[0002] Currently, major oil companies are developing cloud-native applications. The developed applications are not located in traditional data centers, but in the cloud, so that they can be accessed through the Web when users operate.

[0003] At present, GeoEast software is accessed based on C / S structure. Software deployment, upgrade and maintenance need to be operated on the client. In order to support data display based on Web access, it is necessary to establish an access system based on network services and a graphic engine and data display scene of typical seismic exploration data to perform display service. In the process of display service, it is necessary to form a graphic display capability of typical seismic exploration data based on network services based on the seismic exploration data on GeoEast-iEco, and form a graphic service development environment that can support the development and integration of GeoEast data through Web graphic service modules, complete the development of graphic browsing functions and graphic interface functions, and the development of business scenarios such as network maps, single well maps, profile maps, and structural maps.

[0004] The current problems faced by Web-based display services are: 1. The volume of seismic exploration data is large, and Web-based access has high requirements for loading speed and operation fluency, which requires reasonable structural design and performance optimization; 2.

[0054] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0055] Example 1

[0056] like Figure 1 As shown, this embodiment is a Web visualization method for oil and gas exploration, including the following steps performed in sequence:

[0057] S1. Create a Web data interface access connection for GeoEast-iEco according to business scenario requirements to obtain seismic exploration data on GeoEast-iEco.

[0058] In this embodiment, five business scenario requirements can be realized, including plane map, seismic profile, single well, multiple wells and three-dimensional visualization. The acquired seismic exploration data is the massive oil and gas seismic exploration data on GeoEast-iEco, including work area, layer and fault data.

[0059] S2. Classify the data obtained in step S1 step by step according to business requirements, encapsulate the data, and integrate them into a data tree corresponding to the business requirements.

[0060] The content in the data tree includes the displayed data item type and the icon of each data node. When integrating into a data tree, you can generate a file template by configuring an XML format file and save the file template. In this way, the data tree can be dynamically managed according to the corresponding file template configured according to business needs.

[0061] S3. Select data in the data tree and use the graphics engine to generate a graphic element information file according to business scenario requirements.

[0062] The graphics engine uses a C++ interface, and its dynamic library includes header files and library files, which can perform data mapping, graphics browsing and graphics interaction functions based on the graphics engine.

[0063] S4. Parse the graphic element information file to generate graphic element information read by Js.

[0064] S5. Update the display page synchronously and asynchronously according to the image metadata.

[0065] In order to achieve a balance between user experience and performance, when updating the display page, JavaScript is used to call the development interface to achieve synchronous updates; AJAX technology is used to call the XMLHttpRequest function to achieve asynchronous updates.

[0066] In summary, the method used in this embodiment can obtain seismic exploration data deployed on GeoEast-iEco, and provide efficient display service support on the Web according to business scenario requirements. Mainstream browsers support access and have strong versatility.

[0067] Example 2

[0068] like Figure 2 and Figure 3 As shown, this embodiment is a Web visualization framework for oil and gas exploration. This embodiment is used to implement Example 1. The entire framework is developed using a B / S architecture. The project supports installation and deployment on Linux and Windows platforms. This embodiment includes: a front-end module containing a display page, a back-end module, and a storage module.

[0069] On the one hand, the front-end module sends business scenario requirements to the back-end module based on user needs; on the other hand, it receives the graphic element information file transmitted by the back-end module, generates graphic element data after parsing, and updates the display page synchronously and asynchronously based on the graphic element data.

[0070] The front-end module is built using HTML, CSS and JavaScript front-end languages. HTML completes the overall page display, CSS performs page style layout, and JavaScript can realize front-end and back-end data transmission, network communication, and the application of triggering events in the page. Based on different business scenarios, API interfaces are called to realize Web page data mapping and application interaction.

[0071] On the one hand, the back-end module receives and responds to the business scenario requirements transmitted by the front-end module and sends data call signals to the storage module; on the other hand, it receives the GeoEast-iEco seismic exploration data sent by the storage module, then classifies and packages the seismic exploration data, generates a data tree, uses a graphics engine to generate a graphic element information file for the data tree, and transmits the graphic element information file to the front-end module.

[0072] The storage module receives the data call signal transmitted by the back-end module and transmits the corresponding GeoEast-iEco seismic exploration data to the back-end module.

[0073] The display interface in the front-end module includes six functional components: data tree, toolbar, eagle eye navigation, layer tree, menu and property window. Each functional component corresponds to the business scenario required by the user. When developing the front-end module, the code is divided according to the component modules. For example, the data tree file under modules lists the basic data tree template component and five data tree components with different implemented business scenarios.

[0074] Functional components can be added or deleted according to the addition and reduction of business scenarios. For example, when adding a new business scenario, you can develop the components required for the new business scenario based on the code structure and deployment method of the existing components, select the components to be displayed in the component management js file, and arrange the components in the html file.

[0075] Example 3

[0076] like Figure 4 As shown, this embodiment is a framework building method for implementing Example 2. The operating system version used in this embodiment is an offline environment of CentOS7 (Linux). This embodiment includes the following steps performed in sequence:

[0077] A1. Obtain the C#-based backend project file and configure the backend C# development environment.

[0078] Specifically, step A1 includes the following steps performed in sequence:

[0079] A11. Get the C#-based backend project file. According to the operating system version, download and decompress the corresponding version of the .net 6.0 SDK tool package to the newly created dotnet tool folder.

[0080] A12. Configure the environment variables of the dotnet tool folder.

[0081] When configuring the environment variables of the dotnet tool folder, you need to add the path of the folder where the SDK tool package is located to the PATH variable in the .cshrc file, and use the source command to apply the environment configuration. It should be noted that the dotnet command needs to be used normally in the command line during the configuration process.

[0082] A13. Configure the NuGet library.

[0083] NuGet is a package management tool for the .net platform, which provides a series of clients for generating, uploading and using packages. When there is an external network connection, you can configure the online NuGet package source and use the corresponding commands to automatically configure the required package source for the C# project; in an offline environment, you need to pre-download the package source in a wired environment and import it, and then manually configure the NuGet.Config configuration file to set the package source folder path to the target path.

[0084] A2. In the root directory of the backend project folder, use the dotnet restore command to compile and complete the release of the classification encapsulation and graphics engine functions in the backend module.

[0085] When compiling and publishing the classification encapsulation function, enter the folder of the backend project and use the dotnetpublish -c Release -r linux-x64 --self-contained true -o ~ / webapp command to compile, where ~ / webapp is the target path of the application.

[0086] When compiling and publishing the graphics engine function, enter the folder of the backend project and use the dotnetpublish -c Release -r linux-x64 --self-contained true -o ~ / webapp / GDFMapServer command to compile, where ~ / webapp / GDFMapServer is the target path of the application.

[0087] In the subsequent function development process, you can start the program for debugging through the dotnet run and dotnet watch commands.

[0088] A3. Get the JavaScript-based front-end project file and copy the entire front-end project file to the wwwroot folder under the application root directory.

[0089] A4. Configure the drawing dynamic library and the startup script start.sh.

[0090] The configuration method of the drawing dynamic library is: unzip the drawing dynamic library compressed package in the source code to the RefLibrary folder under the root directory of the application. The configuration method of the startup script start.sh is: add the drawing dynamic library environment variable in the script, and add the path of the drawing dynamic library to the LD_LIBRARY_PATH environment variable.

[0091] A5. Check and modify the service address and port number in the file.

[0092] After the proofreading and modification in step A5, users in the same network environment can access and use the display service through the service address and port number.
