发明名称 DISTRIBUTED TEMPERATURE SENSING WITH BACKGROUND FILTERING
摘要 A method for determining information about points in a wellbore that includes a region of interest comprises a) providing a first set of measured temperature data corresponding to a comparison portion of the wellbore that is not in the region of interest and a second portion of the wellbore that is in the region of interest, b) providing a second set of measured temperature data also corresponding to the comparison and second portions of the wellbore, c) on a microprocessor, using the comparison portions of the first and second data sets to align the first and second data sets, d) subtracting the second portion of the first data set from the portion of the second data set with which it is aligned, and e) outputting the result of step d) as human-readable information about points in the region of interest.
