| 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. 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. 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. 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. Is the core of the study.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.To achieve imaging logging data management and distribution network, log data is often the binary file formats must decode analysis.Liaohe Oil Field for data logging AscII common code, PE716, XTF file format for analysis and program custom solutions for storage.XTF file is ECLIPS5700 logging system to generate real-time logging of data files, which contain a great amount of information. It consists of pieces of the title and most of the 2 pieces of data, the smallest unit is composed of records, each record length of 4096 bytes, including the title of the piece is usually 8 records, the data block that contains the number of records from the curve To set the depth range, XTF file to allow the coexistence of the different characteristics of the curve, for example, the initial depth of the curve, the end of the depth of the sample rate can be different, and so on. XTF title of the document file name records for the block, the oil companies were, well, well site and the information curve characteristics (such as the curve, be a few curves, the curves dimension, the depth of the start, the end of the depth of the sampling rate), and so on Information. The title of the document XTF block after block followed, the XTF data blocks used to store data files. Each curve of the data storage are two parts, namely, the first record of the curve (4096 bytes) of data and records (according to their length of each curve of the start and end of the depth and depth to determine).716 logging data formats commonly used data from one record format. The oil field as a result of a variety of reasons for the title of the 716 block of information with varying degrees of adjustment and the additions and deletions, PC computers and SUN workstations on the floating-point data stored in the body in the storage format is different. 716 applications, particularly in the PC machine SUN workstations and data exchange between the need to convert the data format for reconciliation.Logging for data management in storage requirements, in addition to the above data storage format, but also need to look at the structure of the middle layer, the interface is reserved for the system to meet all the logging data storage format, which Web log data management system provides a viable reference to the program.As a result, de-system have three functions:(1) data files through the de-systems, direct storage.(2) data files through the system, de-, middle-generated documents, external to the system.(3) external data files will have a document in the middle layer, through the de-storage system.Through the above strategy and program development, the completion of the logging data de-Web system, and put into application. In the application process is also found to be more problems, the need for further improvement. 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. |
