测量地层垂直电导率的感应线圈系设计

Design of Induction Coil System to Measure the Formation Perpendicular Conductivity

三维感应测井仪器提供一种测量水平和垂直电导率的三轴正交线圈系。通过形成在X方向、Y方向的线圈板的主体插入Z向线圈绝缘体的安装面的孔,使得三轴发射线圈阵列和接收线圈阵列的X、Y和Z轴分别正交到一个点上。由此在测井时使X向、Y向、Z向线圈组成独立的三轴线圈,确保每一个线圈的9个分量的位置均相同。

Three dimension induction logging instrument provides three axis orthogonal coil system to measure the horizontal and vertical conductivity. The X direction and Y direction of the coil plate main bodies are inserted to the mounting surface holes of the Z direction coil insulator, so that the three shafts transmit coil array and the receiver coil array X, Y and Z axes are orthogonal to one point. When logging, the X direction, Y direction and Z direction coils form an independent three axis coil, ensuring that the 9 component positions of each coil are the same.
