2015年由美国大发起页岩气革命成功地使美国从油气进口国转变为油气出口国。这使得页岩气成为能源领域关注的热点。页岩气与煤炭和石油相比更为清洁，且储量更为丰富。开发页岩气的两项关键技术是水平井钻井技术和压裂改造地层技术。 然而，由于页岩相比于其他岩石水化学活性更强，导致在水平井钻穿储层过程中井壁极容易垮塌失稳。油基泥浆的使用可以克服上述问题，但成本昂贵且受环保限制。水基泥浆的普及依赖于对页岩水化的深入理解。在页岩水化反应过程中，温度场、离子浓度场、渗流场、应力场均不同程度地作用在井壁周围岩石，而且相互耦合作用随时间不断变化 ... Read More
Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... Read More
Disposal in deep clay geological formations is one of the promising options for disposal of high-level radioactive waste. Yet, they can generate considerable amounts of heat as a side effect of radioactive decay. This paper shows how COMSOL Multiphysics has been used to evaluate the ... Read More
The results of two thermal response tests recently performed on two vertical borehole heat exchangers (BHEs) are presented. The BHEs have the same cross section and a depth of 100 m and 120 m respectively. The evaluation of the thermal properties of the ground and grout are performed by ... Read More
Time-lapse electrical resistivity tomography (ERT) method provides a non-invasive way to monitor subtle sub-surface changes caused by water flow such as in an infiltration test. Problems arise when the inversion models contain artifacts due to measurement errors, rapid change in soil ... Read More
This analysis evaluates the importance of the lateral component of flow on the infiltration of water from parallel strip sources of water on the soil surface. Flow from such sources will be two-dimensional, having both vertical and lateral components. Here we examine the effect of the ... Read More
A comprehensive three dimensional finite element thermal model has been developed using COMSOL Multiphysics® software to understand the thermo-physical behaviour of the uppermost regolith layer of the moon. The model can simulate variable layers, layer thickness and dimensions and can ... Read More
Electric, magnetic and electromagnetic (em) methods are widely used to monitor active volcanoes. A review of such applications is presented in Johnston (cit). Em signals were recorded in correspondence of numerous volcanic eruptions, for example in the case of the Mt. Unzen in Giapppone, ... Read More
Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of ... Read More
鉴于煤岩体“孔—裂隙”双重介质属性，利用COMSOL软件建立了含有孔、裂隙结构的煤岩基质细观结构模型。在模型中采用固体力学模块、层流模块、达西定律模块以及稀物质传递模块，通过自定义参数耦合和边界耦合的方式实现了多物理场的相互耦合作用。针对不同裂隙入口气压情况进行了数值模拟计算和分析，结果表明在裂隙壁附近应力过渡明显，渗透率变化显著，极易发生损伤破坏。研究发现模型中存在某一临界位置，在其两侧渗透率随入口压力的变化规律相反，即模型中距裂隙边界一定范围内的煤岩基质渗透率随入口压力的增大而逐渐减小，但在此范围外的煤岩基质渗透率随入口压力的增大反而逐渐增大 ... Read More
