Description

Technical Field

[0001] This invention relates to the field of geophysical exploration technology, and in particular to a method, device, equipment, and medium for controlling the vibration of a source group. Background Technology

[0002] Currently, in onshore oil seismic exploration, seismic data is acquired by controlling the vibration of the source group. Specifically, the source group transmits data to the control center via a source radio station, and the control center receives the source group data via a central radio station. The control center then sends control commands to the source group via a central radio station; the source group receives these commands via its source radio station; and the source group vibrates according to the control commands to acquire seismic data. Summary of the Invention

[0003] During the acquisition of seismic data in the field, due to the influence of the terrain, there are areas that the control center's central radio signal cannot cover (also called shadow areas). When the source group is in a shadow area, it sends data to the control center via its source radio. The control center cannot receive the source group's data via its central radio; without receiving the source group's data, the control center cannot generate control commands; furthermore, the control center cannot send the control commands to the source group via its central radio; thus, the source group cannot generate seismic data according to the control commands, and the acquisition of seismic data cannot be achieved.

[0004] In view of the above problems, the present invention is proposed to provide a method, apparatus, medium, or device for controlling the vibration of a source group to overcome or at least partially solve the above problems.

[0005] This invention provides a method for controlling the vibration of a group of seismic sources, comprising:

[0006] Plan the driving route of the seismic source group based on topographic data and source group identification;

[0007] Based on the location information of the control center and the driving route, determine the coverage status of the central radio signal at the path points in the driving route;

[0008] The radio signal coverage status of the driving path and path points is sent to the seismic source group through the central communication component, which includes a central radio station and a central satellite component; so that the seismic source group can determine the radio signal coverage status of the seismic source group based on the location information of the seismic source group, the driving path and the radio signal coverage status of the path points.

[0009] The source group data sent by the source group is received through the central communication component corresponding to the source group communication component that sends source group data.

[0010] Control commands are generated based on the source group data and time-distance rules;

[0011] The radio signal coverage status of the seismic source group is determined, and control commands are sent to the seismic source group through the central communication component selected based on the radio signal coverage status, so that the seismic source group can control the vibration status according to the control commands.

[0012] A further optional implementation involves planning the travel path of the seismic source group based on terrain data and source group identifiers, including:

[0013] Several driving routes are determined based on the highest point, lowest point, maximum elevation difference, slope, and coordinates of the terrain. The driving routes of the seismic source group are then planned based on the aforementioned driving routes and the seismic source group identifiers.

[0014] A further optional implementation involves determining the central radio signal coverage status of path points along the travel path based on the location information of the control center and the travel path, including:

[0015] Based on the location information of the control center and the driving path, determine the slope of the path points in the driving path when they are in front of the control center;

[0016] Compare the slope with the slope threshold;

[0017] If the slope is less than the slope threshold, the central radio station signal of the path point will cover it;

[0018] If the slope is not less than the slope threshold, the radio signal at the center of the path point will not be covered.

[0019] A further optional implementation involves determining the radio signal coverage status of the seismic source group, including:

[0020] Based on the time of receiving the source group data, the time of generating the control command, the source group velocity in the source group data, and the travel path of the source group, determine the path point of the source group on the travel path at the time of generating the control command.

[0021] The radio signal coverage status of the earthquake source group is determined based on the central radio signal coverage status at the path points of the travel path.

[0022] A further optional implementation includes, when receiving source group data:

[0023] The time difference is determined based on the time when the data from the source group is received and the time when the travel path is sent to the source group.

[0024] Compare the time difference with the preset time difference;

[0025] If the time difference exceeds the preset time difference, the travel path of the source group and the coverage status of the central radio signals at the path points in the travel path are re-determined and sent to the source group through the central communication component, and the received source group data is discarded.

[0026] If the time difference is not greater than the preset time difference, the received source group data will be retained.

[0027] A further optional implementation, after sending control commands to the source group, also includes:

[0028] Based on the location of the seismic source group in the data, the travel path of the seismic source group and the coverage status of the central radio signals at the path points are re-determined and sent to the seismic source group through the central communication component.

[0029] This invention provides a method for controlling the vibration of a group of seismic sources, comprising:

[0030] The source communication component receives the travel path of the source group and the coverage status of the central radio signals at the path points sent by the control center through the source communication component. The source group communication component includes a source radio and a source satellite component.

[0031] At a specified time interval, the radio signal coverage status of the seismic source group is determined based on the location information of the seismic source group and the central radio signal coverage status of the path point; and the seismic source group data is sent to the control center through the seismic source communication component selected according to the radio signal coverage status.

[0032] The source communication component receives control commands through the central communication component that sends control commands to the control center; and controls the vibration state according to the control commands.

[0033] A further optional implementation involves determining the radio signal coverage status of the seismic source group based on its location information and the central radio signal coverage status of the path points, and then transmitting the seismic source group data to the control center via a seismic source communication component selected based on the radio signal coverage status, including:

[0034] Based on the location information and travel path of the seismic source group, the path points where the seismic source group is located are determined;

[0035] If the central radio signal of the path point covers the area, then the central radio signal of the source group will also cover the area; select the source radio station based on the coverage of the central radio signal of the source group and send the source group data to the control center;

[0036] If the central radio signal of the path point is not covered, then the central radio signal of the source group is not covered; based on the situation where the central radio signal of the source group is not covered, the source satellite component is selected and the source group data is sent to the control center.

[0037] This invention provides a control device, comprising:

[0038] The driving path determination module is used to plan the driving path of the seismic source group based on terrain data and seismic source group identification.

[0039] The signal status determination module is used to determine the signal coverage status of the central radio station at the path point in the driving path based on the location information of the control center and the driving path.

[0040] The path transmission module is used to send the radio signal coverage status of the driving path and path points to the seismic source group through the central communication component, which includes a central radio station and a central satellite component; so that the seismic source group can determine the radio signal coverage status of the seismic source group based on the location information of the seismic source group, the driving path and the radio signal coverage status of the path points.

[0041] The data receiving module is used to receive source group data sent by the source group through the central communication component corresponding to the source group communication component that sends source group data.

[0042] The instruction generation module is used to generate control instructions based on the source group data and time-distance rules;

[0043] The instruction sending module is used to determine the radio signal coverage status of the seismic source group, and send control instructions to the seismic source group through the central communication component selected according to the radio signal coverage status, so that the seismic source group can control the vibration status according to the control instructions.

[0044] This invention provides a seismic source device, comprising:

[0045] The path receiving module is used to receive the travel path of the seismic source group and the coverage status of the central radio signals at the path points sent by the control center through the seismic source communication component. The seismic source group communication component includes a seismic source radio and a seismic source satellite component.

[0046] The data transmission module is used to determine the radio signal coverage status of the seismic source group at specified time intervals based on the location information of the seismic source group and the central radio signal coverage status of the path point; and to send the seismic source group data to the control center through the seismic source communication component selected according to the radio signal coverage status.

[0047] The command receiving module is used to receive control commands through the source communication component corresponding to the central communication component that sends control commands to the control center; and to control the vibration state according to the control commands.

The invention also receives the source group data sent by the seismic source group through a central communication component corresponding to the source group's data transmission component. This enables data exchange between the control center and the seismic source group when the source group is in a shadowed area. Control commands are generated based on the source group data and time-distance rules; the radio signal coverage status of the seismic source group is determined, and the control commands are sent to the seismic source group through a central communication component selected based on the radio signal coverage status. This allows the seismic source group to control the seismic state according to the control commands.

[0064] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0065] To address the problems existing in the prior art, embodiments of the present invention provide a method, apparatus, medium, and equipment for controlling the vibration of a source group.

[0066] Example 1

[0067] Embodiment 1 of the present invention provides a method for controlling the vibration of a source group, the process of which is as follows: Figure 1 As shown, it includes the following steps:

[0068] Step S101: Plan the driving path of the seismic source group based on the terrain data and the seismic source group identifier.

[0069] In this embodiment, the control center plans the driving path of the seismic source group based on terrain data and seismic source group identifiers. Specifically, the control center determines several driving paths based on the highest point, lowest point, maximum elevation difference, slope, and coordinates of the terrain, and plans the driving path of the seismic source group based on these driving paths and the seismic source group identifiers.

[0070] Step S102: Based on the location information of the control center and the travel path of the seismic source group, determine the coverage status of the central radio station signal at the path points in the travel path.

[0071] In this embodiment, the control center determines the coverage status of the central radio signal at path points along the travel path based on its own location information and travel path. Specifically, the control center determines the slope of the path points along the path of the seismic source group when they are ahead of the control center, based on its own location information and the travel path of the seismic source group; it then compares the slope of the path point with a slope threshold; if the slope is less than the slope threshold, the central radio signal at the path point is covered; if it is not less than the slope threshold, the central radio signal at the path point is not covered.

[0072] The slope threshold is determined based on the actual conditions of the work area. In this embodiment, the slope threshold is 15°, but other values ​​can be used for different work areas. The control center determines the slope threshold based on the terrain data of the work area. Figure 2 The travel path of the earthquake source group shown; Figure 2 The overall representation indicates the terrain of the work area. Figure 2 The red lines in the diagram represent the trajectory of the earthquake source group.

[0073] Step S103: The radio signal coverage status of the driving path and waypoints is sent to the seismic source group through the central communication component. The central communication component includes a central radio station and a central satellite component; this allows the seismic source group to determine its own radio signal coverage status based on its location information, the driving path, and the radio signal coverage status of the waypoints.

[0074] In this embodiment, the control center sends the radio signal coverage status of the driving path and path points to the seismic source group via the central communication component. This allows the seismic source group to determine its own radio signal coverage status based on its location information, the driving path, and the radio signal coverage status of the path points. Specifically, the control center sends the radio signal coverage status of the seismic source group's driving path and path points to the seismic source group via the central radio and central satellite components. This allows the seismic source group to determine its own radio signal coverage status based on its location information, the driving path, and the radio signal coverage status of the path points.

[0075] Step S104: Receive the source group data sent by the source group through the central communication component corresponding to the source group communication component that sends source group data.

[0076] In this embodiment, the control center receives the source group data sent by the source group through a central communication component corresponding to the source group's data transmission component. Specifically, if the source group's central radio signal provides coverage, the source radio station is selected to send source group data to the control center, and the control center receives the source group data sent by the source group through the central radio station; if the source group's central radio signal does not provide coverage, the source satellite component is selected to send source group data to the control center, and the control center receives the source group data sent by the source group through the central satellite component.

[0077] When the control center receives data from the seismic source group, it can determine the time difference between the moment the data is received and the moment the travel path is sent to the seismic source group. This time difference is compared to a preset time difference. If the time difference is greater than the preset time difference, the control center re-determines the travel path of the seismic source group and the central radio signal coverage status of the path points, sending this information to the seismic source group via the central communication component, and discards the received data. If the time difference is not greater than the preset time difference, the received data is retained. The preset time difference is determined based on actual conditions. This ensures the accuracy of the seismic source group's travel path and the accuracy of the central radio signal coverage status of the path points when the control center's location changes.

[0078] Step S105: Generate control commands based on source group data and time-distance rules.

[0079] In this embodiment, the control center generates control commands based on the source group data and time-distance rules. Specifically, the control center generates control commands based on the source group identifier, blasting conditions, and time-distance rules in the source group data.

[0080] Step S106: Determine the radio signal coverage status of the seismic source group, and send control commands to the seismic source group through the central communication component selected according to the radio signal coverage status; so that the seismic source group can control the vibration status according to the control commands.

[0081] In this embodiment, the control center determines the radio signal coverage status of the seismic source group. The control center then sends control commands to the seismic source group via a central communication component selected based on the radio signal coverage status, enabling the seismic source group to control its vibration state according to the control commands. Specifically, the control center determines the point on the travel path where the control command is generated at the time the seismic source group receives data, the time the control command is generated, the speed of the seismic source group in the data, and the travel path of the seismic source group. The control center determines the radio signal coverage status of the seismic source group based on the point on the travel path and the central radio signal coverage status at that point. The control center selects a central communication component based on the radio signal coverage status of the seismic source group and sends control commands to the seismic source group via the selected central communication component, enabling the seismic source group to control its vibration state according to the control commands. This ensures that during the time period between the seismic source group sending data and receiving control commands, the seismic source group can receive control commands when traveling from the non-shaded area to the shaded area.

[0082] After the control center sends control commands to the seismic source group, it can also re-determine the travel path of the seismic source group and the central radio signal coverage status of the path points based on the seismic source group's location in the data, and send this information to the seismic source group via the central communication component. This further ensures the accuracy of the seismic source group's travel path and the accuracy of the central radio signal coverage status of the path points when the control center's location changes.

[0083] One specific implementation process in this embodiment is as follows:

[0084] The control center plans the first, second, third, and fourth driving paths for the first, second, third, and fourth seismic source groups based on the highest point, lowest point, maximum elevation difference, slope, coordinates, and seismic source group identifiers of the work area.

[0085] When a waypoint is ahead of the control center, the control center determines the slope of the waypoints in the first, second, third, and fourth driving paths to be 5°, 10°, 15°, and 18°, respectively. The slope threshold is set to 15° based on actual conditions. The slopes of the waypoints in the first, second, third, and fourth driving paths are compared with 15°; the central radio signal covers the waypoints in the first and second driving paths; the central radio signal does not cover the waypoints in the third and fourth driving paths.

[0086] The control center transmits the travel paths of the first, second, third, and fourth seismic source groups, as well as the coverage status of the central radio signals at the waypoints along those paths, to the first, second, third, and fourth seismic source groups via central radio and central satellite components.

[0087] The control center receives source group data transmitted by the first and second source groups via the source radio station; and receives source group data transmitted by the third and fourth source groups via the source satellite module via the central satellite module.

[0088] The control center determines the time difference based on the reception times of the data from the first, second, third, and fourth source groups and the times when the travel paths of the source groups are sent to them. The time difference of the first, second, third, and fourth source groups is compared with a preset time difference, which is determined based on the actual situation. If the time difference of the first, second, third, and fourth source groups is less than the preset time difference, the data from the first, second, third, and fourth source groups is retained.

[0089] The control center generates control commands for the first, second, third, and fourth seismic source groups based on the data from the first, second, third, and fourth seismic source groups, as well as time-distance rules.

[0090] The control center determines the path point of the first source group on the travel path at the time the control command for the first source group is generated, based on the reception time of the data from the first source group, the time of generating the control command for the first source group, the velocity of the source group in the data from the first source group, and the travel path of the first source group. The control center determines the path point of the second source group on the travel path at the time the control command for the second source group is generated, based on the reception time of the data from the second source group, the time of generating the control command for the second source group, the velocity of the source group in the data from the second source group, and the travel path of the second source group. The control center determines the path point of the third source group on the travel path at the time the control command for the third source group is generated, based on the reception time of the data from the third source group, the time of generating the control command for the third source group, the velocity of the source group in the data from the third source group, and the travel path of the third source group. The control center determines the path point of the fourth source group on the travel path at the time the control command for the fourth source group is generated, based on the reception time of the data from the fourth source group, the time of generating the control command for the fourth source group, the velocity of the source group in the data from the fourth source group, and the travel path of the fourth source group.

[0091] Based on the route points of the first, second, third, and fourth seismic source groups along the driving path and the coverage status of the central radio signals at those route points, the control center determined that the central radio signals of the first and second seismic source groups were covered, while the central radio signals of the third and fourth seismic source groups were not covered.

[0092] The control center selects a central radio station based on the coverage of the central radio signals for the first and second source groups; the control center then transmits control commands for the first and second source groups via the central radio station. Conversely, the control center selects a central satellite module based on the lack of coverage by the central radio signals for the third and fourth source groups; the control center then transmits control commands for the third and fourth source groups via the central satellite module.

[0093] It should be noted that this embodiment is based on the control center side.

[0094] This embodiment plans the travel path of the seismic source group based on terrain data and source group identification; determines the central radio signal coverage status of the path points based on the control center's location information and the travel path; and sends the travel path and the radio signal coverage status of the path points to the seismic source group through a central communication component, which includes a central radio and a central satellite component. This allows the seismic source group to determine its own radio signal coverage status based on its location information, travel path, and the radio signal coverage status of the path points. The embodiment also receives the seismic source group data sent by the control center through a central communication component corresponding to the seismic source group's data transmission component. This enables data exchange between the control center and the seismic source group when the seismic source group is in a shaded area. Control commands are generated based on the seismic source group data and time-distance rules; the radio signal coverage status of the seismic source group is determined, and the control commands are sent to the seismic source group through a central communication component selected based on the radio signal coverage status. This allows the seismic source group to control the seismic state according to the control commands. This achieves control of the seismic source group by the control center when the seismic source group is in a shaded area, and completes the acquisition of seismic data when the seismic source group is in a shaded area.

[0095] Example 2

[0096] Embodiment 2 of the present invention provides a method for controlling the vibration of a source group, the process of which is as follows: Figure 3 As shown, it includes the following steps:

[0097] Step S301: Receive the travel path of the seismic source group and the coverage status of the central radio signals at the path points from the control center via the seismic source communication component. The seismic source group communication component includes a seismic source radio station and a seismic source satellite component.

[0098] In this embodiment, the source group receives information from the control center regarding its travel path and the coverage status of the central radio signals at its waypoints via a source communication component. This source group communication component includes a source radio station and a source satellite component. Specifically, the source group receives information from the control center regarding its travel path and the coverage status of the central radio signals at its waypoints via both the source radio station and the source satellite component.

[0099] Step S302: At a specified time interval, determine the radio signal coverage status of the source group based on the location information of the source group and the central radio signal coverage status of the path point; and send the source group data to the control center through the source communication component selected based on the radio signal coverage status of the source group.

[0100] In this embodiment, the seismic source group determines its own radio signal coverage status at specified time intervals based on its location information and the coverage status of the central radio signals at path points along its travel path; and sends the seismic source group data to the control center through a seismic source communication component selected based on its own radio signal coverage status. Specifically, at specified time intervals, the seismic source group determines its own path points along its travel path based on its location information, and determines its own radio signal coverage status based on the path points and the coverage status of the central radio signals at those path points; if the central radio signals at a path point do not cover the area, its own radio signal does not cover the area, and it selects a seismic source satellite component and sends the seismic source group data to the control center; if the central radio signals at a path point cover the area, its own radio signal covers the area, and it selects a seismic source radio station and sends the seismic source group data to the control center.

[0101] Step S303: Receive control commands through the source communication component corresponding to the central communication component that sends control commands to the control center; control the vibration state according to the control commands.

[0102] In this embodiment, the source group receives control commands through a source communication component corresponding to the central communication component that sends control commands to the control center; and controls the vibration state according to the control commands. Specifically, the source group receives control commands sent by the control center through the central radio via a source radio; the source group also receives control commands sent by the control center through the central satellite component via a source satellite component; and controls the vibration state according to the control commands.

[0103] One specific implementation process in this embodiment is as follows:

[0104] The first, second, third, and fourth source groups received the central radio signal coverage status of the travel paths and waypoints of the first, second, third, and fourth source groups from the control center via source radio stations and source satellite components.

[0105] At specified time intervals, the first, second, third, and fourth source groups determine their waypoints along the travel path based on the location information of the source groups; the first and second source groups determine their radio signal coverage based on the coverage of the central radio signals at the waypoints along the travel path; and the third and fourth source groups determine their respective central radio signal coverage based on the lack of coverage at the waypoints along the travel path.

[0106] The first and second source groups selected their respective source radio stations based on the coverage of their radio signals. These stations then transmitted their data to the control center. The third and fourth source groups selected their respective source satellite components based on the areas where their radio signals did not cover the affected areas. These components then transmitted their respective data to the control center.

[0107] The first and second source groups receive control commands from the control center via the central radio station through the source radio station, while the third and fourth source groups receive control commands from the control center via the central satellite module through the source satellite module. The first, second, third, and fourth source groups control their own vibration states according to the control commands from the first, second, third, and fourth source groups, respectively.

[0108] It should be noted that this embodiment is based on the source group side.

[0109] Example 3

[0110] Embodiment 3 of the present invention provides a method for controlling the vibration of a source group, the process of which is as follows: Figure 4 As shown, it includes the following steps:

[0111] Step S401: The control center plans the driving path of the seismic source group based on the terrain data and the seismic source group identification.

[0112] Step S402: The control center determines the coverage status of the central radio station signal at the path points along the travel path based on its own location information and the travel path of the seismic source group.

[0113] Step S403: The control center transmits the radio signal coverage status of the driving path and waypoints to the seismic source group via the central communication component. The central communication component includes a central radio station and a central satellite component.

[0114] Step S404: The source group receives information from the control center regarding the source group's travel path and the coverage status of the central radio signals at the path points via the source communication component. The source group communication component includes a source radio station and a source satellite component.

[0115] Step S405: Every specified time interval, the source group determines its own radio signal coverage status based on its location information and the central radio signal coverage status of the path point; and sends the source group data to the control center through the source communication component selected based on its own radio signal coverage status.

[0116] Step S406: The control center receives the source group data sent by the source group through the central communication component corresponding to the source group communication component that sends the source group data.
