吸收衰减对地震分辨率的影响

Influence of attenuation by absorption on seismic resolution.

大地吸收衰减作用是获得中深层高分辨率地震资料的主要障碍,因此研究一个地区的地层吸收衰减是进行高分辨率地震勘探的基础。以往地质模型正演分析技术主要用在观测系统设计上,本文将该技术推广应用到吸收衰减对深层分辨率的影响研究上,能更好地从理论上指导深层地震数据的采集和处理。

The attenuation by ground absorption is major obstacle for acquiring high resolution in mid-deep depth, so that study on attenuation by strata absorption in an area is basis of high-resolution seismic exploration. The former forward simulation of geologic model mainly aimed at the design of geometry, the paper popularized the technique into apply to influence of attenuation by absorption on deep resolution, which can better guide acquisition and processing of deep seismic data theoretically.
