Abstract
The underground reservoir is an important index for comprehensive evaluation of regional geological conditions.Through the analysis of the correlation and similarity between the underground effective reservoir and the underground compressed gas energy storage area,the geological conditions of the underground compressed gas energy storage area can be obtained by using the seismic geophysical comprehensive logging curve method.Firstly,through combing the seismic data,the reflection characteristics of seismic profile are analyzed,and the regional geological structure and its evolution are comprehensively understood with seismic sedimentology;Then,by using the fitting relation between the integrated logging curves,the defects of the exploration data can be made up and the effective acoustic curves can be reconstructed;In addition,the shape of the fitting curve is combined with the seismic reflection characteristics to perform horizon calibration and fine interpretation;Finally,the K-means clustering method is used to calculate the wellhead samples and the geological model is established by using JASON8.4 software.By matching the statistical results of wellhead samples with seismic attributes,the regional underground reservoirs are classified,and the type of effective underground reservoirs and the type Ⅱ reservoir area of the most favorable distribution area are determined,the type Ⅱ reservoir area is the site selection area of underground compressed gas energy storage.关键词
