随着钻井工艺的发展和非常规勘探开发的深入,对录井技术的发展提出了更高的要求,需要开发、推广新的录井技术识别和评价非常规储层。伽马能谱录井技术可测量岩屑中的铀(u)、钍(Th)、钾(K)的含量,能够辅助识别岩性,判识储层中的粘土矿物类型,定量计算泥质含量,为录井非常规储层的评价提供了依据,具有较好地应用前景。
With the development of drilling technology and unconventional exploration and development, higher requirements are put forward for the development of logging technology. New logging technologies need to be developed and promoted to identify and evaluate unconventional reservoirs. Gamma spectrometry logging technology can measure uranium (u), thorium (Th) and potassium (K) in cuttings and can help identify lithology, identify clay mineral types in reservoirs, and quantitatively calculate argillaceous Content, provides a basis for the evaluation of unconventional reservoir logging, has a good prospect of application.
