摘要
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 concerned principles of fuzzy mathematics are systematically applied to the selection of well and zone,to the research and determination of partial key design parameters and to the optimization decision of final fracturing plan in fracturing (including repeated fracturing)design,which is more reasonable than the single factor analysis method used in the past because of comprehensively considering many affecting factors and their being quantified on the basis of closely combining with practice.In addition,the obtained weight,which is determined by use of the grey associativity method in grey theory through organically combining furry mathematics with grey theory,basically tallies with the result by an experiential judgement.Three parts of the research are well linked from beginning to end,forming a system engineering.The study method is simple an suitable with strongly operating property on the spot.Through verifying by an example on the spot and examining by other reliable means,it is shown that the study result is of relatively high creditability.And a quite good benefit has been already obtained..
