中文摘要：

气藏物质平衡方程是气藏工程的重要方法，可以确定气藏的原始地质储量和可采储量，也可以判断气藏的驱动类型，并预测气藏的开发动态。高含硫气藏是一类特殊气藏。硫沉积现象严重影响了这类气藏的开发。常规气藏物质平衡方程没有考虑硫沉积现象，因此不能用以完整地描述高含硫气藏的开发动态。在考虑硫沉积的基础上，推导了高含硫气藏的物质平衡方程，针对定容气藏的情况，得到了定容高含硫气藏的物质平衡方程。

英文摘要：

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.
