多元统计分析是数学地质中常用的方法之一。在油田水研究中应用多元统计分析的方法,将有助于对油田水的离于组合、水化学分类和分布规律等研究的深化和进一步的认识。 一、离子组合及成因的研究 在油田水的研究中,研究油田水的离子组合关系,进而判断其成因是很重要的。离子组合的研究可以运用因子分析。因子分析是对相似系数矩阵进行结构分析的一种方法。它能够在变量所包含的信息相互重叠的复杂情况下,找出影响它们的共同因素,即 Multivariate statistical analysis is one of the commonly used methods in mathematical geology. The application of multivariate statistical analysis in the study of oilfield water will be helpful for deepening and further understanding of the research on the separation of water, chemical classification and distribution of water in oilfields. First, the ion combination and genesis in the study of oil field water, the study of the water ion ion composition of the relationship, and then determine the cause is very important. Ion combination studies can use factor analysis. Factor analysis is a method of structural analysis of the similarity coefficient matrix. It can identify the common factors influencing them in the complex situations where the information contained in the variables overlap
