Abstract
By applying high-definition induction logging (HDIL), we can precisely obtain flushed zone, transitional zone, and true formation resistivity profiles. HDIL has a distinct advantage in oil and water bed identification. However, when there is a low resistive zone in the reservoir, array induction logging is disabled to identify fluid. Two-parameter recognition was modified, which has a perfect effect in recognizing low-resistivity oil layer and low-resistivity belt zone; accuracy was 100 %. Two-parameter method supplies technological support in finding subtle oil layer and provides ideas for other array logging as well.
