摘要
基础的地震地下流体数据处理方法有求均值、去趋势性变化、频谱分析、自定义函数拟合、井孔水温梯度曲线绘制等,这些方法虽然已编写有专业的处理软件,但由于观测井孔的条件各异、数据动态形态各异等原因,用同一软件处理往往较难有理想的结果,特别是对于一些有针对性的、区域性的研究,这种情况下专业的数学工具就体现出其优越性。MATLAB在数值计算方面首屈一指,可用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境。本文利用该软件进行地下流体数据处理最基础方法的实现,并进行实例分析。
The basic methods for analysis of underground seismic fluid data include averaging, detrending changes, spectrum analysis, custom function fitting, wellbore water temperature gradient curve drawing, etc. There is some professional software to carry out these methods. However, these software have poor adaptability, and are challenged to deal with various types of data as different boreholes, different well-aquifer systems, and so on. In this case, the professional mathematical tools reflect their superiorities. MATLAB is number one in numerical calculations of mathematical applications, which has advanced technical computing languages and interactive environments for algorithm development, data visualization, data analysis, and numerical computation. In this article, the implementation and examples of these analyzing methods are shown.
