| Abstract: | First in this paper,the authors investigate the effectiveness for using the seismic reflection tomography technique to estimate the lateral variation of seismic velocity on the basis of numerical simulation,then, the technique is applied to the seismic data from the Bohai Oil Field. Based on the seismic reflection data,it is proposed that the reflection ray paths are distributed approximately vertically. As a result,it is suitable to use the reflection tomographyic technique to determine the lateral velocity variation in the target layer. |
