深度成像和速度各向异性是目前地球物理勘探与开发最活跃的两个领域。适当考虑速度各向异性就能更全面地实现深度成像的潜在优势。深度成像依赖于速度模型的准确度。如果存在各向异性,而在速度模型的建立和偏移中却没有考虑到,那么最终成像就会出现错位或假构造,加大出现干井的 Depth imaging and velocity anisotropy are two of the most active areas for geophysical prospecting and development. With the proper consideration of velocity anisotropy, the potential advantages of deep imaging can be realized more fully. Depth imaging depends on the accuracy of the velocity model. If there is anisotropy, which is not accounted for in the modeling and migration of the velocity model, then the final image will appear dislocated or fictitious, increase the occurrence of dry wells
