Abstract:Micro-resistivity imaging logging plays an important role in the reservoir evaluation and the study of sedimentary facies and structures. However, its measurement values are not calibrated exclusively. Besides, the utilization of shallow lateral well logging (LLS) or spherical focusing logging (SFL) data to calibrate micro-resistivity imaging logging values is not accurate enough. This paper introduces a basic principle of Linear Four-Probe and uses four-probe device (ST2258C) to prove its validity. Moreover, it presents a workflow to calibrate the resistivity of imaging logging.
