Abstract

Summary form only given. This paper analyzed of the present situation and technology problems in coal mine gas drainage in China. Analyzing 2013 Chinese CBM production of domestic gas production and gas extraction from the status quo, ground extraction of coalbed methane production, mine gas extraction efficiency have failed to meet the national targets set by the 12th Five Year Plan. The main problem of coalbed methane production is the low coalbed methane recovery efficiency because of the easy damage of coal seam and poor permeability. Improvement of permeability and reduction of coal damage is hard for current technology. This paper introduces the shock wave generation technology and the mechanism of application shock wave in improvement of conventional reservoir and the effect on oil and water wells.
