first transport the first pipeline section to the downstream equipment, then the second pipeline section, and so on, until the crude oil in the pipeline section is completely output, that is, the initial pipeline oil is completely pushed out, the long-distance pipeline begins to transport the first section of incoming oil to the downstream equipment, then the second section of incoming oil, and so on, among which the pipeline sections are numbered from 1 according to the order of entering the long-distance pipeline.

[0081] If the remaining outgoing oil volume of the o-th section outgoing oil is not greater than the remaining incoming oil volume of the i-th section incoming oil corresponding to the i-th oil collection operation, it indicates that the remaining incoming oil of the i-th section incoming oil can completely push out the remaining outgoing oil of the o-th section outgoing oil. At this time, the following S304 to S306 can be executed; if the remaining outgoing oil volume of the o-th section outgoing oil is greater than the remaining incoming oil volume of the i-th section incoming oil corresponding to the i-th oil collection operation, it indicates that the remaining incoming oil of the i-th section incoming oil cannot completely push out the remaining outgoing oil of the o-th section outgoing oil. That is, the remaining incoming oil of the i-th section incoming oil and the incoming oil of the subsequent sections are required to completely push out the remaining outgoing oil of the o-th section outgoing oil. At this time, the following S310 to S312 can be executed.

[0082] In S304, the volume of the o-th section outlet oil is determined as the volume of the o-th section outlet oil. o The volume of the first delivery is based on the oil of the first section. o The second start time of the first delivery, the no. o The second delivery rate of the first delivery and the no. o The volume of the oil delivered at the first delivery is determined by the oil outlet of the first section. o The second end time of the second delivery.

[0083] In the present disclosure, when the remaining outgoing oil volume of the o-th segment outgoing oil is not greater than the remaining incoming oil volume of the i-th segment incoming oil corresponding to the i-th oil collection operation, it indicates that the remaining incoming oil of the i-th segment incoming oil can completely push out the remaining outgoing oil of the o-th segment outgoing oil. Therefore, the o-th segment outgoing oil is o The volume of the delivery is equal to the volume of the oil in the oth section, that is,

[0084] For example, the oil of the oth section outlet is o The second end time of the delivery

[0085]

[0086] In S305, the remaining outgoing oil volume of the oth segment outgoing oil and the remaining incoming oil volume of the ith segment incoming oil are updated, and o is incremented by 1, and no o =1.

[0087] Since the remaining oil in the i-th section of the inlet oil can completely push out the remaining oil in the o-th section of the outlet oil, the remaining oil volume of the o-th section of the outlet oil vsout o =0, that is, the remaining amount of the o-th section of the outgoing oil after the update is 0. At this time, it indicates that the complete oil payment plan for the o-th section of the outgoing oil has been determined. After that, the oil payment plan for the o+1-th section of the outgoing oil begins to be determined, that is, let o add 1, no o =1.

[0088] In addition, the remaining oil volume of the i-th section of the line oil That is, the remaining amount of incoming oil in the i-th section after updating is

[0089] In S306, it is determined whether the remaining amount of incoming line oil of the i-th section incoming line oil obtained after update is equal to zero.

[0090] In the present disclosure, if the remaining incoming oil amount of the i-th section incoming oil obtained after the update is equal to zero, it indicates that the remaining incoming oil of the i-th section incoming oil can just push out the remaining outgoing oil of the o-th section outgoing oil. At this time, it can be determined whether the i-th section incoming oil is the last section incoming oil of the long-distance pipeline, that is, the following S307 is executed; if the remaining incoming oil amount of the i-th section incoming oil obtained after the update is not equal to zero, that is, the remaining incoming oil amount of the i-th section incoming oil obtained after the update is greater than zero, it indicates that the remaining incoming oil of the i-th section incoming oil can not only completely push out the remaining outgoing oil of the o-th section outgoing oil, but also can be used to push out part or all of the outgoing oil of the o-th section outgoing oil (in S305, o has been added by 1), at this time, the following S309 can be executed, and then return to the above S303.

[0091] In S307, it is determined whether i is equal to the total number of oil collection times.

[0092] If i is not equal to the total number of oil collection times, that is, i is less than the total number of oil collection times, it indicates that the i-th section of incoming oil is not the last section of incoming oil of the long-distance pipeline. At this time, it is necessary to use the i+1-th section of incoming oil to push out the o-th section of outgoing oil (in S305, o has been added by 1), so i is added by 1, that is, the following S308 is executed, and then it returns to the above S302 to continue executing until i is equal to the total number of oil collection times; if i is equal to the total number of oil collection times, it indicates that the i-th section of incoming oil is the last section of incoming oil of the long-distance pipeline. At this time, it indicates that all the incoming oil of the long-distance pipeline has entered the long-distance pipeline, and the long-distance pipeline oil delivery is completed, that is, the complete oil delivery plan of the long-distance pipeline is obtained, and at this time, the method flow can be ended.

[0093] In S308, i is incremented by 1.

[0094] In S309, the oil of the outlet of the o-1 section is o-1 The second end time of the second delivery is determined as the no. o The second starting time of the ith delivery, and the first delivery rate of the ith oil collection operation is determined as the no. o The second delivery rate of the secondary delivery.

[0095] In the present disclosure, if the remaining amount of the incoming line oil of the i-th section after updating is not equal to zero, it means that the remaining incoming line oil of the i-th section of the incoming line oil can not only completely push out the remaining outgoing line oil of the o-1-th section of the outgoing line oil, but can also be used to push out part or all of the outgoing line oil of the o-th section of the outgoing line oil. At this time, the no. o-1 The second end time of the second delivery is determined as the no. o The second starting time of the ith delivery, and the first delivery rate of the ith oil collection operation is determined as the no. o Then, according to the remaining outgoing oil volume of the oth section outgoing oil and the remaining incoming oil volume of the ith section incoming oil obtained after the update, determine the no. o The volume of the first delivery and the volume of the oil outlet of the oth section o The second end time of the second delivery, that is, returns to the above S303.

[0096] In S310, the remaining amount of the incoming oil of the i-th section is determined as the no. o The volume of the oil delivered each time, and the first end time of the i-th oil collection operation is determined as the no. o The second end time of the second delivery.

[0097] If the remaining outgoing line oil volume of the o-th section outgoing line oil is greater than the remaining incoming line oil volume of the i-th section incoming line oil corresponding to the i-th oil collection operation, it means that the remaining incoming line oil of the i-th section incoming line oil cannot completely push out the remaining outgoing line oil of the o-th section outgoing line oil, that is, it is necessary to use the remaining incoming line oil of the i-th section incoming line oil and the incoming line oil of the subsequent sections to completely push out the remaining outgoing line oil of the o-th section outgoing line oil. At this time, the remaining incoming line oil volume of the i-th section incoming line oil is determined as the no. o The volume delivered each time is The first end time of the i-th oil collection operation is determined as the no. o The second end time of the delivery, i.e. Among them, tein i is the first end time of the i-th oil recovery operation.

[0098] In S311, the remaining outgoing oil volume of the o-th stage outgoing oil and the remaining incoming oil volume of the i-th stage incoming oil are updated.

[0099] Since the remaining incoming oil of the i-th section cannot completely push out the remaining outgoing oil of the o-th section, it is necessary to use the remaining incoming oil of the i-th section and the incoming oil of the subsequent sections to completely push out the remaining outgoing oil of the o-th section. Therefore, the remaining incoming oil amount of the i-th section is vsin i =0, at this time, it can be determined whether the i-th section of incoming oil is the last section of incoming oil of the long-distance pipeline, that is, the following S312 is executed.

[0100] Remaining oil volume of the oth section of the outlet oil That is, the remaining amount of outlet oil in the oth section after updating is

[0101] In S312, it is determined whether i is equal to the total number of oil collection times.

[0102] If i is not equal to the total number of oil collections, that is, i is less than the total number of oil collections, it means that the i-th section of incoming oil is not the last section of the long-distance pipeline. At this time, the i+1-th section of incoming oil is needed to push out the remaining outgoing oil of the o-th section of outgoing oil, that is, the o-th section of outgoing oil needs to leave the long-distance pipeline in multiple times. Therefore, i is increased by 1, no oAlso add 1, that is, execute the following S313, then return to the above S302 to continue executing until i is equal to the total number of oil collection times, wherein, after returning to S302 and executing S303, it is to determine whether the remaining outgoing oil volume of the oth section of the outgoing oil obtained after the update is greater than the remaining incoming oil volume of the i-th section of the incoming oil corresponding to the i-th oil collection operation; if i is equal to the total number of oil collection times, it indicates that the i-th section of the incoming oil is the last section of the incoming oil of the long-distance pipeline. At this time, it indicates that all the incoming oil of the long-distance pipeline has entered the long-distance pipeline, and the long-distance pipeline oil delivery is completed, that is, the complete oil delivery plan of the long-distance pipeline is obtained, and at this time, the method flow can be ended.

[0103] In S313, let i and no o Add 1 to each.

[0104] In addition, the destination of each delivery of the o-th section of the outgoing oil is the oil storage destination or the incoming oil destination of the o-th section of the outgoing oil, wherein, when the o-th section of the outgoing oil is a pipeline section, the destination of each delivery of the o-th section of the outgoing oil is the oil storage destination of the o-th section of the outgoing oil; when the o-th section of the outgoing oil is the incoming oil leaving the long-distance pipeline, the destination of each delivery of the o-th section of the outgoing oil is the incoming oil destination of the o-th section of the outgoing oil.

[0105] The delivered oil type for each delivery of the o-th section of the outgoing oil is the initial oil type or the delivery oil type of the o-th section of the outgoing oil, wherein, when the o-th section of the outgoing oil is a pipeline section, the delivered oil type for each delivery of the o-th section of the outgoing oil is the initial oil type of the o-th section of the outgoing oil, and when the o-th section of the outgoing oil is the incoming oil leaving the long-distance pipeline, the delivered oil type for each delivery of the o-th section of the outgoing oil is the delivery oil type of the o-th section of the outgoing oil.

[0106] In addition, the oil payment plans for each outlet oil obtained through the above S301 to S313 are relatively scattered. In order to make the oil payment plans clearer and more reasonable, the obtained oil payment plans can be sorted and sorted. Specifically, the above S202 can also include the following two steps:

[0107] If i is equal to the total number of oil collections, the oil delivery operations of the long-distance pipeline are uniformly numbered according to the order in which the outgoing oil leaves the long-distance pipeline and the order in which each outgoing oil is delivered;

[0108] Two oil delivery operations with the same second delivery rate, delivery destination and delivery oil type and adjacent delivery operation times are merged.

[0109] In the present disclosure, adjacent operation times means that the end time of the d-th oil delivery operation is the same as the start time of the d+1-th oil delivery operation; uniformly numbering the oil delivery operations of the long-distance pipeline means that for each section of outgoing oil, the double-layer structure information of L transportation operations of the section of outgoing oil is converted into the single-layer structure information of L oil delivery operations.

[0110] For example, the long-distance pipeline includes three sections of outgoing oil, wherein the first section of outgoing oil is a pipeline section, which is M02 oil and is transported once. The second start time of the first delivery of the first section of outgoing oil is 0.00h, the second end time is 11.16h, and the second delivery rate is 2100m 3 / h, the oil delivery destination is plant tank CT08, the oil delivery volume is 23443m 3 The second section of the outgoing oil is the incoming oil, which is M02 oil, and is transported once. The second start time of the first transport of the second section of the outgoing oil is 11.16h, the second end time is 19.47h, and the second transport rate is 2100m 3 / h, the oil delivery destination is plant tank CT08, the oil delivery volume is 17441m 3 The third section of the outgoing oil is the incoming oil, which is M08 oil and is transported in two times. The second start time of the first delivery of the third section of the outgoing oil is 25.71h, the second end time is 46.82h, and the second delivery rate is 2100m 3 / h, the oil delivery destination is the plant tank CT01, and the oil delivery volume is 44320m 3 The second start time of the second delivery of the third section of the oil is 46.82h, the second end time is 48.58h, and the second delivery rate is 2100m 3 / h, the oil delivery destination is plant tank CT06, and the oil delivery volume is 3690m 3 According to the order in which the three sections of outgoing oil leave the long-distance pipeline and the order in which each outgoing oil is delivered each time, the oil delivery operations of the long-distance pipeline are integrated (ie, uniformly numbered), and the oil delivery sequence shown in Table 4 is obtained.

[0111] Among them, the second delivery rate, oil delivery destination and oil delivery oil type of the first delivery of the first section outlet oil and the first delivery of the second section outlet oil are the same, and the oil delivery operation time is adjacent. Therefore, the first delivery of the first section outlet oil and the first delivery of the second section outlet oil can be combined to obtain the oil delivery operation parameters shown in Table 5 below.

[0112] Table 4: Operation parameters of long-distance pipeline oil delivery after unified numbering

[0113]

[0114] Table 5: Combined long-distance pipeline delivery operation parameters

[0115]

[0116] In addition, after determining the oil delivery operation parameters of the long-distance pipeline, the oil storage distribution in the long-distance pipeline at the end of the current crude oil scheduling project can also be determined based on the parameters, that is, the end-of-period pipeline oil storage, for the next crude oil scheduling project. Specifically, the above method can also include the following steps:

[0117] The crude oil section in the incoming oil, excluding the outgoing oil, is determined as the end-of-term pipeline inventory of the long-distance pipeline.

[0118] For example, based on the pipeline segment information of the initial oil storage in the pipeline shown in Table 1 above, and the oil receiving operation parameters and the destination of the incoming oil of the long-distance pipeline shown in Table 2 above, the oil delivery operation parameters of the long-distance pipeline shown in Table 3 above and the distribution information of the oil storage in the pipeline at the end of the period of the long-distance pipeline shown in Table 6 below can be obtained.
