Research And Implementation Of Imaging Well Logging System Based On Web

Imaging logging is the world's most advanced logging techniques. Its internal format has not been released, the interpretation of the results of the use of playback of the main Atlas eXpress, Geoframe package, and so on, and the high cost of the package, and can only be used on workstations, so the application of scientific researchers have had a great Difficulties, and only a small number of domestic software will be able to convert it to use in-house format, and are dedicated software, and can not be present Liaohe exploration database integration, there was an urgent need to develop imaging logging data network management and distribution systems, completion of the exploration database on the imaging test Well data conversion, data loading, network management, network information, such as Web browsing features. The most important is the realization of Web graphics, completed by the management of imaging data display to users. It can provide visual geology, reservoir and accurate information in a complex formation evaluation logging plays an important role. How to become a centralized management of data needed to solve the problem, and the establishment of a complete set of log data into a database feasible and widely used. As a result, the information database based on the logging of the Web browser means logging image, has also become essential. Imaging logging image processing technology to be two-dimensional images of the wall or a hole around the depth of exploration within the three-dimensional images. Logging imaging test images of rock cracks in the rock composition and a more intuitive, and so on. But not the original image after image processing, to reflect the characteristics of the terrain was not obvious, after dealing with dynamic histogram image brightness of the background, logging more appropriate to observe the corresponding changes in the value of the lithology and comparative analysis, usually well above the rate of resistance The big change, it is necessary to understand the details of the underlying information, standardization of dynamic images due to a long window to deal with long and can not meet the requirements of geological analysis. Dynamic contrast-enhanced images in a smaller set by the user to the sliding window on re-color scale, the dynamic contrast-enhanced images for the increase of holes on the special characteristics of the region's definition, but local long-short window to make the image appear higher level, As well as the thickness of more than window-long section of the vertical changes in the obscure. Through a large number of comprehensive data logging, and detailed analysis, as well as experts on the basis of adequate communication, data logging oil field is divided into information, information areas, well static, dynamic logging, logging data, measured Well curve, logging data tables, well-related documents, the parameters of several types of card information. Modern office and scientific management of personal need to work together with each other on the one hand, the need for information exchange and information sharing in order to be able to make full use of resources and improve efficiency; on the other hand, as well as between the business sector between superiors and their subordinates are Need for regular exchange of information.With the large number of data logging oil fields have a need to establish a complete database of log data. In the establishment of a network server for storage and management of the original logging data and results (including the oil fields, oil well logging and basic data information, log file information, as well as related studies, the report explained, to deal with parameters, multi-media Reporting, graphics files, etc.) standards, security, logging and efficient database system and improve relevant, flexible data dictionary. The amount of information which is the biggest curve of the original data, not only for the data storage, users also need the client graphics. Since the logging data formats and a large variety of types of curves how to save data storage, and the system can cope with the future of the format change.The current domestic Forward logging software, such as imaging with the Web log data management and effective combination of Web-based graphics. Based on the Liaohe logging data management to achieve one of the Web mapping system.At present, most of the Web mapping system used by most of the focus on strategies to address data transmission. Logging data, in particular the imaging data logging, data sample density, the amount of data, each of the general well as 600MB of data about the most up to 2GB, so a large amount of data from all server-side delivery to the client can not be achieved The need for special data strategy, commonly used strategy is to reduce sub-transmission by the client application based on the user's point to the need to put the server send the request, the server is based on the request of organized into packets, and then on the packets Compressed transfer, the client to receive compressed data packets, to extract further graphics display.In this paper, in addition to the methods used to achieve network mapping, focused on using technology to build Web Service mapping Web server, will complete the mapping request to the server, send pictures to the client the way for large Web mapping data to provide a reference to the optimization program.Applet because Java is a platform for expansion, the establishment of the Applet with the establishment of the web application interface, you can reuse existing Java components, embedded in the browser Applet can be as stand-alone applications to achieve the same functionality and reflect the User interface, so, Web mapping system used to prepare Applet client.For network users, according to the current screen to read some of the data, the speed of the network is permitted. Applet and Servlet interaction can be achieved with the reading of the data transmission. Applet and Servlet four interactively, using two, HTTP streaming text used to transmit data, HTTP stream for object serialization to pass the object of these objects contain all the client needed.For users outside the network, network speed transmission does not allow too much data or documents, used to achieve the Hessian mapping Web server. Hessian is a heterogeneous web service, the agreement because it is not SOAP, but provided its own binary protocol. Hessian of the servlet to provide a server-side base class, client-side access to a service interface (that is, stub) after calling the above methods, stub to marshal after the method call through HTTP reached server, server use reflection to call methods of service. Through this way, the graphics will be available to the graphics server, and the client only after the show draw pictures, make such a poor speed Internet users can quickly browse the results of the drawing.Modern office and scientific management of personal need to work together with each other on the one hand, the need for information exchange and information sharing in order to be able to make full use of resources and improve efficiency; on the other hand, as well as between the business sector between superiors and their subordinates are Need for regular exchange of information.Both within the network client or outside the network's Web server graphics program, the existence of large amounts of data, how big the data to improve the speed of graphics, it is necessary to resolve the issue. As the JVM memory size restrictions, making Java Applet will be very difficult to put the data in memory, the memory mapping technique that is used to solve the above problems, and increased the speed of reading. The network's client, could redraw the regional map to increase the speed of the program, the foreign network of Web mapping server, you can respond to each user's screen image, to improve the efficiency of the response to the user.Through the above strategy and program formulation and adoption of further study of the electric sound imaging, full-wave, the magnetic spectrum, such as a total shock of the algorithm after the completion of the mapping Web log, and put into application. In the application process is also found to be more problems, the need for further improvement. Research projects, logging data to the clutter of projects for a number of additional workload. Data provided by the logging, processing of raw data and the results of the mixed data, graphics parameters useful documents and have not used the drawing parameters are mixed with paper, there are parameters to deal with useless data files. There are even a number of data files can not be used. The data files clutter affects the progress of the work, and non-standardized data have a direct impact on the quality of the data release. As a result, there is a need for standardization of data, at the same time to develop viable standards, standardized data submitted to the work.Java Applet based on the characteristics of its own memory serious enough to deal with common logging large amounts of data information, using memory-mapped, local as well as local refresh redraw the way to complete the network model within and outside the network mode Fast mapping function. Electric and acoustic imaging, full-wave,Graphics realization of the Web server. Learning Web Service technology, skilled in the framework of Hessian, the Hessian go into details about the realization of the principle, and Web graphics system in the proper use of the framework, the completion of the mapping Web server functionality prepared to make to meet the needs of Internet users.Although the project has been completed, but as a result of the project involves complex technical comparison, the use of the process, there will inevitably be some problems need to constantly improve the software. More importantly, as the application level, expand the scope of application, the software needed to further complement and strengthen, to design a higher level of network distribution system.
