MODELING METHOD FOR GAS CONTENT OF CBM RESERVOIR ROCKS

摘要

The present invention relates to a modeling method for a gas content of coalbed methane (CBM) reservoir rocks. According to the present invention, based on similarity of a sedimentary environment, proximity of a contour, and distance proximity of a technical analysis bore hole, a region to be developed is divided into a plurality of areas to individually analyze a gas content in each area to be modeled. In the present invention, through data by technical analysis, a tendency function is set with respect to each of an ash content, a water content, and a gas content, and as geophysical logging data is input to the tendency function, a property of matter at each depth can be acquired with respect to all drill wells. Therefore, reliability can be improved when using a statistic technique.;COPYRIGHT KIPO 2017
