Abstract: The mature development technology and large demands of coalbed methane provide favorable conditions for the development of low rank coalbed methane in S block of eastern Australia. However,there is a lack of systematic research on the characteristics of low rank coalbed methane reservoirs. Therefore,the reservoir characteristics such as coal seam development,coal quality characteristics,reservoir physical properties,gasbearing property and preservation condition for low rank CBM were studied by using drilling,logging and core analysis data from S block,eastern Australia. On this basis,a multi-level fuzzy evaluation method was applied to predict favorable areas in S block. The results show that there are six sets of long flame coal with medium-high ash and a cumulative thickness of 25 m are developed in the study areas. Macroscopically,the coal is mainly composed of semi-bright coal and bright coal,the content of vitrinite is the highest in macerals,and vitrine is the dominated microstructure in coal. The pore structure is mainly mesopores and macrospores,cleats and fractures are relatively developed,and the permeability is 399.85 mD. The average gas content is 4.3 m3/t,and good hydrogeological conditions and temperature,pressure system also ensure the enrichment of coalbed methane to a certain extent. The distribution of favorable areas is mainly controlled by gas content,cumulative thickness and permeability. It is considered that the low rank coalbed methane resources in S block of eastern Australia have good potential for development.

Key words: low rank coalbed methane, gas content, permeability, favorable areas prediction, Australia
