摘要
The static issue is one of the core techniques in coalbed methane (CBM) seismic data processing. According to the characteristics of coalbed methane seismic data in Qinshui Basin, the authors simply analyze in this paper the principles of different static methods. Through the analysis and application of actual data, the authors develop an effective processing sequence including refraction static correction, first break residual static correction and reflected residual static correction to solve the coalbed methane static problem in this area. The processing sequence of coalbed methane seismic data processing laid a good foundation for the geological structure characteristics research, coal reservoir fracture prediction and gas-bearing layer detection.
