Abstract: Accurate measurement of resistivity of sand-mudstone thin interaction layer is an important task
in improving the calculation of argillaceous sandstone reservoirs. In order to solve the problem of accurate
measurement of thin interaction layer resistivity, this paper proposes a design and implementation method
of 3D induction imaging logging tool. First, based on the inductive electromagnetic measurement method, a
3D detector consisting of a three-axis emitter, four single-axis receiving arrays and three three-axis receiving
arrays is designed. On this basis, through the 3D coil system parameters and structural innovation design, high-
performance transmission and reception integration, multi-frequency cyclic transmission, high-precision multi-
channel synchronous acquisition and other technologies, 78 conductivity measurements are available at each
depth point. Finally, data correction and processing techniques are used to eliminate various environmental
impacts, and the results of theoretical models and actual data are confirmed that in addition to effectively
providing array resistivity curves for five different depths of detection and three different longitudinal resolutions
of induction logging tools, the instrument can also obtain formation information parameters such as formation
horizontal resistivity, vertical resistivity, formation dip angle and azimuth angle, which effectively solves the
problem of accurate measurement of resistivity of sand-mudstone thin interaction layer.
