摘要
基于COMSOL多物理场仿真软件对直井和斜井中阵列感应线圈系的测井信号进行三维数值计算,通过计算分析阵列感应线圈系在直井与斜井中的响应特性,得出阵列感应响应特性在直井与斜井中差别较大的结论。通过对电流流向和磁场大小的分析进一步解释形成差别的原因。结论对实际测井解释具有指导作用。
In this paper, the logging signals of array induction in vertical well and deviated well are calculated by COMSOL simulation software, by analyzing the response characteristic of array induction in vertical well and deviated well according to the calculation results, it is concluded that the response characteristic varies widely in vertical well and deviated well. The cause of the difference is further explained with the analysis of current direction and size of magnetic field. The conclusion plays a guiding role for the actual logging.
