| 摘 要： | 气井动态储量的确定是单井合理配产和开发方案制订的重要依据,但对低渗透气藏,由于地层的低渗透性及强非均质性特征,很难准确计算出气井的动态储量。针对此问题,结合低渗透气藏单井的动态生产数据,统计分析了大量气井生产指示曲线,将其划分为3种类型,即标准型、波动型、分段型,并描述了不同类型气井生产指示曲线的表现特征及形成的原因,最终提出了正确利用流动物质平衡法计算气井动态储量的方法。实例分析表明,利用流动物质平衡法计算低渗透气藏单井动态储量所需数据量少,计算结果合理、可信,可为低渗透气藏单井动态储量的确定起到一定的指导作用。 |

| Abstract: | The dynamic reserve of gas well is very important to allocate reasonable production and draw up development programs.However,due to low permeability and strong heterogeneity of low permeability gas reservoir,it is hard to calculate the dynamic reserve correctly.Combined with dynamic production data of low permeability gas reservoir,through statistical analysis,the production index curves of single wells were divided into three types:standard type,fluctuation type,multi-section type,and the characteristics of production index curve of single wells and the related reasons were analyzed.Finally,the method for determining dynamic reserve of different wells based on flowing material balance method was proposed.The case study shows that it is reasonable that using flowing material balance method to calculate the single well dynamic reserves of low permeability gas reservoir. |
| Keywords: | low permeability gas reservoir dynamic reserve flowing material balance method |
