    摘要: A borehole resistivity instrument for use in a borehole drilled within a geologic formation includes an emitting electrode and an imaging electrode. The borehole resistivity instrument also includes a current isolator positioned between the emitting electrode and the imaging electrode. The current isolator prevents a substantial portion of the electric current emitted from the emitting electrode from passing to the imaging electrode through the borehole.
