摘　　要：寒武系牛蹄塘组是中国南方页岩气资源的重要层系之一,特别是在贵州省的黔南坳陷区域,牛蹄塘组的黑色页岩以其高有机质含量和深水沉积环境而闻名。本文将分析介绍牛蹄塘组页岩气资源的地质背景、岩相特征、沉积环境与有机质耦合关系,结合牛蹄塘组的热演化程度与储层特征,探索页岩气资源的形成及其分布特征。通过对已有研究的整合,旨在揭示黔南坳陷页岩气资源的勘探潜力,并提供相关技术开发建议。The Cambrian Niutitang Formation is one of the most important shale gas-bearing strata in southern China,especially in the Qiannan Depression of Guizhou Province,where the black shales of the Niutitang Formation are renowned for their high organic content and deep-water depositional environment.This paper analyzes the geological background,facies characteristics,sedimentary environment,and the coupling relationship between organic matter and the Niutitang Formation.By integrating the thermal maturation degree and reservoir characteristics,the formation and distribution characteristics of shale gas resources are explored.This study aims to reveal the exploration potential of shale gas resources in the Qiannan Depression and provide recommendations for technical development.
