Description

Technical Field

[0001] The present invention relates to the technical field of finished oil pipeline transportation, and in particular to a method and device for determining oil transportation difference of a finished oil pipeline. Background Art

[0002] Finished oil is produced and processed from crude oil, and can be divided into petroleum fuel, petroleum solvents and chemical raw materials, lubricants, paraffin, petroleum asphalt, petroleum coke, etc. Pipeline transportation is one of the most important modes of transportation for finished oil. Pipeline transportation generally uses sequential transportation to continuously transport multiple batches of different types of oil products to improve transportation efficiency. In the transportation process of finished oil, it is usually necessary to determine the oil delivery difference of finished oil (abbreviated as delivery difference), that is, to determine the difference between the input and output of finished oil. The delivery difference is an important economic indicator for evaluating the task of finished oil transportation.

[0003] In the related art, the corresponding transmission difference is usually determined by the oil volume of the output pipeline, the oil sales volume of the output pipeline and the oil storage volume of the pipeline within a time period. Since the pipeline is long and the oil storage volume of the pipeline is related to multiple parameters such as the physical pipe capacity of the pipeline, the oil product interface, temperature, pressure, density, etc., the technical personnel are unable to accurately determine the oil storage volume of the pipeline within a time period, resulting in the inability to accurately determine the transmission difference, which in turn affects the accuracy of the statistical analysis of the finished oil transportation process data.

[0004] Therefore, there is an urgent need for a method and device for determining the oil delivery difference of a finished oil pipeline to accurately determine the delivery difference of the finished oil, thereby providing support for the statistical analysis of the subsequent finished oil transportation process data. Summary of the invention

[0045] Finished oil is produced and processed from crude oil, and can be divided into petroleum fuel, petroleum solvents and chemical raw materials, lubricants, paraffin, petroleum asphalt, petroleum coke, etc. Pipeline transportation is one of the most important modes of transportation for finished oil. Pipeline transportation generally adopts a sequential transportation method to continuously transport multiple batches of different types of oil products to improve transportation efficiency. At present, finished oil is usually transported through long-distance pipelines to ensure the quality of each batch of finished oil. During the transportation of finished oil, it is usually necessary to determine the delivery difference of finished oil (referred to as delivery difference), that is, to determine the difference between the input and output of finished oil. The delivery difference is used to determine the loss of finished oil during the transportation process, and is an important economic indicator for evaluating the delivery task of finished oil.

[0046] In the related art, the corresponding transmission difference is usually determined by the oil volume of the output pipeline, the oil sales volume of the output pipeline and the oil storage volume of the pipeline within a time period. Since the pipeline is long and the oil storage volume of the pipeline is related to multiple parameters such as the physical pipe capacity of the pipeline, the oil product interface, temperature, pressure, density, etc., the technical personnel are unable to accurately determine the oil storage volume of the pipeline within a time period, resulting in the inability to accurately determine the transmission difference, which in turn affects the accuracy of the statistical analysis of the finished oil transportation process data.

[0047] Therefore, there is an urgent need for a method and device for determining the transmission difference of a finished oil pipeline to accurately determine the transmission difference of the finished oil, thereby providing support for the statistical analysis of subsequent finished oil transportation process data.

[0048] In view of this, an embodiment of the present invention provides a method for determining an oil delivery difference in a finished oil pipeline, the method comprising: acquiring oil delivery data, the oil delivery data comprising an input amount, an output amount, and an amount of mixed oil products between any two adjacent batches of oil products in each of a plurality of batches delivered through a target pipeline in a target delivery sequence within a target period, wherein the input amount is the amount of oil products entering the target pipeline, and the output amount is the amount of oil products leaving the target pipeline; determining an oil mixing amount corresponding to the oil products in the target batch according to the amount and density of the mixed oil products between any two adjacent batches, the oil mixing amount being the sum of the oil mixing amounts corresponding to two oil mixing areas before and after the target batch, the target batch being any one of the plurality of batches; determining an oil delivery difference corresponding to the oil products in the target batch according to the input amount, output amount, and oil mixing amount corresponding to the oil products in the target batch.

[0049] The method provided by the embodiment of the present invention obtains oil product delivery data, the oil product delivery data includes the input amount, output amount and the amount of mixed oil products between any two adjacent batches of each batch of oil products in the target period according to the target delivery sequence through the target pipeline; the mixed oil amount corresponding to the target batch of oil products is determined according to the amount and density of the mixed oil products between any two adjacent batches, and the mixed oil amount is the amount of oil products included in the mixed oil products; the oil delivery difference corresponding to the target batch of oil products is determined according to the input amount, output amount and mixed oil amount corresponding to the target batch of oil products. In the related art, the oil delivery difference is usually determined by the oil product input amount, output amount and pipeline inventory amount. Since the technicians cannot accurately determine the pipeline inventory amount of the oil products, the determined oil delivery difference is inaccurate. The method provided by the embodiment of the present invention can improve the accuracy of the finished oil delivery difference and solve the problem of large oil delivery difference error.

[0050] In some embodiments, the method for determining the difference in oil delivery in a finished oil pipeline provided in an embodiment of the present invention may be performed by a device 100 for determining the difference in oil delivery in a finished oil pipeline (hereinafter referred to as the determination device 100). As an example, the determination device 100 may be any electronic device 200 with data processing capabilities, such as a general-purpose computer, a personal computer, a laptop computer, a switch, or a tablet computer, etc. The specific implementation of the purchase list determination device 100 is not limited here.

[0051] Figure 1 The hardware structure diagram of the electronic device provided by the embodiment of the present invention is shown. The electronic device 200 includes a processor 210 , a memory 220 and a communication interface 230 .

[0052] The processor 210 may include one or more processing cores. The processor 210 uses various interfaces and lines to connect various parts in the electronic device 200, and executes various functions and processes data of the electronic device 200 by running or executing instructions, programs, code sets or instruction sets stored in the memory 220, and calling data stored in the memory 220. Optionally, the processor 210 can be implemented in at least one hardware form of a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP), a field-programmable gate array (FPGA), and a programmable logic array (PLA).

[0053] The memory 220 may include a random access memory (RAM) or a read-only memory (ROM). Optionally, the memory 220 includes a non-transitory computer-readable storage medium. The memory 220 may be used to store instructions, programs, codes, code sets, or instruction sets. The memory 220 may include a program storage area.

[0054] The communication interface 230 is used to communicate with other devices, equipment or communication networks, such as data storage devices, image processing equipment or Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.

[0055] In physical implementation, the above-mentioned components (such as processor 210, memory 220 and communication interface 230) can be components in the same device (such as a laptop). Alternatively, at least two of the components can be set in the same device, that is, as different components in one device, such as a deployment method similar to devices or components in a distributed system.

[0057] The following describes a method for determining the oil delivery difference of a refined oil pipeline provided by an embodiment of the present invention in conjunction with the accompanying drawings.

[0058] Figure 2 A flowchart of a method for determining the difference in oil delivery in a finished oil pipeline provided by an embodiment of the present invention. Optionally, the method may be Figure 1 The electronic device 200 shown is executed, that is, the determination device 100 is executed. The method may include the following steps:

[0059] S1. Obtain oil transportation data.

[0060] The oil product delivery data includes the input amount, output amount and the amount of mixed oil products between any two adjacent batches of oil products in each batch of multiple batches delivered through the target pipeline in the target delivery sequence within the target period. The input amount is the amount of oil products entering the target pipeline, and the output amount is the amount of oil products leaving the target pipeline;

[0061] Specifically, the input amount of each batch of oil products is the sum of each batch of oil products injected by multiple injection metering stations connected to the pipeline, and the output amount of each batch of oil products is the sum of each batch of oil products output by multiple distribution metering stations connected to the pipeline.

[0062] For example, see Figure 3 , Figure 3 This is a schematic diagram of oil product transportation shown in an embodiment of the present invention. Five batches of oil products are transported in a target pipeline in a target transportation order, namely batch 1, batch 2, batch 3, batch 4 and batch 5. There is a mixed oil zone between any two adjacent batches of oil products, namely mixed oil zone 1, mixed oil zone 2, mixed oil zone 3 and mixed oil zone 4.

[0063] It should be understood that multiple batches of oil products can be of the same type or different types, for example, gasoline or diesel. When two adjacent batches of oil products are of the same type but different product numbers, the amount of mixed oil between the two adjacent batches of oil products is 0.

[0064] It should be noted that the embodiment of the present invention does not impose any particular limitation on the specific type of oil products, and the oil products may be any type of oil products that need to pass through the target pipeline.

[0065] S2. Determine the mixed oil amount corresponding to the target batch of oil products according to the oil product quantity and density of the mixed oil products between any two adjacent batches. The mixed oil amount is the sum of the mixed oil amounts corresponding to the two mixed oil areas before and after the target batch.

[0066] Specifically, each mixed oil zone includes two different batches of oil products, and the target batch is any one of the multiple batches. For ease of understanding, the following embodiment uses batch 3 as the target batch for explanation. The oil product delivery data includes the input and output of each batch of oil products, and also includes the amount of mixed oil products in each of the four mixed oil zones. Figure 3 When the target batch is batch 3, the mixed oil amount corresponding to the oil products of the target batch is the amount of oil products included in the mixed oil zone 2 and the mixed oil zone 3.

[0067] In one possible implementation, see Figure 4 The above S2 specifically includes the following steps:

[0068] S21, determining a first mixed oil amount and a second mixed oil amount corresponding to the target batch of oil products according to the quantity and density of the mixed oil products between any two adjacent batches.

[0069] Among them, the first mixed oil amount is the mixed oil amount belonging to the target batch between the oil products of the previous batch of the target batch and the oil products of the target batch in the target delivery sequence, and the second mixed oil amount is the mixed oil amount belonging to the target batch between the oil products of the next batch of the target batch and the oil products of the target batch in the target delivery sequence.

[0070] In combination with the above example, when the target batch is batch 3, the first oil mixing amount is the oil mixing amount between the oil products of batch 2 and the oil products of batch 3. That is, the amount of oil products belonging to batch 3 in the oil mixing area 2. The second oil mixing amount is the oil mixing amount between the oil products of batch 4 and the oil products of batch 3. That is, the amount of oil products belonging to batch 3 in the oil mixing area 3.

[0071] S22. Determine the sum of the first mixed oil amount and the second mixed oil amount corresponding to the target batch of oil products as the mixed oil amount corresponding to the target batch of oil products.

[0072] In some embodiments, the formula for determining the first mixed oil amount corresponding to the target batch of oil products is:

[0073] S1=h1*w1;

[0074]

[0075] Wherein, S1 is the first mixed oil amount corresponding to the target batch of oil products, h1 is the amount of mixed oil products between the target batch of oil products and the previous batch of oil products; w1 is the mass fraction of the target batch of oil products in the mixed oil products between the target batch of oil products and the previous batch of oil products; ρ w1 is the density of the mixed oil between the target batch of oil and the previous batch of oil, ρ1 is the density of the target batch of oil, and ρ2 is the density of the previous batch of oil;

[0076] In other embodiments, the formula for determining the second mixed oil amount corresponding to the target batch of oil products is:

[0077] S2=h2*w2;

[0078]

[0079] Wherein, S2 is the second mixed oil amount corresponding to the target batch of oil products, h2 is the amount of mixed oil products between the target batch of oil products and the next batch of oil products; w2 is the mass fraction of the target batch of oil products in the mixed oil products between the target batch of oil products and the next batch of oil products; ρ w2is the density of the mixed oil between the target batch of oil and the subsequent batch of oil, ρ1 is the density of the target batch of oil, and ρ3 is the density of the subsequent batch of oil.

[0080] In combination with the above example, when batch 3 is diesel and batch 2 is gasoline, the formula for determining the first mixed oil amount corresponding to the oil products of batch 3 is:

[0081] S1=h 混 *w1;

[0082]

[0083] Among them, S1 is the first mixed oil amount corresponding to the oil product of batch 3, h 混 is the amount of oil in the mixed oil zone 2 between the oil of batch 3 and the oil of batch 2; w1 is the mass fraction of the oil of batch 2 in the mixed oil zone 2; ρ w1 is the average density of the mixed oil zone 2, ρ1 is the density of the oil from batch 3, and ρ2 is the density of the oil from batch 3.

[0084] S3. Determine the oil delivery difference corresponding to the target batch of oil products according to the input amount, output amount and mixed oil amount corresponding to the target batch of oil products.

[0085] In one possible implementation, see Figure 5 The above S3 specifically includes the following steps:

[0086] S31, determining the sum of the output amount and the mixed oil amount corresponding to the target batch of oil products;

[0087] S32. Determine the difference between the input amount corresponding to the target batch of oil products and the sum of the output amount and the mixed oil amount as the oil delivery difference corresponding to each batch of oil products.

[0088] In a possible implementation, the formula for determining the oil delivery difference corresponding to the target batch of oil products is:

[0089] Δm x =∑mi x -(∑mo x +m hx );

[0090] Among them, Δm x is the oil delivery difference corresponding to the target batch of oil products, ∑mi x is the input amount corresponding to the target batch of oil products, ∑mo x is the output volume of the target batch of oil products; m hx is the mixed oil amount corresponding to the target batch of oil products.

[0091] Furthermore, the method provided in the embodiment of the present invention further includes the following steps:

[0092] Determine the batch error rate corresponding to the target batch of oil products.

[0093] Among them, the batch error rate m x The formula for determining is:

[0094] m x =(Δm x / ∑mi x )*100%;

[0095] Optionally, the method provided in the embodiment of the present invention further includes the following steps:

[0096] S4. Determine the sum of the oil delivery differences corresponding to each batch of oil products in the multiple batches as the oil delivery difference of the oil product corresponding to the target cycle.

[0097] Exemplarily, the oil product delivery data include the input quantity, output quantity and oil quantity of each batch of oil products delivered through the target pipeline in the target delivery order from April 2024 to May 2024, and the oil product quantity of the mixed oil products between any two adjacent batches. The oil delivery difference of each batch of oil products is determined in turn, and the sum of the oil delivery differences of the five batches of oil products is determined as the oil delivery difference of the oil products corresponding to April 2024 - May 2024.

[0098] It should be understood that the target batch is any one of the multiple batches, that is, the method for determining the oil delivery difference corresponding to each batch of oil products is the same as the method for determining the oil delivery difference corresponding to the target batch of oil products, which will not be repeated here.

[0099] As can be seen from S1-S4, the method provided by the embodiment of the present invention obtains oil product delivery data, and the oil product delivery data includes the input amount, output amount, and oil product quantity of mixed oil products between any two adjacent batches of each batch of oil products in multiple batches delivered through the target pipeline in the target delivery order within the target period; the mixed oil amount corresponding to the target batch of oil products is determined according to the oil product quantity and density of the mixed oil products between any two adjacent batches, and the mixed oil amount is the sum of the mixed oil amounts corresponding to the two mixed oil areas before and after the target batch; the oil delivery difference corresponding to the target batch of oil products is determined according to the input amount, output amount, and mixed oil amount corresponding to the target batch of oil products. In the related art, the oil delivery difference is usually determined by the oil product input amount, output amount, and pipeline inventory. Since the technicians cannot accurately determine the pipeline inventory of the oil products, the determined oil delivery difference is inaccurate. The method provided by the embodiment of the present invention can improve the accuracy of the finished oil delivery difference and solve the problem of large oil delivery difference error.
