摘要
粘土矿物是储集层的重要组成部分,其含量及特性对油田开发效果有着较大的影响。自然伽马能谱测井不仅可以测得地层的总自然伽马值,同时还能得到地层的铀、钍、钾含量。该文对利用自然伽马能谱资料识别和确定粘土矿物类型以及储集层中的粘土矿物含量作了初步的探讨。
Clay mineral is an important component part of reservoir, and its content and feature have a great effect on oil field development. The identification of the clay mineral types by using natural gamma-ray spectroscopy log method was discussed. The result showed that using natural gamma-ray spectroscopy log could not only identify the types of the clay mineral, but also determine the content of the clay mineral in the reservoir, which could provide effective reference for the development plan of oil field.
