摘要
针对层状介质,结合了费马原理、Radon变换,提出了基于等效孔隙介质模型的CT技术物性参数成像法,并使用遗传算法对速度、孔隙度、岩石密度以及波阻抗进行了反演。理论分析与实例计算结果表明:该方法简化了波在双相孔隙介质中的传播方程,具有一定的实用价值,能够有效解决含油区的勘探问题。
A new CT method of physical parameters for stratiform media including Fermat principal and Radon transform,based on the equivalent model of porous media,is studied,and inversion of physical properties such as velocity,porosity,density and wave impedance is made availing of algorithm.From theoretical analysis and result of inversion,it could be drawn that the method is of practical value and may lead to effective prospecting for oil,simplifying wave propagation equations in dual phase porous media.
