| Abstract: | With the implementation of 3D seismic exploration technique in Zhengzhuang CBM demonstration district in Qinshui basin, research on CBM seismic reservoir forecast technology was carried out. Forecast of distribution range of coal seams, variation of thickness was made by using rock geophysical analysis, extension frequency, frequency division, wave impedance model inversion, etc. Prediction of CBM enrichment zone was made by using forward simulation, seismic frequency fading and calculation of arc length methods. The results of 3D seismic reservoir forecast are remarkable in Zhengzhuang CBM demonstration district, which provided reliable data for well location arrangement, computation of reservoir, development proposal design and adjustment of production well pattern |
| Keywords: | Seismic reservoir forecast rock geophysical analysis frequency division extension frequency wave impedance model inversion forward simulation, |
