Three-component induction coil system in the uniform formation of the response characteristics

本文根据三正交线圈系结构,对仪器进行单侧布置整个线圈系,根据线圈系结构设计要求,利用感应测井原理,建立发射线圈到接收线圈的响应关系,可得到应用于三分量感应测井仪器探头的响应计算。本方法简单有效,为设计三分量线圈系提供理论基础,并且能够很好地比对实际信号与理论计算的响应一致性,对多分量感应测井仪器的线圈系优化设计具有非常好的参考价值。

This structure based on three orthogonal coils,one side of the instrument layout of the coil system,according to structural design requirements of the coils,using induction logging principle,a transmitting coil to the receiver coil response relationship,get used in three-component induction measurements Response of the probe instrument well.The method is simple and effective,three-component coil system design provides a theoretical basis and is well than the actual signal in the theoretical calculation of the response to the consistency of multi-component induction logging tool coil system optimization design has very good reference value.
