摘　　要：依托山东省章丘—邹平地区地表基质层调查项目,介绍了综合测井技术在地表基质层分层中的应用效果。通过测量井中视电阻率、自然伽马、自然电位等测井参数,综合计算地层中的泥质含量,对地表基质层进行了厚度分层,总结了3种测量参数发挥的主要作用。视电阻率主要用于划分地层、岩性和含水层,确定其厚度;自然伽马主要用于确定地层泥质含量,配合其他方法划分含水层、岩性及判断裂隙发育程度;自然电位主要用于判断岩性和划分渗透层,配合自然伽马测井估计泥质含量。实践表明,综合测井技术中以上3个测井参数相互配合,计算得出的泥质含量曲线可对地层进行精细解释,在相似地区地表基质层调查中可进行推广应用,为地表基质层调查技术方法体系的建立提供了支撑。Based on the investigation project of surface matrix layers in Zhangqiu-Zouping area in Shandong province,the application effect of comprehensive logging technology in the stratification of surface matrix layers has been introduced.By measuring the logging parameters,such as apparent resistivity,natural gamma,and natural potential in the well,the shale content in the formation has been comprehensively calculated,and the thickness of the surface matrix layers has been stratified.The main functions of three measurement parameters have been summarized.Apparent resistivity is mainly used to divide strata,lithology and aquifers and determine their thickness.Natural gamma is mainly used to determine the shale content of the formation.Combining with other methods,the aquifer,lithology and the degree of fracture development have been deternined.The natural potential is mainly used to judge the lithology and divide the permeable layer,and to estimate the shale content with natural gamma logging.It is showed that the above three logging parameters in the comprehensive logging technology cooperate with each other,and the calculated shale content curve can be used for fine interpretation of the formation.It can be popularized and applied in the investigation of surface matrix layers in similar areas.It will provide support for the establishment of technical method system of the investigation of surface matrix layers.
