摘要
The present invention relates to an apparatus for predicting the amount of desorption gas in a shale gas layer through geophysical well logging data analysis and a method therefor, the apparatus allowing the amount of desorption gas in the shale gas layer to be predicted. The apparatus for predicting the amount of the desorption gas in the shale gas layer, comprises: a mineral and organic matter amount analysis part for analyzing the amounts of minerals and organic matters by means of thermal analysis on a shale sample collected from a borehole; a canister gas volume measurement part for measuring a gas amount by using gas inside a canister having the collected shale sample sealed therein; a correlation analysis part for extracting, as a main adsorption mineral, minerals having high correlation with the minerals with respect to the gas amount; a main adsorption mineral amount deriving part for deriving the amount of the main adsorption mineral; and a desorption gas amount prediction part for predicting the amount of the gas adsorbed onto a shale gas reservoir layer, by using the derived amount of the main adsorption mineral and the correlation.
