摘　　要：纯东地区勘探目的层沙四下亚段红层地震资料品质差,难以满足精细构造解释的需要。地震资料特殊处理有利于改善地震资料品质,采用小波分频特殊处理技术,取得了较好的效果。在地震资料品质较差地区,通过区域应力特征分析,根据上下层位和基底形态,以及周边品质较好地震资料类比和推断,应用局部应力分析等方法建立相应的构造解释模式,来指导研究区目的层的构造解释。The seismic data from the target of Sha 4 are of poor quality in Chundong region, which impedes fine structural interpretation to be carried out In this paper, we adopted frequency-division processing to improve the data quality. In data interpretation, structural patterns were established according to regional stress analysis, the geometries of overlying/underlying formation and basement, and high quality seismic data. The patterns were then used to guide seismic data interpretation, especially for data of poor quality.
