It is impossible to accurately obtain water injection profile data of macropore formation during radioisotope tracer logging operation.
对于大孔道地层,放射性同位素示踪测井无法准确地录取注水剖面的资料,一些生产单位提出了结合放射性同位素示踪测井和电磁流量计测井的方法解决大孔道注水剖面测井资料录取问题,本文对该测井方法的解释问题进行了研究,取得了较好的解释效果。
In this paper, the radioactive isotope dating method is used to study the modern sedimentation rates of 6 cores from the Dachan Bay, Pearl River estuary, and the grain size analysis at intervals of 2 mm is also made for the upper parts of two cores.
采用放射性同位素测年方法研究了珠江口伶仃洋大铲湾海域6个柱样的现代沉积速率,以2mm的间隔分析了其中2个柱样上部的粒度,并对其平均粒径和珠江流域的年输沙量进行了快速傅里叶变换,以期获取河流泥沙供应、河口沉积速率和沉积物垂向粒度变化的对应关系。
