Abstract：Traditional field seismic data acquisition designing method is not suitable for complex mountainous surface and complex underground structural areas. For that reason, the paper presented geologic target-oriented and forward simulation-based seismic acquisition designing method. Using Huy-gen's-Fresnel principle and Kirchhoff integration wavefield to study the distribution feature of incident and reflected energies of seismic waves, the method presented that the seismic illumination was divided into the illumination of underground interface caused by source and illumination of geo-phones on surface coming from underground reflection interfaces, determining the S/N ratio of acquired data and illumination of geophone on surface, and judged the uniformity of reflected energy acquired on surface spread by analyzing these two kinds of illumination respectively so that can determine the resolution and reliability of seismic data migration imaging. Meanwhile, the method can directly conduct effective analysis and evaluation of acquired data without conducting imaging of seismic data by migration, which is advantageous to modify and improve the parameters of geometry purposefully by designer.
