摘要
Abstract
The logging curve repeatability of DIL5520 dual induction logging tool is unsatisfactory in high resistivity formation because of the temperature excursion in logging. Conventional induction logging tool with bad repeatability is due to its configuration, but for DIL5520 dual induction logging tool, we can improve its stability by changing warming processes. Proposed is 4 ways to improve its repeatability:① increase 100 "C reporting spot; ② keep each temperature for 30 min; ③ fully soap the coil array in silicone oil before warming the tool, and do software temperature compensation, etc. To solve the problems such as abnormal log values and unsatisfactory curve repeatability in middle and high resistivity formation logging with the DIL5520 tool, the ideal solution is to put several emission and receiving coils downhole to improve its detection performance. For induction logging, we should assemble centralizer according to regulation to ensure logging curve repeatability. As for wells with bigger borehole diameter, the calibration chart is needed to guarantee the log data correction.关键词
