Automatic Velocity Model Building Technology

Abstract

The automatic velocity model building technology is a new velocity model building method researched all by ourselves, it had been supported by China Ministry of Geology and Mineral Resources and SinoPec petroleum corporation from 1992 to 2004. We have got Chinese Patent in 2004 after over ten years study. After that, we applied this technology successfully in several workareas of China with different geology conditions, such as foothill complex surface and subsurface structure in the southern part of Tianshan Mountain?carbonate platform edge in Tahe area and marine carbonate rock in southern China etc. This technology includes two main procedures: High Density CDR Velocity Analysis and Constrained Interval Velocity Inversion.
