摘要： ECS 测井是元素俘获测井的简称, 它可以定量提供地层中的Si、Ca、Fe、S、Ti、Gd 等化学元素的含量。利用这些元素与地层岩性之间的相关关系以及提供的岩石矿物含量, 可以确定不同的岩性、进行地层对比, 修订地层的孔隙度、含油饱和度等参数。该方法在彩31 井区的岩性识别方面得到的岩性与钻井取心描述的岩性有较好的一致性; 用ECS 给出的岩性剖面和元素含量, 结合常规测井资料, 能进行更为细致的地层对比; 用ECS 各种元素变化特征识别沉积环境、进行沉积分析等方面获得了较好的认识和成果。

Abstract: Element capture service (ECS) can be applied to quantitative determination of the contents of Si, Ca, Fe, S, Ti, Gd in stratum. The correlation of these elements and lithology and given rock mineral contents can be used for distinct lithology and strata correlation as well as porosity and oil saturation corrections. This technique has been applied to Well block Cai-31 for lithology identification, and a good accordance between ECS's lithology and core-describe lithology is gained. The study shows that using ECS lithological profile and element content integrated with conventional well log data, the strata correlation, sedimentary environment recognition and deposition analysis could be conducted in more detail.
