Research And Implementation On 2D Visualization Technology For Oil Fieldgeological Data

The two dimensional visualization technologies of oil field geological datas is mainly based on visualization method s of mapping out geological datas.In the visual graphics, we can catch sight of direct relationships or implicit relationship s of these two dimensional geological datas. So this research has great significance to the next steps of the oil field mining and the management of the existing datas.In this paper, we will use the two dimensional geological datas of the first oil production factory of Daqing O ilfield as the research object and focus on the study of Shape surface data visualization mapping, taking sedimentary facies data visualization as an example. We study the application of Delaunay triangulation technique in two dimensional data plane mapping and improve the accuracy and speed of the visualization by ameliorating the existing algorithms. First, search for all datas to establish the convex hull According to the sedimentary facies, which ensure that the same sedimentary facies is in one convex hull. Secondly, insert the discrete data points into the given convex one by one. At last, use the technology of convex combination technique to combine different other convex hull as a large triangular mesh. Besides, in addition to some commonly used visual interaction techniques, we also use same other human computer interaction technology on mapping results, with Focus+ Context as the main method. According to the relationship between sedimentary facies data and location data, we make same improvements on Focus+ Context, which makes the system more convenient to use. In the end, we make a system according to the two algorithms named “Dynamic analysis platform for basic geological work and automatic customization”, which farther proves the practicability of the algorithm.The research contenting of this paper has been applied in the scientific research project of the first oil production factory of Daqing O ilfield. The actual application effect show that the visualization mapping has fast speed and high precision as well as that it?s interactive visualization method is convenient, fast, and high efficiency which is convenient for the user to use.
