摘要
Bai-58 well of Baiquan area on the northwestern margin of Junggar basin is a complex fault-block area. In order to obtain the fine structure of sedimentary in the study area, the authors use various processing technologies such as pre-stack multi-domian noise attenuation and non-linear pre-stack time migration for doing high-resolution 3D seismic reflection data on base of the analysis of the raw seismic data and problems. The results reveal the development characteristics, spatial distribution patterns and the relationship of surface composition of Bai-Wu fault. According to the section showing the strata thickness, structural feature,and characteristics of the seismic reflection wave group, the study area is divided into the three major structural layers.
