摘要：
Seismic resolution has been leading the development 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 geological 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. © 2022, Editorial Department OIL GEOPHYSICAL PROSPECTING.
