COALBED METHANE EXPLORATION AND STORAGE PREESTIMATE USING MULTI-CHANNEL TELEMETRY METHOD OF THE COAL SEAM RESISTIVITY

摘要

The coalbed methane, a kind of dissociative gas, absorbed in the surface or inside of the coal holes or in the cranny of the coal. Coal seams, both the source rock and the storage layer of the methane, usually is considered to be the exploring target before searching the methane. Yet, not all the coal layers have the storage of methane, people must make further exploration to seek for coal storing characteristics existed in the seam holes or the cranny growth section that suitable for concentration of the methane to lower the risk of the methane exploration. The coal seams in China suffered many times of reconstruct and destroy of the lithosphere movements that greatly enlarge the difficulties of the exploration of the coalbed methane.
