摘要
以数值模拟方法为基础，考察了反射地震层析成像技术对油气储层波速横向检测的效果，然后用渤海油田的地震资料进行了实用试验．对数值模拟结果和实际数据的试验结果进行了分析与评价，认为油气勘探中的反射地震资料具有地震射线近似垂直分布的特点，适合用反射地震层析成像技术进行目标层横向非均匀性检测．
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.
