Background Technology
[0002] In seismic data acquisition operations for oil exploration, as the density of borehole parameters in the field observation system increases year by year, and the requirements for acquiring higher-precision raw seismic data gradually increase, the amount of geophysical core equipment and labor required on-site has increased exponentially. Therefore, under the requirement of decreasing exploration investment, nodal seismographs, controllable seismic sources, and well-shot source drive systems are used in related technologies to reduce labor and improve production efficiency. However, at least the following problems exist in the current seismic acquisition construction: taking nodal seismographs as an example, because their working status is not visible and production data information cannot be transmitted in real time, some nodal seismographs, even if they have completed their work and are idle, must wait for all nodal seismographs to complete their work before being moved to acquire data from the next area. That is, all nodal equipment in the same operation can only complete one preset acquisition.
[0003] Therefore, there is an urgent need for a method to determine the remaining shot pairs in order to solve the problem of low resource utilization and production efficiency caused by the invisibility of the status of nodal seismometers during construction operations. Summary of the Invention

[0009] As an optional implementation, determining the remaining shot pairs of the geophone based on the shot logarithmic value of the geophone and the information on the fired shot points within the acquisition construction template range obtained during construction includes: determining the fired shot points that correspond to the geophone based on the information on the fired shot points within the acquisition construction template range obtained during construction; and calculating the remaining shot pairs of the geophone for each geophone within the construction template range using the following formula.
[0010] Ds = Dz - Sn;
[0011] Wherein, Ds is the remaining shot pairs of the geophone, Dz is the total shot pairs of the geophone within the construction template range, and Sn is the number of shot points that have been excited among the shot points that correspond to the geophone.
[0012] As an optional implementation, the method further includes determining the range of blasting pairs within the scope of the construction template, including calculating the range of blasting pairs within the scope of the construction template using the following formula:
[0013] Dz≥Dmin=S;
[0014] Dz≤Dmax=L*S*T*ΔX / SLI;
[0015] Wherein, Dz is the total number of blasting pairs within the construction template range, Dmin is the minimum total number of blasting pairs, Dmax is the maximum total number of blasting pairs, S is the number of blasts in the template, L is the number of receiving lines in the template, T is the number of receiving channels per receiving line in the template, ΔX is the channel spacing, and SLI is the firing line spacing.
[0016] Secondly, this application provides a method for determining the idle status of geophysical equipment, comprising: determining the geophysical point as an idle geophysical point when the remaining logarithmic value of the geophysical point within the acquisition construction template is determined to be 0 according to the above-mentioned remaining logarithmic pair determination method; and determining the geophysical equipment at the idle geophysical point as being in an idle state.
[0017] Thirdly, this application provides a method for displaying the occupancy of geophysical equipment, comprising: determining, according to the above-mentioned method for determining the remaining shot pairs, the proportion of the remaining shot pairs of each geophone point within the acquisition construction template to the total shot pairs of the geophone point; wherein, the proportion is used to characterize the occupancy status of the geophysical equipment; and when the proportion falls into different preset ratio ranges, the geophone point is displayed in different colors in the visualization interface.
[0018] Fourthly, this application provides an electronic device, including a processor, a communication interface, a memory, and a communication bus, wherein the processor, the communication interface, and the memory communicate with each other through the communication bus; the memory is used to store computer programs; the processor is used to execute the aforementioned remaining blast track pair determination method, geophysical equipment idle determination method, or geophysical equipment occupancy display method stored in the memory.
[0019] Fifthly, this application provides a method for rolling operation of geophysical equipment, comprising: for a geophone point within the acquisition construction template, using the remaining shot pair determination method, if the remaining shot pair value of the geophone point is determined to be lower than a preset value, the geophysical equipment at the geophone point is determined as a relocation object, to be moved to another preset receiving point for the next seismic wave acquisition; after determining the relocation object to be moved to an idle state using the geophysical equipment idle determination method, the geophysical equipment is moved for rolling operation.
[0020] The technical solutions provided in this application have the following advantages compared with the prior art:
[0021] The remaining shot pairs determination method provided in this application utilizes the correspondence between different shot receivers in the seismic acquisition template to calculate all shot pairs within the acquisition template. Combined with real-time updated shot point excitation progress information, it quickly calculates the number of remaining shot pairs for each receiver, providing data support and decision guidance for real-time production command and template rolling and burial, thereby enabling timely and effective production command and burial operations, and significantly improving the efficiency of seismic acquisition production operations.
[0022] Furthermore, this method for determining remaining shot pairs provides a rolling operation method for geophysical equipment. In actual production, compared to the traditional method of centralized relocation after all equipment has completed its work, this method leverages the ease of relocation and burial of node equipment. It allows receivers that have completed their work within the template to be prepared for relocation and burial without waiting for other points to complete their work. This enables construction personnel to arrive in advance at the burial area of receivers with lower remaining shot pair values. Once the remaining shot pair value becomes 0, the equipment is promptly relocated and transported to the pre-set location in the next acquisition phase, preparing it for secondary acquisition in subsequent periods. This achieves rapid transfer and burial to different design locations, allowing the same equipment to receive data two or more times in a shorter time, significantly improving the rolling acquisition efficiency, increasing overall rolling acquisition efficiency, reducing equipment idle time, and improving daily acquisition efficiency. It also fully utilizes the clustering and lightweight, high-efficiency advantages of the equipment, achieving significant improvements in resource input and production efficiency compared to traditional methods. This maximizes equipment and resource utilization, increases daily production efficiency, and reduces production costs.
[0023] Furthermore, applying this method for determining remaining shot pairs, this application embodiment also provides a method for determining the vacancy status of geophysical equipment and a method for displaying the occupancy status of geophysical equipment. Based on the method for determining remaining shot pairs, the vacancy status of geophysical equipment is further determined in real time and the occupancy status of geophysical equipment is displayed. The determination method eliminates the possibility of errors in manual calculation leading to misplacement of equipment on site. Moreover, the vacancy determination method and occupancy display method better assist construction organization decision-making, and effectively solve the problem of the invisible status of nodal seismographs during construction operations. It makes full use of information technology to innovate production operation mode, and ultimately achieves the goal of real-time acquisition, real-time command and dispatch, and real-time rolling operation, which greatly improves resource utilization and production efficiency, and to a large extent realizes cost reduction and efficiency improvement in seismic acquisition operations without increasing resource input.
[0024] Furthermore, the method provided in this application embodiment consumes very few computing resources, with a computational response time as low as milliseconds. It solves the problem that traditional traversal algorithms consume too many computing resources for dynamic big data of construction, and take too long to achieve real-time analysis and calculation to provide accurate results. It is more convenient to promote and apply in field front-line work teams. It is simple, efficient, easy to use in production, and highly practical, with broad application prospects.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0034] Figure 1 This is a flowchart illustrating a method for determining the remaining artillery pairs according to an embodiment of this application.
[0035] like Figure 1 As shown in the figure, this application provides a method for determining remaining shot pairs, which includes the following steps:
[0036] In S1, based on the work area data and the collected construction plan, the shot point data of all shot points to be excited in the plan, the geophone point data of all geophone points in the plan, and the shot-geophone point relationship data are determined.
[0037] Specifically, the work area data can include three-dimensional work area information, including observation system parameters, design physical point measurement network and parameters, and data acquisition and construction plans.
[0038] Shot point data, i.e., firing point data, can include the shot point's line number, station number, coordinates, etc. Receiver point data, i.e., node data, can include the receiver point's line number, station number, coordinates, etc. Relationship data can include the correspondence between shot and receiver points, such as which receiver points correspond to each shot point, which nodes are needed to acquire data from that shot point, and which shot points correspond to each receiver point.
[0039] Specifically, the shot-receiver relationship data records which receivers collected the excitation at each shot point. Combined with... Figure 3 As shown in the figure, in one possible embodiment, the correspondence of the remaining shot pairs in the method for determining the remaining shot pairs according to another embodiment of this application is as shown in the figure. For example, the first segment arrangement corresponds to the first column of shot points, the second segment arrangement corresponds to the first column of shot points and the second column of shot points, the third segment arrangement corresponds to the first column of shot points and the third column of shot points, and the fourth segment arrangement corresponds to the first column of shot points, the second column of shot points, the third column of shot points and the fourth column of shot points. That is, the detector points in the first segment arrangement are used to collect the excitation of the first column of shot points, the detector points in the second segment arrangement are used to collect the excitation of the first column of shot points and the second column of shot points, the detector points in the third segment arrangement are used to collect the excitation of the first column of shot points and the third column of shot points, and the detector points in the fourth segment arrangement are used to collect the excitation of the first column of shot points, the second column of shot points, the third column of shot points and the fourth column of shot points.
[0040] In one possible embodiment, a pre-shot SPS file is created based on the parameters of the work area observation system and the designed physical points, combined with the acquisition and construction plan. This SPS file includes a shot point data file, a receiver point data file, and a relational data file. The shot point data file contains shot point data, the receiver point data file contains receiver point data, and the relational data file contains relational data.
[0041] Specifically, the acquisition template can be predetermined based on the number of devices. In actual application scenarios, the actual number of acquisition devices usually cannot cover all the detectors in the entire acquisition construction plan. Therefore, the range of the acquisition template is usually smaller than the area covered by the construction plan.
[0042] In S2, based on the shot point data, the receiver point data, and the shot-receiver relationship data, the logarithmic value of the receiver point that falls within the preset acquisition construction template range is determined.
[0043] Specifically, a shot pair is the number of mapping relationships between a certain receiver point in the acquisition construction template and the shot points within the acquisition construction template range. For a receiver point, its shot pair is all the shot points that the receiver point needs to receive within the acquisition construction template range, that is, the total number of shot points corresponding to the receiver point. It can also be understood as the number of mappings. The correspondence between the receiver point and each shot point can be regarded as a mapping.
[0044] Combination Figure 4 As shown in the figure, in one possible embodiment, the acquisition construction template in the method for determining the remaining shot pairs according to another embodiment of this application is illustrated. The blue lines represent the receiver points that need to be deployed throughout the project. Since in actual scenarios, there are usually not enough devices to cover the entire project, the green dots represent receiver points within the acquisition construction template area, which are the actual deployed nodes. The area formed by the green nodes constitutes the acquisition construction template area. The purple dots represent shot points within the template area, and the red dots represent the designed shot points (excitation points) for the entire project. All shot points within the acquisition construction template area must complete one excitation. As the shot points within the acquisition construction template area are excited and the receiver points are acquired, the number of shot pairs at the receiver points gradually decreases. When it decreases to 0, it indicates that the receiver point has completed all its tasks and can be prepared for relocation for secondary acquisition at other locations. The aforementioned receiver point, shot point information, and acquisition construction template information can all be included in the acquisition construction plan.
[0045] It should be noted that, Figure 3 and Figure 4 The shot points and geophones shown are only one possible scenario. For example, in actual uninhabited areas, shot points and geophones can be evenly distributed. In other possible scenarios, such as when the work area includes areas that cannot be set up, such as residential areas that need to be avoided, shot points and geophones are set according to actual coordinates.
[0046] In one possible implementation, the above operation may include: according to the shot point data and the receiver point data, arranging the shot points and receiver points within the acquisition construction template range at the positions corresponding to the acquisition construction template according to coordinates; parsing the shot-receiver point relationship data, extracting the correspondence between each receiver point and shot point within the acquisition construction template range; and determining the number of shot points corresponding to each receiver point as the shot trajectory logarithm of the receiver point.
[0047] Specifically, parsing the shot-detector relationship data and extracting the correspondence between each geophone and shot point within the scope of the acquisition construction template can be implemented by parsing the line number and station number of each geophone used to receive the seismic waves excited by each shot point from the shot-detector relationship data; and determining the correspondence between all geophones and all shot points based on the line number and station number of each shot point contained in the shot point data and the line number and station number of each geophone.
[0048] Combination Figure 3 As shown, for example, based on the shot point data and receiver point data in the scheme, they are arranged at the positions corresponding to the acquisition construction template according to coordinates. The receiver points and shot points shown in the figure are obtained after the above operations. Let Dz represent the total number of shot channels for the receiver points. After the analysis operation, the shot channel pair value of the receiver points is determined. Thus, it can be seen that the first segment arrangement corresponds to the first column of shot points, and the shot channel pair value Dz = 6; the second segment arrangement corresponds to the first column of shot points and the second column of shot points, and the shot channel pair value Dz = 12; the third segment arrangement corresponds to the first column of shot points and the third column of shot points, and the shot channel pair value Dz = 12; the fourth segment arrangement corresponds to the first column of shot points, the second column of shot points, the third column of shot points, and the fourth column of shot points, and the shot channel pair value Dz = 24. The shot channel pair values of subsequent receiver points are also deduced in the same way.
[0049] In one example, extracting the X file (shot-receiver relationship file) from the SPS file reveals all the corresponding shot-receiver relationships. By integrating and organizing the data, the receiver line numbers and receiver point numbers corresponding to each shot are shown in Table 1, which illustrates a portion of the extracted shot-receiver relationship data. The table shows that shot point S83171057 requires 32 receiver lines, with line numbers ranging from R1015 to R1232. Each receiver line has a point number between 2580 and 2885 (306 channels). Therefore, the detailed station numbers of the 9792 (32*306) receiver points corresponding to shot point S83171057 can be obtained.
[0050] Taking a single shot point firing (shot point S8317, line number 1057) as an example, the geophones shown in the table include those starting at station R1015 from station 2580 to station 2885 (ending at station R1232). These 9792 geophones correspond to one shot S83171057. These geophones can be assigned a value (Dz). During the process of parsing the shot-geophone relationship data and extracting the correspondence between each geophone and shot point within the construction template area, a value (Dz = 1) is obtained for all geophones corresponding to shot point S83171057. The correspondence between all shot-geophones is extracted from the X file. For each shot corresponding to a geophone, the shot-track pair is incremented by 1 (Dz = Dz + 1). After extracting and assigning values to all correspondences in the X file, the number of shot points corresponding to each geophone can be intuitively seen through the value (Dz) of the shot-track pair. Figure 3The number of Dz is shown. Therefore, by parsing all the relational data, the shot logarithm value for each can be determined, that is, the number of shot points corresponding to each receiver point.
[0051] Table 1
[0052]
[0053]
[0054] In S3, the remaining shot pairs of the geophone are determined based on the shot pair values of the geophone and the information of the shot points that have been excited within the range of the acquisition construction template obtained during the construction process.
[0055] Specifically, it may include determining the shot points that have been activated among the shot points that correspond to the geophone points based on the shot point information that has been activated within the range of the construction template obtained during the construction process.
[0056] In actual construction, among all the shot points corresponding to a geophone point within the construction template range, whenever a shot point is excited, according to the shot-geophone relationship, the equipment at that geophone point receives a seismic wave excited by that shot point. After this excitation, the logarithmic value of the shot trajectory at that geophone point is reduced by 1.
[0057] The following formula (1) can be derived from the collection of construction templates:
[0058] Ds=Dz-Sn (1)
[0059] In formula (1), Ds represents the remaining shot pairs, Dz represents the total number of shot pairs (i.e., the total number of mappings), and Sn represents the real-time fired shots with mapping relationships. When Ds = 0, it means that a certain receiver point in the arrangement has been used up, and the relevant instruments and equipment can be removed.
[0060] In one possible embodiment, taking a single shot point excitation (shot point S8317 line number 1057) as an example, and referring to Table 1, after the initial assignment of shot-receiver points is completed, i.e., after determining the total number of shot pairs for each receiver point, the number of shot pairs for the receiver points within the range corresponding to each shot is reduced by one, based on the actual progress of field production. For example, if S83171057 has been acquired, the number of shot pairs for the 9792 receiver points R10152580-R12322885 corresponding to it is reduced by 1 (Ds = Dz - 1). As the construction process progresses, the number of remaining shot pairs for the receiver points within the construction template gradually decreases. If the remaining shot pairs of the geophones within the construction template are 0, meaning that all shot points within the template have been excited, the geophones within the construction template need to be moved to the preset position of the geophones for the next round. This is used to calculate the remaining shot pairs for the next round in the shot point area of the next round of excitation. In other words, the remaining shot pairs of the geophones within the construction template are calculated again after the geophones are moved.
[0061] The range of the blasting track within the construction template area can be calculated using the following method:
[0062] When the three-dimensional observation system is a general linear orthogonal observation system, the range of Dz is:
[0063] Dz≥Dmin=S (2)
[0064] Dz≤Dmax=L*S*T*ΔX / SLI (3)
[0065] In formulas (2) and (3), Dmin is the minimum total shot pair, Dmax is the maximum total shot pair, S represents the number of shots in the template of the three-dimensional observation system, L represents the number of receiving lines in the template of the three-dimensional observation system, T represents the number of receiving channels per receiving line in the template of the three-dimensional observation system, ΔX = channel spacing, which can represent the distance between nodes, SLI = excitation line spacing, which can represent the distance between shot point rows.
[0066] Based on the above embodiments, the remaining shot pairs determination method provided in this application utilizes the correspondence between different shot receivers in the seismic acquisition template to calculate all shot pairs within the acquisition template. Combined with real-time updated shot point excitation progress information, it quickly calculates the number of remaining shot pairs for each receiver, providing data support and decision guidance for real-time production command and template rolling and burial, thereby enabling timely and effective production command and burial operations, and significantly improving the efficiency of seismic acquisition production operations.
[0067] Furthermore, the method for determining the remaining shot pairs can further determine the idle status of geophysical equipment in real time and display the occupancy status of geophysical equipment. The determination method also eliminates the possibility of errors in manual calculations that could lead to misplacement of equipment on site. Moreover, the idle determination method and occupancy display method better assist construction organization decisions and effectively solve the problem of the invisible status of nodal seismographs during construction operations. By making full use of information technology to innovate production operation mode, the goal of achieving real-time acquisition, real-time command and dispatch, and real-time rolling operation can be achieved, which can greatly improve resource utilization and production efficiency, and to a large extent realize cost reduction and efficiency improvement in seismic acquisition operations without increasing resource input. Furthermore, it can also be used for the rolling operation of geophysical equipment. In actual production, compared with the traditional method of relocating all equipment after all operations are completed, the easy relocation and burial of node equipment allows the geophones that have completed their operations within the template to be prepared for relocation and burial without waiting for other points to complete their operations. This allows construction personnel to be positioned in advance in the area where geophones with low remaining shot pair values are buried. Once the remaining shot pair values become 0, the relocation and burial operation can be carried out in a timely manner, and the equipment can be transported to the preset position of the next acquisition operation plan. This prepares the equipment for secondary acquisition in subsequent periods, realizing rapid transfer and burial to different design positions. The same equipment can achieve two or more data receptions in a shorter time, greatly improving the rolling acquisition efficiency, increasing the overall rolling acquisition efficiency, reducing equipment idle rate, and increasing daily acquisition efficiency. It also fully leverages the clustering and lightweight, high-efficiency advantages of the equipment, achieving a significant improvement in resource input and production efficiency compared with traditional operations, maximizing equipment and resource utilization, increasing daily production efficiency, and reducing production costs.
[0068] Furthermore, the method provided in this application embodiment consumes very few computing resources, with a computational response time as low as milliseconds. It solves the problem that traditional traversal algorithms consume too many computing resources for dynamic big data of construction, and take too long to achieve real-time analysis and calculation to provide accurate results. It is more convenient to promote and apply in field front-line work teams. It is simple, efficient, easy to use in production, and highly practical, with broad application prospects.
[0069] In one possible embodiment, this application provides a method for determining the idle status of geophysical equipment, comprising: determining the geophysical point as an idle geophysical point when the remaining logarithmic value of the geophysical point within the acquisition construction template is determined to be 0 according to the above-described remaining logarithmic pair determination method; and determining the geophysical equipment at the idle geophysical point as being in an idle state.
[0070] Specifically, geophysical exploration equipment can include a variety of devices, such as special vehicles, receiving instruments, excitation instruments, seismic receiving instruments, etc.
[0071] In one possible embodiment, this application provides a method for displaying the occupancy of geophysical equipment, comprising: determining, according to the above-described method for determining remaining shot pairs, the proportion of the remaining shot pairs of each geophone within the acquisition construction template to the total shot pairs of the geophone; wherein, the proportion is used to characterize the occupancy status of the geophysical equipment; and when the proportion falls within different preset ratio ranges, displaying the geophone in different colors in the visualization interface.
[0072] Combination Figure 5 As shown, Figure 5 This is a schematic diagram illustrating the effect of a geophysical equipment occupancy display method according to another embodiment of this application. Multiple rows, each in a different color, represent all geophones in the acquisition scheme. The points in the middle, displayed in red and gray, represent all shot points. In this embodiment, the proportion of the remaining shot pairs of each geophone to its total shot pairs, obtained by the aforementioned remaining shot pair determination method, can be displayed in different colors. For example, the geophones are gradient-colored according to the percentage reduction in remaining shot pairs. Initially, the geophones are blue; when the remaining shot pairs (Ds) are 0, they are orange. The gradient coloring from blue to orange is applied based on the proportion of remaining shot pairs to the total shot pairs being 75%, 50%, 25%, and 0%. Orange indicates a geophone with 0 remaining shot pairs, meaning that all shot points mapped to this geophone have been acquired. This geophone is idle in the current acquisition scheme, and the geophone is determined to be an idle geophone. The geophysical equipment at this idle geophone is determined to be in an idle state. The "idle state" refers to a location where there is no longer a corresponding mapping relationship with the target shot point, resulting in a shot pair value of 0. Therefore, in practical engineering, construction personnel can be arranged to arrive in advance at the area where the remaining shot pair values are low, and once the remaining shot pair values become 0, the equipment can be moved and buried promptly to the preset location in the next acquisition plan, thus preparing the equipment for secondary acquisition in subsequent periods.
[0073] It should be noted that the above-mentioned methods for displaying the occupancy of geophysical equipment include, but are not limited to, using different colors to represent different occupancy statuses, or any other display method. These methods are sufficient to clearly distinguish the detectors with different proportions of remaining shot pairs to the total shot pairs. This allows for intuitive and accurate calculation and display of the occupancy and idle status of core geophysical equipment resources based on the actual field acquisition progress, enabling real-time production command of dynamic production.
[0074] The aforementioned ratio is used to characterize the occupancy status of geophysical equipment. When the ratio falls within different preset ratio ranges, the detector points are displayed in different colors on the visualization interface. This can be implemented by coloring the remaining shot pairs on the platform's front-end display interface. Similarly, the firing status of shot points can also be displayed using different colors. For example, in the figure, gray shot points represent shot points that have already been fired, and red shot points represent shot points that are yet to be fired.
[0075] Based on the above embodiments, the remaining shot pair determination method according to the embodiments of this application, the geophysical equipment idle determination method and the geophysical equipment occupancy display method provided in the embodiments of this application, further determine the idle status of geophysical equipment in real time and display the occupancy status of geophysical equipment based on the remaining shot pair determination method. The determination method calculation also eliminates the situation of misplacement of on-site arrangement due to errors in manual calculation. Moreover, the idle determination method and occupancy display method better assist construction organization decision-making, and effectively solve the problem of the invisible status of nodal seismographs during construction operations. It makes full use of information technology to innovate production operation mode, and ultimately achieves the purpose of real-time acquisition, real-time command and dispatch, and real-time rolling operation, which greatly improves resource utilization and production efficiency, and to a large extent realizes cost reduction and efficiency improvement of seismic acquisition operations without increasing resource input.
[0076] Furthermore, the method provided in this application embodiment consumes very few computing resources, with a computational response time as low as milliseconds. It solves the problem that traditional traversal algorithms consume too many computing resources for dynamic big data of construction, and take too long to achieve real-time analysis and calculation to provide accurate results. It is more convenient to promote and apply in field front-line work teams. It is simple, efficient, easy to use in production, and highly practical, with broad application prospects.
[0077] In one possible embodiment, combining Figure 6 The method for determining remaining shot pairs according to the embodiments of this application can be applied to the implementation process shown in the figure. For example, the method is applied to a software platform, which receives the input SPS file and generates shot information, executes the steps in the method of the above embodiments, calculates the remaining shot pairs, and also displays the shot detectors and firing status through the front end. As actual production progresses, it outputs and displays the detectors with 0 remaining shot pairs, and displays the distribution of the remaining shot pairs, including the above-described embodiment of the geophysical equipment occupancy display method, thereby serving construction organization decisions.
[0078] Based on the same inventive concept, more details and beneficial effects of this embodiment can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.
[0079] In one possible instance, combining Figure 2 , Figure 2This is a flowchart illustrating a method for rolling operation of geophysical equipment according to an embodiment of this application. The method includes: for a geophone point within the acquisition template, using the remaining shot pair determination method, if the remaining shot pair value of the geophone point is determined to be lower than a preset value, the geophysical equipment at the geophone point is identified as a relocation object, to be moved to another preset receiving point for the next seismic wave acquisition; after determining the relocation object to be relocated to an idle state using the geophysical equipment idleness determination method, the geophysical equipment is moved for rolling operation. The rolling operation method for geophysical equipment, applied in this embodiment, realizes an optimized layout method for three-dimensional seismic acquisition templates. This embodiment may include the following steps:
[0080] Step 1: Collect 3D work area data, including observation system parameters, design of physical point measurement network and parameters, and acquisition of construction plans, etc.
[0081] Step 2: Based on the parameters of the work area observation system and the designed physical points, and in conjunction with the data acquisition and construction plan, create a pre-blast SPS file, including:
[0082] (1) The shot point data file contains data such as the line number, station number, and coordinates of the shot points;
[0083] (2) The receiver point data file contains data such as the line number, station number, and coordinates of the receiver point;
[0084] (3) The relational data file contains the corresponding relationship between the gun and the gun receiver.
[0085] Step 3: Parse the X file and assign initial values to each detector point.
[0086] Step 4: Based on the actual progress of field production, for each shot collected, the shot path pairs of the receiver points within the range corresponding to the shot point are reduced by 1.
[0087] Step 5: When the remaining shot pairs of the receiver point are 0, it means that all the shot points mapped by this receiver point have been acquired.
[0088] Step 6: Construction personnel should arrive in advance at the geophone burial area where the remaining blast channel values are low and wait for the remaining blast channel values to become 0 before carrying out the burial operation.
[0089] Based on the above embodiments, in actual production, compared with the traditional construction method of centralized relocation after all equipment has completed its work, the easy relocation and burial of node equipment allows the detection points that have completed their work within the template to be prepared for relocation and burial without waiting for other points to complete their work. This allows construction personnel to arrive in advance at the burial area of detection points with lower remaining shot pair values. Once the remaining shot pair values become 0, the relocation and burial work can be carried out in a timely manner, and the equipment can be transported to the preset location of the next acquisition construction plan. This prepares the equipment for secondary acquisition in subsequent periods, realizing rapid transfer and burial to different design locations. The same equipment can achieve two or even more data receptions in a shorter time, greatly improving the acquisition rolling efficiency, improving the overall acquisition rolling efficiency, reducing equipment idle rate, and increasing the daily acquisition efficiency. It also fully leverages the clustering and lightweight, high-efficiency advantages of the equipment, achieving a significant improvement in resource input and production efficiency compared with traditional operations, maximizing equipment and resource utilization, increasing daily production efficiency, and reducing production costs.
