Abstract:

During the exploitation process of unconventional adsorbed gas reservoirs, as formation pressure decreases, adsorbed gas will be desorbed and make adsorbed layer decrease and free gas space increase. At present, the material balance equation considering adsorbed layer volume variation has not been established and has not been applied to research the influence of adsorbed layer volume variation and density on adsorbed gas reservoir reserves. This paper firstly established newmaterial balance equation considering the adsorbed layer volume variation. The application cases proved the applicability and reliability of this equation, and it is cognized that adsorbed layer volume variation and density have greater influence on natural gas reserves estimation.
