低渗透气藏储量早期预测

EARLY PREDICTION OF RESERVES OF LOW PERMEABILITY GAS RESERVOIR

气藏早期地质储量的确定对开发方案的制定、开发设施的设计以及气藏价值的评估十分重要,低渗透气藏早期地质储量的确定一直是一项比较难的工作。针对此问题,提出了利用流动物质平衡法、油藏影响函数法以及采气曲线法来早期预测低渗透气藏或单井控制地质储量。经过实例分析说明以上三种方法切实可行,还对三种方法自身的适用条件以及各自的优缺点进行了简要分析。

Ascertain low permeability gas pool′s geological reserves in early stage are very important to establish development program,design development facility and evaluate gas pool′s value.The prediction of low permeability gas pool′s reserves always was a hard work.Contrapose this problem,the paper presented flowing material method,oil reservoir influence function method and gas recovery method to predicted low permeability gas pool′s geological reserves in early time.Base on the case analysis the self apply condition and relative merits of the three methods in the paper.
