地质导向对煤矿井下定向钻进意义重大,而随钻伽马测井是地质导向的重要参数。随钻伽马测井仪既能测量钻孔轨迹,又能测量地层放射性以判断地层的岩性。由于轨迹测量的测斜仪采用磁感式传感器,而伽马探测器为软磁性材质,因此伽马探测器影响测斜仪的方位测量精度。本文从轨迹测量的基本原理出发,利用COMSOL有限元分析伽马探测器对测斜仪周围磁场的影响,并在实验室进行实际测量验证,提出利用GRNN神经网络建立影响校正模型,对其影响进行校正,取得较好应用效果。 扩展阅读

饱和冻土水热耦合数值模拟与试验验证 new

冻融循环引起的破坏是季节冻土区渠道的主要病害,其发生与温度梯度和水分迁移有密切的联系。为了研究冻融循环作用下土体温度变化与水分分布,多场耦合理论应运而生。但目前存在的多场耦合模型大多采用了过多的参数,其中的一些参数甚至难以确定。因此本文基于Harlan流体动力学模型,以温度和孔隙率为变量建立了一个实用的多场耦合控制方程,然后采用COMSOL Multiphysics中的数学模块中的系数型偏微分方程(PDE)对土体温度场和水分场进行模拟,并与室内水分迁移试验进行对比,证明了该耦合模型的有效性。最后以北部引嫩工程渠道为例,建立模型试验,所得试验结果与模拟结果也是十分接近。 扩展阅读
