Research And Implementation Of Mudlogging Guide Model Graphics

Experts use logging data of adjacent wells to analyze the block in target reservoir and build strata models in mudlogging guide model graphics. It is comprehensive graphics that can describe the relations between logging parameters and reservoir. Mudlogging guide model graphics reflects the drilling of well trajectory in the strata. According to the feedback information of drilling site, experts adjust the drill bit to control the extension of trajectory in the oil and gas layer. The implementation of the functional modules of guide model graphics is researched in this paper. In this paper, the functional modules are analyzed, designed and realized in view of program structure, execution time, maintainability and expansibility.Flexible operating system of graphic expression is researched in this paper by using Visual Studio.NET 2003, MFC framework and GDI+. In this paper, firstly, deficiencies and solutions are proposed after analysis of functional modules; then, system is designed using object-oriented method; process of system implementation is described in detail at last. The following aspects are investigated in this paper:(1)Functional modules of system are designed using object-oriented and reconstruction method. System is optimized in view of system maintainability, expansibility, execution time and legibility.(2)The method of building surrounding rock based on mudlogging curve data is: researched and designed in this paper. The acquisition, computation and storage of curve data and the process of building surrounding rock are described. The method, which using color mode to realize smooth transition of color, is researched and applied in the color filling module of surrounding rock.(3)The basic functions of graphics are realized, such as editing, saving and printing. Both the regular and professional operations are also realized. In completing graphics drawing function, the GDI+ technology is used; in implementing save and open function, the serialize method in MFC is used.In this paper, mudlogging guide model graphics build relatively accurate strata model on the basis of mudlogging curve data, it provides functions to meet specialized needs. Using method of object-oriented, the system designed has flexibility, maintainability and expansibility. The study in this paper laid the foundation for further development and function extensions. The system provides intuitive and effective guidance for drilling in practical use.
