[1] Planetary Sciences Division, Physical Research Laboratory, Ahmedabad, Gujarat, India

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

We use GPS measurements and Finite Element analysis to investigate strain accumulation in the interaction between active fronts of the Southern Alps and Dinarides at the northern edge of the Adriatic micro-plate. We develop a three dimensional model of the area taking into account the ... Read More

Simulation Of Soil Remediation Polluted By Hydrocarbons Using A Non-Thermal Atmospheric Plasma

J. Rojo, S. Ognier, and S. Cavadias
Laboratoire de Génie des Procédés Plasmas et Traitements de Surfaces, University Pierre et Marie Curie, Paris, France

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent ... Read More

Lava Tubes at Shallow Depth

M. Di Bari, and G. Zito
University of Bari, Italy

Many theoretical studies concerning lava tubes focus on the thermal disturbances generated on the earth surface. Recently a solution was suggested, where a lava tube located at a great depth h in the soil, where the ratio between h to the major axis of the ellipse a is ... Read More

页岩气水基钻井液钻井井壁稳定性研究 new

[1] 西南石油大学

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

考虑流固耦合的煤层气压裂水平井数值模拟研究 new

[1] 西南石油大学油气藏地质及开发工程国家重点实验室,四川 成都

煤层气开采过程中煤层所受应力、孔隙压力的变化以及气体的吸附解吸,会导致煤体骨架和孔隙体积发生变化,改变煤层的渗流能力。基于多孔弹性理论、渗流力学并考虑吸附变形,建立了煤层压裂水平井的物理模型,并建立了煤体变形和气体流动的全耦合数学模型,推导出了渗透率的动态变化模型。利用数值分析软件Comsol Multiphysics对煤层气的开发特征及规律进行了数值模拟,最终实现对模型中关键参数的敏感性和压裂裂缝参数的影响进行分析。 Read More

注蒸汽热力采油是稠油开发的一种有效方法,它涉及到储层地质、采油工程、传热学、经济分析等多门学科,是一项复杂、技术难度大的系统工程。研究蒸汽吞吐的热力学过程,包括井筒内饱和水蒸汽温度/压力传输、储层内多相流传质传热等,对于优选热采井生产方式和工作制度、提高采收率具有重要意义。本研究针对注蒸汽热采过程,将井筒与储层作为一个统一的系统,考虑井口注汽参数与储层吸汽能力之间的协调关系以及储层温度场、流体场、固体场之间的耦合关系,基于连续介质力学、流体力学、渗流力学、热弹性力学及传热学等相关理论,建立了反映变温、变形影响的井筒-储层耦合数学模型。基于COMSOL ... Read More
