单一指标评价泥页岩的水化稳定性存在一定的局限性。本文采用多元统计分析方法建立了计算泥页岩水化稳定性综合评价指标的数学方法,即将样品的各个评价指标变量线性组合,挑选前面几个最大的综合因子作为主因子,根据主因子反映原始信息的多少进行加权加和,使多个评价指标变成一个综合评价指标。最后利用该方法对新疆、胜利、中原等油田40种泥页岩样品进行了综合稳定性的评价。
A single index to evaluate shale hydration stability has some limitations. In this paper, a mathematical method for calculating the comprehensive evaluation index of shale hydration stability is established by using multivariate statistical analysis method. That is to say, the variables of each evaluation index of the sample are linearly combined, the first few largest comprehensive factors are selected as the main factors, The amount of information is weighted sum, so that a number of evaluation indicators into a comprehensive evaluation index. Finally, this method was used to evaluate the stability of 40 shale samples in Xinjiang, Shengli and Zhongyuan oilfields.
