| 摘 要： | 本文介绍了Kirchhoff积分法叠前深度偏移和波动方程叠前深度偏移两种偏移方法,并通过对Marmousi数据模型和实际数据资料处理,对比叠前深度偏移成像与叠后时间偏移成像和常规叠加剖面的应用效果。实际结果表明：对于速度横向变化剧烈的复杂地质体,叠前深度偏移成像精度更高,适合于城市活动断层的高精度探测。

| Abstract: | The paper introduces two migration methods:Kirchhoff depth migration and wave equation prestack depth migration,and compares the imaging result of prestack depth migration with conventional stacked profile and post-stack time migration profile by processing the data model of the Marmousi and the actual data.The result shows that prestack depth migration is more accurate for complex structure imaging in media of strong laterally varying velocity,and suitable for the more accurate detection of urban active fa... |
