Near surface layer modeling |
摘要 |
A method for generating a three dimensional (3D) model of a near surface layer. In one implementation, the method may include generating a one dimensional (1D) geologic model of the near surface layer, converting the 1D geologic model to a two dimensional (2D) geologic model of the near surface layer, converting the 2D geologic model to a 3D geologic model of the near surface layer, and converting the 3D geologic model to a 3D elastic geologic model of the near surface layer. |

1. A method for generating a three dimensional (3D) model of a near surface layer, comprising:
generating a one dimensional (1D) geologic model of the near surface layer with a computer system; converting the 1D geologic model to a two dimensional (2D) geologic model of the near surface layer; converting the 2D geologic model to a three dimensional (3D) geologic model of the near surface layer; converting the 3D geologic model to a 3D elastic geologic model of the near surface layer; applying a surface wave modeling to the 3D elastic geologic model to generate a synthetic shot record in an offset time domain; comparing the synthetic shot record with an acquired shot record of seismic data; and adjusting the 3D elastic geologic model if it is determined that the synthetic shot record varies from the acquired shot record. |
