Land seismic fine exploration technology research and Effect Analysis on Liaohe basin

After four decades of exploration and development in Liaohe Basin, the remaining exploration targets have become more complex, more concealed. The change of exploration object set a higher requirement on seismic data quality. We have carried out the last two years fine seismic acquisition technology, started with the predemonstration, established the appropriate geological model to specific geological targets, carried out fine design and targeted research trials,formed a set of scientific, fine and practical three-dimen-sional seismic acquisition technology under the quantitativequality control, which includs: precise three-dimensional engineering design technology, integrated test technology togeological targets, the best rock excitation techniquue, largescale hazard special concept construction technology,quantitative quality control technology and other key technologies. At the same time, carried out tackling key problems on detailed research and interpretation which has achieved significant exploration results.
