CBM Reservoirs Condition and Gas Controlling Features of Liulin Block,in Eastern Margin of Ordos Basin

摘要

Based on the detailed analysis of the reservoir characteristics for coalbed methane (CBM) of Liulin block in eastern margin of Ordos Basin,the geological basis of CBM,coal petrology,gas content,adsorption and reservoir physical properties are investigated.The results reveal that the CBM reservoir,with kinds of beneficial parameters (including porosity,permeability,reservoir pressure and gas content),has very good potential for the CBM generation.And it is propitious to CBM concentration,and is very suitable for exploitation.
