Abstract

The present invention discloses a method for analyzing coalbed methane geological selection of a multi-coalbed high ground stress region, including the following steps: defining the concepts of a favorable area, a sweet spot area, and a sweet spot section; carrying out the selection process on the favorable area, the sweet spot area and the sweet spot section in sequence; selecting different indicators for the characteristics of each stage, explicitly presenting key indicators and reference indicators at each stage, and providing an indicator with one-vote veto rights in the key indicators; and carrying out comprehensive analysis to obtain favorable planar areas and vertical intervals of coalbed methane exploration and development in the multi-coalbed high ground stress region. The method of the present invention provides instructions on coalbed methane geological selection of a multi-coalbed high ground stress region, and is of great significance for the development of coalbed methane.
