摘　　要：地下储层是综合研判区域地质条件好坏的重要指标。通过分析地下有效储层与地下压气储能区两者间的相关性和相似性,采用地震物探综合测井曲线方法,可分析得知地下压气储能区的地质情况。首先,通过梳理地震资料,初步分析出地震剖面反射特征,结合地震沉积学对区域地质构造及其演化进行全面认识;随之,利用综合测井曲线间的拟合关系,弥补勘探资料的缺陷,重组出有效的声波曲线;此外,将拟合曲线形态与地震反射特征相结合,进行层位标定和精细解释;最后,采用K-means聚类方法对井口样品统计,利用Jason8.4软件建立地质模型。通过井口样品统计结果与地震属性相匹配,将区域地下储层归类,确定地下有效储层类型和最有利分布区Ⅱ类储层区,Ⅱ类储层区即为地下压气储能选址范围。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.
