引起储层敏感性的因素很多。以往在确定影响储层敏感性因素时主要是根据经验来分析。本文应用系统聚类的方法从数学角度对储层组成、结构参数与敏感性的亲疏关系进行了研究。通过研究确定了影响储层水敏性、速敏性、盐敏性、盐酸酸敏性和土酸酸敏性的储层组成、结构主要参数。研究结果不仅从另一角度证明了以往的经验,而且还得到了一些新的认识。
There are many factors that cause reservoir sensitivity. In the past to determine the factors that affect the reservoir sensitivity is mainly based on experience to analyze. In this paper, the method of system clustering is used to study the relationship between reservoir composition, structural parameters and sensitivity in terms of math. Through the research, the reservoir composition and structure parameters that affect the water sensitivity, speed sensitivity, salt sensitivity, acid sensitivity of hydrochloric acid and acid sensitivity of reservoir are determined. The results not only prove the past experience from another angle, but also get some new ideas.
