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。
In the calculation of geological reserves of sulfur-bearing gas reservoirs, the material balance equation of the traditional gas reservoir does not consider the influence of sulfur precipitation on the equation itself. Sulfur-bearing gas reservoirs continuously release elemental sulfur as the pressure decreases, and the formation of sulfur will have a great influence on the balance calculation of gas reservoirs by conventional materials, thus failing to fully understand the gas field dynamics. This paper mainly discusses a new method of calculating the reserves of closed high-sulfur gas reservoirs, introduces the coefficient of variation and the solubility of sulfur to correct the original equation, and makes the calculation results of geological reserves of sulfur-containing gas reservoirs more accurate.
