The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0041] Before describing the embodiments of the present application in detail, the related technologies involved in the embodiments of the present application are first described. The related technologies involved in the embodiments of the present application are applicable to the following explanations:

[0042] Marine 3D seismic data acquisition is usually completed by a ship towing a seismic source and multiple seismic streamers (buoyant cables equipped with hydrophones). Each streamer is connected by a leader section and towed by a corresponding cable winch. During the seismic data acquisition process, the ship travels in the waters above the seabed target according to a predetermined route, dragging the streamer in the direction of the survey line while exciting seismic waves through the seismic source, and the hydrophones placed in the floater in a specific arrangement record the signals transmitted from the seismic waves downward to the underground reflective layer and returned.

[0043] The embodiments of the present application provide a method, device, electronic device and storage medium for collecting seismic data. The technical solution of the present application includes: transmitting the collection command to the forwarding node through the recording system; each forwarding node transmits the collection command to the collection node at the same level and the lower-level forwarding node respectively; each collection node transmits the collection command to the lower-level collection node; each collection node collects seismic data in response to the collection command. The present application can collect large-scale seismic data at the same time through multiple collection nodes, thereby improving the collection efficiency, and the collection node structure of the present application is simple, and can be widely used in the collection of seismic data, thereby reducing the collection cost.

[0044] Reference Figure 1 The embodiment of the present application provides a seismic data acquisition method, which is applied to a seismic data acquisition system, wherein the seismic data acquisition system includes a recording system and multiple working sections, each of which includes a forwarding node and multiple acquisition nodes, each of which is connected in sequence, and each of which is connected in sequence after the forwarding node in the same working section; the method may include but is not limited to S100 to S130, which are as follows:

[0045] S100: The recording system transmits a collection command to the forwarding node.

[0046] Specifically, the recording system may send a collection command to one of the forwarding nodes via a cable between the recording system and the forwarding nodes.

[0047] S110: Each of the forwarding nodes transmits the collection command to the collection node at the same level and the forwarding node at the next level respectively.

[0048] Specifically, a forwarding node receives a collection command from a recording system, and then transmits the collection command to a lower-level forwarding node. Each forwarding node can also transmit the collection command to a collection node of a working segment at the same level.

[0049] S120: Each of the collection nodes transmits the collection command to the collection node at a lower level.

[0050] Specifically, each collection node receives a collection command from a forwarding node or an upper-level collection node of the current working segment, and then transmits it to a lower-level collection node. It is understandable that if the current collection node is the last-level collection node, the collection command may not be transmitted downward.

[0051] S130: Each of the acquisition nodes acquires seismic data in response to the acquisition command.

[0052] Specifically, each acquisition node responds to the same acquisition command and then acquires seismic data. It is understandable that multiple acquisition nodes jointly acquire seismic data, which can efficiently obtain a large amount of seismic data, thereby enriching the amount of seismic data and providing a data basis for related research.

[0053] As a further implementation, S130 may include:

[0054] S131: Each of the acquisition nodes acquires the seismic data at the same time point in response to the acquisition command.

[0055] It can be understood that the various acquisition nodes of this embodiment can acquire seismic data simultaneously, that is, accurate synchronous acquisition can be achieved, thereby improving the accuracy of seismic data.

[0056] As another optional implementation, S130 may include:

[0057] S132: Each of the acquisition nodes acquires the seismic data from the hydrophone connected to the corresponding acquisition node in response to the acquisition command.

[0058] Optionally, in this embodiment, both ends of each acquisition node may be connected to a hydrophone respectively, and the acquisition node further acquires seismic data from the signal recorded by the hydrophone.

[0059] Furthermore, the embodiment of the present application may also include the following steps:

[0060] S141: Each of the acquisition nodes transmits the acquired seismic data to the forwarding node in the same working section;

[0061] S142: The forwarding node forwards the seismic data transmitted by each of the acquisition nodes to the recording system.

[0062] It is understandable that this embodiment can upload the collected seismic data to the recording system in the reverse direction of the issuance and transmission of the acquisition command.

[0063] Next, the solution of the embodiment of the present application will be introduced and explained in detail with reference to specific application examples.

[0064] Reference Figure 2 This embodiment provides an example structure diagram of a seismic data acquisition system, based on Figure 2 The seismic data acquisition system shown illustrates the seismic data acquisition method of this embodiment.

[0065] The present invention adopts a "single leading segment-multiple working segments" right-angle comb-shaped topology structure, and develops a low-speed-high-speed hybrid pipeline data transmission model, breaking through the conventional three-dimensional seismic data acquisition and transmission and underwater equipment expansion towing mode. The data collected by multiple seismic cables are transmitted back through the underwater lumping module in one path. The data is transmitted from the lower node transmission module to the upper node transmission module in the working segment acquisition node in a low-speed single-step manner, and is transmitted to the forwarding node lumping module in the jumper segment forwarding node in a high-speed double-step manner, and uploaded to the recording system through a single leading segment. The working segment acquisition node only sends the seismic data of one acquisition node at a time, so the working segment uses a lower transmission rate; the jumper segment forwarding node sends the data of the entire working segment at a time, so the jumper segment uses a higher transmission rate. Finally, the lumping module sends the data of all acquisition nodes of the exploration system to the recording system through the leading segment.

[0066] Specifically, the seismic data acquisition system (small three-dimensional high-resolution marine seismic exploration system) of this embodiment adopts a "single leading segment-multiple working segments" right-angle comb-shaped topology structure, with 1 leading segment and 4 working segments. The length of the leading segment is 400m, and the leading segment includes optical fiber, power line and transmission line. There is 1 forwarding node, 2 acquisition nodes and multi-channel hydrophone on each working segment, and there is a jumper segment between the forwarding nodes. The forwarding node includes a forwarding module and a power module, and the acquisition node includes an acquisition module, a transmission module and a power module. The spacing of the hydrophone channel is 3.125m. The working segment is divided into 4 small segments, each of which is 37.5 meters long. The length of a single working segment is 150 meters. There are power lines, transmission lines and hydrophone signal lines inside the working segment. There is a jumper segment between the forwarding nodes, and there is no hydrophone channel inside, only power lines and transmission lines. The length of the jumper segment is 50m.

[0067] The acquisition module of the acquisition node receives the analog signals of the 12 hydrophone channels on the left and right sides of the acquisition node, converts the 24 analog signals into digital signals and sends them to the transmission module of the acquisition node. The function of the transmission module of the acquisition node is similar to that of the forwarding module of the forwarding node. It receives the synchronization information and command information transmitted by the forwarding node or the acquisition node of the current working segment, and sends the local acquisition data and the data information uploaded by the lower-level acquisition node at the same time.

[0068] The functions of the forwarding module of the forwarding node are as follows: receiving the synchronization information and command information transmitted from the upper-level forwarding node, forwarding it to the lower-level forwarding node on the one hand, and forwarding it to the collection node of the working segment at this level on the other hand; receiving the data information uploaded by the collection node of the working segment at this level and the data information uploaded by the lower-level forwarding node, and uploading this data information to the upper-level forwarding node.

[0069] Functions of the forwarding node lumped module: The lumped module and the forwarding module differ in interface. Since the lumped module needs to be connected to the leading segment for long-distance high-speed data transmission, the data between the lumped module and the recording system is transmitted via optical fiber. The lumped module is equipped with an optoelectronic transceiver module, which can convert electrical signals into optical signals and send them to the recording system via optical fiber. The other parts have the same functions as the forwarding module of the forwarding node.

[0070] Based on the right-angle comb system topology of "single leading segment-multiple working segments", the low-speed-high-speed hybrid pipeline data transmission model has a total of 4 working segments, with 2 acquisition nodes and 1 forwarding node on each working segment. Data is transmitted from the lower node transmission module to the upper node transmission module in the working segment acquisition node in a low-rate single-step manner, and is transmitted to the forwarding node aggregation module in the cross-segment forwarding node in a high-rate double-step manner, and uploaded to the recording system through a single leading segment. The working segment acquisition node only sends seismic data of one acquisition node at a time, so the working segment uses a lower transmission rate. The cross-segment forwarding node sends the data of the entire working segment at a time, so the cross-segment uses a higher transmission rate. Finally, the aggregation module sends the data of all acquisition nodes of the exploration system to the recording system through the leading segment.

[0071] The hardware structure of the acquisition node transmission module,The hardware of the acquisition node transmission module consists of FPGA, FPGA peripheral circuit, driver chip, equalization chip, isolation transformer, clock data recovery chip and power supply.

[0072] Among them, FPGA controls the entire data transmission process of the acquisition node transmission module, including the reception, identification and issuance of downlink command information, the reception and issuance of downlink synchronization information, the reception and upload of local data, and the reception and upload of data from the lower-level acquisition node.

[0073] The commands and synchronization information sent by the forwarding node first pass through the isolation transformer of the collection node transmission module, and are input into the FPGA after the signal is shaped by the equalization chip. On the one hand, the FPGA receives and parses the commands, and on the other hand, it forwards the commands and synchronization information and sends them to the lower-level collection node after passing through the driver chip and isolation transformer.

[0074] The host computer sends commands and synchronization information to the FPGA via the high-speed data transmission interface, and after being processed inside the FPGA, it is sent to the lumped module through the equalizer. The data transmitted through the optical fiber passes through the optoelectronic transceiver module, driver and FPGA, and is uploaded to the host computer through the high-speed data transmission interface for storage and display.

[0075] The beneficial effects of this embodiment include: adopting an underwater working structure with a single leader segment and multiple working cables, which has only one leader segment, and adding a forwarding node at the front end of each working segment. In terms of signal acquisition, the acquisition module and the transmission module are separated from the hydrophone channel, and one acquisition node receives the multi-channel hydrophone analog signal, which reduces the number of acquisition nodes in the system. In terms of data transmission, after the acquisition module completes data acquisition, the transmission module frames the multi-channel data and uploads it, and the forwarding node forwards the data of the entire working segment to the previous level forwarding node for upload, and uploads it to the recording system through a single leader segment. The number of working cables laid by this structure is less restricted by the facilities on board, has strong scalability and flexibility, and inherits the advantages of the multi-leader segment, multi-working segment, and multi-channel hydrophone exploration structure; only one leader segment is retained, which solves the problem of multiple leader segments being entangled near the exploration ship; at the same time, the single leader segment also leaves sufficient space for the deployment of the source system, meeting the target requirements of the small three-dimensional seismic acquisition system. In addition, from the perspective of engineering cost, the single leader segment also reduces the manufacturing cost of the system.
