摘要:
火山岩相对于砂岩储层成分复杂得多,对砂岩储层进行的研究对火山岩储层并不完全适用。CO2在储层中一般是以超临界状态存在,传统的测井解释中并没有考虑。通过数学方法的自动识别则将这一切影响都包含在内,补充了传统的测井解释手段。对CO2的测井响应特征进行讨论,分别用Fisher判别、最小平方误差准则函数、谱系聚类分析等3种方法对储层进行分类识别,对这3种方法进行了比较,谱系聚类分析显示出很好的判别效果和应用性,优于其他2种方法。
Abstract:
As the composition of volcanic is much more complex than sandstone reservoir, the researches on sandstone reservoir before are not completely suitable for volcanic reservoir. CO2 ordinarily exists in supercritical state in the reservoir, but the traditional well logging interpretations never consider this case. The automatic identification by mathematical methods considers all the effects, which immensely supplements to the traditional well logging interpretation methods. Discussed are the log response features of CO2 firstly, and then the reservoirs are classified and identified by Fisher discrimination, the least square error rule function and lineage clustering analysis method. At last, comparison of the three methods indicates that the lineage clustering analysis method shows better discriminant results and applications, superior to the other two methods.
