  • A new methodology is presented to predict coalbed gas reservoir parameters at relationship of seismic attribute and geological information.The basic methodology is to build a mathematic model through the regression analysis of the mathematic geology.Two achievements have been acquired. The first is that the equation of thin bed coal seam thickness to the reflecting amplitude; the second is that setting up the regression equation: one is the porosity-to-instantaneous frequency; the other is the gas-product percentage to the reflection amplitude. At the end, application of the research results to the Shanxi Qinshui coalbed gas seismic exploration project shows a satisfaction results and produce great economic interests.The study results are useful for inereasing the mining safety and decreasing the mining risk,as well as developing a new application field.
