摘要: 依据松辽盆地三肇地区27口探井的644块取心岩样自然伽马能谱数据,以及室内测量和分析的岩样岩性参数,讨论了该地区的放射性核素Th、U和K的分布规律,并从地质和物理条件入手,建立了自然伽马能谱与泥质含量、粒度中值、阳离子交换量、铝-硅比等岩性参数以及粘土类型的数学关系,为该地区的地层评价和自然伽马能谱测井资料解释,提供了充分的理论依据.

Abstract: In the light of natural gamma ray spectrometry(NGS) data obtained from 644 pieces of core samples of 27 exploratory wells and lithologic parameters of these rock samples tested and analyzed in the laboratory.the distribution regularities of radioactive elements,Th,U,and K,in the region are discussed. Proceeding from geological and physical conditions,mathematical relations between gamma ray spectrometry and lithologic parameters such as shaliness,mid-value of grain size,cation exchange level,the ratio of aluminium to silicon,etc.are established.This provides a full theoretical basis for the evaluation of formations and for the interpretation of well logging data of natural gamma ray spectrometry in the region.
