摘要

SU气田地下地质情况复杂，有效储集砂体分布非均质性强，常规方法对含气有利区的预测符合率低，不能满足开发的需要。利用保真处理的三维地震数据体，进行叠前及叠后地震资料的地震属性、波形分类、频谱分解处理和三维可视化、AVO远近道对比研究，并综合上述研究成果进行岩性与含气砂体的横向预测，较好地解决了有效储层分布及含气有利区块分布的非均质性问题，同时指出了研究过程中使用地震属性时应注意的问题。

Abstract

SU gas field has complex geology, the reservoir in the field was featured with strong heterogeneity. Previously, part of research could not meet requirement for product. In this paper, some seismic attributes that include seismic waveform classification, spectral decomposition, 3D visual, and AVO characteristics were extracted from pre-stack and post-stack seismic data that include far, near offset and full offset stacked seismic data. By integrating above information, the question of heterogeneity was solved to a certain extent and the reservoir and gas-bearing were predicated. At last, the pitfalls which occur in the application of seismic attribute are summarized.

Key words： SU gas field; Seismic attribute; Wave shape; Far and near offset trace stacked profile; Seismic attribute pitfall.
