Anisotropy Parameters Analysis of Gas Hydrate Seismic Data Based on High Density Velocity Analysis
摘要
Abstract
During gas hydrate seismic data processing, there are still large amount of residual moveout in far offset data after high density velocity analysis based on hyperbola. It is considered by analysis that nonhyperbolic time difference is caused by anisotropic of igneous rock and transformation of vertical velocity. The paper can get rms nmo velocity by near offset seismic data, and obtain anisotropic parameters from scanning method and traveling time method. Then the paper applies it into anisotropy velocity analysis. The remaining NMO is eliminated, andimaging results have been improved significantly.关键词
