摘　　要：大牛地气田上古生界自然伽马曲线划分为四种基础测井相类型:钟形、漏斗形、箱形和指形。基础测井相在垂向上可出现六种不同测井相类型组合:漏斗形+钟形、钟形+漏斗形、钟形+箱形+漏斗形、钟形+箱形、箱形+指形和指形+箱形,基础测井相及其垂向上的不同组合反映相应的沉积微相。Gamma ray curve of the Upper Paleozoic in Daniudi gas field can be divided into 4 basic electrofacies types, including bell - shaped, funnel-shaped, box-like and finger - like electrofacies. Vertically, the basic electrofacies can occur in 6 different electrofacies combinations, including funnel - shaped + bell - shaped, bell -shaped + funnel-shaped, bell - shaped + box - like + funnel - shaped, bell- shaped + box-like, box-like + finger-like and finger - like + box - like. The basic electrofacies and their variant combinations reflect corresponding sedimentary microfacies.
