Abstract
Logs normalization is an indispensable and basic work for coal-bed methane(Abbreviated as CBM)logging interpretation, and also the key step to realize interpretation from single well to multi-well. B block’s DEN and GR logs come from different time periods and different logging companies. In order to finish the following CBM logging interpretation and lithofacies interpretation, type well plus histogram method is selected to finish DEN and GR logs normalization according to the applicable conditions of different normalization methods and B block actual situation. Type well plus histogram normalization methods can reduce the influence of man-made factors of the CBM logs from the actual application, distribution of logs after normalization are more consistent, which would lay the solid foundation of the following CBM development work.
