Soil’s electromagnetic properties adversely affect the performance of electromagnetic induction (EMI) sensors and if conditions are severe enough, render them useless. A simple circuit model is often used to express the electromagnetic induction response of a target analytically. This ... Per saperne di più
In this study, a model of in-situ geothermal energy piles was constructed using COMSOL Multiphysics® software. Geothermal energy piles serve two purposes, first to transfer building load into the subsurface, but also to extract thermal heat from surrounding soils. This is achieved using ... Per saperne di più
The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with ... Per saperne di più
The subsurface thermal structure in presence of groundwater recharge/discharge has been obtained by applying the Robin type boundary condition at the earth’s surface. The Robin type boundary condition involves the effect air temperatures at the surface which are taken as exponentially ... Per saperne di più
COMSOL Multiphysics® software has been used in computational geodynamics for years. Because very high pressure in the mantle even significantly compressed the mantle up to ~40%, it is crucial to consider the mantle compressibility in computational geodynamics. COMSOL Multiphysics allows ... Per saperne di più
Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... Per saperne di più
This study focuses on the design and optimization of a logging while drilling (LWD) tool with look-ahead detection capabilities, which is widely used in measuring formation resistivity and detecting formation boundaries ahead of the drill bit during oil and gas drilling operations. The ... Per saperne di più
Overpressure-driven hydrofracture zones are pipe-like structures and widespreadly develop in sedimentary basins worldwide. They have the ability to penetrate vertically for multiple kilometers, acting as pathways for fluid on the basin scale. When the hydrofracture zone penetrates the ... Per saperne di più
目前我国页岩气的勘探开发也已取得了突破性成果，但是随着页岩气的开发，仍存在两大问题困扰着科学工作者和现场工程师：（1）页岩气开发过程中的渗透率演化规律尚未摸清；（2）在产气过程中，页岩气在产量上往往呈现出不确定性；针对以上问题，本文发展了基于孔隙结构特征变化的气体微观扩散模型，建立了微观尺度模型用以研究页岩基质有机质与无机质气体流动-微观变形之间的耦合作用。通过离散模型对分析了微观尺度页岩基质不同矿物组分（有机质和无机质）力学参数、孔隙结构、气体流动参数差异对气体微观扩散能力的影响机制，建立了由孔隙结构和流体压力控制的有效扩散模型描述气体微观扩散行为 ...

随着天然气需求的不断增加，页岩气作为一种重要的非常规能源，对于国家能源安全和经济发展具有重要意义。然而，页岩气的有效开采受限于对其储层微观力学特性的深入了解，宏观尺度很难获得页岩各组分的力学性质。因此，我们才用纳米压痕技术来研究页岩微观尺度下的细观力学特性，并基于X射线衍射（XRD）、自动矿物分析系统（TIMA）等先进技术分析，建立微观尺度下的固体变形-气体流动控制模型，分析评估微观产气影响机理，主要研究工作如下： （1）采用纳米压痕实验技术，对页岩进行了不同加载角度下的保持荷载实验以获得页岩微观尺度下的力学参数，如杨氏模量、硬度以及蠕变 ... Per saperne di più
