ADVANCES AND TENDENCIES IN GEOLOGICAL RESEARCHES ON COALBED METHANE
2003
We are presently involved in the challenge of geological research on coalbed methane, including: a)to reveal the coordinated relationship between the generation and the preservation of coalbed methane and to discover the forming mechanism, pool-forming types and distribution rules of coalbed methane pools under complex geologic conditions by studying on the geologic processes and dynamical mechanism of pool-formation; b)to analyse the processes of diffusion, percolation, migration, escaping and accumulation of coalbed methane which are commonly restricted by coal-water-gas coupling connection and coal-reservoir features by studying on the reservoir systems and accumulating-disseminating mechanism of coalbed me-thane; c)to probe into the mutual stimulating mechanism between the geophysical and geochemical field and man-made reconstruction and intensified exploitation and to effectively predict the results of exploration and exploitation of coalbed methane by studying on the field effects during the economical and high-efficiency exploitation of coalbed methane pools.
