The main problems existing in the exploitation of coalbed methane

摘要

Coalbed methane is one of the important unconventional energy, due to its characteristics determined there must be taken effective fracturing modification measure to get industrial gas flow, this paper analyzes the damage mechanism of fracturing fluid, the selection of additives in fracturing fluid and the methods of enhancing coalbed methane, and puts forward some corresponding suggestions to improve the recovery of CBM wells supporting a certain practical significance.
