感应测井的复视电导率

Complex Apparent Conductivities of Induction Well Logging

本文引出和定义了感应测井的复视电导率,在不同电导率的均质地层中,复视电导率比传统定义的视电导率更接近于真电导率。本文还计算和讨论了三层不同电导率地层在各种情况下的复视电导率,并指出薄层的相位跳跃在薄层探测中可能得到应用。

Complex apparent conducfivities of induction Well logging tools are introduced and defined. The behaviours of the complex apparent conductivities in homogeneous layers with different conductivities appear closer to the true conductivifies than those of the conventionally defined apparent condutivities. The complex apparent conductivities of three layers in different cases are calculated and discussed. The phase jumping of the thin beds might be useful in detecting the thinner beds.
