摘要
在当前的地震勘探中，进一步加强对ｖｐ／ｖｓ、σ以及纵、横波分辨率比较的研究，对提高地震勘探精度，划分地质薄层与小地质体及小断块以及联合利用纵横波进行油气预测、岩性预测和查明小地质体储油状况具有重要意义。作者在前人研究的基础上，提出用地震波波长来表述纵横波分辨率及其关系，以求对纵横波分辨率有更清楚的认识与更充分的利用。
It is of great importance to further study the v p/ v s and σ and the comparison of the relation of the discernibility of p wave and s wave to improve the precision of seismic exploration, lay geologic thin layers, mark out small geology units and small faults. In this paper, v p/ v s and σ are acquired by using the time sections of P and S waves in the same plane, and the wave length of seismic waves is used to represent the discernibility of P and S waves and their relation so that they can be better used.
