| 摘 要： | 地震资料高分辨率处理技术主要是提高地震资料分辨地质体的能力，利用该数据进行解释和属性分析，在寻找隐蔽油气藏中起到重要的作用。本文针对高分辨率处理过程中噪音衰减、保真处理，频率拓宽方面进行研究，并在江苏洪泽地区盐矿地震勘探中应用取得良好效果。最终处理资料具有较高的分辨率，主频达80Hz，频宽20Hz～160Hz，其波阻抗反演剖面较好识别了该区盐矿的分布范围，厚度，为盐矿开发提供了科学的依据。

| Abstract: | High-resolution processing technology of seismic data can enhance the ability to distinguish geological bodies from seismic data, which plays an important role in hidden oil pool exploration and development. This paper performed a study on noise-attenuation, perfect fidelity processing and frequency-widening during high resolution processing, which was applied successfully in salt mine exploration of the Hongze area of Jiangsu province. The final processed data has high resolution, with main frequency being 80Hz and frequency width 20- 160Hz. The inverse section of wave impedance can be well used to tell the thickness and distribution of salt mine, serving as scientific basis for development of salt mine. |
