Imaging logging is a method of imaging the physical parameters of the borehole wall and the objects around the well according to the observation of the geophysical field in the borehole. It is a basic subject of geography. In a broad sense, imaging logging should include borehole imaging, borehole edge imaging and inter well imaging.
Borehole imaging logging technology is the most mature, including borehole acoustic imaging and formation micro resistivity scanning imaging.
Borehole edge imaging is mainly resistivity imaging, and the methods used are azimuthal lateral logging and array induction logging. Cross well imaging, including acoustic, electromagnetic and resistivity imaging, has been widely used in engineering exploration and has obtained some successful examples in oil exploration.
