摘要
In order to correct the anisotropic resistivity for horizontal well logging in thin interlayer oil reservoir, firstly the crossing points of the horizontal well track with target formations were determined by analyzing the response characteristics of logging parameters, and a series of virtual vertical wells at these locations were set to get an accurate 3D lithology model adapting the horizontal well track survey. Secondly, a 3D relative resistivity anisotropic coefficient volume was calculated based on the deep resistivity measured from neighbouring vertical control wells for target formations. Finally, the horizontal resistivity logging for varying angles between the well track and formation beddings was calculated.
