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.Gas reservoir with high sulfur content is a special type of reservoir.During the course of development of gas reservoir with high sulfur content,as formation pressure falls continually,deposited sulfur will result in reduction of formation porosity and permeability,which affects the production of gas reservoir with high sulfur content.The material balance equation for common gas reservoir has not taken the sulfur deposition into account.Therefore,it can not be used to accurately describe the production performance of gas reservoir with high sulfur content.Authors of this paper deduces the material balance equation with high sulfur content considering the sulfur deposition for the closed gas reservoir with high sulfur content,which is helpful to predict production performance of gas reservoir with high sulfur content.

Key words: high sulfur content, gas reservoir, material balance equation, sulfur deposition, reserve calculation
