将模糊数学的有关原理，系统地应用于压裂（包括复压）的选井选层、部分关键设计参数的研究和确认以及最终压裂方案的优化决策中。在紧密结合现场实际的基础上，综合考虑了多种影响因素并将其量化，因此较以往的单因素分析法更为合理。此外，在权重的确定上，尝试应用了灰色理论中的灰色关联度法，将模糊数学与灰色理论有机地结合起来，得出的权重结果基本符合经验判断。本文的三部分研究内容，前后相接，构成一项系统工程。研究方法简单适用，现场可操作性强。研究结果经矿场实例验证及其它可靠手段检测，可信度较高，并已获得了较好的经济效益。
The relevant principles of fuzzy mathematics are systematically applied to the well selection and selection of fracturing (including pressure recovery), the research and confirmation of some key design parameters and the optimization decision-making of the final fracturing scheme. Based on the actual situation in the field, we comprehensively considered and quantified various influencing factors, which is more reasonable than the univariate analysis in the past. In addition, in the determination of weights, we try to apply the gray relational method in gray theory, and combine the fuzzy mathematics and gray theory organically. The weighted results are basically in line with the empirical judgment. The three parts of this article, before and after phase, constitute a systematic project. The research method is simple and applicable, and the field is easy to operate. The result of the study is verified by field examples and other reliable measures, which has a high degree of credibility and has obtained good economic benefits.
