Acquisition Technology and Application of Shale Gas Seismic Exploration in Complex Mountains

Acquisition technology of shale gas seismic exploration in complex mountainous areas can solve a series of problems faced by shale gas seismic exploration, such as complex surface environment, strong underground heterogeneity, rapid lithological change and deep exploration horizon. Starting from the four key links of observation system design, excitation, reception and quality monitoring of shale gas seismic exploration and acquisition, targeted analysis, research and practice have been carried out, and a series of wide-azimuth and high-density 3D seismic exploration and acquisition techniques and methods suitable for complex mountain shale gas have been gradually formed. That is, observation system design demonstration based on “double complex” 3D model and remote sensing technology, geographic information system, shot point optimization, dynamic observation and data quality intelligent evaluation technology. The above technical methods have been used in the shale gas exploration project in southern marine mountains to obtain high-quality seismic data. Practice has proved that this method is feasible. It provides a reference for the subsequent research of target seismic exploration acquisition technology.
