油藏规模序列法是一种常用的计算区域资源量的方法。文中以对传统油藏规模序列法进行提升改进为目的，介绍了一种基于图形法的油藏规模序列计算流程和原理。首先，简要说明了油藏规模序列法的基本公式原理；然后，重点对该方法的图形化计算流程、分段参数设置、归位计算算法等内容进行了详细介绍；接着，引入了学生t分布校验和概率分布等手段来提高计算的可信度。文中还结合四川盆地南部某气田数据，对图形法计算结果进行了全新的展示和分析，并对传统方法与图形法的优缺点进行了对比，对下一步的改进进行了展望。与传统油藏规模序列方法相比，图形法在过程直观性、结果的详细程度及可信度等方面都有了大的提升和改进。

Reservoir size sequential method based on the Pareto law is a common method for calculating resources. This paper introduces the graphic method, a new way to realize a reservoir size sequential method. Firstly, the paper illustrates the basic theory. Then the paper focuses on the design of graphic algorithm, subsection parameters setting and the processing of position algorithm. The method also uses t-distribution and triangular distribution to enhance the confidence level. Taking one gas field in Sichuan Basin as an example, the calculating results were displayed and analyzed. At last, the paper compares the advantages and disadvantages of the two methods and prospects the possible development in the future. Compared with traditional methods, the new method greatly enhances the calculation performance in intuition, level of specificity and confidence.
