地震分辨率思考与高分辨率勘探对策

地震分辨率问题一直引领着地震勘探技术的发展方向。在分析地震分辨率与信噪比关系基础上，明确了地震资料品质定量表征方法。在剖析地震资料解释极限基础上，定义了地震地质解释能力作为地震资料实际可解释地质细节的能力。厘定了高分辨率地震勘探和高精度地震勘探的概念及差异。分析了影响地震分辨率的各种因素，并将其划分为地震子波内在因素和外在(地震、地质)因素两类。从地震采集、处理和解释三个方面阐述了提高分辨率的技术途径和未来发展方向。

Thought about seismic resolution and countermea-sures of high-resolution seismic exploration

Seismic resolution has been leading the develo-pment of seismic exploration technology. On the basis of analyzing the relationship between seismic resolution and signal-to-noise ratio, this paper clarifies the quantitative method to characterize seismic data quality. After analyzing the seismic data interpretation limit, it defines seismic geologi-cal interpretability as the ability of seismic data to interpret geological details. The concepts and differences between high-resolution and high-precision seismic exploration are defined. Additionally, the factors affecting seismic resolution are analyzed and divided into internal factors of seismic wavelet and external factors of seismic exploration method and geological conditions. The technical approaches to improve the resolution and the future development direction are described from three aspects of seismic acquisition, processing, and interpretation.
