Design And Implementation Of The Micro-seismic Visualization System

Micro-seismic mostly generated by underground stress field changes caused by hydraulic fracturing or conventional water injection, gas injection, and many other petroleum engineering jobs. It is an important basis for the analysis of distribution toward of oil and gas reservoirs. The micro-seismic monitoring is a technic which realise by using visualization techniques for the micro-seismic signals collected to fracture imaging for the purpose of monitoring the reservoir fluid movement. With increasing levels of computer hardware and software, scientific visualization technology position in seismic data processing and interpretation work has become increasingly prominent, especially in seismic data visualization technology has become the forefront of technology geological studies, seismic data processing system is currently a key core, therefore, to design a three-dimensional image of seismic data systems are also extremely urgent. The original image data to be displayed directly in this way is more visually intuitive, and can be so revealing hidden data inside the law, to provide accurate, reliable and intuitive handling evidence for the treatment staff.Firstly, through the oil exploration industry, the most common seismic data format- three-dimensional seismic data(SEGY format) for analysis, SEGY correctly parse out the format of the data file header and data volume, and the ability to correctly read the data of each field for three-dimensional seismic data provides the basis for drawing an image system.Secondly, the use of three-dimensional seismic data parsed out, depending on the read data reading strategies, drawing on the body in all directions profile data, which is to ensure the quality of the image, the drawing process using bilinear interpolation algorithm, and then use OpenGL texture mapping technique, the image is mapped to the three-dimensional scene to achieve a three-dimensional seismic data display data field as a whole, slice each direction display.Finally, the design of some of the interactive features of the three-dimensional imaging systems, including three-dimensional coordinate system transformation scenes, rotate, zoom, color labels, image transparency settings.
