摘　　要：为了配合三维感应测井仪器的开发,指导其刻度装置的设计,研究采用三维有限元法编制了三维感应测井响应数值模拟程序,模拟单一倾斜刻度环下的刻度响应,考察了刻度环半径、刻度环电阻、刻度环倾斜角度、刻度环倾斜方位、刻度环水平放置位置对仪器响应的影响,与物理实验进行了相互验证。分析结果证明了所建立的数值模拟算法的正确性,得到了给定的三维感应线圈系和刻度环半径条件下的最优倾斜角、倾斜方位、刻度电阻和水平放置位置。Abstract： For the 3D induction logging tool development and its calibration instrument design, a 3D finite element method is used to program the 3D induction logging response simulation program. The response of single tilt calibration ring is discussed. The effects of ring＇s radius, resistance, tilt angle, azimuth and position on the response are detailed and verified by physical experiments. The result indicates that the numerical modeling is correct. The optimal values are determined of ring＇s resistance, tilt angle, azimuth and position for the 3D induction sonde and calibration ring radius.
