摘要
李洪奇，刘洪，李幼铭．井间电磁场伪地震波场成像方法．测井技术，１９９９，２３（２）：１２０～１２２描述了井间电磁波场到伪地震波场的转换理论和方法，采用地震波的射线理论和射线方法完成了伪地震波场的速度成像。当介质磁导率恒定时，伪地震波场的速度与介质电导率的平方根成正比。因此，伪地震波场的速度图像实际上反映了介质的电学特性。
The method and theory by
which crosswell electromagnetic field is transformed to pseudo seismic wavefield are
described in this paper. Velocity imaging of pseudo seismic wavefield is completed in
the light of ray tracing and traveltime inversion. From wavefield transform theory the
velocity of pseudo seismic wavefield is proportional to the square root of media
conductivity. In fact, the result of velocity imaging reflects the electrical characteristics
of media. These are illustrated by examples of numerical computation in the paper.
