摘要:

气藏物质平衡方程是气藏工程中的重要理论,可以确定气藏的原始地质储量和可采储量,判断气藏的驱动类型,以及预测气藏未来的开发动态。高含硫气藏是一种特殊的气藏类型,该类气藏在气体开采过程中,随着地层压力不断下降,会产生硫沉积现象。常规气藏物质平衡方程没有考虑硫沉积现象,因此,高含硫气藏物质平衡方程与常规气藏物质平衡方程存在一定的差异,直接利用常规气藏物质平衡方程预测高含硫气藏的开发动态会产生一定误差。在考虑硫沉积的基础上,针对封闭气藏的情况,推导了高含硫气藏的物质平衡方程,为高含硫气藏开发动态分析及预测提供了一种有效的手段。

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
