The method of using qualitative identification of coalbed methane reservoir logging method was mature, how to explian quantitative interpretation of coalbed methane reservoir parameters was the key of coalbed methane reservoir logging evaluation. With the progress of coalbed methane exploration technology, the method of using logging data evaluated coalbed methane reservoir increasing, various technologies emerged in endlessly. But a lot of practice showed that due to the particularity of coalbed methane reservoir, although each evaluation technology had the support of basic theory, but also had some limitations. In order to solve this problem, the coalbed methane logging evaluation method and the related problems in practical application were discussed.
