摘要： 分形几何理论的产生和发展为刻画非欧几里得几何系统(即分维系统)的性质提供了有效手段,使用这一工具可以重新认识油气渗流规律,对传统的描述油气运动的数学模型加以改进并应用于试井分析中。根据传统模型图版制作原理,制作了分形导数图版。传统模型的拟合与分形导数图版的匹配效果很好,所求得的各种参数更接近地下真实的复杂情况,这对于油气田开发工作有很重要的指导意义。

Abstract: Formation and development of fractal geometry provides an effective tool for describing the property of non-Euclid geometry system (i.e. fractal system). This tool can be applied for re-understanding of oil-gas flow regularities, and improvement of traditional mathematic models for describing oil-gas movement, as well as application of it into well test analysis. The fractal derivative chart is made by the mapping principle of traditional model chart and seems to be well matched with actual data simulated with traditional model, each parameter given by it is closer to in-situ complicated conditions. The chart can be applied for development of oil-gas fields.

Key words: well test analysis, fractal mathematic model, chart
