Abstract: The material balance equation for gas reservoir has been used to determine reserves and OGIP of gas reservoir, judge its driving type and predict its production performance. The gas reservoir with high content of H2S is a special type of reservoir. Its sulfur deposition badly affects the production of such a gas reservoir. The material balance equation for common gas reservoir takes no account of the sulfur deposition, hence it is hard used to completely describe the production performance of gas reservoir with high content of H2S. This paper deduces the material balance equation with high content of H2S considering the sulfur deposition, and provides the material balance equation for the constant volume gas reservoir with high content of H2S.

Key words: gas reservoir, material balance equation, sulfurous gas
