水驱含硫气藏动态储量计算

气藏物质平衡方程可以确定出气藏的原始地质储量，是气藏工程中计算储量的重要方法。由于水驱含硫气藏含有硫化氢，在开采中易于析出硫形成硫沉积，从而会影响到物质平衡法计算气藏储量的结果。在考虑硫化氢的基础上，对原有的物质平衡方程进行了新的推导和验证．结果发现水驱含硫气藏应采用新物质平衡方程计算气藏储量。

Method for Dynamic Calculation of Reserves of Water-drive Sulfurous Gas Reservoirs

A material balance equation of gas reservoir could be used to calculate the initial reserves of the gas reservoir and was an important calculation method. The water-drive sulfurous gas reservoir has its particularity, its sulfur element could be separated to generate sulfur deposition and affect the calculation of the result of gas reserves. To consider the influence of H2S, it deducted and validated a new material balance equation. It was found that hydrogen sulfide would affect the result of reserves. So the hydrogen sulfide is important to calculate the water drive sulfurous gas reserves.
