Abstract

Abstract:

Coalbed gas is combustible and primarily adsorbed on the internal surface of coal matrix, whose main component is methane which coexists with coal petroloy. As an unconventional gas reservoir, there are many differences between coalbed gas and conventional gas reservoirs. In this paper, comparison and summarization of these two gas reservoirs are made from the points of their geological reasons and characteristics, and their accumulation and exploitaion to gas- in- place calculation, which lay a sound foundation for coalbed gas reservoir engineering, well testing, completion and coalbed gas reservoir simulation etc.

Key words: coalbed gas reservoir, characteristics, comparison, origin, exploitation, reserve evaluation
