摘要
根据电磁场理论,建立感应测井仪器相应的数学模型和物理模型,通过加不同方式的源(线圈源和点磁偶极子源)和采用不同的接收方式(线圈接收和点等效接收),进行数值计算并对结果的计算误差做以比较,讨论相应模型加何种源比较合理。
Based on the electromagnetic theory,the mathematical model and physical model of the induction logging is build,and the numerical calculation is conducted by giving different source(coil source and magnetic dipole source) and different receiving mode(coil receiving and point equivalent receiving).By comparing the computational error,which source is reasonable to be a given model is discussed.
