| 英文摘要 | The scattered wave theory has built the basis of scattered wave imaging of the sunken pillar in coal field seismic exploration. When seismic waves meet with the scatter point underground, the waves propagate around and generate scattered waves. And then reflection is formed by enhancing energy interference of scattered waves. Through the numerical modeling, we can receive the scattered waves from the steep dip interface of the sunken pillar in coal seam. After researching wave characteristic on common scatter point (CSP) gathers, we can recognize the scattered waves, and obtain the information of geologic structure underground, including the structure position and the outline of heterogeneous geologic body. Tested with field seismic data, the result of scattered wave imaging indicates that the equivalent offset method (EOM) can reasonably and accurately use the information of scattered waves, and the pre-stack time migration based on EOM is an effective method for the imaging of sunken pillars and inhomogeneous geologic bodies. |
