Description

Technical Field

[0001] The invention belongs to the field of marine oil seismic exploration, and in particular relates to a non-directional adaptive submarine cable. Background Art

[0002] Marine seismic exploration is usually carried out by artificially exciting seismic waves, and multiple submarine cables laid on the seabed receive the reflected waves from the formation. The submarine cable seismic acquisition system is aimed at the submarine seismic acquisition scenario, which solves the geophysical industry's demand for marine surveys with larger seismic channel counts. The construction advantages of high deployment flexibility, repeatable deployment, and laying on the seabed surface ensure the operation efficiency. The four-component seabed seismic acquisition can provide high-fidelity seismic data with excellent coupling. The cable body adopts DC high-voltage power supply, and the length of a single cable can reach 16km; the synchronization mechanism is GPS clock synchronization and global clock synchronization acquisition, which can provide two recording modes: single-shot synchronization acquisition and continuous acquisition. The submarine cable seismic acquisition system takes into account the efficiency of offshore construction operations and the use and maintenance costs, and pursues the maximum use value.

[0003] The underwater submarine cable acquisition system is mainly composed of one or more acquisition submarine cables, each submarine cable is mainly composed of a deck cable section 1, an intermediate cable section 2 and a tail cable section, such as Figure 1 As shown; each cable segment has several seismic wave acquisition electronics modules built in, thus forming a giant covering sensor array for measuring the seismic wave information returned by the geological layer to the seabed.

[0004] In the prior art, the direction of the submarine cable is defined as from the deck cable section to the stern cable section, the deck cable section is the front, and the stern cable section is the rear, that is, the direction from the deck cable section to the stern cable section is the direction from the front-stage cable to the rear-stage cable; the cable head end 3 of each intermediate cable section 2 is close to the deck cable section 1 and is set to the forward setting, and the cable head end 3 is far away from the deck cable section 1 and is set to the reverse setting. The connection method of several sections of each submarine cable is that the cable head end 3 of the rear-stage cable section is connected to the cable tail end 4 of the front-stage cable section, and each cable section is connected in sequence, such as Figure 1 As shown, the connection method is single. This means that when one end of the cable head of the downstream cable is inconvenient to connect, the entire submarine cable may face the problem of being unusable, thereby greatly reducing the on-site operation efficiency.

[0057] In order to better understand the purpose, structure and function of the present invention, a non-directional adaptive submarine cable of the present invention is further described in detail below with reference to the accompanying drawings.

[0058] The direction of the submarine cable is defined as from the deck cable section to the stern cable section, with the deck cable section being the front and the stern cable section being the rear, that is, the direction from the deck cable section to the stern cable section is the direction from the front-stage cable to the rear-stage cable. For the convenience of description in the following text, the right one of the two cable sections is described as the rear stage, and the left one is described as the front stage; the cable head of each intermediate cable section is set to a forward setting when it is close to the deck cable section, and a reverse setting when it is far away from the deck cable section. For the convenience of description, the cable head end to the left and the cable tail end to the right are described as forward settings in the following text, and vice versa as reverse settings.

[0059] refer to Figure 2-Figure 4 The non-directional adaptive submarine cable of the embodiment of the present invention comprises a connecting device 7, a deck cable segment 1 and a stern cable segment, a plurality of intermediate cable segments 2 are arranged between the deck cable segment 1 and the stern cable segment, and the deck cable segment 1, the stern cable segment and the intermediate cable segment 2 constitute each cable segment; when one of the plurality of intermediate cable segments 2 is reversely arranged, the intermediate cable segment 2 can be connected to its adjacent preceding cable segment and succeeding cable segment through the connecting device 7, such as Figure 2 , Figure 3When a plurality of consecutive intermediate cable segments 2 are reversely arranged, the overall cable segment formed by connecting the reversely arranged intermediate cable segments 2 can be connected to the adjacent preceding and succeeding cable segments through the connecting device 7, such as Figure 4 shown.

[0060] The intermediate cable section 2 includes a digital packet section 21, an extension section and a plurality of working sections 22, wherein: Figure 2 In the case where a digital packet segment 21 in the middle cable segment 2 is reversely set, Figure 3 In the case where a working section 22 in the middle cable section 2 is reversely arranged, Figure 4 This is the case where all the working sections 22 in the middle cable section 2 are arranged in reverse.

[0061] In the present application, the deck cable segment 1, the tail cable segment and the middle cable segment 2 constitute each cable segment. The cable tail of the front-stage cable segment can be normally connected to the cable head of the rear-stage cable segment. For example, if the front-stage cable segment is the digital packet segment 21 and the rear-stage cable segment is the working segment 22, the two can be normally connected in the connection direction of the cable tail and the cable head, such as Figure 1 When the cable head of the rear-stage cable segment is inconvenient to connect, for example, the front-stage cable segment is the digital packet segment 21, the rear-stage cable segment is the working segment, and the working segment is reversely set due to some external factors, the present application provides a connecting device 7, so that in this case, it can still ensure that the cable tail of the front-stage cable segment is normally connected to the cable tail of the rear-stage cable segment, and the cable head of the rear-stage cable segment is normally connected to the cable head of the front-stage cable segment, as shown in FIG. Figure 2-4 As shown, the on-site operation efficiency can be greatly improved.

[0062] Through the above arrangement, the embodiment of the present invention transforms the submarine cable structure in the prior art in which each cable segment must be arranged in the forward direction and connected in sequence into a non-directional adaptively connected submarine cable; through the arrangement of the connecting device 7, the arrangement direction of each intermediate cable segment 2 is not restricted, thereby improving the on-site operation efficiency.

In addition, the 1st, 3rd, 5th, 7th, and 9th acquisition stations are defined as odd paths, and the 2nd, 3rd, 6th, 8th, and 10th acquisition stations are defined as even paths. The odd path and the even path are two transmission links.

[0064] For the host computer control system corresponding to the non-directional adaptive submarine cable of this embodiment, the host computer control system is provided with serial numbers corresponding to the extension segment, the digital packet segment, and the working segment, so as to realize software identification of the reverse cable through the hardware serial number field definition and display it on the UI interface of the host computer control system.

[0065] In the software UI interface, when all cable segments are set in the forward direction, the odd path is color one and the even path is color two; when a certain intermediate cable segment is set in the reverse direction, the even path of the reversely set intermediate cable segment becomes the odd path, and the original odd path becomes the even path, that is, the odd path becomes color two and the even path becomes color one. The remaining cable segments set in the forward direction take the odd path as color one and the even path as color two as before. Figure 5 The schematic diagram shows that all cable segments are set in the forward direction, such as Figure 5 As shown, odd paths are green and even paths are blue; the schematic diagram of a certain intermediate cable segment when it is set in reverse is as follows Figure 6 As shown, Figure 6 The odd paths of the middle cable segment set in the reverse direction turn blue, and the even paths turn green. The remaining cable segments set in the forward direction take the odd paths green and the even paths blue as before.
