摘要
在含硫气藏的地质储量计算中,传统气藏物质平衡方程未考虑硫的析出对方程本身的影响。含硫气藏随压力的降低会不断地析出单质硫,而硫的形成将对传统物质平衡计算气藏储量产生很大的影响,进而不能对气田动态形成全面的认识。主要探讨了封闭高含硫气藏储量的新型计算方法,引入了偏差系数和硫的溶解度对原方程进行修正,使含硫封闭气藏的地质储量计算结果更为准确。
Traditional material balance equation for OGIP calculation of sulfur-bearing gas reservoirs does not consider the influence of sulfur separation on the equation itself. Sulfur will continue to separate along with reservoir pressure decline, while the separated sulfur will have a big effect on OGIP calculation with traditional material balance method, thus affecting justified understanding of gas reservoir performance. This paper mainly discusses a new calculation method of OGIP for closed, high sulfur content gas reservoir. Z-factor and sulfur solubility are applied to modify the traditional equation in order to provide more accurate OGIP of closed sulfurous gas reservoirs.
