摘　　要：通过对研究区域的复杂砂砾岩体岩心、录井、测井等数据的综合分析,预先落实部分岩性,选择对储层岩性敏感的自然伽马、电阻率、补偿中子和声波时差4种曲线进行曲线重构,建立了一套岩性识别图版,确立各类岩性定量解释标准。结果表明,该方法能定量划分储层岩性,可为研究区后续的勘探开发提供参考的岩性数据。Based on the comprehensive analysis of core,mud logging,logging and other data,part of the lithology is determined in advance,a set of lithologic identification charts suitable for the study area are established by reconstruction of four kinds of logging curves sensitive to reservoir lithology,namely,natural gamma,resistivity,compensated neutron and acoustic time difference,and various lithologic quantitative interpretation standards are established.The application results show that this method can divide reservoir lithology quantitatively and provide reliable lithologic data for subsequent exploration and development in the study area.
