Research on Enhanced Coalbed Methane in Lu'an mining area

This paper analyzed the production history of coalbed methane wells in Lu'an mining area.Then combined with the techniques of enhanced coalbed methane at home and abroad,the coal reservoir's characteristics and the coal and rock mass's mechanical properties in Lu'an mining area was researched.The article emphatically analyzed the effect of the mechanical properties on the fracturing technique.Finally,the paper put forward the measures for enhancing coalbed methane,which are suitable for the study area,including combination technique of vertical well and medium-radius horizontal well,the air or foam drilling technology,nitrogen foam fracturing technique and so on.
