逆时偏移在辽河外围复杂构造资料处理中的应用

Application of reverse time migration in data processing of complex structures around Liaohe River

随着勘探目标越来越复杂,对地震成像要求越来越高,逆时偏移方法相对Kirchhoff偏移方法和单程波偏移方法,具有原理简单、成像精确且无倾角限制、适应任意复杂速度模型等诸多优点,越来越多的在生产中得到应用。

Seismic imaging has met higher requirements when the exploration targets become more complex. Reverse time migration method is simple in principle,the imaging is precise without obliquity limitation,and is adapt to any complex velocity models compared with Kirchhoff offset and one-way wave migration,therefore it is widely used in production.
