Research On Two-dimension Visualization Integration Of A Qt Based Reservoir Modeling System

In the process of oil and gas filed development, the geological map can be comprehensive, true representation of the geological reservoir modeling, and various properties of the reservoir. This geological map may be used to express various geological features, such as stratum, sedimentation, structures and reservoirs, and which can understanding the concentration of oil and gas, and determine the appropriate direction for exploration, development well location and development plans for oil and gas. Among them, in the two-dimensional structural map, the contour map is used the most widely as a geological map. The contour algorithm has been30years of development history, with the development of domestic oil and gas reservoir modeling and reservoir description technology, this algorithm is still research. Drawing the histogram and scatter, and which is an integral part the description of reservoir modeling. Compared to the expensive foreign modeling software modeling, development with its own intellectual property rights has a great practical significance. This article’s Innovation and research are as follows:Firstly, Qt class library is a cross-platform object-oriented C++class library. This class library contains three parts:control, framework and tools, and which is provide widely support for object-oriented system. The graphical user interface based on Qt framework, using the various existing modeling, and which have constructed the two dimension visualization reservoir modeling system.Secondly, in order to perfect the function of two dimensional visualization module, the article study two types of software integration, and which is applied in the two dimensional visualization integration:data integration and application integration. Depart from the two different type of integration, Intensively study original module function, such as the contour drawing technique, layer and color technique, and bring forward the data integration, paper and function integration as a whole of system integration solutions. It is integrate the function of original, scattered modules, build a new interface using Qt, and which is to achieve software integration.Thirdly, the article studies histogram, scatter rendering algorithm, and have a detail discussion about based on the interpolation algorithm of rectangular grid and triangle grid map.Fourthly, through measured by field data analysis and system design and operation has proved the integrated two-dimensional visualization module which is accurate draw the geological map and object-oriented system has good real-time, interaction, interactive, and operational flexibility, easy to maintain and extend.
