, 2011 以国土资源部广州地质调查局2007年5月在南海北部神狐海域SH7站位的钻探、测井数据为基础,建立了实际水合物藏分层地质模型,主要包括上盖层、水合物层和下盖层,其中上、下盖层均为可渗透的沉积物。本文利用单一水平开采井,进行了热吞吐法开采水合物的数值模拟。给出了选取合理的注入速度和生产速度的准则。模拟结果表明,开采过程中水合物分解区域主要集中在开采井周边区域,在注热阶段和生产阶段,地层中的水合物分别经历合成和分解两种过程,期间有明显的盐水浓缩和稀释效应。在本文条件下 ...

, 2015 增强型地热系统(EGS)旨在经济开采地下3~10 km区域干热岩蕴含的热能,并用于地面发电。EGS经济性与其采热性能直接关联,人工热储内热交换过程是需要重点研究的内容。热储内裂隙形貌及分布对采热过程有重大影响。基于热储裂隙开度和长度的分形特征,本文建立起EGS分形分叉网络模型,推导出EGS采热速率表达式。分析发现泵功、裂隙最大开度、扭曲率分形维数、裂隙开度分布分形维数 ...
