如何制定高分辨率地震勘探中的技术指标

在我国，开展高分辨率地震勘已有十多年了，但以往各单位对高分辨率勘探所能达到的技术指标的提法不很一致，很难进行统一的对比与评价。本文在较系统地讨论了地震勘探中各种频谱参数的基础上，对比分析了原始地震记录与地震剖面上反射层频率的高低，提出了用频扫记录上反射层所能达到的实际“视率”来衡量地震资料分辨率高低的建议。

How to make the technical index for the high-resolution seismic exploration.

High resolution seismic exploration has already developed for more than ten years in China. But in the past, the units were not in agreement with the formulation of the technical index available for the high resolution seismic exploration, so the correlation and evaluation were difficult to make unitively. This paper correlates and analyzes the reflection frequency range of the field seismic record and seismic section on the basis of systematically discussing all kinds of frequency parameters in the seismic exploration, and makes a suggestion that the seismic data resolution should be measured using the actual visual resolution obtainable form the reflection on the frequency scan records.
