元坝气田长兴组未开发气藏采收率初探

摘要

The Changxing reservoir in the Yuanba Gas Field is a deep-buried carbonate gas pool with high sulfur content, low porosity and low permeability. At present, the Changxing reservoir is undeveloped. Various methods such as empirical equation, analogy and material balance have been applied to determine the recovery rate of different calculation units. Technologically recoverable reserves have been calculated, providing an important basis for preparing development program scientifically and reasonably.%元坝气田长兴组气藏属于高含硫、超深层、低孔渗碳酸盐岩气藏,目前处于未开发阶段,技术可采储量计算中采用经验公式法、类比法、物质平衡法等多种方法进行综合分析,确定了各个储量计算单元的采收率,完成了技术可采储量的计算,为科学、合理地编制元坝气田长兴组气藏开发方案提供了重要依据.
