[0002] Currently, in onshore oil seismic exploration, efficient vibroseis excitation technology based on time-distance (TD) rules is widely used for field seismic data acquisition. To ensure that source operations meet TD rules, a centralized blasting management model is typically used in the field. This involves the source transmitting various status information via radio to a central control system, which then analyzes and determines the information based on TD rules before sending the start command back to the source. Summary of the Invention

[0003] The inventors of this application have discovered that in the existing centralized blasting management mode, each source scanning excitation requires information exchange and TD rule analysis between the source and the central control system. This centralized control mode takes a certain amount of time for information exchange and rule analysis, about 2 seconds each time, and also requires a large amount of communication resources and has a relatively large signaling overhead.

[0018] An embodiment of the present invention further provides a vibroseis excitation control method, comprising:

[0019] In response to a first instruction sent by the central control system, a centralized blasting mode is started; the centralized blasting mode needs to follow a time-distance (TD) excitation rule; or

[0020] In response to the second instruction sent by the central control system, an unconstrained blasting mode is started; the unconstrained blasting mode does not need to follow the TD excitation rule.

[0021] In some optional embodiments, after starting the centralized blasting mode, the process further includes:

The blasting scanning operation is performed based on the scanning start time and the scanning quality control information is reported to the central control system;

[0023] After the unconstrained blasting mode is started, the method further includes: upon reaching the blasting point, autonomously triggering the blasting scanning operation according to preset rules and reporting the scanning quality control information to the central control system.

When the controllable vibrator is controlled by TD rules, a centralized blasting mode is adopted. During each blasting operation, information exchange is required between the vibrator and the central control system. When the controllable vibrator is not controlled by TD rules, an unconstrained blasting mode is adopted. There is no need for information exchange between the vibrator and the central control system, and the vibrator can be autonomously controlled to perform blasting operations. Through hybrid control of the vibrator operation, unnecessary communication between the vibrator and the central control system during unconstrained blasting is eliminated, effectively reducing information exchange between the vibrator and the central control system, reducing the information exchange time of blasting operations, and improving the effective operation time and operation efficiency of the vibrator. At the same time, it can also reduce the signaling overhead between the vibrator and the central control system, saving network communication resources.

[0051] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0052] Since the centralized control mode used in the existing technology for source excitation has problems such as long occupancy time and high resource consumption, in order to solve the shortcomings of the current centralized control source operation mode, an embodiment of the present invention provides a controllable source excitation control method. When the controllable source adopts TD rule control to perform efficient operation, targeted control is performed according to the distribution of the source. By adopting a mixed control method for different sources, the source operation efficiency is effectively improved.

[0053] Furthermore, with the advancement of highly efficient aliasing data separation technology for vibroseis acquisition, the ability to separate signal and noise has been significantly improved, allowing for more relaxed TD rules to improve operational efficiency and significantly increasing the possibility of hybrid control. For example:

[0054] like Figure 1 As shown in the example diagram of the TD rule for early vibroseis excitation, the early source spacing is 8-12 kilometers to allow unconstrained excitation, that is, different sources can be excited synchronously without considering the influence of other sources, that is, Figure 1 When the source spacing is small, alternating scanning or sliding scanning is required.

[0055] Now the spacing of synchronous excitation sources has been relaxed to 0.5-1 km, such as Figure 2 As shown, the source spacing is between 0.5 and 1 km, which is unconstrained excitation. Figure 2Autonomous scanning is performed in the process, and sliding scanning is required when the distance is less than 0.5 kilometers.

[0056] During field operations, the source groups are usually placed at intervals of 2-3 kilometers, such as Figure 3 The figure shows an example of the source distribution, in which the three thick solid lines on the top and the three thick solid lines on the bottom represent the simplification of the middle part, that is, the three thick solid lines on the top correspond to the source distribution of an example in the middle part, and the three thick solid lines on the bottom also correspond to the source distribution of an example in the middle part. Taking the source distribution in the trivial matters in the middle part as an example, it includes the operating trajectories of six source vehicles. The distance between two adjacent source vehicles among source vehicle 01 (vib01), source vehicle 02 (vib02), source vehicle 03 (vib03), source vehicle 04 (vib04), source vehicle 05 (vib05) and source vehicle 06 (vib06) is 2km. Each source vehicle carries out blasting operations at each blast point in the direction indicated by the solid line with the arrow (the point next to the solid line is the blast point). When the six source vehicles operate synchronously, the distance between each other is maintained at 2km. In most cases where the positional pairs do not change much, the seismic source can perform unconstrained operations without being restricted by the distance-time requirements. In this case, if a decentralized mode of operation can be adopted to reduce the information interaction between the seismic source and the central control system, the time for information exchange and analysis and judgment between the seismic source and the central control system can be saved, thereby improving the efficiency of the seismic source operation.

[0057] The implementation process of the controllable vibrator excitation control method provided in this application is described in detail below through specific embodiments.

[0058] Example 1

[0059] The first embodiment of the present invention provides a control method for vibrator excitation control, which mainly describes the control process on the central control system side. Figure 4 As shown, the following steps are included:

[0060] Step S101: According to the spatial distribution of the earthquake source, determine whether the earthquake source needs to follow the TD excitation rule.

[0061] The central control system determines whether the seismic sources require TD excitation based on their spatial distribution, thereby determining which sources require and do not need to follow the TD excitation rule. Specifically, the distance between adjacent seismic sources is determined based on their locations. If the distance between a source and an adjacent source is less than the synchronous excitation distance threshold, the TD excitation rule must be followed. If the distance between a source and an adjacent source is not less than the synchronous excitation distance threshold, the TD excitation rule is not followed.

[0062] The synchronous excitation distance threshold refers to the spacing distance that each source needs to meet to independently perform scanning excitation without considering the excitation state of adjacent sources. The synchronous excitation distance threshold can be set according to the allowable spacing of synchronous excitation of sources. For example, it can be 0.5-1 km or other values.

[0063] Step S102: For a seismic source that needs to follow the TD excitation rule, a first instruction is sent to the seismic source so that the seismic source starts a centralized blasting mode according to the first instruction.

[0064] For a seismic source that needs to follow the TD excitation rule, the central control system will send a first instruction to the seismic source to inform it that it needs to follow the TD excitation rule and that the seismic source needs to adopt a centralized blasting mode.

[0065] Step S103: For the seismic source that does not need to follow the TD excitation rule, a second instruction is sent to the seismic source so that the seismic source starts the unconstrained shooting mode according to the second instruction.

[0066] For sources that need to follow the TD excitation rules, the central control system will send a second instruction to the source to inform it that it does not need to comply with the TD excitation rules. The source can adopt an unconstrained blasting mode and conduct blasting scans independently without being constrained or restricted by the blasting time of other sources.

[0067] In some optional embodiments, after sending the first instruction to the seismic source, the method further includes:

[0068] Step S104: Receive the source status information sent by the source after it arrives at the blasting point, determine the scan start time of the source based on the source status information and send it to the source, so that the source can perform blasting and scanning operations based on the scan start time; and receive the scanning quality control information reported by the source after the blasting operation.

[0069] For seismic sources that adopt a centralized blasting mode, the seismic source needs to exchange information with the central control system every time it blasts and scans. The central control system analyzes and calculates the results based on the status information reported by the seismic source, determines the scanning start time of the seismic source, and notifies the seismic source. The seismic source operates according to the scanning start time. After the scanning operation is completed, the seismic source reports relevant information to the central control system, such as scanning quality control information.

[0070] In some optional embodiments, after sending the second instruction to the seismic source, the method further includes:

[0071] Step S105: receiving scanning quality control information reported by the seismic source after the blasting operation.

[0072] For seismic sources that use an unconstrained blasting mode, there is no need for information exchange with the central control system during blasting and scanning. The seismic source autonomously controls the scan start time to perform operations. Since it is within the distance range allowed by synchronous excitation, there will be no interference even if it is excited at the same time as other seismic sources. After the blasting operation, the seismic source will report relevant information to the central control system, such as scan quality control information.

[0073] In some optional embodiments, the above method further includes:

[0074] If it is determined based on the location information of the earthquake source that the spatial distribution of the earthquake source has changed, it is re-judged whether each earthquake source needs to follow the TD excitation rule based on the changed spatial distribution of the earthquake source, and it is determined based on the judgment result whether each earthquake source needs to adjust the firing mode, and the first instruction or the second instruction is sent to the earthquake source that needs to adjust the firing mode so that the earthquake source can adjust the firing mode.

[0075] When using a vibrator vehicle, Figure 3 As shown, although multiple seismic source vehicles can operate synchronously, sometimes some accidents may occur, resulting in the seismic source vehicles being unable to synchronize, some seismic source vehicles operating faster and some operating slower, or a seismic source vehicle malfunctioning and causing its operating progress to be inconsistent with other seismic source vehicles, etc., which will cause the relative position relationship of the seismic sources during the operation to change, and the distance to the adjacent seismic sources will also change, that is, the spatial distribution of the seismic sources has changed, which will result in the seismic sources that previously could use the unconstrained blasting mode may need to use the centralized blasting mode, or the seismic sources that used the centralized blasting mode may be able to use the unconstrained blasting mode, and the blasting mode needs to be adjusted at this time.

[0076] When the controllable source is performing operations controlled by TD rules, this method divides the source into two situations (constrained and unconstrained) according to whether the source is subject to TD rules, and adopts two different control methods (centralized and unconstrained) to manage the operation, realizing hybrid excitation management of the controllable source, thereby increasing the effective operation time of the source and further improving the efficiency of the source operation.

[0077] Example 2

[0078] The second embodiment of the present invention provides a controllable vibrator excitation control method, which mainly describes the control process on the vibrator side, such as Figure 5 As shown, the following steps are included:

[0079] Step S201: receiving instructions sent by the central control system.

[0080] Vibrators feature two modes: centralized blasting and unconstrained blasting, with automatic switching to achieve mixed excitation. Each vibrator receives commands from a central control system, either primary or secondary. Based on these commands, each group of vibrators operates according to the blasting mode determined by the central control system.

[0081] Step S202: In response to the first instruction sent by the central control system, the centralized blasting mode is started; the centralized blasting mode needs to follow the time-distance TD excitation rule.

[0082] Step S203: In response to the second instruction sent by the central control system, the unconstrained blasting mode is started; the unconstrained blasting mode does not need to follow the TD excitation rule.

[0083] In some optional embodiments, after starting the centralized blasting mode, the process further includes:

[0084] Step S204: After arriving at the shot point, the source status information is sent to the central control system, and the scan start time determined by the central control system based on the source status information is received. The shot scan operation is performed based on the scan start time and the scan quality control information is reported to the central control system.

[0085] For seismic sources that use a centralized blasting mode, information needs to be exchanged with the central control system before each blasting operation to determine the time to start the scan to avoid interference with other seismic sources.

[0086] In some optional embodiments, after starting the unconstrained blasting mode, the process further includes:

[0087] Step S205: After arriving at the shot point, the blasting and scanning operation is autonomously triggered according to the preset rules and the scanning quality control information is reported to the central control system.

[0088] The seismic source adopts the unconstrained blasting mode, which does not need to exchange information with the central control system. It can determine the time to start the scan by itself and perform the blasting operation autonomously.

[0089] The above method uses the automatic switching of the controllable source between the two excitation management modes to effectively reduce the information exchange between the source and the central control system, eliminating unnecessary radio communication delay time when the source adopts the unconstrained blasting mode. Usually, an information exchange between the source and the central control system takes 2 seconds. Using the unconstrained blasting mode, there is no need to wait for this long, thereby improving the effective operation time of the source.

[0090] Example 3

[0091] The third embodiment of the present invention provides a specific implementation process of the controllable vibrator excitation control method, the process of which is as follows: Figure 6 As shown, the following steps are included:

[0092] Step S301: The central control system determines whether the earthquake source needs to follow the TD excitation rule based on the spatial distribution of the earthquake source. If yes, step S302 is executed; if not, step S309 is executed.

[0093] The blasting management system of the controllable vibrator is configured to have two modes: centralized blasting mode and unconstrained blasting mode, and automatic switching between the two modes can be achieved.

[0094] During vibroseis acquisition, the central control system determines whether each vibrator needs to follow the TD (Time Delayed) firing rules based on their respective positions. If the central control system determines that TD rules must be followed, it sends a command to the vibrator, which selects the centralized firing mode. If the TD rules are not followed, the vibrator automatically selects the unconstrained firing mode.

[0095] When vibroseis sources are efficiently collecting data, such as when operating in accordance with TD rules, the central control system determines whether the distance between each group of sources and its nearest neighboring source group exceeds a preset synchronous excitation distance threshold, for example, 0.5 kilometers, based on the vibroseis source distribution information. If it is determined to be greater than 0.5 kilometers, the source does not need to comply with TD rules, and a command is sent to the group of sources to operate in an unconstrained blasting mode. If the distance is determined to be less than 0.5 kilometers, the source group needs to follow TD rules for blasting, and a command is sent to the group of sources to operate in a centralized blasting mode. The synchronous excitation distance threshold can be set as needed.

[0096] Step S302: The central control system sends a first instruction to the earthquake source.

[0097] The first instruction carries instruction information for instructing the source to adopt a centralized blasting mode.

[0098] Step S303: The source receives the first instruction sent by the central control system.

[0099] Step S304: The seismic source starts a centralized blasting mode in response to the first instruction sent by the central control system.

[0100] Step S305: After the seismic source reaches the shot point, the seismic source status information is sent to the central control system.

[0101] Step S306: The central control system receives the source status information sent by the source, determines the source scanning start time according to the source status information, and sends it to the source.

[0102] Step S307: The seismic source receives the scan start time sent by the central control system, performs a shot scan operation based on the scan start time, and reports the scan quality control information to the central control system.

[0103] A seismic source in centralized blasting mode will transmit relevant status information, such as readiness and location information, to the central control system via radio upon arrival at the blasting point. The central control system will analyze and calculate this information, determine its scan start time based on TD rules, and send it back to the seismic source. The seismic source will then scan according to the central control system's instructions and, upon completion, transmit relevant status information back to the central control system.

[0104] Step S308: The central control system receives the scanning quality control information reported by the seismic source.

[0105] Step S309: The source receives the second instruction sent by the central control system.

[0106] Step S310: The seismic source starts the unconstrained blasting mode in response to the second instruction sent by the central control system.

[0107] Step S311: After the earthquake source reaches the shot point, it automatically triggers the blasting and scanning operation according to the preset rules and reports the scanning quality control information to the central control system.

[0108] Step S312: The central control system receives the scanning quality control information reported by the seismic source.

[0109] If the source is selected in the unconstrained blasting mode, the scanning operation will be triggered completely autonomously. After each scan, the corresponding status information or related scanning quality control information will be sent back to the central control system.

[0110] In the above method, the central control system can determine whether to exchange control information with the seismic source based on the information sent back by the seismic source. If it receives information reported after the blasting, no information exchange is required. If it receives status information sent before the blasting, information exchange is required. If the seismic source distribution location changes, resulting in a change in its compliance with the TD rule, the central control system will re-execute step S301, re-evaluate the TD rule requirements for the seismic source, and re-send the determination result to the seismic source. The seismic source will then re-determine the blasting mode based on the new determination result and perform the operation according to the updated blasting mode. This cycle will continue until the operation is completed.

[0111] like Figure 7 As shown in the figure, it is a schematic diagram of the centralized blasting mode. In this case, no matter whether the distance between the seismic sources is within the sliding scanning range or the autonomous scanning range, signaling interaction is required between the control system in the seismic source vehicle and the central control system of the control center. The seismic source vehicle reports the state of the seismic source, and the central control system triggers the corresponding command to be sent to the seismic source.

[0112] like Figure 8The figure shows a schematic diagram of hybrid excitation control. When the source distance is less than a certain value, such as 800 meters, that is, within the sliding scanning range, a centralized blasting mode is used. Signaling interaction is required between the source control system and the central control system. The source vehicle reports the source status, and the central control system triggers the corresponding command and sends it to the source. When the source distance is larger, such as at least 800 meters, that is, within the autonomous scanning range, an unconstrained blasting mode is used. The source vehicle only needs to report the source status after the blast, and no information exchange is required between the two.

[0113] The methods of the aforementioned embodiments determine whether a source needs to follow the TD rule to control its firing timing based on the spatial distribution of the seismic sources. When a source needs to follow the TD rule, a centralized firing mode is automatically adopted. Specifically, the source transmits its firing position and status information to a central control system, which then controls the source's activation time according to the TD rule. Information is exchanged between the central control system and the source during each blast scan. When a source does not need to follow the TD rule, it automatically switches to unconstrained firing mode, where the source only needs to transmit status information after each blast back to the central control system. If changes in the spatial distribution of the seismic sources affect whether the source complies with the TD rule, firing control judgments and instructions are re-issued for all sources.

[0114] Based on the same inventive concept, the embodiment of the present invention further provides a vibrator excitation control device, which can be set in a central control system. The structure of the device is as follows: Figure 9 Shown, including:
