摘要
碳氧比能谱测井是一种探测地层化学指示元素比值的核测井方法。根据测量的碳氧比(C/O)和硅钙比(Si/Ca),可以确定套管井地层含水饱和度及其产水率。从80年代起,我国大庆、胜利、辽河、大港油田先后开展了碳氧比能谱测井,在套管井地层中找油找气,获得了显著的地质效果。本文论述碳氧比能谱测井解释油气水层的方法基础及油田应用实例。
Carbon/oxygen spectral log is a nuclear logging method for detecting
chemical indicator elements in strata. Based on surveyed C/O ratios and Si/Ca
ratios, we can determine water saturation and water cut of strata in cased
well.
Since the beginning of 1980's, carbon/oxygen log has been performed in such
oil fields of China as Daqing, Shenli, Liaohe and Dagang with satisfactory
geologic results achieved. In this paper the fundamentals and rield application
examples of the carbon/oxygen spectral logging method for interpretation of
hydrocarbon and water zone are discussed in detail.
