模糊Petri网在油田开发设计领域的应用研究

Research on Fuzzy Petri Net and Its Applications in the Field of Oil Development and Design

油田自上世纪开发以来,已经积累了众多的不同类型油田的开发设计方案,借鉴已有的油田开发设计方案是非常必要的。为了使用户能够快速准确地找到所需方案,本文通过研究模糊Petri网的定义和性质,建立一个十元模糊Petri网模型,将模糊Petri网的建模方法应用于此,通过调节方案搜索条件的权值大小,控制该项条件在方案筛选过程中的重要程度,根据模糊Petri网的推理得出方案的相似度。

Since the development of oil field in the last century has accumulated a large number of different projects in the field of oil development and design, it is very necessary to draw lessons from the existing projects. In order to make the user find quickly and accurately the required projects, this paper introduced the definition and properties of fuzzy Petri net, and gave a model of fuzzy Petri net. The fuzzy Petri net modeling method was applied by adjusting the size of the weight in the premise condition to control the importance of condition during selecting projects. The similarity of the project was obtained based on the fuzzy Petri net reasoning.
