Reservoir fluid identification method based on well logging curve normalization processing

Abstract

The invention discloses a reservoir fluid identification method based on well logging curve normalization processing, and the method specifically comprises the following steps: 1, obtaining a well logging curve graph, and carrying out the preprocessing of the data of the well logging curve graph, and obtaining a data effective range; 2, analyzing a logging curve, and removing logging response anomalies; step 3, performing normalization processing on the logging curve needing to be normalized; and step 4, unifying the normalized data to the same scale of 0-1, and performing comparison and analysis. According to the method, the numerical values of the different well logging curves after normalization processing are analyzed, measurement errors between different wells are eliminated, the well logging curves change more obviously, and therefore the accuracy and reliability of gas reservoir recognition are improved.
