The Influence of Tectonic Characteristics on the Accumulation of CBM in H Area

Article Preview

Abstract:

There are several geological factors affecting the accumulation of CBM, including tectonic condition, burial depth, coal thickness, coal rank, gas content, permeability, reservoir pressure, desorption pressure and hydrological condition, etc. This article analyzes the influence of tectonic characteristics on the accumulation of CBM in H area, combining the tectonic characteristics and the actual production data, finally conclusions can be drawn that the uplifting movement of crust after coal-forming period could break the original adsorption equilibrium, then CBM would escape under unfavorable preservation condition; different scales of fractures and folds formed by tectonic movements play an important role in the preservation and dissipation as well as in the enrichment and accumulation.
