煤系地层建模及仿真

Coal Measure Strata Modeling and Simulation

为了建立接近实际煤层的仿真模型,根据煤层的形成特点和EDA介质的特点,用等效EDA介质对煤系地层进行模型简化。利用COMSOL进行了弹性波在煤系地层模型中传播的仿真。通过仿真和实际理论对比,说明了建立的EDA等效煤层模型是合理的,并且得到了弹性波在煤系地层的瞬态传播图,同时验证了煤层的波导特性。

In order to establish realistic simulation model of the coal strata,according to the characteristics of the formation of the characteristics of the coal seam and the EDA media,we use the equivalent EDA media to simplify model.We use COMSOL to simulate propagation of elastic wave in coal strata model.Through simulation and theoretical comparison,it illustrates that the establishment of EDA equivalent seam model is reasonable.And we get the transient propagation graphics elastic wave in coal strata,and verify the waveguide properties of coal strata.
