[0002] As oilfield exploration progresses, understanding formation anisotropy and measuring thin layers and shale gas have become crucial. Traditional array induction logging instruments can only measure the horizontal resistivity of formations, easily missing, underestimating, or even misjudging anisotropic reservoirs. Due to its unique coil system structure, array induction logging instruments offer unparalleled advantages over other instruments, enabling precise evaluation of reservoir physical properties.

In particular, there is a very urgent need for well logging instruments with high resolution and deep detection. However, there are many difficulties in designing and developing such well logging instruments.
