摘要
基于成像、元素俘获和常规测井资料,从胜利油气区泥页岩地层岩相分析入手,总结不同岩相泥页岩的测井响应特征,以及与储集质量和含油性的关系。引入岩性系数的概念,建立碳酸盐岩、砂岩、黏土岩质量分数的计算模型。根据测井曲线的形态特征,提出岩层结构分类方法,实现了根据岩石质量分数和结构特征连续自动判别泥页岩岩相,收到良好的应用效果。
Based on imaging logging,ECS,and conventional logging data,and analysis of shale lithofacies of Shengli Oilfield,the logging response characters of different shale litho-facies and the relationship between reservoir quality and oil-bearing property were summarized.The concept of litho-parameter was introduced to establish carbonate content model,sand content model,and shale content model.A new shale rock structural classification methodology is put forward by using logging curve shape,automatic shale lithofacies classification is realized,and good result of application is achieved.
