[0054] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0055] Those skilled in the art will appreciate that embodiments of the present invention may be provided as methods, systems, or computer program products. Therefore, the present invention may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Moreover, the present invention may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0056] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present application and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or apparatuses.

[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] At present, the processor usually looks through each shot and each channel in front of the processor screen, relying on the eyes to identify the single shot out of the arrangement. This method has a large workload and cannot be identified in time, which affects the organization and archiving of data. The personnel are easily fatigued and cannot accurately identify, resulting in misjudgment.

[0059] In order to at least partially solve the above-mentioned technical problems in the prior art, an embodiment of the present invention provides a method for identifying out-of-sequence single shots in seismic exploration data, which can quickly and accurately identify out-of-sequence single shots in seismic data acquisition for longitudinal oil exploration by calculating the true value of a part of the time period in the single shot, effectively monitor the construction quality, do not rely on other additional data other than seismic data acquisition for oil exploration, reduce manual workload, and can timely identify and affect data collation and archiving, thereby reducing misjudgment.

[0060] In view of this, the present application provides a device for identifying out-of-order single shots in seismic exploration data, which may be a server S1, see Figure 2, the server S1 can be communicatively connected with at least one client device B1, the client device B1 can send the time period to be analyzed to the server S1, and the server S1 can receive the time period to be analyzed online. The server S1 can pre-process the acquired time period to be analyzed online or offline, obtain the absolute value of the seismic exploration acquisition data within the time period to be analyzed input by the user; sum the absolute value of the seismic exploration acquisition data of each channel; and identify the out-of-order single shot according to the absolute value and value of each channel. Then, the server S1 can send the identified out-of-order single shot online to the client device B1. The client device B1 can receive the identified out-of-order single shot online.

[0061] Also, see Figure 3 The server S1 may also be connected to at least one database server S2 for communication, and the database server S2 is used to store seismic exploration acquisition data. The database server S2 sends the seismic exploration acquisition data to the server S1 online, and the server S1 may receive the seismic exploration acquisition data online.

[0062] Based on the above content, the client device B1 may have a display interface, so that the user can view the identified out-of-order single shot sent by the server S1 according to the interface.

[0063] It is understandable that the client device B1 may include a smart phone, a tablet electronic device, a network set-top box, a portable computer, a desktop computer, a personal digital assistant (PDA), a vehicle-mounted device, a smart wearable device, etc. Among them, the smart wearable device may include smart glasses, a smart watch, a smart bracelet, etc.

[0064] In practical applications, the part of identifying out-of-order single shots in seismic exploration data can be performed on the server S1 side as described above, that is, Figure 1 The architecture shown in the figure can also be that all operations are completed in the client device B1, and the client device B1 can be directly connected to the database server S2 for communication. The specific selection can be made according to the processing capability of the client device B1 and the limitations of the user's usage scenario. This application does not limit this. If all operations are completed in the client device B1, the client device B1 can also include a processor for specific processing of out-of-order single shot recognition in seismic exploration data.

[0065] The server and the client device may communicate using any suitable network protocol, including network protocols that have not yet been developed on the filing date of this application. The network protocol may include, for example, TCP / IP protocol, UDP / IP protocol, HTTP protocol, HTTPS protocol, etc. Of course, the network protocol may also include, for example, RPC protocol (Remote Procedure Call Protocol) and REST protocol (Representational State Transfer) used on top of the above protocols.

[0066] Figure 4 Schematic diagram of the process of the method for identifying out-of-order single shots in seismic exploration data in an embodiment of the present invention Figure 1 ;like Figure 4 As shown, the method for identifying out-of-sequence single shots in seismic exploration data may include the following:

[0067] Step S100: obtaining the absolute value of the seismic exploration acquisition data within the time period to be analyzed input by the user;

[0068] The user selects the time period to be analyzed according to needs and actual conditions, such as 6S, 10S, etc.

[0069] Specifically, firstly, the time period to be analyzed input by the user is obtained, and then, the seismic exploration acquisition data within the time period to be analyzed input by the user is obtained, and then, the absolute value of the data is obtained.

[0070] Step S200: summing up the absolute value of each channel of seismic exploration acquisition data;

[0071] The absolute value of each channel is added together to obtain the absolute value and value of the data of that channel.

[0072] Step S300: Identify and arrange single shots according to the absolute value and value of each channel.

[0073] By adopting the above technical scheme, according to the sum of the absolute values ​​of the true values ​​of some time periods in a single shot, it is possible to quickly, effectively and accurately judge whether there is a drop-out phenomenon. This scheme is suitable for the single-shot quality control of seismic data acquisition in seismic data acquisition projects for oil exploration. It does not rely on other additional data, but directly uses existing data. It is simple and reliable, can reduce the labor intensity of personnel, prevent missed judgments and wrong judgments, and has good application prospects.

[0074] In an alternative embodiment, see Figure 5 The method for identifying out-of-order single shots in seismic exploration data may also include:

[0075] Step S400: decode the seismic data collected in oil exploration and load them in sequence according to the shot check points to obtain the seismic exploration acquisition data.

[0076] Among them, the seismic data for oil exploration are decoded after collection, and the data are read into the processor in sequence according to the shot check points.

[0077] In an optional embodiment, step S300 may include the following contents:

[0078] A track with an absolute value and a value of zero is identified, and a shot containing the track is identified as a de-ranked shot.

[0079] Among them, by identifying the tracks with absolute values ​​and values ​​of zero one by one, and then finding the single shot corresponding to the track, the dropped arrangement single shot is obtained, which can effectively and accurately identify the dropped arrangement single shot.

[0080] In another optional embodiment, step S300 may include the following contents:

[0081] First, calculate the product of the sum values ​​of each channel corresponding to the single shot; second, identify the single shot with a product value of zero as a single shot with a dropped arrangement.

[0082] By adopting the above technical solution, the recognition speed and efficiency of the single shot can be further improved.

[0083] In an alternative embodiment, see Figure 6 , the step S100 may include the following contents:

[0084] Step S110: obtaining seismic exploration acquisition data within the time period to be analyzed input by the user;

[0085] Step S120: using a preset sampling strategy to collect some data points of the seismic exploration data collected within the time period to be analyzed;

[0086] Step S130: Obtain the absolute values ​​of some data points for summing the absolute values ​​of the data in this channel.

[0087] Among them, by adopting sampling technology, some data points in the collected data are involved in the calculation, which can reduce the amount of data involved in the calculation, improve the calculation speed, and further improve the recognition speed and efficiency of the permuted single shot.

[0088] In an alternative embodiment, see Figure 7 The method for identifying out-of-order single shots in seismic exploration data may also include:

[0089] Step S500: Count the number of channels with zero neutralization value in the dropped arrangement single shot, as a basis for whether to use the data of the dropped arrangement single shot.

[0090] Among them, by counting the number of channels with zero neutral value in the arranged single shot, if the number of channels reaches the preset value, the data of this shot is seriously damaged, which will affect the accuracy of subsequent data processing (such as using seismic exploration data to establish a formation model). Therefore, this shot data can be omitted in subsequent data processing; if the number of channels does not reach the preset value, the data of this shot is slightly damaged, and the impact on the accuracy of subsequent processing is small, so the shot data can be omitted.

[0091] In order to enable those skilled in the art to better understand the present application, the following example illustrates the process of the method for identifying out-of-order single shots in seismic exploration data provided by the present invention:

[0092] Step 1: Decode the data and store them in sequence according to the file number.

[0093] Step 2: Determine the starting point of the sampling time period.

[0094] Step 3: From the starting point of the determined time period as the first sampling point, take 3 to 5 sample points continuously or at the same interval ( n is 3 or 5, m is the track number).

[0095] Step 4: Perform an absolute value operation on the obtained value to change the negative value in the data into a positive value

[0096] Step 5: Group the data using the file number as the first filter option and the channel number as the second filter option, and perform addition on the absolute value of each group of data. Then multiply the sum of each path

[0097] Step 6: Filter out the file number whose operation product value A is zero. This file number is the single shot of the dropped arrangement. Count the number of single shots in each dropped arrangement whose sum Ast is zero. This number is the number of single shots of the dropped arrangement.

[0098] Based on the same inventive concept, the embodiments of the present application also provide a device for identifying out-of-sequence single shots in seismic exploration data, which can be used to implement the method described in the above embodiments, as described in the following embodiments. Since the principle of solving the problem by the device for identifying out-of-sequence single shots in seismic exploration data is similar to that of the above methods, the implementation of the device for identifying out-of-sequence single shots in seismic exploration data can refer to the implementation of the above methods, and the repetitions will not be repeated. As used below, the terms "unit" or "module" can be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0099] Figure 8 1 is a block diagram of a device for identifying out-of-sequence single shots in seismic exploration data in an embodiment of the present invention. Figure 8 As shown, the device for identifying out-of-sequence single shots in seismic exploration data specifically includes: a data acquisition module 10 , a calculation module 20 and an out-of-sequence single shot identification module 30 .

[0100] The data acquisition module 10 acquires the absolute value of the seismic exploration acquisition data within the time period to be analyzed input by the user;

[0101] The calculation module 20 sums the absolute value of each channel of seismic exploration acquisition data;

[0102] The out-of-order single shot recognition module 30 recognizes out-of-order single shots according to the absolute value and value of each channel.

[0103] By adopting the above technical scheme, according to the sum of the absolute values ​​of the true values ​​of some time periods in a single shot, it is possible to quickly, effectively and accurately judge whether there is a drop-out phenomenon. This scheme is suitable for the single-shot quality control of seismic data acquisition in seismic data acquisition projects for oil exploration. It does not rely on other additional data, but directly uses existing data. It is simple and reliable, can reduce the labor intensity of personnel, prevent missed judgments and wrong judgments, and has good application prospects.

[0107] The product calculation unit calculates the product of the sum values ​​of each channel corresponding to a single shot;

[0108] The second recognition unit recognizes that the single shot with a product value of zero is a single shot with a dropped arrangement.

[0109] In an optional embodiment, the data acquisition module includes: a data acquisition unit, a sampling unit and an absolute value unit.

[0110] The data acquisition unit acquires the seismic exploration acquisition data within the time period to be analyzed input by the user;

[0111] The sampling unit uses a preset sampling strategy to collect some data points of the seismic exploration acquisition data within the time period to be analyzed;

[0112] The absolute value unit obtains the absolute values ​​of some data points and is used to sum the absolute values ​​of the data in this channel.

[0113] In an optional embodiment, the device for identifying out-of-sequence single shots in seismic exploration data further includes: a channel number counting module, which counts the number of channels with zero sum in the out-of-sequence single shots as a basis for whether to use the data of the out-of-sequence single shot.
