Abstract: According to the geological and geophysical response characteristics of Taiyuan-Shanxi formations shale of Zhongmu block in Henan province, a 3D seismic exploration technology suitable for Zhongmu block was obtained and applied through the integration of high-precision 3D seismic acquisition, processing and interpretation. The application results indicate that in terms of seismic acquisition, the technical requirements of high coverage and small surface elements are realized by optimizing the observation system and excitation conditions. In respect of seismic data processing, attentions are paid to fidelity-keepings, amplitude preservation and regularization. As for seismic data interpretation, based on sequence division, fine interpretation, high-quality reservoir and fracture prediction, etc., it has laid a solid foundation for shale gas exploration in this area.
