摘要

The secondary biogenic coalbed gas, a new genetic and energy source type of coalbed gas in China, has been found in Xinji, Liyazhuang and Enhong areas. The essential characteristics of this type of gas are: i the major component of the gas is methane, with Ct/Ct s value higher than 0.99, indicating that the gas is part of dry gas; ii the Sl3Ci value is in the range of -61.7%c to -47.9%c, mostly lower than -55%c, which is much lower than the estimated
