摘　　要：东营凹陷盐家油田砂砾岩体为快速堆积而成的近岸水下扇沉积,内部结构复杂,岩性多样复杂,利用常规测井资料识别岩性困难,岩性识别为制约该地区勘探开发的难题之一。从岩心观察描述入手、在岩性、物性、电性、含油性特征研究的基础上,利用岩心、成像资料精确标定常规测井资料,建立了一整套识别砂砾岩储集层岩性的方法和标准。该方法能有效识别岩性,在胜利盐家油田首次引进并使用该方法就取得了良好的效果,与岩心对比吻合率达90%。该方法对类似油气藏研究同样具有指导意义。Sand- gravelrock body in Yanjia oilfield of Dongying sag is a kind of nearshore subaqueous fan with characteristics of complex internal structure,lithology diverse and complex. The use of conventional logging lithology identification was difficult,and lithologic constraints identified have one of the problems in the area of exploration and development. In this paper,description starting from core observation,based on lithology,physical properties,electrical properties,oil characteristics,a set of identification glutenite reservoir lithology method and standard was established with the core and imaging data accurate calibration of conventional logging data. This method can effectively identify lithology,introduced for the first time in Shengli Yanjia oilfield and good results have been achieved using this method with core self- agreement amounted to 90%. The method also has guiding significance for similar reservoir study.
