Geological Modeling Results Of Network Application Development

Currently, three-dimensional geological modeling, numerical simulation, seismic inversion of digital technology in the oil field reservoir large-scale applications, the detailed study of technology toward the reservoir scale, quantification, visualization, rapid development of the direction of the network, research each year growing, most of these results are stored in a number of dedicated distributed computer systems, the results could hardly be other users to share data, often there data corruption or loss of the case file.Geological modeling software, simulation software, expensive, a unit that is a set or two sets, but also the use of specialized graphics workstations, such as multi-node cluster computer equipment, research results can only be demonstrated in these special machines, So most of the on-site technical staff can not directly use the results of these studies. So, not only to resolve the outcome of the data storage problems, but also solve the on-site engineer visit the model results and interpretation of data, methods, through the internal LAN, using the ordinary PC (or laptop), see the published results, so as to make digital Reservoir technology more directly serve the oil field development.The establishment of fine reservoir description results library, use of modern information technology to libraries that meet certain achievement standards and norms, can retrieve, deliver and use information resources, the outcome of database application development system, deepen the reservoir of research results in practical use, is very necessary and urgent.Project will address three issues. First of all, to solve the geological modeling results of the storage and distribution. Centralized storage for achieving results, released, people can know where the outcome. Comes naturally think of disk storage, file, database, said release, think of Web site. Project was the use of these technologies we are familiar.The results of the storage solution, the results from the master data of the original structure and composition of the body to start. We note that modeling software, software, digital-analog data are organized by project, each project has a working directory, the working directory to the overall compressed into a file stored, you can use just extract the rehabilitation project original state, in this way for rapid reduction of the overall project, to facilitate tracking of the project, said the store as a whole in this way. Meanwhile, the results of data from different types of data, body composition, each type of import and export data can be used alone, it is important to as the interface with other software, data interface. Therefore, it is necessary to an outcome of the different types of data are stored, said stored this way for the classification. For example, Petrel modeling results can be divided into the model coordinate data, fault data, surface data structure, modeling attribute data, well trajectory data, Petrel software provides a classification of export and import data function. In addition, there will be an outcome other technical documentation, these documents also need to store. This, the modeling results to determine the content and storage ideas for logical database design and technology, designed the 16 data sheet, using a large relational database, ORACLE, in the form of data records stored in a dedicated database server, achieve secure storage and retrieval of data for the application of the results and lay a solid foundation.Results of the geological modeling data is loaded into the database, also need to be released after examination and verification for other technical personnel inquiries, download. This requires the development of a results-based management application platform, complete results data set, audit released, searching and retrieval, data download capabilities. Project uses the ASP.NET development technologies, refine the user permission settings, and improved user access logging, enhanced data security measures to address the ORACLE database BLOB type field of data storage and retrieval of technical difficulties.Finally, the development of the geological model based on the Windows platform, the outcome of three-dimensional display software. Petrel software to export the model data for the data source, through analysis of this data volume, master data structure, according to data in the grid coordinate system parameters through the three-dimensional visualization of the 3D rendering engine to create a model, and computer screen quickly and smoothly displayed. Software to solve the model quickly read large data volume, under the ordinary high-speed three-dimensional graphics display and three-dimensional model of illumination, rendering and other key technology to achieve the rotation, zoom, cut and print output function. Project successfully grasp the Petrel software, data output, the output of the VIP model data format developed as a three-dimensional modeling show that the data interface software to achieve a cost-effective method of modeling results show.The above, the R & D, is the key to success of the project. Around the focus of the project team, to strengthen technical research, rigorous project progress, timely completion of software development, testing and commissioning of the project as a whole, by identifying the problem rectification, the project passed the inspection, and put into practical application, taken a significant effect. Library to determine the outcome of the project design is a fine reservoir description results in database construction and application to make the greatest contribution, self-developed three-dimensional geological modeling results show that the software will show the technological innovation and solve problems on-site applications, the effectiveness of small investment large, the initial realization of the geological modeling, results distribution and display of application integration environment.Through this project, we have made a lot of knowledge. One of them, to pay attention to the construction of the overall technology environment. Multidisciplinary work fine reservoir of the software used, mostly abroad, and these are very advanced specialized software, but the overall technical environment, need to do a lot of basic work, in particular, to gain a clear understanding of each software The data structure and format of the results, open up the bridging of data between software systems, both to achieve data transfer between the software interface, to improve efficiency, but also for systems integrators and independent research and development to create favorable conditions.
