Abstract：The environmental characters of Kendong beach and shallow-sea area brings a lot of difficulties to seismic exploration, which are ①large variation of surface condition, poor shooting and receiving conditions and easy to form multiple ghost reflection interfaces, resulting in multiple interference waves and affecting the quality of seismic data; ②difficulty in geophone positioning because of influence of tide and sea-water, affecting data processing precision; ③multiple survey patterns may exists in seismic acquisition of transitional zone because of influence of natural conditions, affecting the seamless link of data in transitional zone; ④shooting by airgun and receiving by hydrophone in water area, and shooting by dynamite and receiving by swamp hydrophone in land area of beach, resulting in large difference in energy, frequency and phase of seismic waves. Due to the difficulties of seismic exploration in Kendong beach and shallow-sea area, the paper formed a set of feasible seismic exploration techniques in beach and shallow-sea area, including ①seismic acquisition technique, such as near-surface structure survey technique, seismic wave shooting and receiving techniques, precious geophone positioning technique and geometry designing technique; ②seismic data processing technique, such as bias correction technique, ghost and period-changing sea-bottom singing suppressed technique. The gained data have been greatly improved in both S/N ratio and resolution through application of this set of seismic exploration techniques in Kendong beach and shallow-sea area, and seamless link of seismic data with multiple geometry patterns has been realized.
