| The technolodge of geophysical logging including widen scientific aera, and many high techniques were used, so the geophysical logging information has abundance and complexity characteristics. This made geophysical logging information should use complete and effective data models for describetion and defination.In accordance with object-oriented methods and techniques, the establishment of a logging-oriented data model and the geological target and other parameters of the base class was introduced in details, such as the calculation of reservoir properties (porosity and permeability), oil-bearing potential, oil saturation, and the other geological parameters. A new target model for the geological conditions of the logging data processing system was established. And we change the traditional calculation oriented logging analysis techniques to the geologicaltarget oriented logging analysis techniques. The complex geological conditions logging analysis system were accomplished. This logging data processing system is a support to the core beliefs of " Geophysical Logging is Technique and Art". Therefore, the new logging system is more congruous to the values of actual production well.Goal oriented geological targets of logging data processing for research and development process, defined the data structure classes and geological targets base class, and on this basis, designed and implemented of well logging curve correction, logging data analysis some software, for the first time in the application of "object-oriented (Object Oriented, OO)" logging technology combined with the technical key issues, made a series of technological achievements.The system to LPS data bus as a link in order to rely on the database, the connection field logging data decompile, logging curve correction, goal-oriented geological log interpretation, multiterm auxiliary tools, graphic screen display and under the management of common CGM graphics and other software modules. Goal-oriented geological logging data processing system compared with conventional logging interpretation software, has its distinct characteristics, namely, the definition and design of the system used by all data types, through the logging subsystem calibration curve of its be calibrated and standardized so that a variety of applications to meet the different needs for data access; Second, it has standardized and object-oriented design ideas, a variety of typical geological targets on the base class has been designed so that a variety of the analysis and evaluation of geological parameters, the calculation for the shift from the goal-oriented.The main research work and contributions are as follows:1.The determing rules of logging data sources, category definitions and data models were studied;2.The basic principles and methods of logging data processing were studied, the formation porosity, permeability and saturation of the main geological parameters, such as the classification and definitions,were completed;3.The base class of the logging data model for geological targets were definited and implemented;4.System requirement analysis, the system design and the detailed design were described in detail;5.The log correction, the standardization, and the partial oil well logging analyzes software's code were achieved;6.The log correction, conventional logging processing function modules testing, and trial production were completed. The experimental data validate the correctness and effectiveness of the design.The research results have been used in the shengli logging company's actual producte applications. Compaired with other geological parameters calculate system, the results are completely matched. Through a trial by the oil industry oil flow, it achieved a high economic efficiency. The research results also will be incorporated into "logging analysts scientific work platform". |
