摘要
天然气水合物作为一种潜在的替代能源和环境扰动因素,相关研究仍然面临着水合物储层微观结构量化表征不足的问题,而分形理论为此提供了良好的思路与手段。首先介绍分形理论基础,然后对分形理论在水合物研究领域的应用情况进行综述,接着概述含水合物沉积物有效孔隙分形理论,最后对研究进展进行总结并展望未来分形理论在水合物研究领域的可能方向。
Natural gas hydrate is widely regarded as a potential new energy source and a possible trigger of environmental issues.However,the research community of gas hydrate are still faced with difficulties in quantifying pore-scale structures of the hydrate-bearing sediments.Based on our observation,the difficulties can be well solved by using fractal theory.In this paper,we firstly made an introduction to the basis of the fractal theory,followed by a review of fractal theory applications in the gas hydrate community.Then,a fractal theory for quantifications of the effective pore space in hydrate-bearing sediments is presented,and a summary and some suggestions for gas hydrate related fractal researches in the future are finally provided.
