Description

Technical Field

[0001] This invention relates to the field of seismic geological exploration technology, particularly to the field of resource exploration such as oil, natural gas, and coal, and especially to a method, device, equipment, and related system for controlling seismic source excitation. Background Technology

[0002] Currently, seismic exploration is the primary method for onshore oil, natural gas, and coal resource exploration. Traditional excitation sources (explosives) are the main excitation type in seismic exploration and are widely used in onshore exploration projects, especially in mountainous areas where explosive source excitation plays an irreplaceable role. The source excitation synchronization control system (hereinafter referred to as the source excitation synchronization equipment) consists of encoders and decoders. One encoder controls multiple decoders, and the control of the source excitation process and the transmission of excitation quality control data are all communicated via radio. Specifically, during field operations, the encoder connects to the seismic instrument host, receives the shot point excitation command from the host, encodes it accordingly, and sends it to the decoder via wireless communication. After receiving and parsing the excitation command from the encoder, the decoder controls the shot point excitation and returns the corresponding quality control information to the encoder. Upon receiving the quality control information, the encoder directly forwards it to the seismic instrument host, thus achieving synchronization between the source initiation and the seismic information received and recorded by the seismic instrument host.

[0003] As onshore seismic exploration continues to deepen, the area of ​​field seismic data acquisition is becoming larger and larger, and the construction surface is becoming increasingly complex. This places higher demands on traditional seismic source excitation methods, not only in terms of the requirements for radio signal transmission distance and reliability, but also in terms of the number of decoders and their management efficiency during construction.

[0004] Currently, commonly used source excitation synchronization equipment in land seismic exploration includes INOVA's Shotpro II and Seismic Source's BoomBox. During field seismic acquisition, an encoder is typically connected to the main seismic instrument, controlling multiple decoders to perform source excitation according to the main unit's instructions. The encoder is usually mounted on the instrument vehicle housing the main system, while the decoders for blasting within the work area are distributed within the effective communication range of the instrument vehicle's radio. The radio is typically an analog radio, such as a Motorola GM338. Summary of the Invention

[0005] The inventors discovered that with the continuous development of onshore seismic exploration, especially the increasing scale of field seismic data acquisition, the drawbacks of this operational mode have become increasingly prominent: First, the number of decoders has gradually become a bottleneck limiting excitation efficiency. For example, the encoder of the Shotpro II source excitation synchronization equipment can only control a maximum of 14 decoders for source firing operations. Using 15 or more decoders can easily result in "double firing," severely restricting field production efficiency and posing significant quality control risks. With the gradual large-scale application of "two wide and one high" (wide azimuth, wide bandwidth, high density) acquisition technology, there will be higher requirements for the number of decoders used and the efficiency of source excitation operations. The demand for decoders in field seismic data acquisition will far exceed 15 units. Second, there are issues with radio communication distance and reliability. Currently, the analog communication radios used in source excitation synchronization equipment have a communication distance of about 15km in open areas, and the communication effect is greatly reduced in complex terrain areas such as mountains and jungles. To solve the problem of radio communication distance, the coverage of radio signals is usually increased by setting up repeater radios or raising the communication antenna, but the actual effect is not ideal.

[0057] 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.

[0058] This invention provides a source excitation control method, which can be executed by a source excitation controller, the controller being communicatively connected to the encoder in a source excitation synchronization device. (Refer to...) Figure 1 As shown, the method may include the following steps:

[0059] Step S11: Receive the detonation request sent by the encoder. The detonation request is generated by the decoder connected to the encoder.

[0060] It should be noted that the seismic source excitation synchronization device in this embodiment of the invention includes: an encoder and multiple decoders connected thereto. The decoders generate a detonation request, which can be a "ready" signal. (In conjunction with...) Figure 2As shown, after the decoder generates the detonation request, it will send the request information to the encoder in the same group via radio. Those skilled in the art will understand that the encoder and decoder in the source excitation synchronization device are the same group of synchronization control devices, and they can only transmit information within the group. Encoders in different groups cannot transmit data to decoders in other groups.

[0061] Reference Figure 2 As shown, the aforementioned source excitation synchronization equipment in this group includes: encoder 201 and decoders 1001, 1002, ..., 1014. The decoders send a "ready" signal to encoder 201, which then sends the detonation request to the source excitation controller connected to it. As can be seen from the diagram, 01 is the source excitation controller, connected to terminal 101 via WIFI or other wireless communication methods. The source excitation controller is connected to encoder 201 via a data interface. 1001, 1002, ..., 1007, 1008, 1009, and 1014 are decoders. These devices constitute a group for excitation control based on grid management.

[0062] Step S12: Generate a firing point activation command based on the detonation request, and send the firing point activation command to the corresponding decoder through the encoder so that the decoder controls the firing point connected to it to detonate.

[0063] In this embodiment of the invention, a shot point excitation command is generated based on the aforementioned detonation request. For a set of source excitation synchronization devices, the shot point excitation command can be generated according to the detonation request and preset working timing parameters. The timing signal in the aforementioned working timing parameters is a marker used to determine which micro-operations are performed within a time period. It specifies when this micro-operation is issued. The timing signal is a signal with time on the horizontal axis, that is, a signal in the time domain, allowing observation of the signal's time-domain characteristics.

[0064] In this embodiment of the invention, according to the detonation request, a firing command for the firing point is automatically generated according to the pre-configured working timing parameters, such as an "ignition" signal command, and sent to the encoder. The encoder then activates the decoder via a radio to fire the firing point.

[0065] Step S13: Collect the quality control data received by the encoder.

[0066] In this embodiment of the invention, the decoder returns corresponding quality control data to the encoder after the shot point is excited. After receiving the quality control data, the encoder directly sends it to the source excitation controller so as to perform quality control during the excitation process.

[0067] Step S14: Mark the quality control data.

[0068] In this embodiment of the invention, the above-mentioned quality control data also needs to be marked with timestamps to facilitate the overall management and control of the gridded seismic data acquisition.

[0069] The source excitation control method provided in this embodiment of the invention is more suitable for the needs of large-scale exploration compared to the existing method of generating shot point excitation commands through the seismic instrument host. Since the existing control logic involves the encoder in the source excitation synchronization device transmitting the detonation request sent by the decoder, the inventors of this embodiment have eliminated the limitations of the seismic instrument host by generating the shot point excitation command through the source excitation controller. This avoids the limitations of traditional source excitation, which only allows for one encoder, and the requirement for a large number of decoders in field seismic data acquisition. The source excitation controller described above can significantly improve construction efficiency.

[0070] In one specific embodiment, refer to Figure 3 and Figure 2 As shown, after the acquisition begins, the autonomous control of the acquisition process can include the following steps:

[0071] Step S31: Configure control parameters. In this step, terminal 101 is used to configure the control parameters of the control module in the source excitation controller 01, and the working mode is changed to autonomous mode. When configuring the above control parameters in this step, it is also necessary to obtain the model (synchronization control device model), start-up delay parameters, working timing parameters, control protocol, etc. of the source excitation synchronization equipment (encoder, decoder, and radio, etc.) connected to it.

[0072] Step S32: Configure acquisition parameters. In this step, terminal 101 is used to configure the acquisition parameters of the acquisition module in the source excitation controller 01, including sampling interval, preamplifier gain, filter type, etc.

[0073] It should be noted that the execution order of the above steps S31 and S32 is not important. Step S31 can be executed first and then step S32, or step S32 can be executed first and then step S31, or steps S31 and S32 can be executed simultaneously. This embodiment of the invention does not impose any specific limitations on this.

[0074] Step S33: Initialization to synchronize the local clock with the satellite time. After the seismic source excitation controller 01 is powered on, it performs initialization. During the initialization process, the local clocks of the control module and the sampling module are synchronized with the satellite time.

[0075] Step S34: Determine whether the seismic source excitation controller has received a detonation request; if so, proceed to step S35. For example, whether the seismic source excitation controller has received a "ready" signal as in step S11.

[0076] Step S35: Generate a firing command based on the detonation request. For example, when encoder 201 sends the "ready" signal received from decoders (1001, 1002, ..., 1007, 1008, 1009, 1014) to source excitation controller 01, the control module in source excitation controller 01 will automatically send an "ignition" signal to encoder according to the pre-configured working timing parameters, thereby starting the decoder to excite the firing point.

[0077] In this embodiment of the invention, when there are multiple sets of source excitation controllers and encoders, each encoder is isolated by different "team numbers" or "start codes" for detonation, and the decoder numbers within the same group are not repeated, ensuring that source excitation controllers and encoders in different groups can only start the decoders within their respective groups within their respective excitation sequences, thereby fundamentally eliminating the phenomenon of overlapping artificial seismic waves.

[0078] Step S36: Acquire the quality control data received by the encoder. During the excitation process, the acquisition module in the source excitation controller 01 records quality control signals such as TimeBreak, marks the timestamp (accurate to microseconds), and stores it locally.

[0079] Step S37: After the excitation is completed, the source excitation controller 01 sends the latest completed excitation point location, excitation time (accurate to microseconds), excitation status and other key quality control information to the terminal 101 via WiFi or other wireless communication methods.

[0080] Step S38: After the daily data collection task is completed, use terminal 101 to output a report file containing information such as excitation time, excitation point location, and excitation status.

[0081] Step S39: Download the data recorded by the acquisition module in the seismic source excitation controller 01, use the shift report information in step S38, and use dedicated software to separate and extract auxiliary data for quality control.

[0082] In this embodiment of the invention, multiple sets of source excitation synchronization devices are coordinated to work simultaneously based on satellite timing technology, providing a solution for shot point excitation control using multiple source excitation synchronization devices for field seismic exploration operations. This eliminates the need for the encoder to operate simultaneously on a limited number of 15 source excitation synchronization device decoders.

[0083] In one specific embodiment, refer to Figure 4 and Figure 5 As shown, after the acquisition begins, the centralized control for triggering the acquisition can include the following method flow:

[0084] Step S401: Configure control parameters. In this step, terminal 101 is used to configure the control parameters of the control module in the source excitation controller 01, changing the working mode to centralized control mode; at the same time, terminal 102 is used to configure the control parameters of the control module in the source excitation controller 02, changing the working mode to centralized control mode; the specific implementation of this step can refer to step S31 above, and will not be repeated here.

[0085] Step S402: Configure acquisition parameters. In this step, terminal 101 is used to configure the acquisition parameters of the acquisition module in the seismic source excitation controller 01; terminal 102 is used to configure the acquisition parameters of the acquisition module in the seismic source excitation controller 02. The specific implementation of this step can be referred to step S32 above, and will not be repeated here.

[0086] Step S403: Select the terminal working mode. This step involves setting the terminals matched with multiple seismic source excitation controllers used for grid management to master mode, and setting the other terminals to slave mode.

[0087] Step S404: Power-on initialization. The specific implementation of this step can be referred to step S33 above, and will not be repeated here. The seismic source excitation controller is connected to the terminal and is used to control the encoder startup, and can record, display, and output key information during the shot point excitation operation, such as the excitation point location, excitation time, and excitation status. Satellite time synchronization, i.e., time synchronization operation is performed according to a predetermined cycle, to ensure that the local clock does not drift significantly, and the time accuracy of the excitation control can meet the requirements of seismic exploration; strict excitation timing division is achieved based on satellite time synchronization technology, avoiding the overlap of artificial seismic waves when using multiple encoders.

[0088] Step S405: Determine whether the seismic source excitation controller has received a detonation request; if so, proceed to step S406.

[0089] Step S406: Send the detonation request to the terminal.

[0090] Step S407: Determine the terminal mode; if it is the main mode, proceed to step S408; otherwise, proceed to step S409.

[0091] Step S408: Generate the firing command based on the detonation request. It should be noted that in this step, since the detonation requests are sent by multiple different sets of seismic source excitation synchronization devices, such as decoders 1001, 1002-1014 and decoders 2001, 2002-2014, the generation of the firing command will differ from step S35 above.

[0092] That is: receive other detonation requests sent by other encoders, which are generated by decoders connected to other encoders; and generate firing commands based on the detonation requests, other detonation requests, firing progress, current time, record length, two-shot interval time, and encoder start delay parameters.

[0093] Step S409: Forward to the master mode terminal. When the terminal set to "slave mode" receives the detonation request information from the corresponding source excitation controller, it immediately forwards it to the terminal set to "master mode". In this embodiment of the invention, the terminal set to "master mode" calculates the corresponding excitation time based on the current excitation progress, current satellite time, recording length, two-shot interval time, encoder start delay parameters, etc., and sends it to the terminal set to "slave mode". The terminal controls the corresponding source excitation controller to start the encoder according to the specified excitation time to achieve shot point excitation. When the terminal set to "master mode" receives the information from the corresponding source excitation controller, it immediately calculates the corresponding excitation time based on the current excitation progress, current satellite time, recording length, two-shot interval time, encoder start delay parameters, etc., and controls the corresponding source excitation controller to start the encoder according to the time to achieve shot point excitation.

[0094] Step S410: Receive the shot point activation command sent by the main mode terminal. It should be noted that in this embodiment of the invention, the same source activation controller's control module generates shot point activation commands for different groups of detonation requests, avoiding activation time conflicts or excessively long intervals that could affect the accuracy of seismic data. That is, when there are multiple sets of source activation controllers and encoders, each encoder is isolated from others by using different "team numbers" or "start codes," and the decoder numbers within the same group are not repeated, ensuring that source activation controllers and encoders in different groups can only activate the decoders within their respective groups during their respective activation sequences, fundamentally preventing the phenomenon of overlapping artificial seismic waves.

[0095] Step S411: Send the matching signal from the mode terminal to the source excitation controller.

[0096] Step S412: Collect the quality control data received by the encoder.

[0097] Step S413: Send to the terminal.

[0098] Step S414: Terminal output and report.

[0099] Step S415, Quality Control.

[0100] Steps S412 to S415 can be modified from steps S36 to S39, and will not be repeated here in this embodiment of the invention.

[0101] Compared with the prior art, the present invention has the following obvious advantages and beneficial effects:

[0102] 1. By adopting a grid-based excitation control method, the limitation of traditional seismic source excitation having only one encoder and the requirement for a large number of decoders for field seismic data acquisition are solved, greatly improving construction efficiency;

[0104] 3. Due to the use of satellite communication technology, the time-series control method based on satellite time fundamentally eliminates the phenomenon of overlapping artificial seismic waves during seismic exploration excitation operations, thus ensuring high-quality field seismic data acquisition.
