Abstract: While the Ordos Basin is recognized for its substantial hydrocarbon exploration prospects, its rugged loess tableland terrain has rendered seismic exploration exceptionally challenging^1-3. Persistent obstacles such as complex 3D survey planning, low signal-to-noise ratio raw data, inadequate near-surface velocity modeling, and imaging inaccuracy have long hindered the advancement of seismic exploration across this region. Through a problem-solving approach rooted in geological target analysis, this research systematically investigates the behavioral patterns of nodal seismometer-based high-density seismic acquisition in loess plateau. Tailored advancements in waveform enhancement and depth velocity modelling methodologies have been engineered. Field validations confirm that the optimized workflow demonstrates marked improvements in amplitude preservation and imaging resolution, offering novel insights for future reservoir characterization endeavors.
