Due to the specific surface conditions as well as the complex and varied surface structure of the beach and shallow sea area, the exploration work in such an area is different from both continental exploration and sea exploration. In the amphibian zone, in particular, there exist two working means (sea and continental means). Based on a systematic study of such field collection links in the field as the excitation seismic source, the detector and the observational system, the authors put forward the method for solving the difficult problem of collecting high-quality seismic data. On the basis of a thorough investigation into the interference wave suppression and the difference correction, a complete set of high-precision and practical special techniques for oil and gas exploration in the beach and shallow sea area was developed, and the results show that its geological effect is satisfactory.
