Simulation Analysis of Soft Focusing of Azimuth Laterolog Resistivity Imaging LWD Tool

Simulation Analysis of Soft Focusing of Azimuth Laterolog Resistivity Imaging LWD Tool

When logging while drilling directional lateral instruments work in formations, due to the long length of the drill collar, the surface potential attenuation is severe. The current flowing out of the drill collar will produce axial components, which cannot flow out strictly perpendicular to the surf...
