在系统阐述应变位能理论的基础上, 从理论模型到实际资料的处理, 较详细地论述了位能转换的高分辨率处理功能；证明在选择合适空间步长的基础上, 位能转换可以在不损害资料信噪比的条件下, 提高地震资料的分辨率。简单地论述了应用应变位能转换提取横波信息, 为地震资料的油气检测提供一种辅助的手段, 从而证明位能转换是一行之有效的高分辨率地震处理方法, 并可为地震资料的解释提供有价值的横波信息。

We first introduce the theory of strain potential energy, then apply it to the processing of theoretical models and real data, and expound the function of potential energy transformation for high resolution processing. It proves that if suitable spatial step length is chosen, the transformation can im-prove seismic data resolution without damaging the signal-to-noise ratio. The strain potential energy transformation can also be used to extract S-wave information, which provides an auxiliary means for hydrocarbon detection using seismic data. These demonstrate that the potential energy transformation is an effective high-resolution seismic processing method and can provide valuable S-wave information for seis-mic data interpretation.
