摘要
To improve seismic survey,as one of the State Projects of Strategic Area Survey and Evaluation for Oil and Gas Resources, a wide-line seismic study has been conducted in complex mountainous areas in Hero Ridge area in Qaidam Basin. Based on difficulties of seismic exploration and the previous seismic projects in the area, the authors propose some new strategies for this study. Then, the authors describe a series of techniques of the wide-line seismic including acquisition and processing for the area from field tests. The results show that wide-line seismic exploration is applicable and effective for the complex mountainous areas in western Qaidam Basin.
