摘要
通过对比三分量共面线圈系与共轴线圈系结构,计算两种不同结构线圈系8个子阵列在三层层状地层中的响应特性,并分析不同的影响特点。结果表明:三分量共面线圈系受结构影响,使纵向响应出现“犄角”现象,但非简单的三层地层响应特征,可通过发射线圈或主接收线圈识别地层边界,计算层厚。通过分析三分量阵列感应两种不同结构线圈系的一维纵向微分几何因子,得到了共面线圈系出现负响应的原因。
By comparing the three-component coplanar coil system with the coaxial coil system,the response characteristics of 8 sub-arrays of two different coil systems in the three-layer formation are calculated,and the different influence characteristics are analyzed.The results show that the vertical response of the three-component coplanar coil system is"angular"due to the influence of the structure,but it is not a simple three-layer formation response characteristic.The formation boundary can be identified by the transmitting coil or the main receiving coil and the layer thickness can be calculated.Furthermore,the coplanar system mechanisms are revealed for negative response through analysis of the one-dimensional longitudinal differential geometric factors of two different coil systems.
