Technical Field
[0001] This invention relates to the field of control of engineering machinery and equipment, specifically to a method, device, and computer equipment for displacement in fracturing truck operations. Background Technology
[0002] Fracturing trucks are a core piece of equipment in fracturing and production enhancement operations. During these operations, multiple fracturing trucks often work together in a fracturing unit. When multiple fracturing trucks are operating in coordination, it is necessary to calculate the displacement of each truck within the fracturing unit. Summary of the Invention
[0003] In view of this, the present invention provides a displacement allocation method, device and computer equipment for fracturing truck group construction, so as to obtain the displacement of each fracturing truck in the fracturing unit when multiple fracturing trucks work together.
[0004] In a first aspect, the present invention provides a method for displacement allocation in fracturing truck group operations, the method comprising the following steps: obtaining a total instantaneous displacement demand value; obtaining performance parameters of each fracturing truck in the fracturing truck group, wherein the performance parameters include the gear of the fracturing truck, the displacement corresponding to the gear, and the pressure corresponding to the gear; determining the construction fracturing truck and the construction parameters of each construction fracturing truck based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck, wherein the construction parameters include at least one of the following: construction gear and generator speed.
[0005] The displacement allocation method for fracturing truck group construction provided in this embodiment obtains the total instantaneous displacement demand value and the performance parameters of each fracturing truck in the fracturing truck group. Therefore, the construction parameters of the construction fracturing truck and each construction fracturing truck can be determined based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck. Compared with manual calculation, this embodiment can improve the intelligence level of the displacement allocation method in fracturing truck group construction.
[0006] In one optional implementation, determining the fracturing truck and its operational parameters based on the total instantaneous displacement demand and the performance parameters of each fracturing truck includes: selecting fracturing trucks from the fracturing truck group based on the total instantaneous displacement demand and the performance parameters of each fracturing truck; using the selected fracturing trucks to form a fracturing truck group and determining the current actual value of the total instantaneous displacement of the fracturing truck group; obtaining the operational gear of each fracturing truck in the fracturing truck group and the actual value of the total instantaneous displacement of the fracturing truck group when the current actual value of the total instantaneous displacement is greater than or equal to the set instantaneous displacement; obtaining the total instantaneous displacement deviation based on the total instantaneous displacement demand and the actual value of the total instantaneous displacement; obtaining the displacement adjustment value of each fracturing truck in the fracturing truck group when the total instantaneous displacement deviation is greater than a preset adjustment dead zone value; and obtaining the operational parameters of each fracturing truck based on the displacement adjustment value and the operational gear of each fracturing truck.
[0007] This allows us to obtain the construction parameters for each fracturing truck that are highly compatible with the total instantaneous displacement requirement.
[0008] In one optional implementation, the displacement allocation method for fracturing truck group construction further includes: when the instantaneous total displacement deviation is less than or equal to the adjustment dead zone value, the construction gear and engine speed of each fracturing truck in the construction group are used as the construction parameters of each fracturing truck.
[0009] This allows us to obtain the construction parameters for each fracturing truck that are highly compatible with the total instantaneous displacement requirement.
[0010] In one optional implementation, a fracturing truck is selected from the fracturing truck group based on the total instantaneous displacement requirement and the performance parameters of each fracturing truck. The selected fracturing trucks are used to form a fracturing truck group, and the current actual total instantaneous displacement value of the fracturing truck group is determined. This process continues until the current actual total instantaneous displacement value is greater than or equal to the set instantaneous displacement. The process then obtains the operating gear of each fracturing truck in the fracturing truck group and the actual total instantaneous displacement value of the fracturing truck group. This includes: a first fracturing truck selection step: selecting the current fracturing truck from the fracturing truck group; a first gear determination step: determining whether the current fracturing truck meets the preset operating conditions; if it does, incrementing the gear of the current fracturing truck by 1; and a first current actual total instantaneous displacement value determination step: when the current operating gear... When the fracturing truck is not in the fracturing truck group, add the current fracturing truck to the group and obtain the actual instantaneous displacement value of each fracturing truck in the group. Based on the actual instantaneous displacement value of each fracturing truck, obtain the actual current total instantaneous displacement value of the group. First loop step: When the actual current total instantaneous displacement value is less than the set instantaneous displacement, select the next fracturing truck in the fracturing truck group, use it as the current fracturing truck, and execute the first gear determination step, the first current total instantaneous displacement value determination step, and the first loop step. This continues until the actual current total instantaneous displacement value is greater than or equal to the set instantaneous displacement, at which point the operating gear of each fracturing truck in the group and the actual total instantaneous displacement value of the group are obtained.
[0011] This allows for more even wear on each fracturing vehicle in the construction vehicle group.
[0012] In one optional implementation, before selecting the next fracturing truck in the fracturing truck group when the actual value of the current total instantaneous displacement is less than the set instantaneous displacement, the method further includes: calculating the difference between the set instantaneous displacement and the actual value of the current total instantaneous displacement; obtaining the correspondence between the gear, displacement, and maximum pressure capacity of each fracturing truck in the fracturing truck group, and determining the increase in displacement when the gear of each fracturing truck in the fracturing truck group is increased by 1 according to the correspondence between the gear, displacement, and maximum pressure capacity of the fracturing truck group; determining the optimal matching fracturing truck based on the difference and the increase in displacement when the gear of each fracturing truck is increased by 1; when the optimal matching fracturing truck is obtained, the actual value of the current total instantaneous displacement of the fracturing truck group is the actual value of the total instantaneous displacement of the fracturing truck group; when the optimal matching fracturing truck cannot be obtained, selecting the next fracturing truck in the fracturing truck group, using the next fracturing truck as the current fracturing truck, and returning to the step of determining whether the current fracturing truck meets the preset construction conditions.
[0013] This allows the actual total instantaneous displacement of the construction vehicle unit to be equal to the set instantaneous displacement.
[0014] In one optional implementation, a fracturing truck is selected from the fracturing truck group based on the total instantaneous displacement requirement and the performance parameters of each fracturing truck. The selected fracturing trucks are used to form a fracturing truck group, and the current actual total instantaneous displacement of the fracturing truck group is determined. This process continues until the current actual total instantaneous displacement is greater than or equal to the set instantaneous displacement. The resulting information includes: a second fracturing truck selection step: selecting the current fracturing truck from the fracturing truck group; a correspondence acquisition step: acquiring the correspondence between the current fracturing truck's gear, displacement, and maximum pressurization capacity; and a maximum gear determination step: determining the current fracturing truck's maximum gear and maximum instantaneous displacement based on the correspondence between the current fracturing truck's gear, displacement, and maximum pressurization capacity, and the construction process pressure. The second step in determining the actual value of the current total instantaneous displacement is as follows: When the current fracturing truck is not in the fracturing truck group, add the current fracturing truck to the fracturing truck group and obtain the actual value of the instantaneous displacement of each fracturing truck in the fracturing truck group; based on the actual value of the instantaneous displacement of each fracturing truck, obtain the actual value of the current total instantaneous displacement of the fracturing truck group; the second loop step is as follows: When the actual value of the current total instantaneous displacement is less than the set instantaneous displacement, select the next fracturing truck in the fracturing truck group, use the next fracturing truck as the current fracturing truck, and execute the corresponding relationship acquisition step, the maximum gear determination step, the second actual value determination step of the current total instantaneous displacement, and the second loop step; until the actual value of the current total instantaneous displacement is greater than or equal to the set instantaneous displacement, obtain the operating gear of each fracturing truck in the fracturing truck group and the actual value of the total instantaneous displacement of the fracturing truck group.
[0015] This allows the fracturing truck in the construction vehicle group to have high power.
[0016] In one optional implementation, determining the maximum gear and maximum instantaneous displacement of the current fracturing truck based on the construction process pressure and the correspondence between the current gear, displacement, and maximum pressurization capacity includes: a second gear determination step: obtaining the current gear of the current fracturing truck; a construction pressure determination step: determining the construction pressure that the current gear can participate in based on the current gear of the current fracturing truck and the preset correspondence between the current gear and maximum pressurization capacity; a third cycle step: when the construction pressure that the current gear can participate in meets the requirements of the construction process pressure, the displacement corresponding to the current gear is taken as the current displacement of the current fracturing truck; when it does not meet the requirements, the current gear is lowered by one gear as the maximum gear of the current fracturing truck, and the displacement corresponding to the maximum gear is taken as the maximum displacement of the current fracturing truck, and the next fracturing truck is selected from the fracturing truck group. The system first selects the fracturing truck for operation and sets the next fracturing truck as the current one. It then executes the second gear determination step, the operation pressure determination step, and the third cycle step. Next, it obtains the actual load rate of the current fracturing truck. Finally, in the fourth cycle step, if the actual load rate is less than a preset load rate threshold, it determines the next gear and executes the second gear determination step, the operation pressure determination step, the third cycle step, the load rate acquisition step, and the fourth cycle step. If the actual load rate is greater than a preset threshold, it lowers the current gear by one level and sets it as the maximum gear for the current fracturing truck. It then sets the displacement corresponding to the maximum gear as the maximum displacement of the current fracturing truck, selects the next fracturing truck in the fracturing truck group, sets it as the current fracturing truck, and executes the second gear determination step, the operation pressure determination step, the third cycle step, the load rate acquisition step, and the fourth cycle step.
[0017] This allows the fracturing truck in the construction vehicle group to have high power.
[0018] In one optional implementation, the displacement allocation method for fracturing truck group construction further includes: after determining the construction fracturing truck and the construction parameters of each construction fracturing truck based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck, the method further includes: obtaining the actual construction pressure; determining whether the actual construction pressure is greater than a preset pressure threshold, wherein the pressure threshold is determined based on the construction process pressure; when the actual construction pressure is greater than the pressure threshold, adjusting the construction parameters of the construction fracturing truck until the actual construction pressure is less than or equal to the pressure threshold.
[0019] Therefore, when the actual construction pressure increases, the construction parameters of the fracturing truck can be adjusted to ensure that the construction can proceed normally.
[0020] Secondly, embodiments of the present invention provide a displacement allocation device for fracturing truck group operations. The device includes a first acquisition module, a second acquisition module, and a processing module. The first acquisition module is used to acquire the total instantaneous displacement demand value. The second acquisition module is used to acquire the performance parameters of each fracturing truck in the fracturing truck group, wherein the performance parameters include the gear of the fracturing truck, the displacement corresponding to the gear, and the pressure corresponding to the gear. The processing module is used to determine the construction fracturing truck and the construction parameters of each construction fracturing truck based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck, wherein the construction parameters include at least one of the following: construction gear and generator speed.
[0021] Thirdly, embodiments of the present invention provide a computer device, including a memory and a processor, which are interconnected.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0032] Currently, the displacement of each fracturing truck in a fracturing unit needs to be calculated manually, and then the gear of each fracturing truck is manually controlled to meet the displacement requirements of the operation. With the increasing number of fracturing truck brands in fracturing units, and even within the same brand, the configurations of fracturing trucks are not entirely the same, manually calculating the displacement of each fracturing truck in the fracturing unit is labor-intensive and prone to errors.
[0033] Based on this, according to an embodiment of the present invention, a displacement allocation method for fracturing truck operation is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0034] This embodiment provides a displacement allocation method for fracturing truck operations, which can be used with computer equipment. Figure 1 This is a flowchart of the fracturing truck displacement allocation method according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:
[0035] Step S101: Obtain the total instantaneous displacement demand value.
[0036] In this embodiment, the total instantaneous displacement demand value is the instantaneous displacement demand value during fracturing truck operation. Since the fracturing truck group includes multiple fracturing trucks, in order to distinguish it from the displacement of each fracturing truck, the instantaneous displacement demand value of the fracturing truck group is called the total instantaneous displacement demand value.
[0037] Step S102: Obtain the performance parameters of each fracturing truck in the fracturing truck group.
[0038] In this embodiment, the performance parameters of any fracturing truck include the gear of the fracturing truck, the displacement corresponding to each gear, and the pressure corresponding to each gear.
[0039] Step S103: Determine the construction fracturing truck and the construction parameters of each construction fracturing truck based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck.
[0040] The displacement allocation method for fracturing truck group construction provided in this embodiment obtains the total instantaneous displacement demand value and the performance parameters of each fracturing truck in the fracturing truck group. Therefore, the construction parameters of the construction fracturing truck and each construction fracturing truck can be determined based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck. Compared with manual calculation, this embodiment can improve the intelligence level of the displacement allocation method in fracturing truck group construction.
[0041] This embodiment provides a displacement allocation method for fracturing truck operations, which can be used with computer equipment. Figure 2 This is a flowchart of another fracturing truck displacement allocation method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps:
[0042] Step S201: Obtain the total instantaneous displacement demand value. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.
[0043] Step S202: Obtain the performance parameters of each fracturing truck in the fracturing truck group. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.
[0044] In this embodiment, the fracturing truck in the fracturing truck group is a mechanical fracturing truck. The performance parameters of any fracturing truck include the gear of the fracturing truck, the displacement corresponding to each gear, and the maximum pressurization capacity corresponding to each gear.
[0045] Table 1. Correspondence between performance parameters of a certain brand of fracturing truck at rated speed.
[0046]
[0047] As shown in Table 1, the brand's fracturing trucks include three models, each of which has 8 gears, and each gear has a corresponding displacement and maximum pressing capacity, i.e., pressure.
[0048] Step S203: Determine the construction fracturing truck and the construction parameters of each construction fracturing truck based on the total instantaneous displacement demand value and the performance parameters of each fracturing truck.
[0049] Specifically, step S203 includes:
[0050] Step S2031: Select a fracturing truck from the fracturing truck group based on the total instantaneous displacement requirement and the performance parameters of each fracturing truck. Use the selected fracturing trucks to obtain the fracturing truck group and determine the current total instantaneous displacement actual value of the fracturing truck group. Continue until the current total instantaneous displacement actual value is greater than or equal to the set instantaneous displacement, and obtain the operating gear of each fracturing truck in the fracturing truck group and the total instantaneous displacement actual value of the fracturing truck group.
[0051] Specifically, step S2031 includes two methods: equalization mode method and high power mode method.
[0052] Specifically, such as Figure 3 The equilibrium mode method shown includes the following steps:
[0053] Step a1: Select the currently operating fracturing truck in the fracturing truck group.
[0054] Specifically, each fracturing truck in the fracturing truck group has a corresponding number, and you can select the fracturing truck currently in operation from the fracturing truck group according to the number.
[0055] For example, when the current fracturing truck is the third fracturing truck selected in the fracturing truck group, the fracturing truck group includes the third fracturing truck selected this time, as well as the first and second fracturing trucks selected previously.
[0056] Step a2: Determine whether the current fracturing truck meets the preset construction conditions.
[0057] Specifically, determining whether the current fracturing truck meets the preset construction conditions includes: determining whether the current fracturing truck has the necessary construction conditions, and / or determining whether the current fracturing truck can meet the pressure requirements of the construction process.
[0058] Step a3: When the condition is met, increase the gear of the current fracturing truck by 1.
[0059] Step a4: When the current fracturing truck is not in the fracturing truck group, add the current fracturing truck to the fracturing truck group and obtain the actual instantaneous displacement value of each fracturing truck in the fracturing truck group.
[0060] Step a5: Calculate the current total instantaneous displacement of the construction vehicle group based on the actual instantaneous displacement of each construction fracturing vehicle.
[0061] Specifically, the actual instantaneous displacement of each fracturing truck is added together to obtain the current total instantaneous displacement of the fracturing truck group.
[0062] Step a6: When the actual value of the current total instantaneous displacement is less than the set instantaneous displacement, select the next fracturing truck in the fracturing truck group, and use the next fracturing truck as the current fracturing truck, then return to step a2;
[0063] Step a7: When the current total instantaneous displacement is greater than or equal to the set instantaneous displacement, obtain the operating gear of each fracturing truck in the operating vehicle group and the actual value of the total instantaneous displacement of the operating vehicle group.
[0064] Specifically, the actual value of the current total instantaneous displacement of the construction vehicle group is the actual value of the total instantaneous displacement of the construction vehicle group.
[0065] As an optional implementation, before selecting the next fracturing truck in the fracturing truck group, the method further includes: calculating the difference between the set instantaneous displacement and the actual value of the current total instantaneous displacement; obtaining the preset correspondence between the gear, displacement, and maximum pressurization capacity of the fracturing truck group; determining the increase in displacement when the gear of each fracturing truck in the fracturing truck group is increased by 1 according to the correspondence between the gear, displacement, and maximum pressurization capacity of the fracturing truck group; determining the optimal matching fracturing truck based on the difference and the increase in displacement when the gear of each fracturing truck is increased by 1; when the optimal matching fracturing truck can be obtained, proceeding to step a7; when the optimal matching fracturing truck cannot be obtained, selecting the next fracturing truck in the fracturing truck group and using the next fracturing truck as the current fracturing truck, returning to step a2.
[0066] Specifically, determining the optimal matching fracturing truck based on the difference and the increase in displacement when each fracturing truck is shifted to a higher gear includes: when there is a fracturing truck whose increase in displacement when shifted to a higher gear is the same as the difference between the set instantaneous displacement and the actual value of the current total instantaneous displacement, then that fracturing truck is the optimal matching fracturing truck.
[0067] As an optional implementation, after calculating the difference between the set instantaneous displacement and the actual value of the current total instantaneous displacement, the method further includes: determining whether the difference is less than a preset threshold; if it is less, executing the step of obtaining the preset correspondence between the gear, displacement, and maximum pressing capacity of the fracturing truck group. Specifically, the instantaneous displacement is set to the total instantaneous displacement requirement value or the total instantaneous displacement requirement value minus the adjustment dead zone value.
[0068] Therefore, the balancing mode method in step S2031 includes a two-layer loop process. The first layer loop involves sequentially selecting fracturing trucks from the fracturing truck group, with each selected fracturing truck having a working gear. After all the fracturing trucks in the fracturing truck group have been cycled through once according to the first layer loop, the fracturing trucks in the fracturing truck group need to be cycled through again. At this time, the gear of each fracturing truck needs to be increased by one gear based on the previous working gear. The above two layers are cycled until the actual value of the current total instantaneous displacement of the fracturing truck group is greater than or equal to the set instantaneous displacement.
[0069] As an optional implementation, when the current fracturing truck does not meet the construction conditions, the next fracturing truck is selected from the fracturing truck group, and the next fracturing truck is used as the current fracturing truck, and the process returns to step a2.
[0070] Specifically, such as Figure 4 As shown, the high-power mode method includes the following steps:
[0071] Step b1: Select the currently operating fracturing truck from the fracturing truck group. For details, please refer to step a1 above, which will not be repeated here.
[0072] Step b2: Obtain the correspondence between the gear, displacement and maximum pressure capacity of the current fracturing truck;
[0073] In this embodiment, the correspondence between the gear, displacement and maximum pressure capacity of the current fracturing truck is that the current fracturing truck includes the gears, the displacement corresponding to each gear, and the maximum pressure capacity corresponding to each gear.
[0074] Step b3: Based on the construction process pressure and the correspondence between the current fracturing truck's gear, displacement, and maximum pressurization capacity, determine the current fracturing truck's maximum gear and maximum instantaneous displacement.
[0075] Specifically, step b3 includes:
[0076] Step b31: Obtain the current gear of the fracturing truck.
[0077] In this embodiment, when the current fracturing truck is selected in the fracturing truck group, the current gear of the current fracturing truck is gear 1; during the loop of step b3, the current gear changes until the maximum gear allowed for the current fracturing truck is reached.
[0078] Step b32: Determine the operating pressure that the current fracturing truck can participate in based on the current gear of the current fracturing truck and the preset correspondence between the current gear of the current fracturing truck and the maximum pressure capacity.
[0079] For example, as shown in Table 1, the construction pressure corresponding to the first gear of the Model 2 fracturing truck is 123 MPa; the construction pressure corresponding to the second gear of the Model 2 fracturing truck is also 123 MPa.
[0080] Step b33: Determine whether the construction pressure available for the current gear meets the requirements of the construction process pressure.
[0081] For example, assuming the construction process pressure requirement is greater than 50 MPa, all seven levels of Model 2 can meet the construction process pressure requirements.
[0082] Step b34: When the conditions are met, the displacement corresponding to the current gear is taken as the current displacement of the fracturing truck; when the conditions are not met, the current gear is lowered by one gear as the maximum gear of the fracturing truck, the displacement corresponding to the maximum gear is taken as the maximum displacement of the fracturing truck, the next fracturing truck is selected from the fracturing truck group, and the next fracturing truck is taken as the current fracturing truck, and the process returns to step b31.
[0083] In other words, when the pressure of the fracturing truck does not meet the pressure requirements of the construction process, the cycle of step b3 ends. At this time, the current gear is reduced by one gear as the current maximum gear of the fracturing truck, and the displacement corresponding to the maximum gear is taken as the current maximum displacement of the fracturing truck.
[0084] Step b35: Obtain the actual load rate of the current fracturing truck.
[0085] Step b36: Determine whether the actual load rate is less than the preset load rate threshold. If it is less, determine the next gear of the current gear and return to step b31. If it is greater, lower the current gear by one gear as the maximum gear of the current fracturing truck, take the displacement corresponding to the maximum gear as the maximum displacement of the current fracturing truck, select the next fracturing truck in the fracturing truck group, and take the next fracturing truck as the current fracturing truck. Return to the step of obtaining the current gear of the current fracturing truck.
[0086] In this embodiment, the load rate threshold can be determined based on the required load rate, for example, by fluctuating up or down by 10% based on the required load rate.
[0087] In other words, when the actual load rate is greater than the load rate threshold, the loop of step b3 ends. At this time, the current gear is reduced by one gear to become the maximum gear of the current fracturing truck, and the displacement corresponding to the maximum gear is taken as the maximum displacement of the current fracturing truck.
[0088] Step b4: When the current fracturing truck is not in the fracturing truck group, add the current fracturing truck to the fracturing truck group and obtain the actual instantaneous displacement value of each fracturing truck in the fracturing truck group.
[0089] Step b5: Calculate the current total instantaneous displacement of the construction vehicle group based on the actual instantaneous displacement of each construction fracturing vehicle.
[0090] Step b6: When the actual value of the current total instantaneous displacement is less than the set instantaneous displacement, select the next fracturing truck in the fracturing truck group, and use the next fracturing truck as the current fracturing truck, then return to step b2;
[0091] Step b7: When the current total instantaneous displacement is greater than or equal to the set instantaneous displacement, obtain the operating gear of each fracturing truck in the operating vehicle group and the actual value of the total instantaneous displacement of the operating vehicle group.
[0092] Therefore, the high-power mode method in step S2031 also includes two loops. The first loop is to obtain the maximum gear and maximum displacement of the current fracturing truck by cycling through the gears of the same fracturing truck under the limits of load rate threshold and construction process pressure. The second loop is to cycle through the fracturing trucks in the fracturing truck group to obtain the construction truck group, until the actual value of the current total instantaneous displacement of the construction truck group is greater than the selected termination displacement of the fracturing truck.
[0093] As an optional implementation, before step b3, the method further includes: determining whether the current fracturing truck meets the construction conditions; if the current fracturing truck does not meet the construction conditions, selecting the next fracturing truck in the fracturing truck group and using the next fracturing truck as the current fracturing truck, and returning to step b2; if the current fracturing truck meets the construction conditions, executing step b3.
[0094] As an optional implementation, before step b3, the method further includes: determining whether the current fracturing truck can meet the construction process pressure requirements; when the current fracturing truck cannot meet the construction process pressure requirements, selecting the next fracturing truck in the fracturing truck group and using the next fracturing truck as the current fracturing truck, and returning to step b2; when the current fracturing truck can meet the construction process pressure requirements, executing step b3.
[0095] Step S2032: Calculate the total instantaneous displacement deviation based on the total instantaneous displacement demand value and the actual total instantaneous displacement value.
[0096] Specifically, the absolute value of the difference between the total instantaneous displacement demand value and the actual total instantaneous displacement value is the total instantaneous displacement deviation.
[0097] Step S2033: Determine whether the instantaneous total displacement deviation is greater than the preset adjustment dead zone value; if the instantaneous total displacement deviation is greater than the preset adjustment dead zone value, proceed to step S2034; if the instantaneous total displacement deviation is less than or equal to the adjustment dead zone value, proceed to step S2036.
[0098] This is because, such as Figure 5 As shown, mechanical vehicles differ from hydraulic vehicles in that their displacement is not linear and cannot be adjusted linearly. The displacement value for each gear is a range, i.e. Figure 5 The curve in the figure is a broken line, meaning that there is an adjustment dead zone value. As shown above, the termination displacement of the fracturing truck is selected as the total instantaneous displacement demand value or the total instantaneous displacement demand value minus the adjustment dead zone value; therefore, when the total instantaneous displacement demand value is allocated using the above step S2031, there may be a situation where the total instantaneous displacement deviation is greater than the adjustment dead zone value, or there may be a situation where the total instantaneous displacement deviation is less than or equal to the adjustment dead zone value.
[0099] Step S2034: Obtain the displacement adjustment value of each fracturing truck in the construction vehicle group based on the instantaneous displacement total deviation.
[0100] Specifically, obtaining the displacement adjustment value of each fracturing truck in the construction vehicle group based on the instantaneous displacement total deviation includes: obtaining the number of fracturing trucks in the construction vehicle group; and obtaining the displacement adjustment value of each fracturing truck in the construction vehicle group by dividing the instantaneous displacement total deviation by the number of fracturing trucks in the construction vehicle group.
[0101] Step S2035: Obtain the construction parameters of each fracturing truck based on the displacement adjustment value of each fracturing truck and the construction gear of each fracturing truck.
[0102] Specifically, the construction parameters of each fracturing truck are obtained based on the displacement adjustment value and the construction gear of each fracturing truck. This includes: for each fracturing truck, obtaining the preset correspondence between the displacement adjustment value and the rotation speed of the fracturing truck, and determining the rotation speed adjustment value of the fracturing truck based on the correspondence.
[0103] For example, Table 1 shows the performance parameters of a certain brand of fracturing truck at its rated engine speed of 1900 rpm. However, fracturing trucks of different brands and configurations have different performance parameters. Fine-tuning of displacement can be achieved by adjusting engine speed. When the rated engine speed is 1900 rpm, the adjustable engine speed range is 1700-1900 rpm.
[0104] Step S2036: Use the operating gear of each fracturing truck in the operating vehicle group as the operating parameter for each fracturing truck.
[0105] The embodiments of the present invention provide a displacement allocation method in balanced mode and a displacement allocation method in high-power mode, thereby making displacement allocation applicable to different application scenarios.
[0106] This embodiment provides a displacement allocation method for fracturing truck operations, which can be used with computer equipment. Figure 6 This is a flowchart of another fracturing truck displacement allocation method according to an embodiment of the present invention, such as... Figure 6 As shown, the process includes the following steps:
[0107] Step S601: Obtain the total instantaneous displacement demand value. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.
[0108] Step S602: Obtain the performance parameters of each fracturing truck in the fracturing truck group. For details, please refer to [link to relevant documentation]. Figure 1 Step S102 of the illustrated embodiment will not be described again here.
[0109] Furthermore, before obtaining the performance parameters of each fracturing truck in the fracturing truck group, the displacement allocation method for fracturing truck group operations also includes: obtaining a preset designated fracturing truck for operation. Furthermore, obtaining the performance parameters of each fracturing truck in the fracturing truck group includes: obtaining the performance parameters of each fracturing truck in the fracturing truck group other than the designated fracturing truck for operation.
[0110] This is because, to prevent sediment buildup, it is prohibited for the overall displacement of the fracturing truck unit to be zero during operation. If this occurs, sediment buildup is highly likely. Therefore, a designated fracturing truck can be manually assigned; this truck's operation is not affected by the displacement allocation and represents the base displacement of the entire fracturing truck unit. For example... Figure 5 As shown, displacement adjustment is achieved based on the displacement base.
[0111] Step S603: Determine the construction fracturing truck and its construction parameters based on the total instantaneous displacement requirement and the performance parameters of each fracturing truck. For details, please refer to [link to relevant documentation]. Figure 2 Step S203 of the illustrated embodiment will not be described again here.
[0112] Step S604: Obtain the actual construction pressure.
[0113] Step S605: Determine whether the actual construction pressure is greater than the preset pressure threshold, wherein the pressure threshold is determined according to the construction process pressure; if the actual construction pressure is greater than the pressure threshold, proceed to step S506; otherwise, return to step S604.
[0114] Step S606: Adjust the construction parameters of the fracturing truck until the actual construction pressure is less than or equal to the pressure threshold.
[0115] In this embodiment, the gear position of the fracturing truck can be adjusted, as can the rotation speed of the fracturing truck; the operating parameters of only one fracturing truck can be adjusted, or the operating parameters of multiple fracturing trucks can be adjusted.
[0116] As mentioned above, adjusting the construction parameters of the fracturing truck includes: for each fracturing truck, obtaining the preset correspondence between the displacement adjustment value and the rotation speed of the fracturing truck, and determining the rotation speed adjustment value of the fracturing truck based on the correspondence.
[0117] The displacement allocation method of this invention can not only improve the intelligence level of displacement allocation method in fracturing truck operation, but also monitor the actual construction pressure during fracturing truck operation. If the actual construction pressure increases, the construction parameters of the fracturing truck can be adjusted to ensure that the construction can proceed normally.
