Establishment of a Well Logging Curves Normalization in Daqingzi Oilfield

摘要

After environmental correction, logging data still has the system deviation caused by different logging tools' calibration between logging suites and the factors of manipulate. In order to reduce the effect of not-geological factor to the logging data, according to the characteristics of the area, mainly using tendency surface analysis method, the correction method of combined with frequency of distribution histogram method and mean correction method as auxiliary to standard the logging data (taking sonic logging curve for example) of Putaohua Reservoir in the north of Jilin Daqingzi oilfield. Compared with the physical property of coring wells before and after the correction, the combined correction method can provide accurate basic data for log interpretation which is more suitable for the studied area than using either the frequency of distribution histogram method or the tendency surface method alone.
