摘要 已发现的油藏中，各向异性油藏占总油藏的20％～30％，但常规电磁测井仪只能测量水平方向的电阻率，很容易低估和漏测产层．三分量感应测井仪通过布置三组相互正交的发射一接收线圈对可直接测量地层的水平电阻率和垂直电阻率，通过测量两个交叉分量还可得出地层的倾角和方位．避免了时产层的低估和漏测．本文介绍了各向异性地层的主要类型，各向异性电阻率的计算公式，三分量感应测井仪的线圈系结构，多频聚焦方法以及包含围岩校正的反演方案． Anisotropie reservoirs occupies 20%～30% of total reservoirs. However, conventional induction logging tool measures only horizontal resistivities. This may result in an underestimation of ＂low resistivity, low contrast＂ shale sand layers. A muhicomponent induction logging tool provides direct measurements to derive both horizontal and vertical resistivities by setting three mutually orthogonal transmitter-receiver coil configurations, and it also provides relative dip and tool orientation data by measuring two crosscomponents,and it avoids underestimation or omittance of reservoirs . This paper studies the main types of anisotropic formation, the formulae of anisotropic resistivities, the configuration of coil array of the multicomponent induction logging tool, multl-frequency focusing method and the inversion scheme included shoulder bed corrections.
