基于FracMan的储层裂缝建模技术

FracMan-based Reservoir Fracture Modeling

基于离散裂缝网络模型的裂缝建模是目前最先进的裂缝建模技术,FracMan是在该技术基础上发展起来的裂缝建模软件。通过对FracMan原理及实现方法进行分析,指出了FracMan在裂缝建模中较传统双孔连续统一体方法存在巨大优势及特色。此外通过简单示例,对单井裂缝方位、裂缝密度参数分析,综合地震、测井、岩心、露头等基础数据,建立了示例工区裂缝模型,最后在肯定了离散裂缝网络模型技术理论和方法的先进性后,指出了其在应用中存在的不足。

Fracture modeling based on discrete fracture network model is the most advanced technology at present. FracMan is just a software for fracture modeling developed on the basis of this technology. After analysis of FracMan theory and its realization approach, it is deemed that, compared with conventional dual-pore continuum methods, the FracMan has its own characteristics and huge advantages. Moreover, both fracture azimuth and density in single well are also analyzed for a simple example. After that, a fracture model is developed according to some data from seismic, well logging, core analysis, and outcrop observation. At last, it is shown that this technology of discrete fracture network model is advanced in terms of its theory and approach. However, some disadvantage can be found in its application.
