The Development And Application Of Near Surface Model Software With High Accuracy

Complex surface area of the land surface is the result of problems faced by the seismic exploration a major problem in the restricted area complex surface seismic data accurate imaging, but also in the process of the acquisition parameters inspire great impact on selected issues.Liaohe region for the near-surface earthquake complex geological conditions, the first on the near-surface structure of the investigation process and related data, the data related to the integration into the work area for units in the database. In order to accurately determine the Low Deceleration Zone with changes of the surface structure on the basis of survey points to explain, using a high performance OpenGL 3D visualization technology, discrete data points to create a smooth surface; fitting in the three-dimensional surface , From the corresponding point of physical corresponding data; establish a rational model of the surface structure and realize the wild with low Deceleration Zone information calculated to import all the automation and data visualization, developed a suitable structure of the surface area of Liaohe model of software.On the basis of the model, designed to increase the field of automatic use of the design parameters of depth features, the computer automatically exploration of the wild gun point work plan, ultimately improve the work area of production automation, improved seismic exploration field of construction quality and efficiency.
