Abstract

Способ и система для формирования изображений представляющей интерес подземной области. В общем случае одно осуществление настоящего изобретения включает в себя задание граничных условий с использованием сейсмических данных и начальных условий, которые включают в себя возбуждение из мест нахождения источника в модели среды. Затем волновые поля источника распространяют в прямом направлении через модель среды до максимального времени и сохраняют во множестве контрольных точек, редко во времени, и также сохраняют соответствующие граничные значения волновых полей источника на каждом временном шаге. Кроме того, волновые поля источника распространяют в обратном направлении через модель среды, начиная с максимального времени, используя множество контрольных точек, при доступности, и сохраненные граничные значения на каждом временном шаге. Совместно, начиная с максимального времени, через модель среды распространяют в обратном направлении волновые поля на приемнике. Условия построения изображения на выбранных временных шагах накладывают на распространяемые в обратном направлении волновые поля источника и волновые поля на приемнике, и эти волновые поля используют для формирования изображений, относящихся к подземной области.
