通过建立合适的深-时转换速度模型，将井间地震资料从深度域转换到时间域。

An appropriate velocity model for depth-time conversion was constructed. The data can be converted from depth domain to time domain.

利用CDP道集，可以直接获得共中心点叠加时间剖面或视深度剖面，由此可转换为法向深度剖面。

By using the CDP gather, common-mid-point stacked time section or apparent depth section can directly be obtained, which can be converted into normal depth section.
